CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0116343, filed on Sep. 20, 2019, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.

BACKGROUND

1. Field

One or more aspects of embodiments of the present disclosure relate to a display panel and a display device including the same, and for example, to a display panel having improved reliability and a reduced non-display area, and a display device including the display panel.

2. Description of Related Art

Recently, the purposes of display devices have been diversifying. In addition, as display devices have become thinner and more lightweight, their range of use has gradually been extended.

As display devices are used in various ways, their shapes may be designed in various ways. In addition, an increasing number of functions may be combined or associated with display devices.

SUMMARY

As an increasing number of functions may be combined or associated with display devices, one or more aspects of embodiments of the present disclosure are directed toward a display panel including an transmission area within a display area, inside which a camera, a sensor, etc. may be arranged, and a display device including the display panel. However, it should be understood that the embodiments described herein should be considered in a descriptive sense only, and do not limit the disclosure.

Additional aspects will be set forth in part in the description that follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments of the disclosure.

One or more example embodiments of the present disclosure provide a display panel including: a substrate including a non-display area and a display area outside (e.g., surrounding) the non-display area, the non-display area surrounding a transmission area, a plurality of display elements (e.g., organic light-emitting diodes) arranged in the display area, a plurality of first lines extending in a first direction, each including a detour portion that detours around an edge of the transmission area, and a shield layer overlapping the detour portions of the non-display area, wherein each of the plurality of first lines is located in the non-display area and includes a first conductive line or a second conductive line including the detour portion, and the first conductive line(s) and the second conductive line(s) are alternately arranged on different layers.

The shield layer may have a constant voltage.

The shield layer may not overlap (e.g., may not be over) the transmission area.

The shield layer may have a hole corresponding to the transmission area.

The display panel may further include a plurality of second lines extending in the first direction and having the same voltage as the shield layer.

The shield layer and the plurality of second lines may include the same material.

The display panel may further include a plurality of third lines extending in a second direction intersecting with (e.g., crossing) the first direction in the display area and disconnected outside the non-display area.

A distance between the first conductive line and the second conductive line closest to each other (e.g., adjacent lines) may be less than a width of each of the first conductive line and the second conductive line.

Each of the plurality of first lines may further include a third conductive line located in the display area.

The third conductive line may be arranged over the first conductive line and the second conductive line with an insulating layer therebetween, and may be connected to the first conductive line or the second conductive line through a contact hole defined in the insulating layer.

The display panel may further include a thin film transistor and a storage capacitor, each being arranged in the display area and connected to each of the plurality of display elements, wherein the thin film transistor may include a semiconductor layer, a gate electrode, and an electrode layer, the gate electrode overlapping at least a portion of the semiconductor layer, and the electrode layer being connected to the semiconductor layer, and the storage capacitor may include a bottom electrode and a top electrode, the bottom electrode including the same material as the gate electrode, and the top electrode being arranged between the bottom electrode and the electrode layer.

The first conductive line and the gate electrode may include or be formed of the same material.

The second conductive line and the top electrode may include or be formed of the same material.

The third conductive line and the electrode layer may include or be formed of the same material.

The shield layer and the electrode layer may include or be formed of the same material.

The display panel may further include a fourth conductive line arranged below the second conductive line so as to overlap the second conductive line.

The fourth conductive line and the semiconductor layer may include or be formed of the same material.

The fourth conductive line may be greater in width than the second conductive line.

The same voltage may be applied to the shield layer and the fourth conductive line.

The display panel may further include an encapsulation substrate covering the plurality of display elements and facing the substrate, and a sealing material surrounding the display area between the substrate and the encapsulation substrate.

The display panel may further include a material layer between the substrate and the encapsulation substrate, the material layer including at least one of an organic material, an inorganic material, and a conductive material, wherein the material layer may be arranged except in the transmission area.

One or more example embodiments of the present disclosure provide a display device including a substrate including a non-display area and a display area outside (e.g., surrounding) the non-display area, the non-display area surrounding a transmission area, a plurality of display elements arranged in the display area, a plurality of first lines extending in a first direction, each including a detour portion that detours around an edge the transmission area, a shield layer arranged over the detour portions in the non-display area, and a component including an electronic element corresponding to the transmission area.

The above and other aspects, features, and advantages of embodiments of the present disclosure will be more apparent from the following description, accompanying drawings, and claims.

These general and specific aspects may be carried out by a system, a method, a computer program, or a combination of a certain system, method, and computer program.
