BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to the technical field of display devices, and specifically to a display panel.

2. Related Art

Currently, in the processes of manufacturing the display panel, after a sealant is coated onto one substrate, two substrates are often vacuum laminated, then the sealant is cured via a curing process such as ultraviolet and high temperature, and finally the substrate is cut. Structural design of a narrow bezel architecture causes that position of a cutting line and design space of the sealant are limited, so the uncured sealant easily flows to the cutting position, thereby affecting a cutting process of the panel, and residue of the sealant makes peeling of the panel impossible after cutting. If a large distance is reserved for an edge of the sealant and the cutting line, a ratio occupied by a display region of the display panel after cutting is limited, which does not facilitate production of light and thin liquid crystal panels, and also results in waste of the substrate.

SUMMARY OF THE INVENTION

An object of the invention is to provide a display panel for solving the problem of difficult peeling of the panel after cutting because the sealant of the current display panel spills into the wire out region.

To achieve the above object, the display panel of the invention has a display region and a wire out region on one side of the display region, and comprises: a first substrate including a main body part and a glue blocking part connected to the main body part, a thickness of the main body part being different from a thickness of the glue blocking part; a second substrate opposite to the first substrate; and a sealant arranged between the first substrate and the second substrate, and located between the display region and the wire out region, wherein the glue blocking part is located on one side of the sealant close to the wire out region.

In one embodiment of the display panel, the first substrate is made of glass.

In one embodiment of the display panel, the thickness of the main body part is greater than the thickness of the glue blocking part.

In one embodiment of the display panel, a width of the glue blocking part is from 50 μm to 150 μm.

In one embodiment of the display panel, the first substrate further comprises a peripheral part, the glue blocking part is connected to the main body part and the peripheral part, and a thickness of the peripheral part is greater than the thickness of the glue blocking part.

In one embodiment of the display panel, the thickness of the peripheral part is identical with the thickness of the main body part.

In one embodiment of the display panel, the thickness of the main body part is less than the thickness of the glue blocking part.

In one embodiment of the display panel, a width of the glue blocking part is from 50 μm to 200 μm.

In one embodiment of the display panel, the first substrate further comprises a peripheral part, the glue blocking part is connected to the main body part and the peripheral part, and the peripheral part protrudes from the second substrate in the wire out region.

In one embodiment of the display panel, the main body part has a main body inner surface facing the second substrate, and a main body side surface connected to the glue blocking part, wherein an angle between the main body inner surface and the main body side surface is greater than 90 degrees.

In one embodiment of the display panel, the peripheral part has a peripheral inner surface facing the second substrate, and a peripheral side surface connected to the glue blocking part, wherein an angle between the peripheral inner surface and the peripheral side surface is greater than 90 degrees.

In one embodiment of the display panel, the second substrate protrudes from the first substrate in the wire out region.

Advantageous effects of the invention lie in that the thickness of the main body part of the first substrate in the display panel of the invention is different from the thickness of the glue blocking part, and before curing, the sealant does not spill into the wire out region due to obstruction action of the glue blocking part, thereby not affecting a peeling process of the panel after cutting.

Hereinafter the invention is described in detail with reference to the accompanying drawings and the detailed embodiments, but the invention is not limited thereto.
