BACKGROUND

(1) Field

The invention relates to display devices and, more particularly, to display devices capable of reducing an occurrence of cracks in interconnections thereof

(2) Description of the Related Art

Display devices include a liquid crystal display device, an electrowetting display device, and an electrophoretic display device, etc. A display device may include pixels and interconnections having data lines and gate lines. The pixels and the interconnections are provided in a display panel of the display device. The pixels may be alternately connected to the data lines adjacent to the pixels for inversion driving of the display device.

Display devices have been developed to have curved portions. However, in the event that the display devices have the curved portions, interconnections on the curved portions receive tension. Thus, cracks may occur in the interconnections disposed on the curved portions, so that improved display devices and methods thereof capable of reducing an occurrence of cracks in the interconnections are desired.

SUMMARY

One or more exemplary embodiment of the invention provides display devices capable of reducing an occurrence of cracks in interconnections thereof.

An exemplary embodiment of the invention provides a display device including a display substrate, first interconnections, second interconnections, a driving circuit and a polarizing plate. The display substrate includes a bend portion which is curved with respect to an axis parallel to a first direction. The first interconnections extend in the first direction and are on the display substrate. The second interconnections are connected to the first interconnections and extend in a second direction different from the first direction. The second interconnections are on the display substrate. The driving circuit is electrically connected to the first interconnections and the second interconnections and provides driving signals to the first interconnections and the second interconnections. The polarizing plate is on the display substrate. The polarizing plate overlaps the first interconnections and the second interconnections.

The display substrate may further include a non-bend portion which is not curved with respect to the axis parallel to the first direction.

The first interconnections may include first bend interconnections on the bend portion, and first non-bend interconnections on the non-bend portion.

The second interconnections may include second bend interconnections connected to the first bend interconnections, and second non-bend interconnections connected to the first non-bend interconnections.

The second bend interconnections may include third interconnections on the non-bend portion and connected to the driving circuit, and fourth interconnections on the bend portion and connected to the third interconnections and the first bend interconnections.

The polarizing plate may include a quadrilateral region, and a protrusion region protruding from a side of the quadrilateral region. The quadrilateral region may overlap the first bend interconnections, and the protrusion region may overlap the fourth interconnections. The protrusion region may have a triangular shape, a quadrilateral shape, a polygonal shape, a circular shape, a semicircular shape or an elliptical shape.

The protrusion region may include a first protrusion protruding from the side of the quadrilateral region at a first end portion thereof, and a second protrusion protruding from the side of the quadrilateral region at a second end portion thereof. The first protrusion and the second protrusion may have the same shape or different shapes from each other. The first and second protrusions may overlap the fourth interconnections.

The first and second interconnections may be data lines, the driving signals may include data signals, and the driving circuit part may include a data driver which provides the data signals to the data lines.

The display device may further include gate lines insulated from the data lines, and a gate driver which provides gate signals to the gate lines.

The driving circuit may include a base film, and a driving circuit chip mounted on the base film. The base film may be flexible.

The display substrate may include a plurality of bend portions.

The display device may further include a lower protection film on the display substrate and opposite to the polarizing plate with respect to the display substrate. The lower protection film may have the same shape as the display substrate.
