Abstract

A display device includes first and second substrates each including a short side and a long side, ground parts located on at least one of the short and long sides of each of the first and second substrates and including at least one first ground surfaces, which are perpendicular to opposing surfaces of the first and second substrates, and at least one second ground surfaces, which are provided at at least one edge of the second substrate to define an obtuse angle with reference to the first ground surfaces, and unevenness disposed on the first ground surfaces along a first direction, where the unevenness defines an acute angle with reference to a normal line to the opposing surfaces.

First claim

What is claimed is:

1. A display device, comprising:
first and second substrates facing each other to define opposing surfaces, each of the first and second substrates including a first side surface and a second side surface; and
a ground part located on the first side surface of the first substrate or on the first side surface of the second substrate and including at least one first ground surface, which is perpendicular to the opposing surfaces,
wherein the at least one first ground surface has a plurality of grooves,
wherein each of the plurality of grooves is substantially extended in a first direction which defines a first angle with reference to a normal line to the opposing surfaces, and
wherein the first angle is an acute angle.

2. The display device of claim 1 , wherein the at least one first ground surface does not have any groove extended in a second direction which intersects the first direction.

3. The display device of claim 1 ,
wherein the ground part further includes at least one second ground surface, which is tilted from the at least one first ground surface at a second angle.

4. The display device of claim 3 , wherein the first side surface of the first substrate or the first side surface of the second substrate includes the at least one first ground surface and does not include the at least one second ground surface.

5. The display device of claim 3 , wherein the ground part is further located on the second side surface of the first substrate or the second side surface of the second substrate.

6. The display device of claim 5 , wherein the at least one second ground surface is located at a top of the second side surface of the second substrate or at a bottom of the second side surface of the first substrate.

7. The display device of claim 3 , wherein the second angle is about 80 degrees to about 170 degrees.

8. The display device of claim 3 , wherein:
each of the first and second substrates further includes a third side surface opposite to the first side surface,
the ground part is further located on the third side surface of the first substrate or the third side surface of the second substrate, and
the third side surface of the first substrate or the third side surface of the second substrate includes both the at least one first ground surface and the at least one second ground surface.

9. The display device of claim 8 , wherein the first side surface of the first substrate or the first side surface of the second substrate includes the at least one first ground surface and does not include the at least one second ground surface.

10. The display device of claim 9 , wherein the at least one second ground surface is located at the top of the third side surface of the second substrate and the bottom of the third side surface of the first substrate, respectively.

11. The display device of claim 1 , wherein the first angle is about 30 degrees to about 80 degrees.
