Abstract

Disclosed is a display device. The display device includes a display panel, which includes a display area and a non-display area surrounding the display area, and a panel driver connected to the display panel in the non-display area of the display panel. The display panel includes an outer substrate configured to include a gate line and a data line that intersect with each other, an inner substrate coupled to a bottom of the outer substrate, and a reflection reduction member formed on the outer substrate to overlap at least one selected from the gate line and the data line, and configured to reduce a reflectivity of external light by a line.

First claim

What is claimed is:

1. A display device including a display panel, comprising:
an outer substrate including a plurality of gate lines and a plurality of data lines that intersect with the plurality of gate lines at one side;
an inner substrate coupled to a bottom of the outer substrate; and
a reflection reduction member formed on another side of the outer substrate to overlap at least (i) the plurality of gate lines, (ii) the plurality of data lines or (iii) the plurality of gate lines and the plurality of data lines, the reflection reduction member configured to reduce reflection of external light by at least (i) the plurality of gate lines, (ii) the plurality of data lines or (iii) the plurality of gate lines and the plurality of data lines; and
an edge sealing member at an entire side of the display panel and covering each side of the outer substrate and coming into contact with the reflection reduction member to form a static electricity path for conducting static electricity from the reflection reduction member,
wherein the edge sealing member includes a conductive member to form the static electricity path, and a light blocking material to prevent a side light leakage by total internal reflection of the inner substrate, and
wherein the edge sealing member covers each side of the inner substrate, an entire upper edge and an entire side of the reflection reduction member.

2. The display device of claim 1 , wherein the reflection reduction member comprises a non-reflective conductive pattern formed on a top of the outer substrate, and configured to overlap at least (i) the plurality of gate lines, (ii) the plurality of data lines or (iii) the plurality of gate lines and the plurality of data lines.

3. The display device of claim 2 , wherein the non-reflective conductive pattern is formed in a stacked structure including a three layer which include a first metal layer, an oxide layer and a second metal layer or in a stacked structure including a three layer which include a first oxide layer, a metal layer and a second oxide layer.

4. The display device of claim 3 , wherein the oxide layer is formed of Zn, In, or Sn-based oxide.

5. The display device of claim 3 , wherein the metal layer is formed of one metal material selected from Cu, Mo, Ti, Mo/Ti, and Cr.

6. The display device of claim 3 , wherein the reflection reduction member further comprises a protective layer formed on the top of the outer substrate to cover the non-reflective conductive pattern.

7. The display device of claim 6 , wherein,
the protective layer is formed of a single layer formed of SiNx, or
the protective layer is formed of a multilayer that includes an insulating layer formed of SiNx and a conductive layer formed of conductive oxide.

8. The display device of claim 2 , further comprising an electricity removing layer formed on the top of the outer substrate to cover the reflection reduction member, the electricity removing layer coming into contact with the edge sealing member.

9. The display device of claim 8 , wherein,
the electricity removing layer is formed of one material selected from a transparent metal oxide material, a transparent organic conductive material, and indium gallium zinc oxide (IGZO), or
the electricity removing layer is formed of a multilayer including a transparent conductive layer and a protective layer.

10. The display device of claim 1 , further comprising:
an outer cover that surrounds each side of the display panel and coming into contact with the edge sealing member to discharge the static electricity from the reflection reduction member.

11. The display device of claim 10 , further comprising an electricity removing layer formed on the top of the outer substrate to cover the reflection reduction member, the electricity removing layer coming into contact with the edge sealing member,
wherein the edge sealing member electrically connects the outer cover to at least one selected from the reflection reduction member and the electricity removing layer.

12. The display device of claim 11 , wherein the edge sealing member covers an upper edge of the electricity removing layer.

13. The display device of claim 10 , further comprising:
an electricity removing layer formed on the top of the outer substrate to cover the reflection reduction member, the electricity removing layer coming into contact with the edge sealing member; and
a conductive strap configured to electrically connect the outer cover to at least one selected from the reflection reduction member and the electricity removing layer, wherein one side of the conductive strap is covered by the edge sealing member, and the other side of the conductive strap is electrically connected to an inner surface of the outer cover through the edge sealing member.

14. The display device of claim 1 , further comprising a transparent conductive layer covering the reflection reduction member, the transparent conductive layer having at least an edge contacting the edge sealing member.

15. The display device of claim 2 , wherein the non-reflective conductive pattern has black or a chromatic color.

16. The display device of claim 15 , wherein the non-reflective conductive pattern is formed in a two-layer structure including a metal layer and an oxide layer, and has blue color.

17. The display device of claim 16 , wherein the metal layer is formed of Mo/Ti, and the oxide layer is formed of indium tin oxide (ITO).

18. The display device of claim 15 , wherein the non-reflective conductive pattern is formed in a three-layer including a first metal layer, an oxide layer and a second metal layer, and has the black color.

19. The display device of claim 18 , wherein the first metal layer is formed of Cu, the oxide layer is formed of indium tin oxide (ITO), and the second metal layer is formed of Mo/Ti.
