Abstract

A pixel electrode used in a display device having a display layer provided between a pair of substrates, includes a first layer having a first surface in contact with the display layer, and a second layer in contact with a second surface opposed to the first surface of the first layer, wherein an electrode potential of the first layer is lower than an electrode potential of the second layer.

Claims (25)

1 . A pixel electrode used in a display device having a display layer provided between a pair of substrates, comprising:

a first layer having a first surface in contact with the display layer; and

a second layer in contact with a second surface opposed to the first surface of the first layer,

wherein an electrode potential of the first layer is lower than an electrode potential of the second layer.

2 . The pixel electrode according to claim 1 , wherein an end portion of the second layer is not covered by the first layer.

3 . The pixel electrode according to claim 1 , wherein a hole penetrating the first layer and the second layer is formed.

4 . The pixel electrode according to claim 1 , wherein a thickness of the first layer is larger than a thickness of the second layer.

5 . The pixel electrode according to claim 1 , wherein the first layer is formed using Al or an Al alloy.

6 . The pixel electrode according to claim 1 , wherein the second layer is formed using Ti or a Ti alloy.

7 . A display device comprising the pixel electrode according to claim 1 .

8 . A display device comprising the pixel electrode according to claim 2 .

9 . A display device comprising the pixel electrode according to claim 3 .

10 . A display device comprising the pixel electrode according to claim 4 .

11 . A display device comprising the pixel electrode according to claim 5 .

12 . A display device comprising the pixel electrode according to claim 6 .

13 . The display device according to claim 7 , further comprising a mounting terminal formed by the first layer and the second layer.

14 . The display device according to claim 8 , further comprising a mounting terminal formed by the first layer and the second layer.

15 . The display device according to claim 9 , further comprising a mounting terminal formed by the first layer and the second layer.

16 . The display device according to claim 10 , further comprising a mounting terminal formed by the first layer and the second layer.

17 . The display device according to claim 11 , further comprising a mounting terminal formed by the first layer and the second layer.

18 . The display device according to claim 12 , further comprising a mounting terminal formed by the first layer and the second layer.

19 . A method of manufacturing a pixel electrode comprising:

forming a second conductor layer on an insulating layer;

forming a first conductor layer of a material having an electrode potential lower than an electrode potential of a formation material of the second conductor layer on the second conductor layer; and

forming an island-shaped electrode by collectively patterning the first conductor layer and the second conductor layer.
