Abstract

A display device includes: a light emitting element layer which emits light, with luminance controlled in each of a plurality of unit pixels forming an image; a color filter layer which has colored layers of a plurality of colors, with the colored layer of one color corresponding to one of the unit pixels; a counter substrate; and an electrode of a first electrode pattern and an electrode of a second electrode pattern provided on both sides of the counter substrate, respectively, in order to detect a touch input. The colored layers next to each other are districted by a partition wall. At least a part of the partition wall in a direction of height is formed by the first electrode pattern.

Claims

1. A display device comprising:

a light emitting element layer which emits light, with luminance controlled in each of a plurality of unit pixels forming an image;

a color filter layer which has colored layers of a plurality of colors, with the colored layer of one color corresponding to one of the unit pixels;

an insulating layer; and

a first electrode and a second electrode provided on both sides of the insulating layer, respectively, in order to detect a touch input;

wherein the colored layers next to each other are districted by a partition wall, and

at least apart of the partition wall in a direction of height is formed by the first electrode.

2. The display device according to claim 1, wherein the insulating layer is made up of only one layer covering the color filter layer and the first electrode.

3. The display device according to claim 1, wherein the insulating layer includes a first layer covering the color filter layer and the first electrode, and a second layer stacked on the first layer.

4. The display device according to claim 1, wherein the partition wall has a height equal to or above a height of the color filter layer.

5. The display device according to claim 1, wherein the colored layers next to each other are separated from each other by the partition wall.

6. The display device according to claim 1, further comprising an underlying layer which includes the color filter layer and the first electrode and covers the light emitting element layer,

wherein the underlying layer has a convex part forming a bottom part of the partition wall, and

the first electrode is formed on the convex part, thus forming a top part of the partition wall.

7. The display device according to claim 1, further comprising an underlying layer which includes the color filter layer and the first electrode and covers the light emitting element layer,

wherein the underlying layer has a flat top surface, and

the first electrode is formed on the flat top surface, thus forming the partition wall.

8. The display device according to claim 1, wherein at least one of the first electrode and the second electrode is made of a transparent conductive material.

9. The display device according to claim 1, wherein at least one of the first electrode and the second electrode is made of a low-reflection metal film.
