Abstract

A display device a display region arranged with a plurality of pixels in a matrix shape, wherein each of the plurality of pixels includes a first electrode including a first conducting layer on the first conducting layer and comprised from Mo or a Mo alloy, a second conducting layer comprised from Ag or an Ag alloy, and a third conducting layer on the second conducting layer and comprised from a metal oxide having conducting properties, the first electrode being arranged corresponding to each of the pixels respectively, a light emitting layer above the third conducting layer and emitting light according to a current supply, and a second electrode above the light emitting layer and allowing at least a part of the light from the light emitting layer to pass through.

Claims (26)

1. A display device comprising:

a display region arranged with a plurality of pixels in a matrix shape, wherein

each of the plurality of pixels comprises:

a first electrode including a first conducting layer comprised from Mo or a Mo alloy, a second conducting layer on the first conducting layer and comprised from Ag or an Ag alloy, and a third conducting layer on the second conducting layer and comprised from a metal oxide having conducting properties, the first electrode being arranged corresponding to each of the pixels respectively;

a light emitting layer above the third conducting layer and emitting light according to a current supply; and

a second electrode above the light emitting layer and allowing at least a part of the light from the light emitting layer to pass through, and

an end part of the first conducting layer and an end part of the second conducting layer are located closer to a center region of a pixel than an end part of the third conducting layer.

2. The display device according to claim 1 , wherein

the third conducting layer allows at least a part of the light from the light emitting layer to pass through.

3. The display device according to claim 2 , wherein

the third conducting layer is ITO.

4. A display device comprising:

a display region arranged with a plurality of pixels in a matrix shape, wherein

each of the plurality of pixels comprises:

a first electrode including a first conducting layer, a second conducting layer on the first conducting layer, and a third conducting layer on the second conducting layer, the first electrode being arranged corresponding to each of the plurality of pixels respectively;

a light emitting layer above the third conducting layer and emitting light according to a current supply; and

a second electrode above the light emitting layer and allowing at least a part of the light from the light emitting layer to pass through, and

an end part of the first conducting layer and an end part of the second conducting layer are located closer to a center region of a pixel than an end part of the third conducting layer.

5. The display device according to claim 4 , wherein

the first conducting layer comprises Mo or Mo alloy,

the second conducting layer comprises Ag or Ag alloy, and

the third conducting layer comprises metal oxide.

6. The display device according to claim 4 , wherein

the third conducting layer allows at least a part of the light from the light emitting layer to pass through.

7. The display device according to claim 6 , wherein

the third conducting layer is ITO.
