Abstract

An image display according to one aspect of the present invention includes a light emitting unit that is located in each unit pixel area in each, emits light corresponding to an injected electric current, and includes a plurality of light emitting layers which are horizontally divided into. The plurality of light emitting layers are electrically connected in series.

Claims

1. An image display comprising:

a light emitting unit that is located in each unit pixel area in each, emits light corresponding to an injected electric current, and includes a plurality of light emitting layers which are horizontally divided, the plurality of light emitting layers being electrically connected in series.

2. The image display according to claim 1, further comprising a controller that controls an amount of electric current flowing through the light emitting unit to control a luminance of the light emitting unit.

3. The image display according to claim 2, wherein the controller includes a thin film transistor.

4. The image display according to claim 1, wherein the light emitting unit includes an organic electronic luminescent element.

5. The image display according to claim 1, wherein the plurality of light emitting layers are connected in series through a via hole.

6. The image display according to claim 1, wherein the plurality of light emitting layers are connected in series through a pad.

7. The image display according to claim 6, wherein the light emitting unit is formed on a substrate having a circuit layer covered with an insulation film, and the pad is provided on the insulation film.

8. The image display according to claim 1, wherein each of the plurality of light emitting layers has a substantially same area from which light is emitted.
