ABSTRACT:
An optical device emitting light of a predetermined mixed color other than the intrinsic colors of light emitting layers from each pixel having a reduced number of drive lines (electrodes) to achieve the color. The optical device includes one or a plurality of self light emitting elements, each corresponding to one pixel and including a pair of electrodes formed on a substrate and at least a light emitting layer between the electrodes. The light emitting layer includes a first layer with a first region that emits light of a first color and a second layer with a second region that emits light of a second color that is different from the first within the same opening of each pixel. A third light emitting region is formed within the opening for emitting light of a color that is a mixture of the first color and the second color.
