Abstract:
1. A display device comprising: a substrate; a plurality of light-emitting elements formed on the substrate; and a reflective layer disposed between the substrate and the light-emitting elements and reflecting lights emitted from the light-emitting elements, wherein the light-emitting elements each include a transparent layer that is in contact with the reflective layer, a light-emitting layer disposed on the upper surface of the transparent layer, and an electrode layer with transparency disposed on a side of the light-emitting layer opposite the side on which the reflective layer lies, the distance between the reflective layer and the electrode layer in each of the light-emitting elements is set such that a light component of a specific color in the light emitted from the corresponding light-emitting layer is enhanced by interference and emitted from the electrode layer, and the light-emitting elements include at least first light-emitting elements and second light-emitting elements in which blue and red light components in the light emitted from the light-emitting layers are simultaneously enhanced and emitted from the electrode layer, the light-emitting elements further include third light-emitting elements in which a green light component in the light emitted from the light-emitting layers is enhanced and emitted from the electrode layers, and the distance between the reflective layer and the electrode layer in each of the third light-emitting elements is set such that the green light component is enhanced, wherein color filters that allow passage of only blue light are disposed at a light-emitting side of the electrode layers in the first light-emitting elements, color filters that allow passage of only red light are disposed at a light-emitting side of the electrode layers in the second light-emitting elements, and blue and red transparent pixel electrode layers having substantially the same thickness and both having a greater thickness than a green transparent pixel electrode layer.
