The organic EL device includes a base material, a recessed portion, a reflective layer provided along an inner face of the recessed portion, a filling layer having optical transparency, and filled and disposed at an inside of the recessed portion, with the reflective layer interposed between the recessed portion and the filling layer, a first electrode having optical transparency and provided at an upper-layer side of the filling layer, an organic layer including a light-emitting layer and provided at an upper-layer side of the first electrode, a second electrode having optical transparency and optical reflectivity and provided at an upper-layer side of the organic layer. At least a portion of an edge of the light-emitting region is positioned further inside than an edge of the recessed portion, and the reflective layer and the first electrode are in contact with each other at the periphery of the recessed portion.

An organic light emitting diode (OLED) display is disclosed. The OLED display includes a first stack having a first emission layer and a first layer. The first emission layer emits red light, green light, or blue light. The OLED display includes a second stack having a second emission layer and a second layer. The second stack emits light of a different angular spectral distribution as that emitted by the first stack. Further, a thickness of the second layer is different from a thickness of the first layer such that light emitted by the first emission layer resonates within the first stack at a first degree and light emitted by the second emission layer resonates within the second stack at a second degree, the first degree being greater than the second degree.

A display device includes a plurality of display units and a reflector. The plurality of display units emits display light representing an image to be displayed from a display screen. The reflector is disposed to face the display screen of each of the plurality of display units and reflects the display light emitted from each of the plurality of display units.
