Display apparatus
View Patent ↗A display apparatus that includes: a plurality of light-emitting devices disposed on a substrate with an accumulation of, in this or inverse order, a light transmissive electrode layer, a functional layer including a light-emitting layer, and an opposing electrode layer; and a color conversion layer that is provided on a side of the light transmissive electrode layer for any of the light-emitting devices, and applies color conversion to an emitted light generated by the light-emitting layer for the light-emitting device. In the display apparatus, the light-emitting devices each have a reflective surface on a position where the light-emitting layer is sandwiched with the light transmissive electrode layer, and an optical distance between the reflective surface and the light-emitting layer varies by the light-emitting devices depending on provision of the color conversion layer.
1. A display apparatus comprising:
a plurality of light-emitting devices disposed over a substrate having, in this or inverse order, a light transmissive electrode layer, a functional region including a light-emitting layer, and an opposing electrode layer; and
a color conversion layer that is provided at a side of the light transmissive electrode layer for at least some of the light-emitting devices, wherein
the light-emitting devices each have a reflective surface at a position opposite the light transmissive electrode layer with the functional region therebetween, and
wherein an optical distance between the reflective surface and the light-emitting layer varies among the light-emitting devices depending on whether the color conversion layer is located at the light emitting device; and further, wherein
the optical distance for any of the light-emitting devices that is not provided with the color conversion layer is set to a value with which interference occurs to the emitted light generated by the light-emitting layer of the light-emitting device, and
the optical distance for any of the light-emitting devices provided with the color conversion layer is set to a value with which a light of a predetermined wavelength as a result of conversion by the color conversion layer is extracted with the highest level of intensity.
2. A display apparatus comprising:
