Abstract: The optical communication system includes a transmitter including a display panel which has a curved surface and is capable of emitting light, and a transmission controller which causes the display panel to emit light representing an information signal; and a receiver including an image sensor which receives the light emitted from the display panel, and a reception controller which extracts the information signal from the light received by the image sensor. The display panel may be a transparent display panel which allows background light to pass through.

Abstract: A light-emitting element includes: a light-reflective first electrode; a light-emitting layer above the first electrode; a light-transmissive second electrode above the light-emitting layer; a first light-transmissive layer on the second electrode; and a second light-transmissive layer on the first layer. First optical cavity structure is formed between surface of the first electrode facing the light-emitting layer and surface of the second electrode facing the light-emitting layer. The first optical cavity structure corresponds to, as peak wavelength, first wavelength longer than peak wavelength of light emitted from the light-emitting layer. Second optical cavity structure is formed between the surface of the first electrode facing the light-emitting layer and an interface between the first layer and the second layer. The second optical cavity structure corresponds to, as peak wavelength, second wavelength shorter than the first wavelength. The first and second layers differ in refractive index from each other by 0.3 or greater.

Abstract: A light-emitting panel includes a plurality of pixels, a plurality of first regulators, and a plurality of second regulators. The plurality of first regulators extends in a first direction and defines each two of the pixels that are adjacent to each other in a second direction orthogonal to the first direction. The plurality of second regulators extends in the second direction and defines each two of the pixels that are adjacent to each other in the first direction. The plurality of pixels at least includes a first pixel and a second pixel that have different lengths in the first direction from each other and share a light-emitting layer. The first pixel and the second pixel are at least adjacent to each other in the first direction with the second regulator being interposed between the first pixel and the second pixel.
