摘要:
A lightening apparatus includes light-emitting elements arranged in a matrix. One of the light-emitting elements is located at each intersection between at least two first reference voltage lines and “n” first drive voltage lines. A first reference voltage driver time-divisionally switches the first reference voltage lines. A first drive voltage driver supplies first luminous drive voltages to the first drive voltage lines. One of the light-emitting elements is located at each intersection between at least one second reference voltage line and “n” second drive voltage lines. A second reference voltage driver switches the second reference voltage line. A second drive voltage driver supplies second luminous drive voltages to the second drive voltage lines.

摘要:
A semiconductor light-emitting device, and a method for manufacturing the semiconductor light-emitting device, in which light propagating through a light-emitting layer and reaching an edge surface of a semiconductor film can be extracted to the exterior in an efficient manner. The semiconductor light-emitting device comprises a semiconductor film including a light-emitting layer made from a group III nitride semiconductor. The semiconductor film has a tapered edge surface inclined diagonally with respect to a light extraction surface. The light extraction surface has a relief structure comprising a plurality of protrusions having a shape originating from the crystal structure of the semiconductor film. The average size of the protrusions in a first region in the vicinity of an edge section of the light extraction surface is smaller than the average size of the protrusions in a second region.
