Abstract:
1. A semiconductor light-emitting device, comprising: a light-emitting structure comprising an active layer capable of emitting light and located between a first type semiconductor layer and a second type semiconductor layer, and a transparent substrate on the first type semiconductor layer, having a first surface and a second surface opposite to the first surface, wherein the first surface is closer to the active layer than the second surface; a transparent carrier located on the second surface of the transparent substrate for carrying the light-emitting structure and distinguishing from the light-emitting structure, having a third surface and a fourth surface opposite to the third surface, wherein the third surface is closer to the active layer than the fourth surface, wherein light emitting from the active layer is capable of escaping from a lateral surface of the transparent carrier; and a reflection layer located on the fourth surface; wherein the light-emitting structure is projected from the transparent carrier, the area of the third surface is not less than each area of the first surface and the second surface and an area ratio of the fourth surface to the active layer is between 4 and 8.
