Abstract
A light emitting device includes a light emitting device on a substrate; an encapsulation layer covering the light emitting device; and a texture layer on the encapsulation layer. A surface of the texture layer has a ridge structure. A radial cross section of the ridge structure has a triangular shape with a distal vertex relative to the encapsulation layer surface. The distal vertex has one or more altitude angles, and the one or more altitude angles are less than or equal to 40 degrees.
