摘要：
A diffuser includes a first substrate and a gel layer. The first substrate has a first refractive index n1. The gel layer includes a body and at least one microstructure. The body is disposed on the first substrate. The microstructure is disposed on the body, wherein the dimension of the microstructure is smaller than that of the body. The body is located between the microstructure and the first substrate. The gel layer has a second refractive index n2, and n1>n2.
