The base includes a front surface and a rear surface facing the front surface. The prism mountains are integrally formed with the base on the rear surface of the base. At least one prism mountain includes a plurality of light incidence surfaces and a reflective surface. The light incidence surfaces receive light. The reflective surface is adjacent to one of the light incidence surfaces to reflect the light. A vertical angle of the prism mountains formed between the light incidence surface adjacent to the reflective surface and the reflective surface, is in a range of about 70° to about 100°.
