Reflector and display device having the same

摘要

Discussed are a high efficiency reflector which reflects multiple color light, and a display device which can increase display quality by applying the high efficiency reflector thereto. The reflector includes a first reflective layer pair reflecting red light, a second reflective layer pair reflecting green light, and a third reflective layer pair reflecting blue light. The first to third reflective layer pairs are formed as a plurality of inorganic layers.
