A reflector is discussed. A reflector can include 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, wherein the first to third reflective layer pairs are formed as a plurality of inorganic layers, the first, second and third reflective layer pair are sequentially stacked iteratively, the first reflective layer pair includes a stop band corresponds to red color wavelength, the second reflective layer pair includes a stop band corresponds to green color wavelength, and the third reflective layer pair includes a stop band corresponds to blue color wavelength.
