Abstract: Transmittance adjustment pattern member including a plurality of patterns is disposed on one face of a substrate and in a light-emitting area and a light-transmissive area such that a distribution density of the patterns in the light-emitting area is higher than a distribution density of the patterns in the light-transmissive area. Accordingly, while light generated in a background area passes through the transmittance adjustment pattern member, light may be first inversely-diffracted such that a wavelength thereof may be converted into an inversely-diffracted wavelet. Then, the light having the inversely-diffracted wavelet passes through the light-transmissive area, and thus the inversely-diffracted wavelet may be eventually converted into a non-diffracted wavelet. Thus, the light having the non-diffracted wavelet proceeds toward the viewing area. Thus, wavelet diffraction caused by the light-transmissive area may be reduced.
