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.

Display device

A display apparatus includes: a display panel, a backlight unit on a rear surface of the display panel, the backlight unit including: a light source unit including a plurality of light sources overlapping a display area of the display panel, an optical layer on the rear surface of the display panel, and a diffusion layer between the light source unit and the optical layer, the diffusion layer being configured to diffuse light emitted from the plurality of light sources, and a vibration generating device configured to vibrate the backlight unit.
