Abstract: A display apparatus includes a light source which generates a first light, a display module which displays an image, a light guide plate disposed under the display module, and an optical filter disposed under the light guide plate to face the display module. The optical filter includes a filter layer which transmits a portion of the first light from the light guide plate and reflects a remaining portion of the first light except for the portion and an absorbing layer disposed under the filter layer to absorb the first light transmitted thereto through the filter layer. As an incident angle of the first light incident to the filter layer with respect to a normal line of an upper surface of the filter layer increases, an overlapping bandwidth between a reflection wavelength bandwidth of the filter layer and a wavelength bandwidth of the first light increases.
