Abstract: A display apparatus includes a light guide member disposed below a display member. A light source configured to generate light is disposed adjacent to the light guide member. The light guide member includes a plurality of diffraction on the light guide member. The diffraction patterns are spaced apart from each other in the first direction. The plurality of diffraction patterns diffract incident light, which is incident at an incident angle, to change the incident light to diffraction light having a diffraction angle. The incident angle is defined as an angle between the incident light and a normal line that is perpendicular to a top surface or a bottom surface of the light guide member. The diffraction angle, which is defined as an angle between the diffraction light and the normal line, has a magnitude less than that of the incident angle.
