Abstract
Provided is a display device including: a light guide plate arranged so that an edge surface thereof is opposed to a light source, the light guide plate being configured to internally reflect light entering from the edge surface to cause planar light emission from a front surface of the light guide plate; and a reflective sheet arranged so as to be opposed to a rear surface of the light guide plate. Irregularities are formed on the front surface. The irregularities are formed to have a shape of a combination of first convex portions and second convex portions, each of the first convex portions including a first ridge line which continuously extends along a first direction corresponding to a light traveling direction, each of the second convex portions including a second ridge line which continuously extends along a second direction intersecting the first direction.
