PROBLEM TO BE SOLVED: To provide a display device provided with a light guide plate capable of emitting uniform planar light without forming a lenticular lens array.SOLUTION: The display device comprises: a light source (120); and a light guide plate (150) in which light from the light source is incident from a light incident surface serving as one of side surfaces and exits from a light exiting surface serving as a surface perpendicular to the light incident surface. In a reflection surface serving as a surface facing the light exiting surface, the light guide plate serves as an outer convex part extending in parallel with the light incident surface and is provided with a plurality of V shape grooves (152) in which a cross-sectional shape in the light incident surface and surface perpendicular to the reflection surface is formed into the V shape, and in the reflection surface, the light guide plate is further provided with a plurality of dot grooves (151) which serves as the outer convex part with a curve edge. In the reflection surface, a dot groove region (161) in which the plurality of dot grooves is only formed is disposed closer to a light incident surface side than a V shape groove region (162). |
