A display includes: a display section including pixels, and grouping the pixels into pixel groups to assign, in a predetermined assignment pattern, perspective images to the groups, respectively, thereby displaying the perspective images; and a light source device including a light guide plate and one or more first light sources, and emitting light, the light guide plate having a first internal reflection face and a second internal reflection face and having one or more side faces, and the first light sources applying first illumination light into the light guide plate. One or both of the first and second internal reflection faces each have scattering regions arranged in a predetermined arrangement pattern corresponding to the predetermined assignment pattern, the scattering regions allowing the first illumination light from the first light source to be scattered and to exit to the outside of the light guide plate through the first internal reflection face.
