A display includes a light guide plate having an incident edge surface and an output surface; a plurality of light sources arranged opposed to the incident edge surface; and a plurality of prisms arranged in a main pattern on a surface, each prism having a reflective surface configured to reflect light from any of the plurality of light sources towards the output surface. A curvature of the reflective surface of a first prism arranged in a first sub-pattern of the main pattern, is different from a curvature of the reflective surface of a second prism arranged in a second sub-pattern of the main pattern.
