The present invention provides a light guide plate including: a lateral surface from which light from a light source enters; a light emission surface from which the light is emitted; and a light reflecting surface reflecting the light. In the light guide plate, at least one of the light emission surface and the light reflecting surface includes: a plurality of first light diffusing portions for diffusing the light, which are formed in either one of a concave and convex shape in a thickness direction of the light guide plate; and a second light diffusing portion that is formed having a uniform surface roughness over an entire surface between a plurality of the first light diffusing portions.
