Abstract: Optical elements of a light guide plate are formed by repeatedly aligning convex parts in a longitudinal direction of the optical elements. Concave/convex shaped parts whose recess amount and/or protrusion amount are not constant are formed by three-dimensional curved surfaces that constitute the convex parts. An optical path of light that enters from an incident light surface of the light guide plate is modified by the concave/convex shaped parts that constitute the optical elements as the light progresses through the inside of the light guide plate, and thereby the light is diffused. Further, since the recess amount and/or protrusion amount of the concave/convex shaped parts are not constant, the optical path of light progressing through the inside of the light guide plate is modified randomly, and therefore a light diffusing effect is efficiently exhibited.
