摘要： A planar light source includes a backlight that emits light in a planar shape, a ray direction regulating element that regulates a direction of light made incident from the backlight and emits the light, whereby a directivity of the light is improved, and in which a transparent area for transmitting light and an absorption area for absorbing light are formed, and a transparent and scattering switching element that is switchable between a state in which light which is transmitted by the ray direction regulating element and made incident on the switching element is transmitted and a state in which the light is scattered. The transparent areas are formed in a shape of a matrix including a plurality of rows and a plurality of columns, the transparent and absorption areas are formed alternately, and the absorption area is formed so that the transparent areas are separated.
