摘要：
A light source is provided including, 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 and in which a transparent area for transmitting light and an absorption area for absorbing light are formed alternately in a direction perpendicular to a light regulating direction thereof, and a transparent and scattering switching element that is capable of switching a state in which light made incident from the ray direction regulating element is transmitted and a state in which the light is scattered.
