Abstract
The present invention allows light leaked to outside of a light guide plate () from a surface area L to pass through a diffusion sheet () by covering both the bottom of an optical sheet () and the surface area L of the light guide plate () located between an LED FPC () and the optical sheet () with the diffusion sheet (). This irradiates a liquid crystal display panel () with light after the light leaked to outside from the surface area L is diffused by the diffusion sheet (), so unevenness in the brightness of backlight emitted from a backlight device () can be reduced. Thus, the brightness of images displayed on a screen can be made uniform regardless of distance to an LED ().
