Abstract
A liquid-crystal display device is provided which has a backlight that applies light onto a liquid crystal panel. The backlight includes a light guide having an LED as a light-emitting device. The light guide has recesses on the light incident surface, in which electric elements are disposed. Disposing the electric elements connected to external driving circuit in the backlight can reduce the area for mounting the electric elements.
