Abstract
A light emission surface having a substantially single surface in a liquid crystal display is designed so as to be opposite to a rear of a liquid crystal panel or a rear of an optical member through an air layer. Thus, it is possible to provide a liquid crystal display that can prevent a heat accumulation in a liquid crystal panel without any drop of brightness, and a light source device used in the liquid crystal display.
