Provided is a liquid crystal display apparatus capable of avoiding heat radiation hindrance caused from blocking of a heat radiation path by electric wiring and from interference of the electric wiring with a radiating portion for heat generated from circuit boards, in which a heat diffusion member and the circuit boards including an LED driver substrate are arranged in a plane at the rear of a frame in a housing while being isolated from one another, and LED light sources mounted on metal blocks are connected to the LED substrate through a flexible cable which is led from the outsides of the metal blocks and the heat diffusion member and is then led between the heat diffusion member and a rear case.
