Abstract
The liquid crystal display device of the present invention comprises a liquid crystal display panel 1, a heat sink substrate 5 acting as the outer frame, and the back light (BL) equipped with a light guide plate 3 and a LED light source array arranged on an assembly substrate 21. There are provided heat conducting members 20, 31, 32, 34 between the assembly substrate 21 and the heat sink substrate, thereby reducing the heat accumulation in the assembly substrate and suppressing temperature increase in the LED light source.
