Abstract
A liquid crystal display device includes a liquid crystal display panel having a liquid crystal layer between a pair of substrates, a light unit arranged in overlapping with the liquid crystal display panel for illuminating the liquid crystal display panel, the light unit including a front case and a back case for housing a light member, and a flexible printed circuit board. The flexible printed circuit board has a folding back portion which is housed at the housing portion provided at the bottom of the case of the backlight unit to adjust its length. The printed circuit board is drawn out from the housing portion to outside and connected to the outer circuits. Accordingly, it is possible to provide a compact and slim type liquid crystal display device.
