Abstract

A LED module includes a printed circuit board, LEDs which are vertically mounted on the printed circuit board and which emit light onto a side surface, and a contact member which is provided to come into contact with a light guide plate. The printed circuit board may be movably coupled to a bottom chassis. When the light guide plate undergoes thermal expansion, the LED module may move by pressing of the light guide plate acting on the contact member. Accordingly, a gap between the light guide plate and the LEDs may be uniformly maintained even when the light guide plate undergoes thermal expansion or is returned to an original state.

First claim

What is claimed is:

1. A liquid crystal display comprising:
a chassis assembly;
a liquid crystal panel to display an image;
a light guide plate to guide light to the liquid crystal panel;
a LED (light emitting diode) module which is movable relative to the chassis assembly, the LED module comprising a printed circuit board disposed below the light guide plate, a plurality of LEDs mounted on the printed circuit board, and a plurality of contact members provided in the printed…
