Abstract

A liquid crystal display module, which can prevent corrugations of a reflection plate, and an assembling method thereof are disclosed. The liquid crystal display module comprises: a liquid crystal panel; a light source assembly; a light guide plate; a reflection plate; a support main; and a cover bottom, the reflection plate being disposed to be spaced a predetermined gap from the inner wall surfaces of the support main, the light guide plate being fixed to lateral stepped faces formed on a lateral inner wall surface of the supporter main while maintaining a first gap between the light guide plate and the reflection plate, and the light source assembly being fixed between an inner wall surface of a light incident portion of the support main and an incident surface of the light guide plate while maintaining a second gap between the light source assembly and the reflection plate.

Claims8

Dependent claims

A liquid crystal display module, comprising:

a liquid crystal panel;
a light source assembly for generating a light by a driving power from a light source FPC;
a light guide plate for converting the light into a surface light source to irradiate the same toward the liquid crystal panel;
a reflection plate disposed at the opposite side of the exiting surface of the light guide plate to reflect the light incident to itself toward the light guide plate;
a support main for guiding the light guide plate and the light source assembly using stepped faces formed on inner wall surfaces;
and
a cover bottom disposed to encompass the support main and the bottom surface of one side of the reflection plate,
wherein the reflection plate is disposed to be spaced a predetermined gap from the inner wall surfaces of the support main,
wherein the light guide plate is fixed to lateral stepped faces formed on a lateral inner wall surface of the supporter main while maintaining a first gap between the light guide plate and the reflection plate, and
wherein the light source assembly is fixed between an inner wall surface of a light incident portion of the support main and an incident surface of the light guide plate while maintaining a second gap between the light source assembly and the reflection plate.
