Disclosed is a liquid crystal display module having a reduced thickness
thereof. A light exit surface of a light guiding plate for converting a
linear light source output from the lamp in the form of planar light
source is non-planarized with a plurality of convex portions having a
desired height. A prism sheet for controlling a path of the light output
from the light guiding plate is laid on the light guiding plate, as being
opposite the plurality of convex portions. Accordingly, it is possible to
uniformly control the brightness distribution of the light output from
the light guiding plate without providing a separate diffusing plate
between the light guiding plate and the prism sheet. In addition, since
the plurality of convex portions which are formed integrally with the
light guiding plate directly faces the prism sheet, adherence between the
light guiding plate and the prism sheet can be prevented. Therefore, the
diffusing plate can be eliminated from the liquid crystal display module,
thereby reducing the number of components, and thus minimizing the
thickness of the liquid crystal display module.
