Abstract: In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

Abstract: 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.
