Abstract:
1. A liquid crystal display (LCD) device comprising: a liquid crystal panel; a plurality of lamps under the liquid crystal panel, supplying light to the liquid crystal panel; a diffusion plate above the lamps and diffusing light emitted from the lamps; a reflection sheet below the lamps; a diffusion sheet on the diffusion plate; a plurality of reflection patterns on regions of a rear surface of the diffusion sheet adjacent to the lamps and including reflection beads reflecting a portion of light from the diffusion plate, the plurality of reflection patterns formed in a plurality of groups that correspond to the plurality of lamps with a gap between adjacent groups, the reflection patterns within each group being in direct contact with one another; and a plurality of light collecting patterns on an upper surface of the diffusion sheet to collect a portion of light from the reflection patterns, wherein the light collecting patterns are disposed in a plurality of groups with a gap between adjacent groups of the light collecting patterns, and the light collecting patterns within each group being in direct contact with one another; wherein the respective reflection patterns of the diffusion sheet extend in a direction parallel to a lengthwise direction of the lamps; wherein the reflection beads reflect a portion of light onto the reflection sheet which reflects the portion of light onto regions where the reflection patterns are not disposed on the diffusion sheet; and wherein the reflection beads included in the reflection patterns of the diffusion sheet include a plurality of air balls or contain a reflection terminal coated thereon.
