The present disclosure is directed to a liquid crystal display device including a display panel having a red pixel, a green pixel, and a blue pixel; and a backlight unit configured to emit light to the display panel. The backlight unit includes a light source which outputs a first color light; a color conversion layer configured to convert the first color light into a second color light such that red light and green light are spatially separated; and an optical sheet which diffuses or condenses the second color light.

Backlight unit and liquid crystal display device including the same

The present disclosure is directed to a liquid crystal display device including a display panel having a red pixel, a green pixel, and a blue pixel; and a backlight unit which emits light to the display panel. The backlight unit includes a light source which outputs a first color light; a color conversion layer which is disposed on the light source and converts the first color light into a second color light; an optical sheet which diffuses or condenses the second color light; and an air gap formed between the color conversion layer and the optical sheet.

A liquid crystal display (LCD) device includes: a liquid crystal panel; a plurality of lamps disposed under the liquid crystal panel, supplying light to the liquid crystal panel; a diffusion plate disposed above the lamps and diffusing light emitted from the lamps; a diffusion sheet disposed on the diffusion plate and including a plurality of reflection patterns formed on a region of a rear surface adjacent to the lamps and including reflection beads reflecting a portion of light from the diffusion plate, wherein the respective reflection patterns of the diffusion sheet are formed to extend in a direction parallel to a lengthwise direction of the lamps.
