LIGHT DEFLECTION DIFFUSION SHEET, STACKED LIGHT DEFLECTION DIFFUSION SHEET, STACKED OPTICAL SHEET AND LIQUID CRYSTAL DISPLAY USING THE SAME

摘要

A light deflection diffusion sheet, a stacked light deflection diffusion sheet, and a stacked optical sheet used for a liquid crystal display device are disclosed. The liquid crystal display device comprises: a liquid crystal panel having a longitudinal direction and a width direction; a surface light emitting module; a base sheet arranged between the liquid crystal panel and the surface light emitting module; a light diffusion layer formed on a side of the surface light emitting module of the base sheet and configured to diffuse light incident from the surface light emitting module; and a light deflection layer formed on a side of the liquid crystal panel of the base sheet and configured to control a traveling direction of the light. Therefore, the optical sheet reduces an optical loss of the liquid crystal display device.
