Kind Code:
A1
Abstract:
The present invention relates to a light guide panel, a manufacturing method therefor, a backlight unit including the same, and a liquid crystal display including the same. More particularly, the present invention relates to a light guide panel, a manufacturing method therefor, a backlight unit including the same, and a liquid crystal display including the same, wherein the light guide panel comprises divided optical patterns on the front side thereof such that shielding properties of the optical patterns can be increased when an optical sheet is stacked while the light guide panel is mounted on a backlight unit, light from a light source can be uniformly emitted to the front side, and pitches or the size or the like of the optical patterns can be changed, thereby easily adjusting an emission angle and exhibiting exterior adjusting performance.
