LIGHT GUIDE PALTE AND BACK LIGHT UMIT USING THE SAME

摘要

PURPOSE: A light guide plate and a backlight unit including the same are provided to increase optical brightness by increasing the depth of an optical pattern of a brightness degradation portion and increasing arrangement density. CONSTITUTION: A light source is mounted on a printed circuit board. An optical plate comprises one side and the other side facing the one side. The optical plate additionally comprises a light source receiving groove. The optical plate guides light. A plurality of optical patterns(p1-pn) is formed at one side of the optical plate as an intaglio structure. The more the plurality of optical patterns is far from the light source, the more the depth of the plurality of optical patterns becomes deeper.
