Abstract
A light guide panel (LGP) for use in a liquid crystal display (LCD) apparatus includes a light-emitting pattern surface on which light-emitting patterns are formed, an opposite surface opposite to the light-emitting pattern surface, and four edge surfaces. Lenticular patterns are formed on one of the light-emitting pattern surface and the opposite surface. The light-emitting pattern surface includes a light-emitting part in which the light-emitting patterns are formed; and an edge part which extends along the four edge surfaces to enclose the light-emitting part and in which at least one fixing groove is formed to fix the LGP. The light-emitting part includes a pattern reducing region which faces the fixing groove and has a lower light-emitting pattern density than an other region of the light-emitting part.
