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.

Abstract: A backlight unit and a display apparatus are provided. The backlight unit including light emitting elements disposed in parallel with each other along a rear side of a display panel; and light guide blocks. Each of the light blocks has a shape of a conical hat and respectively corresponds to one of the light emitting elements. Each of the light guide blocks also includes an accommodation part accommodating the light emitting element such that light radiated from the light emitting element is incident to the light guide block; a slope part extending at an angle from an edge of the bottom side of the guide block toward the display panel and refracting light spread in the light guide block to transmit the light to the display panel; and a pattern part having a patterned shape so as to reflect light spread in the light guide block toward the slope part.
