Abstract

PURPOSE: A light guide panel with an intaglio-patterned light reflecting structure is provided to improve the efficiency of light diffusion and the field of view of light guide panel by increasing an internal area of a pattern where the light diffusion generates. CONSTITUTION: A light reflecting structure(10) is formed on a rear of a light guide panel(2). The light reflecting structure(10) is an intaglio pattern formed on the rear of the light guide panel(2) through an intaglio pattern generator. The intaglio pattern includes a semi-circle pattern. A light scattering unit(17) is formed on an internal side of the light reflecting structure(10). The light scattering unit(17) reflects a light incident from a lateral side of the light guide panel(2) to the upper-front direction of the light reflecting structure(10).
