A light guide plate including a diffusion pattern is provided to perpendicularly reflect light toward a light emitting side of a light guide plate by forming a plurality of V-shaped cutting grooves as diffusion patterns, separating the plurality of diffusion patterns, and forming a light incident surface and a surface adjacent to the light incident surface at a predetermined angle with respect to a bottom surface. Diffusion patterns(40) are formed such that a plurality of grooves are consecutively disposed. The diffusion patterns are spaced apart from each other at a set interval. A light incident surface of a groove closest to a light source of the plurality of grooves of the diffusion patterns is inclined at a predetermined angle with respect to a bottom surface so as to perpendicularly reflect light toward a light emitting surface(32). |
