A light guide panel is provided to improve the uniformity, and brightness by narrowing the pitch of V-shaped grooves as it goes from a light incident part to a light opposite part on a reflective surface. A plurality of dot patterns are formed at the first region(I) close to light sources on a reflective surface(102). A plurality of first V-shaped grooves(110) are formed to extend in the first direction and a plurality of second V-shaped grooves(120) are formed to extend in the second direction at the second region(II) connected with the first region(I). The first and second V-shaped grooves(110,120) are arranged to cross each other. The first region(I) is about 2 percent to 4 percent of the entire region of the reflective surface(102). The diameter of a dot is 40 micrometer to 50 micrometer. |
