Abstract: PROBLEM TO BE SOLVED: To provide a light guide plate capable of suppressing generation of uneven luminance, accompanying when thinning the light guide plate. SOLUTION: This light guide plate 4 includes a light-incident surface 43a, a light-reflecting surface 42, and a light-emitting surface 41. The light-reflecting surface 42 has a plurality of dot patterns 42a and structures 42b. The structure 42b has the height of a projecting and recessed part which is lower than that of the dot pattern 42a and is reticulately spread around the dot pattern 42a. The structure 42b relaxes the difference in the degrees of diffusion, between a position where the dot patterns 42a are formed and a position where the dot patterns are not formed, and reduces the generation of uneven luminance caused by the difference in the degrees of diffusion.
