PROBLEM TO BE SOLVED: To provide a display device including a light guide plate having a dot pattern capable of increasing the illuminance of light emitted from a light emission surface and increasing the illuminance in the light emitted from a light emission end, while suppressing illuminance unevenness in the light emitted from the light emission surface.SOLUTION: The display device includes a light source 21 and a light guide plate 22 which is a light guide plate 22 guiding the light emitted from the light source 21 and includes a light-incident end 221, a light emission end 222, a dot forming surface 223 where a dot pattern D is formed, and a light emission surface 224 reflecting the light from the light source 21 by the dot pattern D and emitting the light. A first displayed member M is irradiated with the light emitted from the light emission surface 224 and a second displayed member E is irradiated with the light emitted from the light emission end 222. In the dot pattern D, the diameter of a dot is increased as it goes to a maximum dot start position S and the diameter of the dot is substantially constant from the maximum dot start position S to the light emission end 222. |
