PROBLEM TO BE SOLVED: To provide a display device having a light guide plate of a side-edge light system which is improved in display uniformity.SOLUTION: A light source 2 is arranged on a light incident end face 1a side of a light guide plate 1, and a light source 3 is arranged on a light incident end face 1b side. Light La from the light source 2 irradiates a display pattern DPA of "A" formed at an anti-light emission face 1c of the light guide plate 1, and light Lb from the light source 3 irradiates a display pattern DPB of "B" formed at an anti-light emission face 1c of the light guide plate 1. Clusters C1, C2 composed of linear grooves having a pair of inclined faces (reflection faces) are arranged in a non-overlapped region of the display patterns DPA, DPB, and a cluster C3' composed of a rectangular groove (parallelogram) having two pairs of inclined faces (reflection faces) is arranged in an overlapped region of the display patterns DPA, DPB.SELECTED DRAWING: Figure 1 |
