<p>To provide a light source unit or a display capable of preventing optical sheets from being erroneously assembled. Step faces (213, 214, 215, 223, 224, 225) are provided in optical sheet support members (21, 22), and the outer edges of the optical sheets (15a) are positioned by the step faces (213, 214, 215, 223, 224, 225). Thereby, the optical sheets (15a)(concretely, a diffusion plate (151), a first diffusion sheet (152), a second diffusion sheet (153), a third diffusion sheet (154)) are so disposed as to be overlapped with each other and displaced from each other in the direction of the step faces, and at least parts of the outer edges of the optical sheets (15a) are disposed at positions where they do not coincide with each other.</p> |
