Abstract: A light-diffusion member (7) includes: a substrate (39) having light-transmitting properties; a light-diffusion portion (40) on a face of the substrate (39) facing a display medium (6); and a light-blocking layer (41) on a part of the face of the substrate (39) facing the display medium (6) other than where the light-diffusion portion (40) is provided. The light-diffusion portion (40) includes: a light-emitting end face (40a) in contact with the substrate (39); and a light-incident end face (40b) facing, and being larger in area than, the light-emitting end face (40a). The adhesive layer (42) adheres to light-incident end face (40a) and partly (42a) encroaches into a space (43) between the light-diffusion portion (40) and light-blocking layer (41).
