MOTHER SUBSTRATE, LIGHT-CONTROL MEMBER, METHOD FOR MANUFACTURING LIGHT-CONTROL MEMBER, AND DISPLAY DEVICE

摘要

A light-control member (13) is provided with a substrate (39), a light-blocking layer (40) disposed in a first area (A1) on one surface (39a) of the substrate (39), a light-diffusing part (41) composed of a light-transmitting material disposed in areas other than the light-blocking layer (40) of the first area (A1), and a support part (45) disposed in a second area (A2) positioned outside the first area (A1) on the one surface (39a). The light-diffusing part (41) has a light-emitting end face (41a) in contact with the one surface (39a) of the substrate (39), a light-incident end face (41b) having a surface area that is greater with respect to the light-emitting end face (41a) than the surface area of the light-emitting end face (41a), and a reflecting surface (41c) for reflecting light that is incident from the light-incident end face (41b), the reflecting surface (41c) being in contact with the light-emitting end face (41a) and the light-incident end face (41b). The formation surface area of the support part (45) per unit surface area in the second area (A2) is greater than the formation surface area of the support part (45) per unit surface area in the first area (A1).
