MOTHER SUBSTRATE, LIGHT-CONTROL MEMBER, METHOD FOR MANUFACTURING LIGHT-CONTROL MEMBER, AND DISPLAY DEVICE
Abstract:
A light-control member (13) includes a substrate (39); light-shielding layers (40) provided in a first area (A1) on one surface (39a) of the substrate (39); a light-diffusion section (41) provided in an area other than the light-shielding layers (40) in the first area (A1) and formed of light transmitting material; and a support section(45) provided in a second area (A2) positioned on an outer side of the first area (A1) on the one surface (39a), in which the light-diffusion section (41) has a light emitting end surface (41a) in contact with the one surface (39a) of the substrate (39), a light incident end surface (41b) opposing the light emitting end surface (41a) and having an area greater than an area of the light emitting end surface (41a), and a reflective surface (41c) which is in contact with the light emitting end surface (41a) and the light incident end surface (41b) and on which light incident from the light incident end surface (41b) is reflected, and a formation area of the support section (45) per unit area in the second area (A2) is greater than a formation area of the support section (45) per unit area in the first area (A1).
Abstract(Chinese):

光控构件（13）包括衬底（39）; 设置在基板（39）的一个表面（39a）上的第一区域（A1）中的遮光层（40）; 设置在所述第一区域（A1）中的除了所述遮光层（40）以外的区域并由透光材料形成的光扩散部（41） 以及设置在位于所述一个表面（39a）上的所述第一区域（A1）的外侧的第二区域（A2）中的支撑部（45），所述光扩散部（41）具有发光端 与基板（39）的一个表面（39a）接触的表面（41a），与发光端面（41a）相对的面积大于发光端面积的光入射端面（41b） 以及与发光端面（41a）和光入射端面（41b）接触并且从光入射端面（41b）入射的光被反射的反射面（41a）和反射面（41c） 并且第二区域（A2）中每单位面积的支撑部分（45）的形成面积大于第一区域（A1）中每单位面积的支撑部分（45）的形成面积。
