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

摘要

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).

主权项

1: A mother substrate, comprising:
a first substrate having light transmissivity and including a light-control member formation area; light-shielding layers provided in a first area in the light-control member formation area; a plurality of light-diffusion sections provided in an area other than the light-shielding layers in the first area and formed of light transmitting material; and the light transmitting material provided in a second area positioned on an outer side of the first area in the light-control member formation area, wherein each of the light-diffusion sections has a light emitting end surface positioned at one end of a first surface side of the first substrate, a light incident end surface opposing the light emitting end surface and having an area greater than an area of the light emitting end surface, and a reflective surface which is in contact with the light emitting end surface and the light incident end surface and on which light incident from the light incident end surface is reflected, and a formation area of the light transmitting material per unit area in the second area is greater than a formation area of the light transmitting material per unit area in the first area.
