LIGHT-DIFFUSING MEMBER, METHOD FOR MANUFACTURING THE SAME, AND DISPLAY DEVICE

摘要

A method for manufacturing a light-diffusing member includes a process of forming a light shielding layer on one surface of a substrate (30); a process of forming a negative photosensitive resin layer on the one surface of the substrate (30) so as to cover the light shielding layer; a process of exposing the negative photosensitive resin layer by irradiating the negative photosensitive resin layer with parallel light of ultraviolet light diagonally with respect to a normal direction of the one surface of the substrate (30) from a surface opposite to the one surface of the substrate (30) on which the light shielding layer and the negative photosensitive resin layer are formed in at least one direction through a region of the substrate (30) other than a region where the light shielding layer is formed; and a process of forming a light-diffusing section, which includes a light emission end surface on a side close to the substrate (30) and a light incident end surface having an area greater than an area of the light emission end surface on a side opposite to the substrate (30), on the one surface of the substrate (30) by developing the exposed negative photosensitive resin layer.

1. A method for manufacturing a light-diffusing member, the method comprising:
a process of forming a light shielding layer on one surface of a substrate having light transparency; a process of forming a negative photosensitive resin layer having light transparency on the one surface of the substrate so as to cover the light shielding layer; a process of exposing the negative photosensitive resin layer by irradiating the negative photosensitive resin layer with parallel light of ultraviolet light diagonally with respect to a normal direction of the one surface of the substrate from a surface opposite to the one surface of the substrate on which the light shielding layer and the negative photosensitive resin layer are formed in at least one direction through a region of the substrate other than a region where the light shielding layer is formed; and a process of forming a light-diffusing section, which includes a light emission end surface on a side close to the substrate and a light incident end surface having an area greater than an area of the light emission end surface on a side opposite to the substrate, on the one surface of the substrate by developing the exposed negative photosensitive resin layer.
