Claim Text:
1. A light-diffusing member having a polarizing plate, comprising: a light-diffusing member including a light-transmissive substrate, a plurality of light-shielding layers which are formed on one surface of the substrate, and a light-diffusing section that is formed in regions on the one surface of the substrate other than regions in which the light-shielding layers are formed; and a polarizing plate that is disposed on a side opposite to a substrate side of the light-diffusing member, wherein the light-diffusing member is configured to diffuse light, which is incident from a polarizing plate side, in an anisotropic manner in an azimuth angle direction viewed from a normal direction of the substrate, the light-diffusing section has a light-emitting end surface that is in contact with the substrate, a light-incident end surface that is opposite to the light-emitting end surface and has an area larger than an area of the light-emitting end surface, and a reflective surface that is in contact with the light-emitting end surface and the light-incident end surface and reflects light incident from the light-incident end surface, a height of the light-diffusing section from the light-incident end surface to the light-emitting end surface is set to be larger than a layer thickness of the light-shielding layers, and an azimuth angle direction in which diffusibility of the light-diffusing member is relatively strong, and a transmission axis of the polarizing plate are approximately parallel with each other.
