Abstract
There is provided a light distribution control panel that can suppress reflection on a glass surface in a mobile unit when the light distribution control panel is applied to a display device mounted on the mobile unit, and a display device for mounting on a mobile unit in which the light distribution control panel is used. A light distribution control panel includes a base body serving as a plate-like or sheet-like base material made of a translucent material, and the base body has a plurality of convex portions for light distribution control formed on one surface opposite to the backlight side of the base body. The plurality of convex portions are positioned to extend in parallel to one another. The light distribution control panel includes a light transmission/reflection suppressing portion (a surface of one side surface having higher roughness than that of a surface of the other side surface) for suppressing emission, from at least a part (one side surface) of a surface of the convex portion, of light incident from a surface of the base body on the light source side.
