摘要： A light control element capable of controlling deflection of light output through a light guide plate to a desired output viewing angle is provided. A light control element (prism sheet) has a plane of incidence on one surface thereof, and a plane of output on the other surface thereof. The plane of incidence is formed as having thereon a number of prism portions arrayed in parallel. Each of the prism portions has a first prism surface allowing incidence of light, and a second prism surface where the light entering through the first prism surface is reflected by total reflection on the inner side. The second prism surface has an outwardly-swelled curved profile, formed with a curvature that allows the light to output through the plane of output at a second output viewing angle wider than a first output viewing angle of a case where the second prism surface is flat.

摘要： A surface illuminating device is provided and includes a plurality of linear light sources, a light-transmissive optical sheet including a luminance-distribution control layer for decreasing unevenness in luminance of light emitted from the linear light sources, and a reflection surface for reflecting the light emitted from the linear light sources. The luminance-distribution control layer includes a plurality of protrusions. In a range of 0≦x≦L/2, protruding directions of some or all the protrusions are inclined such that the protruding directions of the protrusions are located farther from a Z direction, which is an optical axis of a linear light source in an X direction, to the X direction as the protrusions are located farther from the position of x=0 in the X direction, where the X direction represents the arrangement direction of the linear light sources.

摘要： A lens film with small warpage even when a transparent base is thin is provided. Pole prisms made of a hardening resin are arranged along the extending direction on a transparent base made of a flexible material. The transparent base has a depression according to a valley between the pole prisms adjacent to each other. The pole prism has a sloping face extending to an inner wall of the depression. The transparent base is in contact with the valley. A layer not functioning as a prism, that is, a so-called skirt layer does not exist between the transparent base and the pole prisms.
