摘要 |
A view angle control sheet which can suppress a decrease in screen brightness is provided. Lens portions having trapezoidal shapes in cross section are arranged at predetermined intervals, and a wedge-shaped portion between the lens portions adjacent to each other is filled with the same material as the lens portion or with a material different from the lens portion. In the wedge-shaped portion, a bottom surface is provided on a screen image side while a leading edge is provided on an observer side, and at least a slope portion of the wedge-shaped portion is made of a material having a refractive index lower than that of a lens portion material.
