[Paper] Design of Anisotropic Light-diffusing Film for Rotational Use of Reflective Displays

抄録

We examined anisotropic light-diffusing films for reflective displays to realize a wide viewing angle for a rotating screen such as a tablet. By orthogonally laminating 60-μm-thick anisotropic light diffusing films having bent columnar structure, we were able to demonstrate uniform diffuse reflection characteristics for a point light source polar angle of 30° from various azimuth angles. Then, we showed that image blur could be suppressed by narrowing the gap between the reflector and the diffusing layer, such as by grinding the top cell glass.
