OPTICAL FILM AND IMAGE DISPLAY UNIT |
摘要 |
<p>An optical film comprising a scattering-dichroic absorption composite polarizer consisting of a film having a structure in which fine areas are dispersed in a matrix formed by translucent resin containing an iodine absorption element, and a double refracting film that is a transparent film formed by solid polymer and satisfies characteristics, nx>ny>nz, when a direction in which an in-phase refractive index is maximum is an X-axis, a direction perpendicular to the X-axis a Y-axis, and a film thickness direction a Z-axis, and refractive indexes in respective axis directions are respectively nx, ny, and nz. Such an optical film has a high contrast over a wide viewing angle, and a high transmittance and a high polarization degree to be able to limit non-uniformity in transmittance at black displaying.</p> |
