LIGHT-DIFFUSING POLARIZATION PLATE AND LIQUID-CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a new light-diffusing polarization plate that diffuses light sufficiently and also provides other good optical functionality. Also disclosed is a liquid-crystal display device (400) using said light-diffusing polarization plate. The light-diffusing polarization plate (100) is provided with: a polarizing film (101); a light-diffusing film (102) laminated onto the polarizing film (101); and a surface-treated film (103) laminated onto the light-diffusing film (102). The light-diffusing film (102) has a light-diffusing layer (106) that contains: a light-transmitting resin (106a); and between 20 and 100 weight parts of light-transmitting microparticles (106b), dispersed in the light-transmitting resin (106a), per 100 weight parts of the light-transmitting resin (106a). The surface-treated film (103) is formed from a transparent resin film (107), one surface of which is optically treated. The light-diffusion layer (106) and the surface-treated film (103) are bonded to each other by an adhesive or pressure-sensitive adhesive layer (104).
