OPTICAL LAMINATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

[Problem] Conventional polarizing films are obtained by bonding transparent protective films on both surfaces of polarizers that have a thickness of about 30 µm. The conventional polarizing films show a dimensional change of about -0.5% in an environment test at 80°C for 120 hours. Consequently, the conventional polarizing films are at risk of suffering from the occurrence of moire fringes, color unevenness or blurring of three-dimensional display. [Solution] An optical laminate (10) wherein a polarizing film (13), which is obtained by laminating a thin polarizing film (12) on one main surface of a base (11), and an optical element (a lens array (14)) are laminated. The thin polarizing film (12) has a thickness of 8 µm or less. The base (11) has a thickness of 20-80 µm. Alternatively, the optical element is a patterned retardation plate (114) which is provided with a plurality of regions that have different slow axis directions.
