Optical film, and lighting device and image viewing display using the same |
| abstract |
At least one cholesteric liquid crystal layer (1) and a retardation layer (2) are laminated, wherein in-plane retardation of the retardation layer (2): (nx 1 -ny 1 ) × Dre is 5 or less, and the direction phase difference of the imaginary thickness: RZch and thickness direction retardation: RZre can be used as the brightness enhancement film with an optical film having a relation of RZre / (-RZch) = 0.05 to 0.35, and in an oblique direction as well as in a front direction in an image display device such as a liquid crystal display. It also provides excellent visibility satisfaction even when observed. |
