| titleOfInvention | Retardation film, polarizing plate and liquid crystal display device |
| abstract | The present invention aims to provide a retardation film that is durable to environmental changes and has a small alignment unevenness of the liquid crystal layer, a polarizing plate and a liquid crystal display device using the retardation film, and can be achieved by the following. It was. A retardation film having at least one intermediate layer between a biaxial transparent film and an optically anisotropic layer, wherein the intermediate layer has a rod-like polarizability difference represented by the following formula (1): A planar polarizability represented by the compound having an isotropic of 200 × 10 −25 cm 3 or more and 2000 × 10 −25 cm 3 or less and a distance between terminals of the molecule of 1.5 nm or more and 10 nm or less, or the following formula (2): Contains at least one compound selected from a compound having an anisotropy of 150 × 10 −25 cm 3 or more and 1500 × 10 −25 cm 3 or less and a molecular end-to-end distance of 1.5 nm or more and 10 nm or less. A retardation film characterized by that. Formula (1): Δα = αx− (αy + αz) / 2 Formula (2): Δα = (αx + αy) / 2−αz |
