Optical film, circular polarizing plate, and organic electroluminescence display device |
| abstract |
The present invention provides: an optical film that is thin, is suitable for continuous production, and suppresses color tinting of black color in a front direction and a diagonal direction when used as a circular polarizing plate in an organic EL display device; a circular polarizing plate; and an organic EL display device. The optical film of the present invention has a long support, a first optical anisotropic layer, a second optical anisotropic layer, and a third optical anisotropic layer in this order, wherein: the thickness of the long support is 10-45 μm; the first optical anisotropic layer is a layer formed by using a rod-shaped liquid crystal compound; the second optical anisotropic layer is a layer formed by fixing a twist-aligned liquid crystal compound having a spiral axis in a thickness direction; the third optical anisotropic layer is a layer formed by using a liquid crystal compound; and the optical anisotropic layers each exhibit predetermined optical characteristics. |
