Abstract:
1. A biaxial liquid crystal composition comprising at least one liquid crystal compound which develops a liquid crystal phase whose refractive indexes in directions of three axes are different from each other and a refractive index-controlling agent, which is capable of developing a biaxial liquid crystal phase, and has a value of (nx−ny)/(ny−nz) and a value of (nx0−ny0)/(ny0−nz0) different from each other wherein nx, ny and nz respectively represent refractive indexes along directions of three axes of the biaxial liquid crystal composition in an order of magnitude, and nx0, ny0 and nz0 respectively represent refractive indexes along directions of three axes of the biaxial composition obtained by excluding the refractive index-controlling agent from the biaxial liquid crystal composition in an order of magnitude.
