Abstract
A biaxial liquid crystal composition containing a liquid crystal compound 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.
