Abstract:
1. A liquid crystal cell comprising: a pair of resin substrates; a liquid crystal layer held between the pair of resin substrates, and an optical compensation layer held between one of the pair of the resin substrates and the liquid crystal layer, wherein: the optical compensation layer has a refractive index distribution satisfying nx>ny>nz (nx: a refractive index in a direction (a slow axis direction) in which an in-plane refractive index of the optical compensation layer reaches its maximum, ny: a refractive index in a direction (a fast axis direction) that is orthogonal to the nx direction within a plane of the optical compensation layer, and nz a refractive index in a thickness direction of the optical compensation layer that is orthogonal to each of the nx and ny directions), and the optical compensation layer is formed by applying a material for forming an optical compensation layer to the resin substrate or by applying a material for forming an optical compensation layer to a base substrate that is different from the resin substrate.
