摘要： A phase-type diffraction device includes a substrate having a front surface and a solidified liquid crystal layer formed on the front surface of the substrate and constituted by a continuous film containing at least a liquid crystal compound. The solidified liquid crystal layer is constituted by first, second and third regions arranged periodically, the third region being interposed between the first region and the second region. The first region is optically anisotropic and the second region is optically isotropic, the third region is not optically isotropic, a degree of orientation of mesogens of the liquid crystal compound being lower than that of the first region. An in-plane average refractive index ni of the second region is different from an in-plane average refractive index na of the first region and an in-plane average refractive index nm of the third region is between ni and na.
