Beschreibung
Zusammenfassung:A multilayer film including: a first long-length substrate; and an optically anisotropic layer containing cured liquid crystal molecules, the optically anisotropic layer being directly disposed on a surface of the first substrate, wherein the surface of the first substrate has a surface tension of 35 to 45 mN/m and an orientation-regulation force generated by stretching, and the optically anisotropic layer has a slow axis along approximately the same direction as an orientation direction of the first substrate by the stretching; and an optical compensation sheet, a λ/4 wave plate, a polarizing plate, a circularly polarizing plate, a liquid crystal display device, and an organic electroluminescent display device having the optically anisotropic layer, as well as production methods thereof.
