Abstract: Provided is a bendable organic EL display device in which change in tint at a bending portion before and after bending is small. The organic electroluminescent display device is a bendable organic electroluminescent display device including a circularly polarizing plate and a bendable organic EL display panel, in which the circularly polarizing plate includes a polarizer and a retardation layer from a viewing side, the retardation layer includes a first optically anisotropic layer formed by fixing a liquid crystal compound twist-aligned along a helical axis extending in a thickness direction, and the first optically anisotropic layer satisfies a predetermined requirement.
