Abstract: The present invention provides a circularly polarizing plate capable of reducing the amount of change in tint and a difference in reflectivity while achieving thinning of a display device and a display device having the same. The circularly polarizing plate of the present invention includes a polarizer, a transparent support, an optically anisotropic layer including a liquid crystal compound in this order, in which the optically anisotropic layer satisfies Expression (1) and the transparent support has a thickness of 50 μm or less and satisfied Expression (2), 100≦Re(550)≦180 nm . . . (1) and 1.00≦R≦1.20 . . . (2), in Expression (1), Re(550) represents an in-plane retardation of the optically anisotropic layer at a wavelength of 550 nm and in Expression (2), R represents a ratio between a maximum value and a minimum value of modulus of elasticity of the transparent support.
