Title: CIRCULARLY POLARIZING PLATE AND DISPLAY DEVICE
Abstract:
The present invention provides: a circularly polarizing plate that is thin and that can improve the visibility of black color from an oblique direction when applied to a display device; and a display device that includes the circularly polarizing plate. This circularly polarizing plate includes a polarizer, a λ/2 plate, and a λ/4 plate in this order. The λ/2 plate is a multilayer body composed of a first A plate and a first C plate. The λ/4 plate is a multilayer body composed of a second A plate and a second C plate. One of the first C plate and the second C plate is a cellulose acylate film that exhibits a prescribed Rth. The other of the first C plate and the second C plate is an optically anisotropic layer that includes a liquid crystal compound that exhibits a prescribed Rth or is a cellulose acylate film that exhibits a prescribed Rth.
