<p>Provided is a low-cost display device which reduces undesired reflection of not only incident outside light from the normal direction but also incident outside light from the oblique direction and has a high contrast ratio and excellent visibility even in a bright room environment. A circularly polarizing plate is provided with a polarizer and a ?/4 plate. The circularly polarizing plate is provided with an antireflective layer, the polarizer, a birefringent layer, and the ?/4 plate which are stacked in this order. The NZ coefficient of the birefringent layer satisfies NZ<0.1, the in-plane fast axis of the birefringent layer is orthogonal to the absorption axis of the polarizer, the NZ coefficient of the ?/4 plate satisfies NZ>0.9, and the in-plane slow axis of the ?/4 plate intersects with the absorption axis of the polarizer.</p> |
