    摘要: A liquid crystal display includes a lower substrate and an upper substrate facing each other, a liquid crystal layer disposed between the lower substrate and the upper substrate, a color conversion layer disposed on the liquid crystal layer, a first polarizing layer and a first phase difference layer disposed between the liquid crystal layer and the color conversion layer, and a second polarizing layer and a second phase difference layer disposed between a light source and the lower substrate, wherein the first phase difference layer has a refractive index satisfying Inequality 1 and the second phase difference layer has refractive indexes satisfying Inequality 2. nx1≥ny1≥nz1  [Inequality 1] nx2>nz2>ny2  [Inequality 2] In Inequalities 1 and 2, nx1, nx2, ny1, ny2, nz1, and nz2 are the same in the detailed description.

    摘要: A compensation film includes a first retardation layer including a polymer having negative birefringence, and a second retardation layer including a liquid crystal having positive birefringence, where the first retardation layer has an in-plane retardation (Re1) of 320 nm to 1050 nm for incident light having wavelength of 550 nm, the second retardation layer has an in-plane retardation (Re2) of 180 nm to 910 nm for the incident light, an entire in-plane retardation (Re0) of the first and second retardation layers for the incident light is a difference between the in-plane retardations of the first and second retardation layers, an angle between slow axes of the first and second retardation layers is 85 to 95 degrees, and the entire in-plane retardation (Re0) of the first and second retardation layers for the wavelength of 450 nm, 550 nm and 650 nm satisfies Re0 (450 nm)
