Claim:
1. A liquid crystal display comprising, in sequence: a first polarizer; a liquid crystal cell including a liquid crystal layer containing liquid crystal molecules horizontally aligned to a face of a substrate of the liquid crystal cell; and a second polarizer; the liquid crystal display further comprising a first optical compensation film disposed between the first polarizer and the liquid crystal cell or between the liquid crystal cell and the second polarizer, an absorption axis of the first polarizer, an optical axis of the first optical compensation film, and an optical axis of the liquid crystal layer of the liquid crystal cell being parallel to each other in a view of the liquid crystal cell in a direction orthogonal to the face of the substrate of the liquid crystal cell, the optical axis of the liquid crystal layer of the liquid crystal cell and the optical axis of the first optical compensation film having a tilt angle from the face of the substrate of the liquid crystal cell in a same direction, and the first optical compensation film having positive birefringence; the liquid crystal display further comprising: a second optical compensation film in the second polarizer at the side of the liquid crystal cell, wherein the second optical compensation film satisfies: where |Re( 550 )| represents an absolute value of the in-plane retardation at a wavelength of 550 nm, and wherein the second optical compensation film satisfies: where Re( 550 ) represents in-plane retardation (nm) at a wavelength of 550 nm, and Rth( 550 ) represents retardation (nm) across the thickness at a wavelength of 550 nm.
