Abstract
A liquid crystal display panel is described. In an embodiment, the liquid crystal panel display includes: a first linear polarizer; a second linear polarizer; a first quarter-wave plate disposed between a first substrate and the first linear polarizer, an angle between a slow axis of the first quarter-wave plate and an absorption axis of the first linear polarizer being 45° or 135′; a second quarter-wave plate disposed between a liquid crystal layer and the first substrate, slow axes of the first quarter-wave plate and the second quarter-wave plate being perpendicular, and absorption axes of the first linear polarizer and the second linear polarizer being perpendicular; a first retardation film disposed between the first quarter-wave plate and the second quarter-wave plate; and a second retardation film disposed at a side of the first quarter-wave plate facing away from the first retardation film, or disposed between the second linear polarizer and the liquid crystal layer.
