Abstract
An optical assembly, a liquid crystal display panel, and a display apparatus, the optical assembly including: a quarter-wave plate, a half-wave plate, and a linear polariser stacked in sequence; the direction of the absorption axis of the linear polariser, the direction of the slow axis of the half-wave plate and the quarter-wave plate are all parallel to the linear polariser; a first included angle between the direction of the absorption axis of the linear polariser and a first direction is 90°-100°; a second included angle between the direction of the slow axis of the half-wave plate and the first direction is 107°-114°; a third included angle between the direction of the slow axis of the quarter-wave plate and the first direction is 164°-176°.
