Abstract

A liquid crystal display panel includes a first and second base substrates, a liquid crystal layer and an optical compensation layer. In the liquid crystal layer, a first alignment film is configured to make a part of second liquid crystal molecules proximate to the first alignment film have a first pretilt angle, a second alignment film is configured to make a part of second liquid crystal molecules proximate to the second alignment film have a second pretilt angle. In the optical compensation layer, a third alignment film is configured to make first liquid crystal molecules proximate to the third alignment film have a third pretilt angle. A direction of orthogonal projections of long axes of the first liquid crystal molecules is parallel to or perpendicular to a direction of orthogonal projections of long axes of second liquid crystal molecules anchored by the first alignment film and the second alignment film.
