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 anchor a part, proximate to the first alignment film, of second liquid crystal molecules, and a second alignment film is configured to anchor a part, proximate to the second alignment film, of the second liquid crystal molecules. In the optical compensation layer, a third alignment film is configured to anchor first liquid crystal molecules proximate to the third alignment film. A direction of orthogonal projections of long axes of the first liquid crystal molecules is parallel to a direction of orthogonal projections of long axes of second liquid crystal molecules anchored by the first and second alignment films. Rubbing directions of the first alignment film, the second alignment film and the third alignment film are the same.
