Abstract: A liquid crystal display panel includes a first polarizer, a second polarizer, a liquid crystal layer including first liquid crystal molecules, a first optical compensation layer between the liquid crystal layer and any of the first polarizer and the second polarizer, a second optical compensation layer on a same side of the liquid crystal layer as the first optical compensation layer. In a non-powered state of the liquid crystal display panel orthographic projections of optical axes of the first liquid crystal molecules on the first polarizer, which are perpendicular to an orthographic projection of an optical axis of the first optical compensation layer on the first polarizer, are parallel to any of transmission axes of the first polarizer and the second polarizer that are perpendicular to each other. An optical axis of the second optical compensation layer is perpendicular to a plane where the second optical compensation layer is located.

Abstract: A liquid crystal composition comprises a photo-polymerizable liquid crystal mixture and a heat-polymerizable liquid crystal mixture, and the two mixtures have opposite rotatory directions. A patterned phase delay film is prepared from the liquid crystal composition. A display device comprises the phase delay film. The preparation of the patterned phase-delay film can be implemented by a two-step polymerization process including UV-polymerization and heat-polymerization. The process is simple and the costs are low.

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.
