Provided is a liquid crystal display device including a first substrate on which a first alignment layer is formed, a second substrate on which a second alignment layer is formed, and a liquid crystal layer disposed between the first and second alignment layers and including liquid crystals of a helical structure in which a helical axis is parallel to the first and second substrates.

The present application discloses a display panel, a method of photo alignment and a driving method of the display panel. A display area of the display panel is divided into at least a first area and a second area, light transmittance of the first area is different from that of the second area when driven by the identical voltage difference, and pre-tilt angles of liquid crystal molecules corresponding to the first area are different from those of liquid crystal molecules corresponding to the second area.

A liquid crystal display includes: a first substrate; a pixel electrode disposed on the first substrate; a second substrate facing the first substrate; a common electrode disposed on the second substrate; and a liquid crystal layer disposed between the first substrate and the second substrate.

A transflective LCD device and a method of forming the same are proposed. The transflective LCD includes a first substrate, a second substrate, a first alignment film, a second alignment film and a liquid crystal layer. The first substrate and the second substrate are divided into a transmissive area and a reflective area, in which areas of the first alignment film and the second alignment film are configured respectively by different aligning angles. The liquid crystal molecules in the liquid crystal layer corresponding to the transmissive area and the reflective area are tilted by different pretilt angles. Therefore, light going one-way through the liquid crystal layer corresponding to the transmissive area generates the same phase retardation as making a round-trip through the liquid crystal layer corresponding to the reflective area. The present invention can simplify technical difficulties, and reduce occurrences of poor rubbing and dark-state light leakage.

A liquid crystal panel includes a first four-domain structure, a second four-domain structure, a third four-domain structure, and a fourth four-domain structure repeatedly arranged.

A pretilt angle of the rotated liquid crystal within the first four-domain structure is different from the second, and the pretilt angle of the rotated liquid crystal within the third four-domain structure is different from the fourth. With such configuration, the light leakage and color shift issue may be eliminated.
