The invention relates to a compensation membrane, compensation membrane producing method and liquid crystal display panel using the compensation membrane. The producing method of compensation membrane comprises: forming an optical membrane on the surface of the substrate; forming distribution membrane by defining multi-track groove on the surface of the optical membrane; forming a liquid crystal layer on the surface of the distribution membrane, the liquid crystal molecule in the liquid crystal layer is defined to preset slant angle by multi-track groove of the distribution membrane and the slant angle of the liquid crystal molecule in each layer changes along with the change of distance between the substrates; solidifying the liquid crystal layer; defining compensation membrane with multi layer structure by repeating the above steps. The compensation membrane can effectively reduce the light leaking of the liquid crystal display panel using the said compensation membrane and increase the contrast, at the same time increase the wide visual angle of the liquid crystal display panel using the said compensation membrane.
Description
technical field [0001] The invention relates to a compensation film and a manufacturing method thereof, in particular to a liquid crystal display panel using the compensation film. Background technique [0002] Generally, when the liquid crystal molecules of a normally white mode twisted nematic liquid crystal display panel (TN-LCD) are applied with an external voltage, their long axis is easily affected by the electric field generated by the voltage, and tends to be parallel to the electric field and to the direction of the liquid crystal display panel. The alignment films in the liquid crystal layer are aligned in a vertical state. However, the liquid crystal molecules located at the upper and lower edges of the liquid crystal layer of the liquid crystal display panel cannot be completely perpendicular to the alignment film due to the anchoring force generated by the alignment film. In practice, when an external electric field affects the liquid crystal layer of the liqui...
