Abstract

The invention provides a polaroid, a display substrate, a liquid crystal display panel and a making method thereof and belongs to the technical field of display. The problems of poorer orientation effect, lower light transmittance and lower polarization degree of an existing polaroid can be solved. The making method of the polaroid comprises the steps of orientation layer forming and polarization layer forming. The polarization layer forming step comprises the sub-steps that a polarization layer is coated with a mixture, wherein the mixture includes a material capable of performing orientation under the effect of a magnetic field force; orientation is conducted on the mixture through a uniform magnetic field; the mixture is cured to form a polarization layer. The polaroid made by means of the making method has consistent orientation, the light transmittance and lower polarization degree are improved, and the polaroid has better display effect.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a polarizer, a display substrate, a liquid crystal display panel and a preparation method thereof. Background technique [0002] The mainstream of existing display devices is a Liquid Crystal Display (LCD for short). LCD usually uses liquid crystal molecules to cooperate with polarizers to control whether light passes or not, so as to realize image display. [0003] The preparation method of the existing polarizer is as follows: first, coating an alignment layer on a glass substrate; then, coating a mixture forming a polarizing layer on the alignment layer, and the mixture automatically aligns along the grooves on the alignment layer; finally, Curing the mixture forms a polarizing layer. [0004] The inventors have found that the prior art has at least the following problems: the mixture forming the polarizing layer has a low degree of parallelism in the orientatio...
