Title:
LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL ALIGNMENT METHOD THEREFOR, AND LIQUID CRYSTAL DISPLAY
Document Type and Number:
WIPO Patent Application WO/2018/094865
Kind Code:
A1
Abstract:
A liquid crystal panel, comprising a colour film substrate (100) and an array substrate (200, 200') arranged in an aligned manner, and a plurality of liquid crystal molecules (300) sandwiched between the colour film substrate (100) and the array substrate (200, 200'), wherein the colour film substrate (100) comprises an alignment electrode (150) and a first alignment film layer (160) arranged on the alignment electrode (150), and the array substrate (200, 200') comprises a common electrode (270) and a second alignment film layer (280) arranged on the common electrode (270); when the liquid crystal molecules (300) are aligned, mechanical friction processing is performed on the first alignment film layer (160) and the second alignment film layer (280), and then, voltages are applied to the alignment electrode (150) and the common electrode (270); and ultraviolet exposure is performed on the liquid crystal molecules (300) so as to provide a vertical electric field between the colour film substrate (100) and the array substrate (200, 200') so that the pre-tilt angle of the liquid crystal molecules (300) reaches 0°. By means of a liquid crystal alignment method for the liquid crystal panel, the pre-tilt angle of the liquid crystal molecules (300) can reach 0°, thereby preventing IPS-type and FFS-type liquid crystal panels from leaking light when in a dark state.
