Abstract

A method for forming a liquid crystal alignment layer. First, a first substrate is provided, and a conductive layer, an insulating layer covering the conductive layer, and a plurality of alignment electrodes arranged on the surface of the insulating layer are sequentially formed on the surface of the first substrate. Then a second substrate is arranged parallel to the first substrate, and then a liquid crystal alignment composition and a positive type liquid crystal material are mixed and injected between the first and second substrates, and placed between the conductive layer and the alignment electrode A voltage is applied between the first and second substrates, so that an electric field is generated between the first and second substrates. After the liquid crystal alignment composition is deflected to a predetermined direction, the liquid crystal alignment composition is polymerized to form an alignment layer. Since the arrangement of the conductive layer and the alignment electrodes can make the distribution of the electric field more uniform, the alignment consistency of the liquid crystal alignment composition can be improved.

Description

technical field [0001] The invention relates to a method for forming a liquid crystal alignment layer, in particular to a method for forming a liquid crystal alignment layer that utilizes a uniform electric field to improve molecular alignment. Background technique [0002] In recent years, improving the viewing angle of liquid crystal displays has become an important issue that related companies are eager to solve, especially in-plane switching (IPS) liquid crystal displays and fringe field switching (FFS) ) Liquid crystal display is a common technology at present. The former is designed so that when a voltage is applied, the liquid crystal molecules will rotate on the plane parallel to the substrate; while the latter replaces the metal electrodes of the IPS display with indium tin oxide (ITO) transparent electrodes and shortens the width between the electrodes. . [0003] The known IPS liquid crystal display, as shown in U.S. Patent No. US 5,928,733, mainly has two paral...
