Photosensitive monomer, liquid crystal panel and manufacturing method thereof

Abstract

The invention discloses a photosensitive monomer which is a compound III, wherein m is no less than 1, L is hydrogen atom, fluorine atom, chlorine atom, cyano, alkyl, alkylcarbonyl, carbalkoxy or alkylcarbonyloxy with 1-7 carbon atoms; R is hydrogen atom, fluorine atom, chlorine atom, cyano, thiocyano, sulfur pentafluoride group, nitrite radical, linear or branched alkyl with 1-12 carbon atoms or Z2-Sp2-P2 group; Z1 and Z2 are respectively oxygen atom, sulfur atom, methoxy, carbonyl, carboxyl, carbamoyl, methylthio, ethylene carbonyl, carbonyl vinyl or single bond; and Sp1 and Sp2 are linear or branched alkyl with 1-8 carbon atoms or single bond.

Description

This application is a divisional application of Chinese patent application 200710006219.2 (application date: February 7, 2007, invention name: photosensitive monomer, liquid crystal panel and its manufacturing method). technical field The invention relates to a photosensitive monomer, and in particular to a photosensitive monomer applied to a liquid crystal panel and a manufacturing method thereof. Background technique In recent years, liquid crystal panels have developed an alignment technology: Polymer-Stabilizing Alignment (PSA) technology, which is to mix photosensitive monomers into the liquid crystal layer, and then irradiate ultraviolet light after they are arranged to make the photosensitive The monomers are polymerized into alignment polymers to guide the arrangement of liquid crystal molecules. In order to shorten the polymerization time, a photosensitive monomer and a photoinitiator (initiator) are mixed in the liquid crystal layer at the same time to help the ...
