Abstract

Disclosed are a thermal crosslink material, a manufacture method of a liquid crystal display panel, and a liquid crystal display panel. A structural formula of the thermal crosslink material is

wherein A is

B is

and R is a linear or chain branched alkyl having 5-20 C atoms, wherein one or more CH 2 in the alkyl is substituted with phenyl, cycloalkyl, —O—, —CONH—, —COO—, —O—CO—, —CO—, or —CH═CH— group, or one or more H atoms in the first group are substituted with F atom or Cl atom; a specific crosslink material may be one of

Molecules of the thermal crosslink material crosslink together to form a polymer having a crosslinked network, and groups A and B can be anchored on a substrate surface. The branch R provides an effect of vertical alignment and can form alignment films.

First claim

What is claimed is:

1. A liquid crystal display panel, comprising:
a thin film transistor (TFT) substrate and a color filter (CF) substrate which are arranged opposite to each other;
a liquid crystal layer sandwiched between the TFT substrate and the CF substrate;
a sealant sealing the TFT substrate and the CF substrate; and
alignment films disposed on surfaces of the TFT substrate and the CF substrate facing the liquid crystal layer;
wherein a plurality of triangular shape projections are provided on sides of the TFT substrate and the CF substrate facing the liquid crystal layer;
the liquid crystal layer comprises a liquid crystal material;
the alignment films are made of a polymer, which is formed by mixing a thermal crosslink material represented by

in the liquid crystal material to generate a crosslinking reaction in a heating condition, so as to form a liquid crystal composition and depositing the liquid crystal composition on the surfaces of the TFT substrate and the CF substrate, where
A is

B is

and
R is a linear or chain branched alkyl having 5 to 20 carbon atoms, wherein one or more CH 2 group in the alkyl is substituted with phenyl, cycloalkyl, —O—, —CONH—, —COO—, —O—CO—, —CO—, or —CH═CH— group, or one or more hydrogen atoms in the alkyl or substituted alkyl are substituted with F atom or Cl atom; and
wherein a structural formula of the thermal crosslink material is:
