Manufacture method of liquid crystal display panel

A manufacture method of a liquid crystal display panel, comprising steps of:

• step 1, providing a TFT substrate and a CF substrate, and a first conductive film and a second conductive film are respectively formed on one sides of the TFT substrate and the CF substrate, and both the first conductive film and the second conductive film are graphene/PEDOT:PSS composite transparent conductive films;
• step 2, mixing polar material into liquid crystal material to obtain liquid crystal compound;
• a structural formula of the polar material is A-B, wherein
• A is one or more polar groups connected to B, and the polar group is primary amine, secondary amine, tertiary amine, —OH, —COOH, —SH, —Si(CH3)3 or —CN;
• B is a linear or chain branched alkyl having 5-20 C atoms, and a first group obtained after some CH2 group in the alkyl is replaced by phenyl, cycloalkyl, —O—,—CONH—,—COO—,—O—CO— or —CH═CH— group, a second group obtained after some H atom in the alkyl is replaced by F atom or Cl atom, or a third group obtained after some H atom in the first group is replaced by F atom or Cl atom;
• step 3, employing one drop filling to drop the liquid crystal compound obtained in the step 2 on the one side of the TFT substrate where the first conductive film is or the one side of the CF substrate where the second conductive film is;
• step 4, oppositely vacuum laminating the TFT substrate and the CF substrate to obtain the liquid crystal display panel;
• then, the polar material generates a stronger intermolecular force with the first conductive film on the TFT substrate and the second conductive film on the CF substrate, and is vertically aligned on surfaces of the TFT substrate and the CF substrate, and then liquid crystal molecules in the liquid crystal material are vertically aligned to act a function of liquid crystal alignment;
• wherein a structural formula of the polar material is:
• wherein in the liquid crystal compound obtained in the step 2, a content of the polar material is 0.1˜5 wt %;
• wherein a plurality of roof shape projections are respectively provided on the one sides of the TFT substrate and the CF substrate provided in the step 1 where the first conductive film and the second conductive film are pre-formed.
