Branched organosilicon material, and method for manufacturing liquid crystal display panels

A method for manufacturing a liquid crystal display panel, comprising:

• step 1):
• providing a cell body including a first substrate and a second substrate, neither the first substrate nor the second substrate having an alignment film;
• step 2):
• adding a reactive monomer and a branched organosilicon material into a liquid crystal to obtain a mixed solution;
• step 3):
• dropwise adding the mixed solution between the first substrate and the second substrate in the cell body, at which time the branched organosilicon material enables the liquid crystal to be vertically aligned on a surface of the first substrate and a surface of the second substrate;
• step 4):
• applying a voltage to deflect the liquid crystal, followed by polymerization of the reactive monomer on the surface of the first substrate and the surface of the second substrate, to anchor the liquid crystal;
• and
• step 5):
• releasing the voltage to obtain the liquid crystal display panel,
• wherein the branched organosilicon material has a molecular formula shown in formula I,
• SinO2n+1R1nR2n+2, formula I
• wherein R1 is directly connected to a silicon atom, while R2 is connected to a silicon atom via an oxygen atom, two adjacent silicon atoms being connected via an oxygen atom;
• wherein n is an integer in the range from 2 to 15;
• wherein R2 is a C1-C5 alkyl;
• and
• wherein R1 is a group containing 10-30 carbon atoms, including at least one group selected from —CR3═CR3—, —C≡C—, C6-C20 arylene, C3-C15 cycloalkylene, —CONH—, and —COO—, one or more H atoms of R1 being substituted by heteroatoms, wherein R3 is hydrogen or a C1-C3 alkyl.
