Patent ID: 8741398

Claim:
A liquid crystal panel, characterized in that: the liquid crystal panel comprises: a first substrate having a first alignment film; a second substrate having a second alignment film; and a liquid crystal material for filling in a space between the first substrate and the second substrate, wherein the liquid crystal material is in contact with the first alignment film and the second alignment; wherein the first alignment film and the second alignment film are made of a modified polyimide having a structure of conjugated double bond at side chain thereof, and the resistance value of the modified polyimide is less than the resistance value of the liquid crystal material, and the structure of conjugated double bond at the side chain of the modified polyimide has a structural formula (I): wherein n is 1 or an integer greater than 1; and R is H or a carbon chain of C 1 to C 5 ; wherein the first substrate is a thin film transistor (TFT) array substrate, and the second substrate is a color filter substrate.
