Alignment composition, liquid crystal display panel and method of manufacturing same
Abstract:
An alignment composition is presented that includes an alignment polymer and a reactive mesogen. The alignment polymer includes a polyimide backbone and a vertical alignment side chain combined with the polyimide backbone. The reactive mesogen may be represented by the formula M5-M1-M2-M3-M4 in which M1 represents a divalent organic group including an aromatic ring group, M2 represents M3 represents a single bond, —O—, —O—(CH2)a—O—, or —(CH2)a—O—, wherein “a” represents an integer of 1 to 20, M4 represents an alkenyl group or an alkynyl group having a carbon number of 2 to 20 an alkenylcarbonyl group having a carbon number of 3 to 20, an alkenylcarbonyloxy group having a carbon number of 3 to 20, a an oxotetrahydrofuryl group having —(C═CH2)— substituted for at least one —CH2—, or an epoxy group. M5 represents -M2-M3-M4 or -M3-M4.
