Abstract: A novel aromatic diamine compound, a poly(amic acid) using the compound, a light alignment layer using the poly(amic acid), and a liquid crystal cell containing the light alignment layer are provided to improve heat resistance, transparency, surface hardness and voltage holding ratio and to reduce surface roughness. An aromatic diamine compound is represented by the formula 1, wherein a is an integer of 1-10; b is an integer of 0-10; A is a group represented by the formula A if b is an integer of 1-10; R1, R2, R3, R4 and R5 are independently a C1-C10 alkyl substituted or unsubstituted with a halogen atom, a cyano group, a nitro group, a carboxyl acid group or an aminocarbonyl group; and A is a group represented by the formula B if b is 0.
