Abstract
Provided is a varnish composition which can achieve well-balanced electrical characteristics such as a residual charge, a voltage-holding ratio and image sticking and various characteristics such as a pretilt angle, a coating property and an aligning property, which are desired to a liquid crystal alignment film which is prepared therefrom. The above varnish composition comprises a polymer component comprising a polyamide acid represented by Formula (1), a polyamide represented by Formula (2) or the polyamide represented by Formula (2) and a soluble polyimide represented by Formula (3), and a solvent, wherein the above polymer component contains 1 to 60% by weight of the polyamide represented by Formula (2), and the above varnish composition contains 0.1 to 40% by weight of the polymer component:
