Abstract
Provided is a liquid crystal display apparatus. The liquid crystal display apparatus includes: a first substrate; a second substrate facing the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a first liquid crystal alignment layer disposed between the first substrate and the liquid crystal layer; and a second liquid crystal alignment layer disposed between the second substrate and the liquid crystal layer. The first liquid crystal alignment layer may include a first ion adsorbing group, and the second liquid crystal alignment layer may include a second ion adsorbing group. A content of the first ion adsorbing group in the first liquid crystal alignment layer may be different from that of the second ion adsorbing group in the second liquid crystal alignment layer, or a chemical structure of the first ion adsorbing group may be different from that of the second ion adsorbing group.
