Liquid crystal display device
First Claim
1. A liquid crystal display device comprising a liquid crystal cell that comprises a pair of substrates disposed to face each other and having an electrode on one side thereof, and a liquid crystal layer sandwiched between the substrates and containing a nematic liquid crystal material aligned nearly in parallel to the surfaces of the pair of substrates at the time of no voltage application thereto, and two polarizing plates disposed on both outer sides of the liquid crystal cell, wherein at least one of the polarizing plates comprises a polarizer and a protective film disposed on at least one surface of the polarizer, and an optically anisotropic layer is disposed between the liquid crystal cell and the polarizer provided that the optically anisotropic layer and one of the protective films may be the same, and the optically anisotropic layer comprises a hybrid-aligned compound, and the alignment control direction of the hybrid-aligned compound is nearly in parallel to absorption axis of any one of the polarizers provided in the liquid crystal display device.

Abstract
A liquid crystal display device comprising a liquid crystal cell containing a nematic liquid crystal material aligned nearly in parallel to the surfaces of the cell at the time of no voltage application thereto, and two polarizers disposed on both outer sides of the liquid crystal cell, wherein the optically anisotropic layer comprising a hybrid-aligned compound is disposed between the liquid crystal cell and one of the polarizers and the alignment control direction of the hybrid-aligned compound is nearly in parallel to absorption axis of any one of the polarizers.
