Abstract:
A liquid crystal display apparatus comprising:a pair of polarizing plates;a super twisted nematic liquid crystal display device interposed between the polarizing plates;a light diffusing plate for diffusing light having exited from the liquid crystal display device, in a predetermined direction; anda phase difference plate for improving a viewing angle in a direction in which the light is not diffused by the light diffusing plate, the phase difference plate being interposed at least between the polarizing plate on a light exit side and the liquid crystal display device, wherein refractive indices nx, ny and nz of the phase difference plate in three-dimensional direction hold a relationship of nx>nz>ny and an angle between a direction in which the light is diffused by the light diffusing plate and a slow axis of the phase difference plate adjacent to the light diffusing plate is selected to be in a range between 60.degree. and 80.degree..
