摘要：
A retardation compensation element (32, 32a) has a first optical anisotropic layer (42) that functions as a negative C-plate, and a second and a third optical anisotropic layers (43, 44) that function as positive O-plates. VA mode liquid crystal molecules (37) tilt at an azimuth angle of 45 degrees and a polar angle of 5 degrees when no voltage is applied thereto. The second and third optical anisotropic layers have optical axes respectively at an angle of -105 degrees and +105 degrees from the tilt direction of the liquid crystal molecule. The first optical anisotropic layer (42) compensates the retardation of light that enters a liquid crystal layer (38) at an oblique angle while the second and third optical anisotropic layers (43, 44) compensate the retardation of light that enters the liquid crystal layer at a right angle.
