摘要:
A liquid crystal display device includes a first substrate having one surface on which a first electrode is provided, a second substrate which is provided with a second electrode, and a liquid crystal layer which is interposed between the first and second substrates. Negative dielectric anisotropy homeotropic aligning films are formed on mutually faced surfaces of the first and second electrodes, respectively. A pair of polarizing plates are arranged on a side of the other surface opposite to the one surface of each substrate. A pair of optical compensation layers are arranged respectively between the other surfaces of the substrates and the polarizing plates, and give a retardation having a value which is substantially ¼ of a wavelength λ of transmitted visible light to the transmitted visible light.
