Abstract:
A liquid crystal display includes a pair of substrates including at least one transparent substrate, a liquid crystal layer arranged between the substrates, a plurality of electrodes formed on at least one of the substrates to apply an electric field to the liquid crystal layer, a plurality of active elements connected to the electrodes, an alignment layer formed on the surface of each of the substrates in contact with the liquid crystal layer, and an optical means formed on at least one of the substrates to change the optical characteristics in accordance with the alignment condition of the particles of the liquid crystal layer. The taper angle at the ends of the electrodes is larger than 45 degrees but less than 90 degrees.
