Abstract:
An active matrix liquid crystal display comprising:a first substrate; a second substrate; a liquid crystal layer containing dichroic dye and laid between said first and second substrates; said first substrate having a common electrode formed on a closer surface thereof to said liquid crystal layer, and said common electrode having an alignment layer formed thereon; said second substrate having reflective pixel electrodes formed on a closer surface thereof to said liquid crystal layer, a plurality of active elements connected to said reflective pixel electrodes, a phase plate formed among said reflective pixel electrodes and said liquid crystal layer, and an alignment layer formed between said phase plate and said liquid crystal layer; said liquid crystal layer having a twist alignment; and said phase plate having a retardation being set as a half of a retardation between an ordinary ray in incidence in an optical path and an extraordinary ray after reflection by said reflective pixel electrodes in said optical path, and a slow axis being set at about 45 degrees reversely to the twisting direction of said liquid crystal layer from the alignment direction of a closer alignment layer.
