ABSTRACT:
A liquid crystal display device includes a first substrate and a second substrate with a liquid crystal material sandwiched therebetween, a pixel having an optically transmissive portion and an optically reflective portion, a phase plate which is formed between the second substrate and the liquid crystal material in the optically transmissive portion of the pixel, and a color filter which is formed between the second substrate and the liquid crystal material in the optically transmissive portion of the pixel and between the phase plate and the liquid crystal material in the optically reflective portion of the pixel. A counter electrode is formed between the color filter and the liquid crystal material, and a pixel electrode is formed between the first substrate and the liquid crystal material. An electric field which is produced by a voltage between the pixel electrode and the counter electrode induces behavior of the liquid crystal material.
