Abstract:
1. A liquid crystal display device comprising: a first substrate and a second substrate disposed opposite to each other 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 reflective portion of the pixel; 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 which is formed between the color filter and the liquid crystal material; and a pixel electrode which is formed between the first substrate and the liquid crystal material; wherein a protrusive film is formed over the phase plate and has a width in a plane of the protrusive film which is greater than a width of the phase plate in a plane thereof.
