Abstract:
1. A liquid crystal display device comprising: a first substrate; a second substrate; a liquid crystal layer sandwiched between said first substrate and said second substrate, an orientation status of said liquid crystal layer being a homogeneous orientation when an electric field is not applied thereto; a plurality of color filters having at least three colors formed on a plane located in the vicinity of the liquid crystal layer of said first substrate; a pixel electrode and a common electrode, which are formed on a plane located in the vicinity of the liquid crystal layer of said second substrate; and a plurality of pixels; a liquid crystal layer of each of said pixels is applied an electric field containing a component parallel to a substrate plane by both said pixel electrode and said common electrode and said pixels have a reflection display portion which has a reflection layer and a transmission display portion; wherein: said reflection display portion has a phase difference layer formed over a plane near the liquid crystal layer of the first substrate; and a retardation value of the phase difference layer corresponding to at least two color filters having 2 colors is different from a retardation value of the phase difference layer corresponding to another color filter.
