Abstract:
1. A liquid crystal display comprising: a first substrate having a common electrode formed thereon; a second substrate opposed to said first substrate and having a plurality of pixel electrodes formed thereon and having a plurality of thin film transistors corresponding to each of said pixel electrodes; a liquid crystal layer disposed between said first and second substrates; wherein each of said pixel electrodes has a smaller area than that of said common electrode, and is approximately covered by said common electrode; wherein each of said pixel electrodes has a shape made of a link of a plurality of sub-pixels made of electrode portions each having approximately symmetrical shape; in said plurality of sub-pixels, there exist a plurality of minute areas having different directions of rising up of liquid crystal molecules, and electrode of each of said sub-pixels has a smaller area than that of said common electrode, and is approximately covered by said common electrode; wherein an electrode portion of at least one of said sub-pixels has high reflectance; wherein said liquid crystal layer comprises liquid crystal material having negative anisotropy of permittivity, and liquid crystal molecules of said liquid crystal material align approximately perpendicular to the surfaces of said first and second substrates when no voltage is applied thereto; and wherein said second substrate has an area lacking an electrode, said area being adjacent to said pixel electrode, with said area being opposite said thin film transistor across said pixel electrode.
