Abstract
A liquid crystal display has a driving substrate on which transparent pixel electrodes are formed; a counter substrate on which a counter electrode is formed; and a liquid crystal material disposed between the driving and counter substrates. Liquid crystal material molecules are oriented orthogonally to the substrates. The driving substrate has pixel capacitors and pixel transistors formed thereon, with the pixel capacitors disposed under the pixel electrodes. The pixel transistors act to write signal voltages to the pixel electrodes and pixel capacitors. The pixel electrodes have slits formed over the pixel capacitors to orient the the liquid crystal material molecules orthogonally and in a split manner. Each of the pixel capacitors has an electrode for reflecting light and forms a reflective region. Liquid crystal material portions in the reflective regions have a thickness greater than half the thickness of liquid crystal material portions in other transmissive regions.
