Abstract: A pixel and its process for an in-plane switching liquid crystal display achieves more spreading angles and smooth performance for scattering of light for image display therewith by using a reflector having a reflective surface with roughness in nanometer scale for light scattering and contrast improvement. As a result, the reflectivity doesn't change enormously with the viewing angle and excellent anti-glare effect is obtained. Moreover, the roughness of the reflective surface is formed by the crystallization and the characteristic of the material thereof owns, and thus no additional mask is required.

Abstract: A thin-film transistor and a liquid crystal display having an ultra minimal rough reflective layer on pixel design are described. An ultra minimal rough reflective layer with an ultra minimal rough surface is formed on a substrate. The ultra minimal rough reflective layer includes an amorphous or partial crystalline indium tin oxide layer and a silicon-containing rugged layer to form the ultra minimal rough surface. A reflective layer conformal to the rugged layer is then formed thereon to obtain an ultra minimal roughness reflective surface, thereby to enhance reflective results.

Abstract: A storage capacitor having a scattering effect is positioned in a substrate for use in a thin film transistor array loop. The storage capacitor is characterized by having a rough layer overlapped by a medium layer and a passivation layer. The storage capacitor further has a reflective layer with high reflectivity so as to provide the storage capacitor with the scattering effect toward an external light source. A method of manufacturing the storage capacitor by two photolithography processes is also shown.
