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.
