Patent ID: 7057697

Claim:
A pixel for an in-plane switching liquid crystal display, comprising: a first structure on a substrate having a reflective surface with a nanometer scale roughness defined by a height in the range of 5–50 nm and a width less than 20 nm for enhancing a light scattering angle and contrast enhancement, the first structure including (a) a micro scattering layer on the substrate with the nanometer scale roughness, the micro scattering layer being formed by a conductor on the substrate and an insulator on the conductor with the nanometer scale roughness and (b) a reflective layer made of high reflective metal on the micro scattering layer and conformal to the micro scattering layer to thereby form the reflective surface; a second structure on a first part of the first structure having a switch device thereof; a liquid crystal layer above the second structure and a second part of the first structure; and a third structure on the liquid crystal layer.
