Patent ID: 8416374

Claim:
A liquid crystal display having a pixel region with a plurality of pixels capable of displaying an image including a plurality of reflection portions for display by ambient light introduced from the outside and a plurality of transmission portions for display by light from an internal light source, wherein a reflectance of the light by the reflection portion of a selected pixel is 1 percent to 30 percent of the light incident thereon, for defining an entire display signal range from a lowest value to highest value and a transmittance of light by the transmission portion of a selected pixel is at most from 5 percent to 10 percent of the light incident thereon, for defining an entire display signal range from a lowest value to highest value, and further wherein the reflection electrode is formed exclusively in an interconnect region such that it is substantially centered over a conductor extending along the side of the pixel at which the reflection electrode is located and the reflection electrode has a center line average roughness of less than or equal to 0.02 micrometers and further wherein the reflection region is exclusively located above a Cs line interconnect region with an opening in the color filter being centered directly over the Cs line interconnect while maintaining the specified reflectance and transmittance characteristics.
