Abstract
A reflective liquid crystal display such as an AMLCD includes an array of reflective pixels located over a surface of a silicon substrate, with light transmissive regions being located between the reflective pixels. The structure includes two metal layers between the reflective pixels and the silicon substrate surface, with segments of one metal layer extending in a first direction to form row electrodes of the LCD and segments of the other metal layer extending in a second direction substantially perpendicular to the first to form column electrodes of the LCD. In order to block light that would otherwise pass through light transmissive regions between the reflective pixels, portions of the first two metal layers extend beneath the light transmissive regions between the reflective pixels. In this manner, a light-blocking function is provided without the need for a separate blocking or shading metal layer.
