Abstract
In order to improve processing steps of fabricating an active-matrix addressed reflective liquid crystal display, a lower substrate, which is positioned at one side with respect to a liquid crystal layer, is provided with two electrodes in parallel with each other and in parallel with the liquid crystal layer. One of the two electrodes is electrically coupled to a source electrode of a switching element assigned to one pixel, and the other electrode is electrically couple to a constant potential source. Each of the two electrodes has characteristics of light reflectivity, which is able to reduce the intensity of exposing light when an insulating layer provided above the electrodes is patterned.
