Patent ID: 8228467

Claim:
A reflective color filter LCD, in a reverse order of receiving an incident light along an incident direction, comprising: a backplane substrate, a reflective electrode layer, a planar liquid crystal cell, a transparent conductive film and a transparent plate, wherein: the transparent plate is adapted for receiving and transmitting the incident light; the planar liquid crystal cell is sandwiched between the reflective electrode layer and the transparent conductive film; the reflective electrode layer comprises a first band reflective electrode, a second band reflective electrode and a third band reflective electrode placed on top of the backplane substrate in a regularly tiled planar arrangement perpendicular to the incident direction, and are electrically isolated from each other by a first alignment layer, adapted for reflecting the incident light passing through the transparent plate to form a first reflective light corresponding to a first reflection spectrum, a second reflective light corresponding to a second reflection spectrum and a third reflective light corresponding to a third reflection spectrum, respectively; the backplane substrate comprises a driving circuitry electrically connected to the first band reflective electrode, the second band reflective electrode and the third band reflective electrode, adapted for forming electric field between the reflective electrode layer and the transparent conductive film, driving liquid crystal molecules in the planar liquid crystal cell to twist so as to allow the incident light to reach the reflective electrode layer and allow the first reflective light, the second reflective light and the third reflective light to irradiate out of the transparent substrate, wherein the first alignment layer is coated above the reflective electrode layer, and further filled in gaps among the first band reflective electrode, the second band reflective electrode and the third band reflective electrode to electrically isolate the first band reflective electrode, the second band reflective electrode and the third band reflective electrode from each other.
