Patent ID: 7656477

Claim:
A reflective display device comprising: a light modulating layer; two substrates, between which the light modulating layer is interposed; and an electrode structure that changes the optical properties of the light modulating layer on a pixel-by-pixel basis, wherein one of the two substrates includes a corner cube array in which a plurality of corner cubes are arranged, and wherein the corner cube array includes a principal surface that defines a retroreflective surface, a bottom and a plurality of conductive members that are arranged between the principal surface and the bottom, and wherein a portion of the upper surface of each said conductive member defines a part of the principal surface of the corner cube array, the part being located in a lowest-level portion of its associated corner cube including the lowest-level point thereof, and wherein the conductive member is in electrical communication with a drain electrode of a TFT and with the principal surface which comprises a reflective layer, and wherein another portion of the conductive member which is spaced apart from the lowest-level portion of the associated corner cube is covered by an insulating film that is provided between the conductive member and the principal surface of the corner cube array.
