Abstract:
1. A liquid crystal display device, comprising: first and second substrates that face each other; a liquid crystal layer interposed between the first and second substrates; a thin film transistor (TFT) formed on the first substrate; and a pixel electrode electrically connected with the TFT and including a reflective portion having a reflective electrode and a transmissive portion having a transmissive electrode, and the reflective portion and the transmissive portion of the pixel electrode have a same cell gap, wherein the reflective electrode is formed of an opaque conductive polymer material and the transmissive electrode is formed of a transparent conductive material, wherein the reflective electrode and the transmissive electrode of the pixel electrode are electrically connected together, and wherein the opaque conductive polymer material of the reflective electrode includes a polyimide with a metal doped thereon or a mixture of a transition metal complex including a polyimide and a transition metal ligand.
