  • Semitransmissive liquid crystal display device and manufacturing method thereof
    Publication number: 20050219451
    Abstract: The present invention intends to provide a manufacturing method of a semi-transmissive liquid crystal display device in which method a structure and manufacturing process thereof are simplified to enable to reduce the manufacturing cost. In order to achieve the above object, a semi-transmissive liquid crystal display device in the invention has a layer constitution in which a reflective pixel electrode is formed with a second conductive film that constitutes a source electrode, a drain electrode, a source wiring and so on and on an upper layer of the second metal film a transmissive pixel electrode made of a transparent conductive film is formed through the insulating film. A TFT array substrate can be formed through 5 times of photoengraving process.
