Patent ID: 7643113

Claim:
A transflective liquid crystal display device in which a transmissive area to transmit light from a backlight to a pixel area and a reflective area to reflect externally incident ambient light as well as a thin film transistor to drive liquid crystal are arranged on an insulating substrate, comprising: an TFT array substrate which includes: a plurality of gate wirings each provided with a gate electrode made of a first conductive film which is formed on the insulating substrate; a storage capacitive wiring provided with a storage capacitive electrode made of the first conductive film; a plurality of source wirings each provided with a source electrode made of a second conductive film which crosses the gate wirings and is formed on the first conductive film through a first insulating film; a drain electrode made of the second conductive film a reflecting pixel electrode made of the second conductive film and extending from the drain electrode to form the reflective area, the drain electrode and the reflecting pixel electrode being formed in the same layer and electrically connected to each other; a transmissive pixel electrode forming the transmissive area which is formed on the second conductive film through a second insulating film; and an opposite substrate which is arranged oppositely to the TFT array substrate; wherein the source wirings and the reflecting pixel electrode are arranged apart from each other by a predetermined interval, and the storage capacitive electrode extends from a portion below the reflecting pixel electrode to a portion below the interval; and a contrast reduction preventing electrode is formed over the interval on the second insulating film, and at least a part of the contrast reduction preventing electrode being located above the storage capacitive electrode.
