Filed: 2007-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a display panel which has the same luminance characteristics to an applied voltage in a transmissive region and a reflective region by compensating the difference in luminance-voltage curve between the transmissive region and reflective region by using simple constitution.  <P>SOLUTION: At a pixel part, a transparent electrode is coupled to a source wiring through a first transistor and a second transistor, and coupled to a reflective electrode through a second transistor. Further, a first end of a pumping capacitor is coupled to the source wiring through the third transistor and a second end is coupled to the reflective electrode. A transmission voltage is applied to the transmissive electrode and the reflective electrode first. Then the reflective electrode and the second end of the pumping capacitor are placed in a floating state and a control voltage is applied to the first end of the pumping capacitor. Electric charges are thereby rearranged between a liquid crystal capacitor in the reflective area and the pumping capacitor, and the voltage of the reflective electrode is adjusted from the transmission voltage to a reflection voltage.  <P>COPYRIGHT: (C)2008,JPO&INPIT
