<P>PROBLEM TO BE SOLVED: To reduce a leakage current of a basic drive element connected to a switching transistor. <P>SOLUTION: The characteristics related to current drive capabilities of a first switching transistor Tr1 and a second switching transistor Tr2, serially connected between a data line 16 and the gate electrode of a third transistor Tr3 for driving a diode 12 are differentiated from each other. By increasing the holding characteristic of either the first transistor Tr1 or the second transistor Tr2, as well as increasing the current drive capability of the other transistor, the two serially connected transistors reduce the leakage current. <P>COPYRIGHT: (C)2003,JPO |
