<P>PROBLEM TO BE SOLVED: To solve a problem that a leak current is increased by light under illumination to change a gradation current flowing in an organic EL element, whereby a black level rises and contrast is lowered in a transistor arranged in the pixel of an organic EL display device. <P>SOLUTION: The gate terminal and the drain terminal of a driving transistor 202 for driving the organic EL element 201 are connected through a diode 223 to reduce the leak current. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
