<P>PROBLEM TO BE SOLVED: To provide a pixel circuit capable of preventing quality degradation of a display image by making the amount of a flowing current constant even when an organic EL element 1130 is deteriorated. <P>SOLUTION: The pixel circuit 110 is provided with a capacitative element 1120 which accumulates charge in accordance with current flowing through a data line 104 when a scanning line 102 is selected, a TFT 1102 which allows the current I<SB>2</SB>in accordance with the accumulated charge to flow between source and drain after the selection, the organic EL element 1130 of which the anode is connected with the drain side of the TFT 1102, the TFT 1112 which detects an applied voltage to the organic EL element 1130 and allows the current I<SB>3</SB>in accordance with the accumulated charge to flow between source and drain and a correction circuit 1110 which generates a Miller current I<SB>4</SB>of the current I<SB>3</SB>and adds the same to the current I<SB>2</SB>. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
