<P>PROBLEM TO BE SOLVED: To realize a reasonable level of a specified current and to provide a display device having a high definition. <P>SOLUTION: Pixels P<SB>i,j</SB>in an organic EL display 1 are arranged in a matrix, and the pixels P<SB>i,j</SB>are provided with organic EL elements E<SB>i,j</SB>and pixel circuits D<SB>i,j</SB>. Voltage of level according to a specified sync current level which flows to signal line Y<SB>j</SB>in selection period is held to a transistor 23, and a transport electric current of which level follows the voltage level of the transistor 23 is made flow through to an organic EL device E<SB>i,j</SB>in a non-selection period. Further, a current mirror circuit M<SB>j</SB>makes the sync current of which level is proportional to the level of a gradation signal inputted from a data driver 3 flow in the signal line Y<SB>j</SB>. Further, the level of the sync current is made smaller than the level of the gradation signal by the current mirror circuit M<SB>j</SB>. <P>COPYRIGHT: (C)2004,JPO |
