<P>PROBLEM TO BE SOLVED: To provide an organic EL display device in which luminance irregularity on a screen is reduced, rate of integration is made high and which is particularly suitable for high luminance color display. <P>SOLUTION: An organic EL drive circuit comprises a first current mirror circuit provided in a drive stage of a current drive circuit having an input stage for generating a reference current and an output stage for current-driving terminals of an organic EL display panel and having n output side transistors connected in current mirror relation to an input side drive transistor, for driving said output stage, where n is an integer equal to or larger than 30 and a drive current regulator circuit for regulating drive current of said input side drive transistor. The input side drive transistor is arranged in a center portion of an arrangement of the n output side transistors and an output current of the output stage is regulated by the drive current regulator circuit. <P>COPYRIGHT: (C)2003,JPO |
