DRIVING CIRCUIT FOR ORGANIC EL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a driving circuit for an organic EL element capable of suppressing the variation of ground potential caused by ground wiring resistance, thereby preventing image quality from degrading.

SOLUTION: A common ground line 90 is laid out in two adjacent output stages respectively. Then two adjacent lines of the laid-out ground line are connected respectively by another ground line 91. A similar operation is repeated to connect ground parts of respective output stages finally up to ground terminals 41 and 42.
