PROBLEM TO BE SOLVED: To provide such a driving circuit for display that makes operational stabilization realizable by stabilizing the potential of a switch that operates according to pixel signals. SOLUTION: This driving circuit is for driving a light emitting display device consisting of light emitting elements such as plural organic light emitting diodes connected to between row and column lines. In this case, each column line CL is connected to a constant current circuit CC that is selectively connected to a constant current source Vd through the first switch S11 opened/closed in accordance with pixel signals, and in addition, it is designed to discharge through the second switch S12 that is opened/closed reverse to the first switch S11. |
