<p>A circuit for driving a light-emitting panel including a plurality of thin-film transistors arranged for one pixel of a light-emitting element (1) having a matrix construction. The circuit has a transistor offset canceling circuit in which a memory capacitor (C1) is arranged on the input side of the light-emitting element (1), the offset voltage of a drive transistor (M2) is instantly stored in the memory capacitor (C1), and the drop of the offset voltage is compensated when an image signal (Vdata) is applied at the next timing. Therefore, the variation of the transistor characteristics can be canceled to reduce the luminance variation of the light-emitting element and to realize quick response of the light-emitting element.</p> |
