摘要： A drive device for a light-emitting display panel, having the more extended light-emitting life of an EL element, is provided. Drive switches SX1 to SXn select a reverse direction voltage −V immediately after starting of scanning to supply the voltage −V to all of EL elements in a scanning state. Subsequently, through the switches SX1 to SXn, constant current sources I1 to In are connected to data lines to be controlled for light emitting, and, a forward voltage +V1 (a voltage equal to or smaller than a light-emitting threshold one) is applied to data lines which do not contribute to light emitting. Thereby, the forward voltage is applied to the EL elements in a scanning state.

摘要： An organic EL display apparatus which can improve the reliability thereof, by avoiding a leak current which occurs after an operating time, without reducing the product yield. The organic EL display apparatus is comprised of an organic EL panel section, and a driving section which has a reverse voltage restriction unit (means for restricting a reverse voltage) for restricting a reverse voltage which is applied when organic EL devices are not lighted. When a breakdown voltage with respect to a preset thickness do of the organic material layer has been Vb, the reverse voltage restriction unit will not only set the reverse voltage Vm (to be applied during a non-lighting period) to Vm
