Zusammenfassung:An EL display device 1 includes a display portion 2 having unit pixels 10 arranged in a matrix, a source line driver circuit 6 , and a gate line driver circuit 4 . Each of the unit pixels 10 has an EL element 11 , a switching transistor Tr 1 , a driver transistor Tr 2 , and an auxiliary capacitor 13 . The auxiliary capacitor 13 has electrodes, one connected to a gate electrode of the transistor Tr 2 and the other to a next gate line GL. The gate line driver circuit 4 outputs, via the next gate line GL, blanking signals for forcibly stopping a light-emitting state of the EL elements 11 , within hold times in which the voltages written to the gate electrodes of the transistors Tr 2 are held. With such a configuration, a blanking period where the EL elements do not emit light, is inserted in one frame.
