<P>PROBLEM TO BE SOLVED: To provide a two-screen display device which has a simple configuration, high definition, and low power consumption. <P>SOLUTION: A pixel circuit 20 includes: a first light emitting element E1 provided between a first power line 16a and a node NB; a second light emitting element E2 provided between a second power line 16b and the node NB; and a driving transistor TrB provided between a third power line 18 and the node NB. In an initialization period, a potential of the third power line 18 is set lower than those of the first power line 16a and the second power line 16b. In a write period, potentials of the first power line 16a, the second power line 16b, and the third power line 18 are set equal to each other and then a data potential VD[j] is supplied to a gate of the driving transistor TrB. In a first light emission period, a potential is supplied to the first power line 16a so as to exceed a light emission threshold voltage of the first light emitting element E1. In a second light emission period, a potential is supplied to the second power line 16b so as to exceed a light emission threshold voltage of the second light emitting element E2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
