Thereafter, during a data write period in which the first scan signal GW_i of a low level is received, the scan transistor T2 and the compensation transistor T3 are turned on, and the data voltage Dm_j is received by the source S of the driving transistor T1. By the compensation transistor T3, the driving transistor T1 is diode-connected, and biased in a forward direction. A gate voltage of the driving transistor T1 rises from the first initialization voltage VINT1. When the gate voltage of the driving transistor T1 is equal to a data compensation voltage (Dm_j?|Vth|) obtained by subtracting the data voltage Dm_j by a threshold voltage Vth of the driving transistor T1, the driving transistor T1 is turned off, and the gate voltage of the driving transistor T1 stops rising. Thus, a voltage difference (ELVDD?Dm_j+|Vth|) between the first driving voltage ELVDD and the data compensation voltage (Dm_j?|Vth|) is stored in the storage capacitor Cst.
In addition, during an anode initialization period in which the third scan signal GB_i of a low level is received, the anode initialization transistor T7 is turned on, and the second initialization voltage VINT2 is applied to the anode of the light-emitting element OLED. By applying the second initialization voltage VINT2 to the anode of the light-emitting element OLED to completely stop the light-emitting element OLED from emitting light, a phenomenon in which the light-emitting element OLED emits fine light in response to the black grayscale in the next frame may be eliminated.
