    摘要： An image display device includes pixel circuits, a power supply line, and a data line for supplying a data signal to the pixel circuits. The pixel circuits each include a light emitting element, a drive transistor for controlling light emission of the light emitting element, a storage capacitor provided between the data line and a gate electrode of the drive transistor, a both-end connection switch for connecting both ends of the storage capacitor to each other, and a current interruption switch for interrupting a path of a current flowing from the power supply line through the both-end connection switch. Before the data signal is supplied to each of the pixel circuits, the both-end connection switch connects the both ends of the storage capacitor to each other, and the current interruption switch is disconnected.

Only power source lines Lv of sub pixels B and a bypass line Lb are connected with each other in a first row (X1), only power source lines Lv of sub pixels R and a bypass line Lb are connected with each other in a second row (X2), and only power source lines Lv of sub pixels G and a bypass line Lb are connected with each other in a third row (X3). Then, these arrangements of the sub pixels B, R, G, the power source lines Lv and the bypass lines Lb are repeated.
