An image display apparatus comprises a pixel having a drive transistor and a pixel display element which are connected in series between a first power line and a second power line, a holding capacitor connected to a gate electrode of the drive transistor, and a selection transistor connected between a signal line and the gate electrode of the drive transistor. When the selection transistor is turned on, gradation pixel data is written in the holding capacitor from the signal line. The charge of gradation pixel data written in the holding capacitor is discharged for a certain period through the drive transistor, thereafter the charge of the gradation pixel data stored in the holding capacitor is held by floating the gate electrode of the drive transistor.
