Abstract
Herein disclosed an image display including: row scan lines configured to supply a control signal; column signal lines configured to supply a video signal; and pixel circuits configured to be disposed at intersections between the scan lines and the signal lines, wherein each of the pixel circuits has at least a drive transistor, a sampling transistor connected to a gate of the drive transistor, a capacitive part connected between the gate and a source of the drive transistor, and a light-emitting element connected to the source of the drive transistor.
