Abstract
An active type display panel comprises a plurality of pixel sections each having a series circuit constituted by a light emitting element and a drive element for supplying a drive current to the light emitting element, a pair of power supply lines which connect the series circuits of the pixel sections in parallel, and a plurality of measurement lines. Each of the pixel sections includes a switch element between a point connecting the light emitting element and the drive element, and one line of the measurement lines. A display device, in which the display panel is used, detects the voltage across the terminals of the light emitting element and controls the drive element such that the voltage across these terminals is a predetermined voltage.
