Abstract
An active matrix display apparatus comprises plural gate lines and plural source lines that are arranged such that the plural gate lines respectively intersect the plural source lines and light-emitting element circuits, which are provided to respectively correspond to intersections at which the plural gate lines intersect the plural source line. Additionally, each of the light-emitting element circuits includes a light-emitting element for emitting light according to a current supplied thereto, a drive transistor for controlling a current supplied to the light-emitting element, and a control transistor for controlling writing of an image signal to the drive transistor. Furthermore, the drive transistor has a body terminal and is configured to correct luminance of the light-emitting element using a voltage applied to the body terminal.
