Abstract
In a method for driving an organic light-emitting display element, the element has a reduced possibility of sticking and a long life without reducing the brightness. In the method for driving a display element having the organic light-emitting element emitting light by a current passing through the organic thin film, a voltage VC applied to the cathode of the organic light-emitting element and a voltage VA applied to the anode of the organic light-emitting element are applied to each surface of the organic thin film through two lines that cross each other. Also, the display of the pixel in the intersection of the two lines is controlled by electric signals through the two lines. During a period of time in which each pixel is unlighted, a recovery voltage within a specified range is applied to the pixel for a specified period of time or longer.
