Abstract
In each pixel, a current-driven type light emitting element OLED, and a driving element Twhich controls an electric current to be supplied to the light emitting element in accordance with a data signal representing a target brightness, are provided. The mutual conductance of the driving element T, or a parameter reflecting the mutual conductance, is detected, and the data signal to be supplied to the driving element is corrected in accordance with a detection result. More specifically, the data signal is corrected such that a driving current to be supplied to the light emitting element in accordance with the data signal increases as the mutual conductance of the driving element Tdecreases.
