摘要： Provided is a method for driving a display device including: a display unit having a sub-pixel having a first light emitting element (organic EL element) and a first driving transistor for supplying a first electric current corresponding to a first gray level signal, and a sub-pixel having a second light emitting element (organic EL element) and a second driving transistor for supplying a second electric current corresponding to a second gray level signal; and a power supply unit configured to apply a power supply voltage to each sub-pixel via an electric current path that is common to the sub-pixel and the sub-pixel. The driving method includes correcting the first gray level signal based on the first gray level signal and the second gray level signal so as to compensate for a reduction in the first electric current caused by a voltage drop that occurs in the electric current path.
