Abstract
In a display device () provided with pixel circuits including organic EL elements, a display control circuit () calculates a voltage drop amount VRI of a power line due to display for each frame on the basis of an integrated value for display data, and a tone voltage generation circuit () adjusts reference voltages for a tone voltage on the basis of the integrated value in order to compensate for the voltage drop amount VRI. As a result, it is possible to compensate for the voltage drop of the power line with accuracy without increasing power consumption and the wiring in the pixel circuits.
