Abstract
A display device according to the present invention includes: a variable voltage source which supplies a supply voltage to an organic EL display unit; and a voltage regulating unit which regulates an external application voltage output by the variable voltage source, the organic EL display unit further includes an anode-side power source line network and a cathode-side power source line network connected to the pixels and the variable voltage source, the display device further includes a voltage measuring unit which measures a voltage for a monitor pixel, and the voltage regulating unit which calculates distributions of voltage drop amount generated in the anode-side power source line network and the cathode-side power source line network, calculates a voltage for the monitor pixel from the distributions of the voltage drop amount calculated, and regulates the supply voltage based on the calculation result and the voltage measured by the voltage measuring unit.
