ABSTRACT:
Provided are a detection element Em used for controlling a value of a drive voltage for each light emitting element constituting a display pixel, and a leakage detection circuit4which separates the detection element Em from a current source I1when this detection element Em is in a leakage state. Further provided are a pseudo leakage setup means5with which a potential of an anode terminal in the above-mentioned detection element can be set as a pseudo leakage potential which is a potential when the detection element is in the leakage state, and an operation detection means6to verify that the leakage detection circuit4operates normally when operating the above-mentioned pseudo leakage setup means5.
