Abstract
An electroluminescent display device includes a display panel including a plurality of pixels each including a light-emitting element driven according to a driving current flowing between a high-level power supply voltage and a low-level power supply voltage, and an EVDD adjustment circuit configured to cut off the high-level power supply voltage for a black period in which emission of light from the light-emitting element stops in one frame such that the high-level power supply voltage is not applied to the pixels.
