Display apparatus and electronic apparatus including the same

A display apparatus comprising:

• a display panel including a pixel configured to emit a light based on a first power voltage and a second power voltage less than the first power voltage;
• a data driver configured to output a data voltage to the pixel;
• and
• a power voltage generator configured to output a data power voltage, a maximum data voltage and a minimum data voltage to the data driver,
• wherein a luminance mode varies, and the data power voltage and the maximum data voltage are varied, and
• the minimum data voltage is fixed.
