1. A display apparatus comprising:
light emitting elements that are driven by current; and
a voltage control unit that controls a driving voltage for driving the light emitting elements based on at least one of a temperature of the display apparatus and a display luminance of the display apparatus such that the driving voltage decreases as the temperature of the display apparatus increases and the driving voltage decreases as the display luminance decreases,
wherein the voltage control unit performs control such that an amount of change in the driving voltage per unit time does not exceed a predetermined limited range, and
wherein the predetermined limited range is determined based on a relationship between the change in the driving voltage and a change in a light emission luminance of the light emitting elements.
