摘要： Disclosed is a display apparatus. The display apparatus includes: a display panel including a pixel array in which pixels including a plurality of inorganic light-emitting elements are arranged in a plurality of row lines, and sub-pixel circuits provided for each of the plurality of inorganic light-emitting elements and providing a driving current to the inorganic light-emitting elements; and a drive unit is configured to set image data voltages to sub-pixel circuits of the display panel in a row line order during a data setting period, and drive the sub-pixel circuits such that a driving current is sequentially provided to the inorganic light-emitting elements on the basis of a sweep signal and the image data voltages during a light-emitting period. The sub-pixel circuits comprise: a capacitor having one end to which the sweep signal is applied; and a first driving transistor connector to the other end of the capacitor, receiving the sweep signal through the capacitor in a light-emitting period, and controlling a time when the driving current is provided to the inorganic light-emitting elements on the basis of the sweep signal. The drive unit applies a first voltage to the one end of the capacitor separately from the sweep signal in the data setting period.
