Display Device

A display apparatus includes a pixel row including a plurality of pixels. Each pixel includes a driving transistor that provides a driving current to a light emitting element, and includes a gate electrode, a first electrode, and a second electrode. The first transistor includes a gate electrode that receives a first scan signal, a first electrode receives a data voltage, and a second electrode. The second transistor includes a gate electrode that receives a second scan signal, a first electrode that receives an initialization voltage, and a second electrode. A ripple detection unit detects ripples that occur in pixel rows in the display apparatus. A compensation image data calculation unit calculates the magnitude of the compensation image data based on the difference between the voltage level of the initialization voltage of a pixel row in which the ripple occurs and a reference initialization voltage level.
