    Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel is configured to display an image. The gate driver is configured to output a gate signal to the display panel. The data driver is configured to output a data voltage to the display panel. The display panel includes a first subpixel row including first subpixels having a first color and a second subpixel row including second subpixels having a second color. A first gate off voltage of a first gate signal applied to the first subpixel row to turn off switching elements of the first subpixel row is different from a second gate off voltage of a second gate signal applied to the second subpixel row to turn off switching elements of the second subpixel row.
