1. A display apparatus comprising:
a display panel;
a data driver which applies a first data voltage to a first display area of the display panel during a first frame and applies a second data voltage to a second display area of the display panel during a second frame, wherein the first display area includes a first-first sub display area and a first-second sub display area, which meet each other only at a center of the display panel, and the second display area includes a second-first sub display area and a second-second sub display area, which meet each other only at the center of the display panel; and
an emission driver which controls an emission of light on the first display area based on the first data voltage during the second frame and an emission of light on the second display area based on the second data voltage during a third frame,
wherein an area of a first visual image recognized to a user due to the emission of the light on the first display area is partially overlapped with an area of a second visual image recognized to the user due to the emission of the light on the second display area in a plan view,
wherein a frequency of an image in the overlapped area between the first visual image and the second visual image is the same as a frequency of input image data input to the display apparatus, and two times of a frequency of other images in the first visual image and the second visual image.
