1. A display device comprising:
a display panel including a plurality of first pixels disposed in a first display area and a plurality of second pixels disposed in a second display area adjacent to the first display area;
a gate driver disposed in the second display area of the display panel to overlap a portion of the second pixels and configured to drive the first and second pixels;
a controller configured to receive image data and convert the image data to image signals; and
a data driver configured to convert the image signals to data signals and outputting the data signals to the first and second pixels,
wherein the second display area comprises an effective area in which light emitting elements of the second pixels are disposed and a non-effective area in which the light emitting elements are not disposed, the non-effective area is disposed between the effective area and the first display area,
wherein the controller compensates for effective data corresponding to the second pixels and reflects the compensated effective data to the image signals,
the controller comprises:
a data compensator configured to extract image data with respect to the second display area from the image data, compensates for the effective data corresponding to the second pixels among the extracted image data using non-effective data corresponding to non-effective area among the extracted image data to generate compensation data, and provide the compensation data to the second pixel to prevent a phenomenon in which a boundary between the first display area and the effective area is viewed,
wherein the data compensator comprises:
an image analyzer configured to extract first image data with respect to the first display area and second image data with respect to the second display area from the image data; and
a data processor configured to receive the second image data, set reference effective data from the effective data, set peripheral data adjacent to the reference effective data, and compensate for the reference effective data based on the peripheral data to generate the compensation data,
wherein the peripheral data include at least one non-effective data and at least one adjacent effective data adjacent to the reference effective data.
