1. A display apparatus comprising: a display panel including a plurality of pixels; a data driver which applies data voltages to the pixels; a gate driver which applies gate signals to the pixels; and a driving controller which controls the data driver and the gate driver, wherein the driving controller is configured to divide the display panel into a plurality of panel blocks, to calculate a skin color inclusion ratio of each panel block of the plurality of panel blocks based on input image data, to determine at least one face region candidate block among the plurality of panel blocks based on the skin color inclusion ratio, to determine a face region block of the at least one face region candidate block based on the at least one face region candidate block and face matching data, and to perform image quality processing on the face region block; wherein the driving controller is configured to determine the face region block based on a difference value between a pixel value of the face matching data and a pixel value of the input image data for the at least one face region candidate block; wherein the driving controller is configured to count a number of pixels for which the difference value is smaller than a reference value in the face region candidate block, and to determine the face region block based on the counted number of the pixels in each of the at least one face region candidate block; and wherein, when a first number of face region candidate blocks of a first at least one face region candidate block included in a first panel block row of the display panel is less than a second number of face region candidate blocks of a second at least one face region candidate block included in a second panel block row of the display panel, the driving controller is configured to determine the face region block in the first panel block row after determining the face region block in the second panel block row.
