The display panel includes data lines, horizontal scan lines, vertical scan lines, pixels at crossing regions of the data and horizontal scan lines, and contact holes that connect the horizontal scan lines to the vertical scan lines. The scan driver provides scan signals to the display panel through the vertical scan lines. The data driver provides data signals to the display panel through the data lines. The storage area stores location information of the contact holes.
