a touch panel including a plurality of touch electrodes and which receives a touch input by using the touch electrodes;
a data driver which outputs a data voltage to the foldable display panel;
a driving controller which controls the data driver; and
a touch data generator which generates touch data for input key values based on the touch input, determines at least two input key values of the input key values as a typographical error when the at least two input key values are simultaneously input, and outputs the touch data including the at least two input key values determined as the typographical error to the driving controller,
wherein the driving controller activates a typographical error notification function for notifying occurrence of the typographical error and a typographical error correction function for correcting the typographical error based on the touch data,
