Abstract: A foldable display device includes: a foldable display panel including a folding line, a first display area, and a second display area which displays a virtual keyboard including virtual keys in a keyboard mode; a touch panel including touch electrodes for receiving a touch input; 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 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. The driving controller activates a typographical error notification function and a typographical error correction function based on the touch data.
