Abstract
An electronic device includes: a display layer; and a sensor layer on the display layer, the sensor layer including: a first sensing electrode having a first sub-sensing electrode and a second sub-sensing electrode electrically separated from the first sub-sensing electrode; and a second sensing electrode intersecting the first sensing electrode, wherein the sensor layer is configured to sense an external input through a change in mutual capacitance between the first sensing electrode and the second sensing electrode, and the sensor layer is further configured to sense an input by an active pen through a change in capacitance of each of the first sub-sensing electrode, the second sub-sensing electrode, and the second sensing electrode.
