1. An electronic device comprising:
an input sensor comprising:
a first sensing electrode,
a second sensing electrode crossing the first sensing electrode,
a first signal line connected to an end of the first sensing electrode,
a second signal line connected to an end of the second sensing electrode, and
a third signal line connected to another end of the second sensing electrode; and
a circuit board electrically connected to the input sensor, the circuit board comprising:
an insulating layer,
