1. A display device comprising:
a display panel configured to display an image;
an input sensor disposed on the display panel and including a first sensing area configured to sense an input, wherein the first sensing area has a first sub-area and a second sub-area; and
a first sensor controller configured to drive the first sensing area,
wherein the input sensor includes:
first sensing electrodes disposed in the first sub-area to receive a first transmission signal from the first sensor controller;
second sensing electrodes disposed in the first sub-area and intersected with the first sensing electrodes;
third sensing electrodes disposed in the second sub-area to receive a second transmission signal having a phase inverted from a phase of the first transmission signal from the first sensor controller;
fourth sensing electrodes disposed in the second sub-area and intersected with the third sensing electrodes;
first transmission lines connected to the first sensing electrodes; and
second transmission lines connected to the third sensing electrodes,
wherein at least one of an amplitude difference between the first transmission signal and the second transmission signal, area differences between the first sensing electrodes and the third sensing electrodes, or length differences between the first sensing electrodes and the third sensing electrodes is set according to a line resistance difference between the first transmission lines and the second transmission lines.
