Abstract: An input sensor includes a plurality of first sensor electrodes extending along a first direction in an active area, a plurality of second sensor electrodes extending along a second direction. A sensor driver is spaced apart from the active area in the second direction. A plurality of first sensor lines connects the first sensor electrodes to the sensor driver and overlap the active area. A plurality of second sensor lines connect the second sensor electrodes to the sensor driver. The first sensor electrodes include first to n-th row sensor electrodes sequentially arranged in a direction adjacent to the sensor driver. The number of first sensor lines electrically connected to the first row sensor electrode is larger than the number of first sensor lines electrically connected to the n-th row sensor electrode.
