An electronic apparatus includes: a display layer configured to display images; and a sensor layer on the display layer and comprising a sensing region and a non-sensing region; wherein the sensor layer includes: first sensing electrodes extending on the sensing region in a first direction and arranged in a second direction crossing the first direction; second sensing electrodes extending on the sensing region in the second direction and arranged in the first direction; and first sensing signal lines connected to the first sensing electrodes, respectively, through a contact part overlapping the sensing region, wherein a length of each of the first sensing electrodes in the first direction is greater than a length of each of the second sensing electrodes in the second direction, and the first sensing electrodes have a same length in the sensing region.
