1. An electronic device comprising:
a display layer; and
a sensor layer disposed on the display layer, and including a sensing electrode,
wherein the display layer comprises
a plurality of first pixels,
a plurality of second pixels spaced apart from the plurality of first pixels in a first direction, and
a plurality of third pixels alternately arranged with the plurality of first pixels along a second direction,
the plurality of second pixels are alternately arranged along the second direction, and two adjacent second pixels are defined as a pixel group,
the two adjacent second pixels are spaced apart by a first distance in the second direction, and the pixel group is spaced apart by a second distance in the second direction from another pixel group adjacent thereto, the second distance being greater than the first distance,
the sensing electrode comprises a first sensing electrode and a second sensing electrode each including a plurality of sensing patterns, and
the plurality of sensing patterns each comprise a first portion adjacent to the plurality of first pixels and the plurality of third pixels, and a second portion extending, when seen on a plane, in the first direction between the pixel group and the other pixel group adjacent thereto,
wherein the second portion is provided in plurality, and
the plurality of second portions extend in the first direction, are spaced apart from each other in the second direction, and are disposed between the pixel group and the other pixel group adjacent thereto.
