An image sensor is provided. The image sensor includes a pixel sensing circuit corresponding to at least a first pixel region and a second pixel region adjacent to each other, a pixel electrode disposed on the pixel sensing circuit, and a opto electrical conversion layer including a photo sensing layer and a carrier transport layer disposed on the pixel sensing circuit and the pixel electrode. The pixel electrode is electrically connected to the pixel sensing circuit and includes a plurality of first electrodes and a plurality of second electrodes. The first electrodes and the second electrodes are coplanar and have different polarities. The first electrode or the second electrode located in the first pixel region is adjacent to the first electrode or the second electrode having the same polarity located in the second pixel region.
