1. An image sensor comprising:
a light sensing element in a substrate;
a plurality of transfer gates (TGs) spaced apart from each other in a horizontal direction substantially parallel to a surface of the substrate, each of the plurality of TGs extending through a portion of the substrate and contacting the light sensing element;
a floating diffusion (FD) region at a portion of the substrate adjacent to the plurality of TGs;
a first division pattern extending at least partially through the substrate in a vertical direction substantially perpendicular to the surface of the substrate, the first division pattern having a first closed shape in a plan view;
a second division pattern connected to the first division pattern and extending from the first closed shape toward an outside of the first closed shape in a horizontal direction to form a second closed shape adjacent to the first closed shape in the plan view; and
a third division pattern connected to the first division pattern and extending from the first closed shape toward a center of the first closed shape,
wherein the FD region is between the plurality of TGs in a plan view.
