Abstract: An image sensor includes a substrate including a plurality of photoelectric conversion elements and a variable filter layer disposed on the substrate. The variable filter layer includes a plurality of first electrodes extending in a first direction, and having a first width in a second direction, a first electro-optical material layer disposed on the plurality of first electrodes, a light-transmitting electrode disposed on the first electro-optical material layer, a second electro-optical material layer disposed on the light-transmitting electrode, and a plurality of second electrodes disposed on the second electro-optical material layer, extending in the second direction, and having a second width in the first direction.
