Abstract

An image sensor includes a sensing layer, a filter unit, and a conductive layer. The filter unit is disposed on the sensing layer. The conductive layer surrounds the filter unit, and is disposed on the sensing layer. Therefore, light passing through the filter unit and falling on an adjacent sensing unit is minimized, and the image quality of the image sensor is improved.
