    Abstract: At least one example embodiment discloses an image sensor with an improved light utilization efficiency based on reflective color filters. Since the image sensors may use most of an incident light for forming an image by using reflective color filters, light loss due to light absorption may be reduced. Therefore, light utilization efficiency of the image sensors may be improved while embodying color purity.
