Abstract: An image sensor includes: a substrate including a first area and a second area; a plurality of unit pixels disposed in the substrate, wherein each of the plurality of unit pixels includes a photoelectric conversion layer; a pixel defining pattern separating the unit pixels from each other; a surface insulating film disposed on the substrate; a line structure disposed on the substrate, and including a first interline insulating film and a wire pattern disposed in the first interline insulating film; a micro-lens disposed in the first area; and a light-blocking film disposed in the second area. The light-blocking film includes: a horizontal light-blocking film extending along a top surface of the surface insulating film; and a vertical light-blocking film extending through the surface insulating film and the substrate. The vertical light-blocking film is electrically connected to the wire pattern. The light-blocking film is electrically connected to the pixel defining pattern.
