Abstract

An image sensor includes a substrate including a sensor array area, a pad area, and a circuit area, a wiring layer on the pad area, and a light-shielding pattern on the sensor array area. The sensor array area includes a first area including active pixels and a second area including optical back pixels. The wiring layer is apart from the substrate by a first distance on the pad area. The light-shielding pattern includes a first portion spaced apart from the substrate by a second distance less than the first distance, a second portion disposed between the first portion and the wiring layer and extending on the same level as the wiring layer, and a third portion disposed between the first portion and the second portion and integrally formed with the first portion and the second portion.
