Abstract

Abstract A highly sensitive and high-density picture element solid-state image pickup element. The image pickup element includes a picture element portion formed on a semiconductor wafer, a driving circuit for driving the picture element portion, a photoconductive layer formed on the picture element portion and a transparent electrode formed on the photoconductive layer. On top of the transparent electrode is a layer of photosetting resin and a color filter bonded to the photosetting resin with an adhesive agent having substantially similar or the same composition and optical properties as the photosetting resin.
