Filed: 1993-08-11
Abstract: PURPOSE:To control the leakage current of a photosensor element used in a fully contact type image sensor and increase an optical speed of response. CONSTITUTION:AN insulating black thin film 2 is formed as a light shielding layer on a translucent insulating substrate 1 and a photoelectric conversion layer 8 is also provided on the film 2 through an insulating film 7.
