Abstract: PURPOSE:To reduce the overlooking in reading of optical information by providing a conductive layer between an insulation substrate and a photoconductive material in such a way as not to contact with electrodes opposite to nearly the entire surface of the photodetection surface of the photoconductive material. CONSTITUTION:This sensor is constituted of a photoconductor 4-1, a pair of electrodes 4-1, 4-3, a conductive metallic film 4-4, and an insulator substrate 4-5. Here, a light irradiating part is shown by (a), (b), (c), and the photoconductive material having large conductivity by (b'), (c'). When this is exposed like the circles (a), the conductivity in the (a) increases extremely and contacts between both electrodes and therefore optical information can be detected. Further when the case in which the (b) and (c) are exposed simultaneously, the conductivity in the photoconductor part of the (b'), (c') is increased by the exposure of the (b), (c), and both electrodes conduct through the (b'), (c') and the conductor metallic part 4-4; hence, the optical information is read.

Abstract: PURPOSE:To prevent a short-circuit between wirings due to hillock and current leakage by providing substantially parallel slits on the side of an Al wiring at least on part of the wiring. CONSTITUTION:A plurality of slits 5 which are intermittently connected are provided along the side of an Al wiring 1, and the wiring 1 is separated in space into a relatively wide first part 6 and a relatively narrow second part 7.

Therefore, even if other Al wiring 2 is provided near the part 7, a short-circuit is not substantially generated by the hillock 4 generated from the second part. The hillock generated from the part 6 can be prevented from being brought into contact with other Al wiring by the part 7.
