Abstract

Disclosed is a photoreactive sensor including an optical amplification phototransistor, in which a non-overlapping region that does not overlap with a local gate electrode between a source electrode and a drain electrode is formed and which senses an optical image through the non-overlapping region for amplify photoconductivity; and a contact light emitting device that is formed on the optical amplification phototransistor and generates the optical image corresponding to a contacted surface upon contact with an object.
