Abstract: A photosensitive device includes a substrate, an active element layer, a first photosensitive element and a second photosensitive element. Each first photosensitive element includes a first lower conductive structure, a first photosensitive layer, and a first upper conductive structure stacked in sequence. Each second photosensitive element includes a second lower conductive structure, a second photosensitive layer, and a second upper conductive structure stacked in sequence. The first upper conductive structure includes an opaque electrode or a semi-transparent electrode, and the second upper conductive structure includes a transparent electrode. The first upper conductive structure is configured to make a signal difference between a photocurrent signal and a dark current signal of the first photosensitive element smaller than a signal difference between a photocurrent signal and a dark current signal of the second photosensitive element.
