Abstract
A photosensor includes a substrate, a sensing device, and a light shielding layer. The sensing device is disposed on the substrate and includes a first electrode, a photo-sensing layer, and a second electrode. The first electrode is disposed on the substrate. The photo-sensing layer is disposed on the first electrode. The second electrode is disposed on the photo-sensing layer, and the photo-sensing layer is interposed between the first electrode and the second electrode. The light shielding layer is disposed on the second electrode. Here, the photo-sensing layer has a shielded portion shielded by the light shielding layer and a photo-receiving portion not shielded by the light shielding layer, and an area of the shielded portion is 55% to 99% of an entire area of the photo-sensing layer.
