Abstract
A display panel is disclosed. The display panel includes a photosensitive device. The photosensitive device includes a barrier component and a second active pattern. The second active pattern includes a second lightly-doped part, a second intrinsic part surrounding the second lightly-doped part, and a second heavily-doped part surrounding the second intrinsic part. In a film thickness direction, the barrier component overlaps the second intrinsic part. A dark current of the photosensitive device is reduced by the second intrinsic part, thereby improving sensitivity.
