US Patent 10991754 Display device with stacking design of sensing element

A display device including a display panel is provided. The display panel includes a first substrate, a first transistor, a sensing element, a first conductive layer and a second conductive layer. The first transistor is disposed on the first substrate. The sensing element is disposed on the first substrate and electrically connected to the first transistor. The sensing element includes a first-type semiconductor layer, an insulation layer and a second-type semiconductor layer. The insulation layer is disposed on the first-type semiconductor layer. The second-type semiconductor layer is disposed on the insulation layer. The first conductive layer is disposed between the first substrate and the sensing element, and the first conductive layer contacts with and electrically connected to the first-type semiconductor layer. The second conductive layer is disposed on the sensing element, and the second conductive layer contacts with and electrically connected to the second-type semiconductor layer.
