Abstract: A display device including a first substrate, a sensing element, a display switch element and a blocking structure is provided. The first substrate has a first top surface perpendicular to a first direction. The sensing element is disposed on the first substrate and includes an active layer having a channel region. A first distance is formed between a channel top surface of the channel region and the first top surface of the first substrate along the first direction. The display switch element is disposed on the first substrate and adjacent to the sensing element. The blocking structure is disposed on the sensing element. The blocking structure has a bottom surface and a first opening, the first opening corresponding to the channel region of the sensing element. A second distance, greater than the first distance, is formed between the bottom surface and the first top surface along the first direction.
