The array substrate has a first through hole, and the array substrate includes a plurality of pixel units, a plurality of scan lines, and a plurality of data lines. The scan lines are electrically connected to the pixel units. The data lines intersect with the scan lines, and the data lines are electrically connected to the corresponding pixel units. The opposite substrate is disposed opposite to the array substrate, and the opposite substrate has a second through hole. The closed sealing element is disposed between the array substrate and the opposite substrate, and the closed sealing element has a third through hole. The first through hole, the second through hole, and the third through hole form an opening. ## Claims ### Claim 1 A display panel, comprising: an array substrate having a first through hole, comprising: a plurality of pixel units;
