Abstract: A display panel includes a first substrate and a second substrate disposed opposite to each other and spaced apart from each other, and a second semiconductor layer. The first substrate includes a first base substrate, a first metal layer, a first semiconductor layer, and a second metal layer. The first metal layer is disposed on the first base substrate. The first semiconductor layer is disposed on the first metal layer. The second metal layer is disposed on the first semiconductor layer. The second substrate includes a second base substrate and a third metal layer. The third metal layer is disposed on the second base substrate. The second semiconductor layer is disposed between the first metal layer and the third metal layer. The first semiconductor layer is insulated from the second semiconductor layer.

Abstract: A display panel and a display device are provided. By means of a shielding structure with a floating potential provided over a projection of a sensing read line, when an electrical signal is transmitted on the sensing read line and a pixel data line, a shielding electric field will be formed between the shielding structure and the sensing read line. The presence of the shielding electric field can reduce capacitance between the sensing read line and adjacent pixel data line and effectively improve a signal-to-noise ratio during signal transmission.
