Orthographic projections of portions of the first light-emitting layer 32 and the first anode 31 extending to the second sub-pixel region 2 on the substrate 10 do not overlap with the orthographic projection of the through hole 111 on the substrate 10, i.e., there is no overlapped portion therebetween. At the same time, the orthographic projection of the first driving circuit 5 of the first sub-pixel region 1 does not overlap with the orthographic projection of the second sub-pixel region 2 on the substrate 10, i.e., there is no overlapped portion therebetween, which avoids the light emitted from the first light-emitting layer 32 is incident on the light detecting unit 4 through the through hole 111 to cause interference, and affect detection effect. In this embodiment, by extending the first light-emitting layer 32 and the first anode 31 to the second sub-pixel region 2, and avoiding projections of the first light-emitting layer 32 and the through hole 111 on the substrate 2 from overlapping, so that the detection accuracy is ensured and the display effect is enhanced.
