A display panel includes a substrate, a light-blocking layer, a plurality of connection leads and a light-emitting device layer. The substrate includes a first surface and a second surface opposite to each other, and a plurality of side surfaces connecting the first surface and the second surface. At least one of the plurality of side surfaces is a selected side surface. The light-emitting device layer is disposed on the second surface. Each of the plurality of connection leads includes a first portion located on the first surface of the substrate, a second portion located on the selected side surface of the substrate and a third portion located on the second surface of the substrate. The light-blocking layer is located between the plurality of connection leads and the substrate, and is at least located between first portions of the plurality of connection leads and the first surface of the substrate.
