Abstract
A display panel, a mask, and a display device are provided. The display panel includes a substrate, a first flexible layer, a first inorganic layer, and a second inorganic layer stacked from bottom to top. A crack blocking structure is disposed on the first flexible layer, and the crack blocking structure includes a cutting portion and a concave portion located at two sides of the cutting portion. The first inorganic layer and the second inorganic layer are disconnected at an opening of the concave portion. The concave portion is configured to block cracks of the first inorganic layer and the second inorganic layer from extending to two sides of the crack blocking structure when the cutting portion cuts the display panel.
