Abstract: A display substrate has at least one display region and at least one non-display region, and a non-display region is located at at least one side of a display region. The display substrate includes a base, a plurality of light-emitting devices, and an encapsulation layer. The plurality of light-emitting devices are located in the at least one display region and disposed on a side of the base. The encapsulation layer is disposed on a side of the plurality of light-emitting devices facing away from the base, and configured to encapsulate the plurality of light-emitting devices. A surface, proximate to the base, of a portion of the encapsulation layer located in the non-display region is unevenly arranged.

Abstract: The present disclosure discloses a display panel and a display device including the display panel. The display panel includes an underlying film, a plurality of display units, and a plurality of stretching units. Both the plurality of display units and the plurality of stretching units are arranged on the underlying film. Each of the stretching units includes an annular deformation portion and a plurality of connection portions, one end of each of the connection portions is connected to the deformation portion while the other end of each of the connection portions is connected to the display unit. The stretching unit is constructed in such a way that the deformation portion of the stretching unit is elastically deformed when the display panel is stretched.

Abstract: The present disclosure provides a mask plate and a method for manufacturing the same. The mask plate comprises a body provided with a plurality of openings, in which a first surface of the body is provided with cofferdams each surrounding a corresponding opening, and each cofferdam is configured to confine a diffusion range of a material deposited on a substrate through the opening. In the present disclosure, by providing, on a surface of the body of the mask plate, cofferdams each surrounding edges of each corresponding opening, the cofferdams can effectively prevent the deposition material from depositing into an invalid region, thus CVD shadow can be reduced and the packaging effect can be improved in the process of film deposition or evaporation by chemical vapor deposition (CVD).
