Abstract
The present application provides a mask assembly and a display device. The display device comprises a display area and at least one non-display area, the display area surrounding the non-display area; the display device further comprises a transitional-display area adjoining the non-display area as well as the display area, respectively, wherein both the display area and the transitional-display area are used to display static or dynamic images; a thickness of a first electrode in the transitional-display area is smaller than or equal to a thickness of the first electrode in the display area. The presence of the transitional-display area prevents incomplete display caused by incomplete coverage of the evaporation material in the display device, such as black-edged display formed in an area where a connection bridge is located, thereby improving the display integrity.
