Abstract:

The present invention provides a mask, a display panel, and a display device. The mask is used for vapor deposition of a film layer of a display panel, and comprises a first area and a second area. The first area is an area for vapor deposition of a film layer in a first pixel density area of the display panel, and the second area is an area for vapor deposition of a film layer in a second pixel density area of the display panel. The pixel density of the first pixel density area is greater than that of the second pixel density area. The second area comprises a covering area and an opening area. The position of the covering area corresponds to a position of the display panel where no vapor-deposited film layer is needed.
