Display panel, mask assembly and display device

The invention discloses a display panel, a mask assembly and a display device. The display panel comprises a plurality of pixel units arranged in an array, and each pixel unit comprises a first sub-pixel, a second sub-pixel and two third sub-pixels which are located in a virtual hexagon; the first sub-pixel is adjacent to the second sub-pixel, and the two third sub-pixels are adjacent to the firstsub-pixel and the second sub-pixel; the adjacent pixel units in the column extension direction share the first sub-pixel and the second sub-pixel, and the adjacent pixel units in the row extension direction share one third sub-pixel. Any one first sub-pixel in the display panel, one second sub-pixel adjacent to the first sub-pixel and two third sub-pixels adjacent to the first sub-pixel and the second sub-pixel can form an independent pixel unit. Therefore, a high-resolution display effect can be achieved between the sub-pixels by means of the low-resolution physical resolution according to the color-borrowing princi
