Abstract: A display panel (10), comprising a plurality of pixel units (12) arranged in an array, each pixel unit (12) comprising one first sub-pixel (122), one second sub-pixel (124) and two third sub-pixels (126) located in a virtual hexagon; the first sub-pixel (122) is adjacent to the second sub-pixel (124), and the two third sub-pixels (126) are both adjacent to the first sub-pixel (122) and the second sub-pixel (124); and pixel units (12) adjacent in the column extension direction share the first sub-pixel (122) and the second sub-pixel (124), and pixel units (12) adjacent in a row extension direction share one third sub-pixel (126). The present application further discloses a mask assembly and a display device.

Abstract: The disclosure provides a pixel array and a display device. The pixel array includes a plurality of sub-pixels, each of which has a virtual pixel center, the plurality of sub-pixels include first sub-pixels, second sub-pixels, and third sub-pixels; virtual centers of two first sub-pixels and two third sub-pixels are sequentially connected to form a second virtual quadrangle; a first virtual polygon includes four second virtual quadrangles in an array and sharing adjacent sides; and the first sub-pixels and the third sub-pixels are at vertex angles or sides of the first virtual polygon and are alternately on the vertex angles or the sides of the first virtual polygon along a clockwise direction; the first virtual polygon has a first virtual point therein, lines connecting the first virtual point and virtual centers of the four third sub-pixels on the first virtual polygon divide the first virtual polygon into four virtual isosceles trapezoids.
