Abstract
A pixel structure, a display substrate and a display device are disclosed. The pixel structure includes a plurality of reduplicated units, wherein each of the reduplicated units includes: a red sub-pixel (A1), a green sub-pixel (A2), a blue sub-pixel (A3) and a central sub-pixel (W) all in a shape of a triangle, wherein a color of the central sub-pixel (W) is different from that of any of the red sub-pixel (A1), the green sub-pixel (A2) and the blue sub-pixel (A3), and the three sides of the central sub-pixel (W) respectively coincide with one side of the red sub-pixel (A1), one side of the green sub-pixel (A2) and one side of the blue sub-pixel (A3). By designing the shape of the sub-pixel unit to be a triangle, it is possible to allow the red, green and blue sub-pixels (A1, A2, A3) surrounding the three sides of the central sub-pixel (W) and to guarantee the central sub-pixel (W) to be adjacent to the other three sub-pixels (A1, A2, A3), thus increasing the luminance while realizing homogeneous color mixing of different colors of sub-pixels, thereby improving the display quality.
