A pixel structure and a display device are provided. The pixel structure includes: a plurality of pixel units arranged in a matrix, each pixel unit including first to seventh subpixels arranged sequentially in a row direction, and the first subpixel, the second subpixel, the third subpixel and the fourth subpixel being different from one another in color. Each subpixel among the first to third subpixels has a same color as that of one subpixel among the fifth to the seventh pixels, respectively. The number of colors of the pixel structure becomes from original three to at least four, added subpixels are shared by pixels on both sides thereof, colors illustrated are more diversified by color modulation, and gamut of the display device is improved.
