The present invention provides a pixel driving structure and a display device. The pixel driving structure includes: several scanning lines and several data lines, the scanning lines and the data lines are interlaced to define pixels distributed in an array, and the same data line Connect pixels of the same color; when the pixel driving structure displays a single-color or two-color mixed color picture, the driving voltage on the data line is in a continuous high potential state, so the single-color or two-color mixed color picture is a light-loaded picture. In this case, the pixel The charging ability is strong, which effectively reduces the risk of poor picture display due to insufficient charging of pixels; at the same time, one data line only charges pixels of one color, and the driving voltage on the data line is in a state of continuous high potential, avoiding The problem of incorrect charging avoids the problem of color shift due to incorrect charging, which eventually causes poor picture display; thereby greatly improving the display effect of the display panel.
