The embodiments of the present invention relate to the field of display technologies, and in particular, to a pixel arrangement structure and a display device.

Organic light emitting diode (OLED) displays have been gradually applied to display panels of various display devices due to their advantages of high contrast, wide viewing angle, fast response speed, and high photoelectric conversion efficiency. In the past, most of the evaporation process was used in the process of manufacturing the display panel, and the organic material of any one of the red, blue and green colors needs to be masked by the mask to cover the sub-pixel regions of the other two colors, and in the above evaporation process. It is easy to cause misalignment in the row direction or column direction, causing a problem of color mixing of each sub-pixel. In order to accommodate the manufacturing technology of the mask and the evaporation process, the conventional OLED pixel arrangement generally has certain innate limitations in the arrangement. However, with the advancement of the OLED display panel process, the existing pixel arrangement structure and display device have room for improvement.
