The invention discloses a pixel structure and a display device, and belongs to the technical field of display. The pixel structure and the display device solve the technical problem that the manufacturing process of a color film substrate with four-color pixels is complex. The pixel structure comprises four sub-pixels of different colors, wherein a first color ring resistor is arranged in the first sub-pixel, a second color ring resistor is arranged in the second sub-pixel, a third color ring resistor is arranged in the third sub-pixel, and any two color ring resistors of the first color ring resistor, the second color ring resistor and the third color ring resistor are arranged in the fourth sub-pixel. The pixel structure can be used in display devices such as a liquid crystal display television, a liquid crystal display, a mobile phone and a tablet personal computer.
