Display panel having light guiding medium structure and display device

A display device, comprising a display panel, wherein the display panel comprises:

• a substrate;
• and
• pixel units provided on the substrate, wherein the pixel units of at least two different colors are adjacently arranged;
• wherein in a direction facing away from the substrate, one of the pixel units comprises a reflective electrode, a light emitting unit and a color resist, wherein the light emitting unit and the color resist disposed in a same pixel unit have a same color, and a vertical projection of a geometric center of the light emitting unit on the substrate is not overlapped with that of a geometric center of the color resist in the same pixel unit on the substrate;
• wherein a vertical projection of the color resist in the one of the pixel units on the substrate is overlapped with that of the light emitting unit in a pixel unit adjacent to the one of the pixel units on the substrate, wherein the one of the pixel units further comprises a light guiding medium structure disposed between the light emitting unit and the color resist, a gap exists between adjacent light guiding medium structures, and a refractive index of a filler in the gap is smaller than that of the light guiding medium structure.
