Display panel and display device

A display device, comprising a display panel, wherein the display panel comprises a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate and the second substrate are disposed opposite to each other, and the liquid crystal layer is located between the first substrate and the second substrate;

• the first substrate is provided with a planarization layer, a surface of a side of the planarization layer facing the liquid crystal layer is provided with a plurality of groove structures and a protrusion structure located between adjacent groove structures of the plurality of groove structures, the second substrate is provided with color film structures which are arranged at intervals, and a color film structure of the color film structures at least partially overlaps with a groove structure of the plurality of groove structures in a thickness direction of the display panel;
• and
• a plurality of first support structures are disposed between the first substrate and the second substrate, and a first support structure of the plurality of first support structures and the planarization layer are disposed at intervals in the thickness direction of the display panel.
