• at least one supporting structure, arranged on one side, facing away from the first substrate, of the at least one underlaying structure,
• wherein an orthographic projection of the supporting structure on the first substrate is within a range of an orthographic projection of the underlaying structure on the first substrate;
• wherein the display panel further comprises:
• a color light filter layer arranged in the display region, and a plurality of spacers arranged on one side, facing away from the first substrate, of the color light filter layer;
• wherein the plurality of spacers are divided into a plurality of main spacers and a plurality of sub-spacers;
