Preparation method of display panel, display panel and displaying device

A display panel, comprising a plurality of first-color subpixels, wherein each first-color subpixel comprises:

• a base, the base comprising a first driving electrode and a second driving electrode;
• at least one first electrode, disposed at a side of the base and is connected to the first driving electrode;
• at least one second electrode, disposed at a same side of the base with the first electrode and is connected to the second driving electrode;
• an intermediate layer, disposed between the first electrode and the second electrode;
• wherein the first electrode and the second electrode divide the first-color subpixel into a plurality of secondary pixels, the first electrode and the second electrode are insulated with each other via the intermediate layer, and are respectively connected to the first driving electrode and the second driving electrode, and control the secondary pixels independently;
• wherein a front projection of the first electrode on the base is adjacent to or partially overlaps with the front projection of an adjacent second electrode on the base.
