Display panel, method for manufacturing the same, display device and displaying method

A method for manufacturing a display panel, the method comprising:

• forming a thin film transistor on a substrate;
• forming an insulating layer to cover the substrate and the thin film transistor;
• forming a first electrode and a second electrode electrically insulated with each other on the insulating layer, wherein an orthographic projection of the first electrode on the substrate does not overlap with an orthographic projection of the thin film transistor on the substrate, and wherein an orthographic projection of the second electrode on the substrate overlaps with an orthographic projection of the thin film transistor on the substrate;
• forming a light emitting layer on the first electrode and the second electrode;
• and
• forming a third electrode and a fourth electrode on the light emitting layer, wherein an orthographic projection of the third electrode on the substrate overlaps with an orthographic projection of the first electrode on the substrate, and wherein an orthographic projection of the fourth electrode on the substrate overlaps with an orthographic projection of the second electrode on the substrate,
• wherein the first electrode, the third electrode, and a first portion of the light emitting layer between the first electrode and the third electrode constitute a first pixel, and wherein the second electrode, the fourth electrode, and a second portion of the light emitting layer between the second electrode and the fourth electrode constitute a second pixel.
