Electronic equipment, display panel and preparation method thereof

The embodiment of the invention provides electronic equipment, a display panel and a preparation method thereof, and relates to the technical field of display, and the display panel comprises a substrate, a pixel defining layer and an isolation structure. The pixel defining layer is located on one side of the substrate, the pixel defining layer is provided with a pixel opening, the pixel opening comprises a first opening and a second opening which are communicated in the thickness direction of the display panel, and the first opening is located on the side, close to the substrate, of the second opening; the orthographic projection of the first opening on the substrate is located in the orthographic projection area of the second opening on the substrate, and the area of the first opening is smaller than that of the second opening. According to the display panel, the pixel opening can penetrate through the pixel defining layer based on the isolation structure, the pixel opening comprises the first opening and t
