Display panel and display apparatus

A display panel, comprising:

• a base plate;
• a pixel electrode layer arranged on the base plate and comprising a plurality of pixel electrodes distributed in an array;
• and
• a pixel definition layer located at a side of the pixel electrode layer away from the base plate, the pixel definition layer comprising a plurality of first isolation portions distributed at intervals, each of the first isolation portions being ring-shaped and surrounding and defining a pixel opening, and an edge of a first orthographic projection of the pixel electrode on the base plate being within a second orthographic projection of the first isolation portion on the base plate,
• wherein the display panel further comprises a plurality of light-emitting units emitting lights of different colors, each of the light-emitting units being located in one pixel opening, the second orthographic projection comprising second inner edges facing the pixel opening and second outer edges away from the pixel opening, the second outer edges enclosing an isolation area, and isolation areas where at least two light-emitting units emitting lights of a same color are located being of different sizes.
