Abstract
The present invention discloses a pixel unit and a method for manufacturing the same, a display panel, and a display apparatus. A pixel unit comprises a first electrode, a pixel defining layer, a light emitting layer and a second electrode, wherein the second electrode comprises a first portion and a second portion; the pixel defining layer defines a pixel region, the light emitting layer and the first portion of the second electrode are disposed successively within the pixel region, and an upper surface of the first portion of the second electrode is substantially in same plane with an upper surface of the pixel defining layer; and, the second portion of the second electrode is positioned over the first portion and is connected with a second electrode of an adjacent pixel unit. With the technical solutions of the present invention, phenomenon including fractures, abscissions, bubbles and the like due to existence of difference in height in the pixel region will be eliminated, averting adverse influence resulting in failures of the display apparatus.
