Abstract
The present invention discloses a pixel unit, a method of manufacturing the same and a display device. The pixel unit comprises an anode layer, a pixel definition layer, an organic light-emitting layer and a cathode layer, wherein the anode layer includes a plurality of pixel anodes in an array arrangement, and the pixel definition layer is disposed on the anode layer and includes a plurality of spaced pixel definition units, wherein the pixel definition units correspond to the pixel anodes one by one, and each pixel definition unit delimits a light-emitting region on the corresponding pixel anode, and the organic light-emitting layer is provided within the light-emitting regions, and the cathode layer is provided on the organic light-emitting layer. The present invention remarkably increases light extraction efficiency by improving the structure of the pixel unit.
