Embodiment Construction

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments, however, can be embodied in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0040] In related technologies, such as figure 1 As shown, when preparing the transparent organic electroluminescent display panel, the thin film transistor 110 and the anode layer 120 are formed on the transparent substrate 1 in sequence, and then the pixel defining layer 130 is used to define the light-emitting area 100 and the transparent area 200 on the anode layer 120. Then, a light-emitting functional layer 140 , a ...

Abstract

The invention provides a display panel, a manufacturing method thereof and a display device. The manufacturing method of the display panel comprises the steps: after a pixel defining layer is prepared, an auxiliary layer with a certain gap with the pixel defining layer is prepared in a transparent area; then a light-emitting function layer and a cathode layer are formed on the pixel defining layerand the auxiliary layer; and finally, the auxiliary layer is stripped, and the light-emitting function layer and the cathode layer in the transparent area can be stripped at the same time. Accordingto the method, the light-emitting function layers and the cathode layers in the transparent area are reduced, the number of the film layers is reduced, particularly, the cathode layers which greatly influence the light transmittance are removed, the light transmittance of the transparent area is greatly improved, and the transparent display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a method for manufacturing the same, as well as a display device including the display panel. Background technique [0002] At present, the demand for transparent displays in various fields such as vehicle, smart home, and shop windows is increasing day by day, and the development of transparent organic electroluminescent display panels has received more and more attention. [0003] The sub-pixel area of ​​the transparent organic electroluminescence display panel includes a first area and a second area, but when preparing the transparent organic electroluminescence display panel, due to process limitations, the light-emitting functional layer and the cathode layer and other film layers can only be made into A whole film layer, that is to say, these film layers also exist in the second area, but these film layers have a great influence on the li...
