Problems solved by technology

When the thickness of the cathode is small, the cathode has a large impedance, which is not conducive to electron injection at this time, thereby reducing the conduction capacity of the current and limiting the improvement of the display quality

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a thin film transistor array substrate, an organic light emitting functional layer, a pixel definition layer, a negative electrode layer and a transparent packaging layer; pixel definition components of the pixel definition layer are arranged on at least one side of the part, corresponding to the pixel unit of the display panel, in the organic light emitting functional layer; the negative electrode layer has predetermined light transmittance; the negative electrode layer covers the organic light emitting functional layer and the pixel definition layer; the thickness of the part, corresponding to an opening region of the display panel, of the negative electrode layer is less than the thickness of the part, corresponding to a non-opening region of the display panel, of the negative electrode layer; and the transparent packaging layer covers a conductive metal film layer and a conductive metal component layer, wherein the display panel is used for outputting a displayed image on the outer surface of the transparent packaging layer. By virtue of the display panel and the manufacturing method thereof, the electron injection efficiency of the display panel can be improved, and the display quality of the display panel can be further improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. 【Background technique】 [0002] Traditional OLED panels are generally bottom-emitting display panels, that is to say, traditional OLED panels generally output display images on the side corresponding to the anode layer. [0003] The drive circuit in the traditional OLED panel occupies a large area of ​​the pixel unit, therefore, the aperture ratio of the pixel unit is low, which leads to the unsatisfactory display effect of the traditional OLED panel. [0004] In order to solve the above-mentioned technical problems, an improvement solution is to change the traditional OLED panel into a top-light display panel, that is, to output a display image on the side of the OLED panel corresponding to the encapsulation layer. This improvement greatly increases the aperture ratio. [0005] However, in the above improvement scheme, the...
