The invention discloses a transparent display device and a manufacturing method thereof. The transparent display device comprises a substrate and organic electroluminescence devices, wherein the substrate comprises a plurality of pixel regions and photic regions positioned among the pixel regions; the organic electroluminescence devices are arranged on the substrate, and are positioned on the pixel regions of the substrate; the organic electroluminescence devices comprise thin film transistors, pixel electrodes, luminescent layers, first opposite electrodes and second opposite electrodes; the thin film transistors are arranged on the pixel regions of the substrate; the pixel electrodes are arranged on the pixel regions of the substrate, and are electrically connected with the thin film transistors; the luminescent layers are arranged on the pixel electrodes; the first opposite electrodes are arranged on the pixel regions of the substrate, and are positioned above the thin film transistors and the luminescent layers; the second opposite electrodes are arranged above the pixel regions and the photic regions, the second opposite electrodes in the pixel regions are positioned above the first opposite electrodes, and the second opposite electrodes are used for electrically connecting the first opposite electrodes. According to the transparent display device disclosed by the invention, the light transmission and transparency of the transparent display device can be greatly improved.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a transparent display. Background technique [0002] Compared with many display panels, OLED panels have become the only carrier for the development of transparent display technology due to their many advantages such as active light emission, high contrast, no viewing angle limitation, and unique device structure. [0003] Existing transparent displays are roughly divided into two structures, one is a bottom emission structure, and the other is a top emission structure. Generally, whether in a transparent display with a bottom-emitting structure or a top-emitting structure, an ordinary mask (not a high-precision mask) is generally used for full-screen cathode evaporation. See figure 1 , which shows a schematic view of a vertical cross-sectional structure of a transparent display in the prior art. Such as figure 1 As shown, taking a transparent display with a top-emission ...

AI Technical Summary

Problems solved by technology

It can be seen that the light transmittance of the transparent display screen in the prior art is relatively poor, and further, its display effect will be seriously affected.
