Abstract

The present disclosure provides a transparent OLED display and a manufacturing method thereof. The manufacturing method of the transparent OLED display forms an active layer and a first storage capacitor electrode in the same process. The first storage capacitor electrode is made of the transparent metal oxide semiconductor material. A second storage capacitor electrode is manufactured by two photolithography processes so the second storage capacitor electrode is made of only a transparent conductive oxide material. A storage capacitor region where the first storage capacitor electrode and the second storage capacitor electrode are located is a transparent region. Thus, light transmittance and transparent display effect of the transparent OLED display is enhanced. Further, a terminal located in a peripheral region is formed and only made of the transparent conductive oxide material to prevent it from being corroded by water and oxygen. It enhances service life of the transparent OLED display.
