Abstract

The invention provides a display substrate, a preparation method thereof, and a display device, and relates to the technical field of display devices. The display substrate comprises a driving structure layer and a light-emitting structure layer which are arranged on a base in an overlapped mode, the driving structure layer comprises a thin film transistor, the light-emitting structure layer comprises a first electrode and a shielding layer used for shielding ultraviolet light (UV), and the front projection of the shielding layer on the base contains the front projection of the thin film transistor on the base. According to the display substrate in the embodiment of the invention, the problem that in the preparation process of the display substrate, a UV mask plate is adopted, and consequently, the production cost is increased can be solved.

Description

technical field [0001] The present application relates to the technical field of display devices, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diodes (OLEDs) have gradually developed in the fields of display and lighting technologies in recent years, especially in the field of display, because of their advantages such as high response, high contrast, and flexibility, they have broad application prospects. However, because OLED devices will be corroded and damaged under the action of water vapor and oxygen, it is particularly important to choose a better packaging method for OLED devices. At present, the thin-film encapsulation method for the display substrate is usually to cover the OLED device with a thin-film encapsulation structure stacked with inorganic layers and organic layers, so as to achieve the purpose of blocking water and oxygen. Among them, the inorganic layer is...
