(ZH) 电致发光显示基板及其制备方法、电致发光显示装置
Abstract
(EN)
The invention provides an electroluminescent display substrate and a preparation method thereof, and an electroluminescent display device. The display substrate comprises a substrate, a thin film transistor arranged on the substrate, a display light emitting element located on one side, away from the substrate, of the thin film transistor, an inorganic material layer located between the thin filmtransistor and the display light emitting element, a packaging structure arranged on the substrate for covering the display light emitting element, an opening which at least penetrates through the packaging structure, at least one isolation column arranged on the substrate, and a coating layer arranged on the substrate for covering at least one isolation column, wherein at least one isolation column surrounds the opening; the orthographic projection of the inorganic material layer on the substrate is at least partially overlapped with the orthographic projection of the thin film transistor onthe substrate; the orthographic projection of the at least one isolation column on the substrate falls into the orthographic projection of the coating layer on the substrate; and the coating layer andthe inorganic material layer are positioned on the same layer.
