Abstract

The invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a plurality of first electrodesthe first electrodes being located on a flat layer of a driving back plate and provided with flat middle portions, and a spacing groove exposing the flat surface of the flat layer being formed between every two adjacent first electrodes; electric leakage cut-off layers located on the first electrode layers and located between every two adjacent first electrodes, the electric leakage cut-off layers being provided with cut-off grooves whichcorrespond to the spacing grooves and expose the flat surface of the flat layer, and the electric leakage cut-off layers being in lap joint with the surface of the middle part on at least one side; alight-emitting function layer, located on the side, deviating from the driving backboard, of the electric leakage cut-off layer and the first electrode layer. According to the display substrate, whenone pixel emits light, current cannot be transmitted to other adjacent pixels through the hole injection layer, the phenomena of transverse electric leakage and crosstalk are avoided, and the qualityand the color purity of a display are improved.

Description

technical field [0001] The present disclosure relates to but not limited to the field of display technology, and specifically relates to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, silicon-based organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) microdisplays are often used as near-eye displays in the field of virtual reality (Virtual Reality, VR) / augmented reality (Augmented Reality, AR). Silicon-based semiconductor technology is mature and highly integrated, which can realize ultra-high PPI display. [0003] In use, it is found that silicon-based OLED micro-displays have cross-color or cross-talk phenomenon, which affects the color gamut of the display and reduces the quality and color purity of the display. Contents of the invention [0004] The purpose of the embodiments of the present disclosure is to provide a display substrate, a manufacturing method thereof, and ...
