Abstract

The invention discloses an organic electroluminescent transistor array substrate, a manufacturing method thereof, and a display device, and relates to the field of display technology. The organic electroluminescent transistor array substrate includes: a substrate, and a gate layer, a gate insulating layer, a semiconductor layer, a source layer, a pixel defining layer, an organic electroluminescent layer and a drain layer formed sequentially along the thickness direction of the substrate, The gate layer is formed on the substrate; wherein, the source layer includes several source units corresponding to the sub-pixel units, and the pixel defining layer includes several pixel defining units corresponding to the source units; and each source unit is embedded in the corresponding In the pixel defining units; the organic electroluminescent layer is formed on the surface of each pixel defining unit and the surface of the exposed portion of the semiconductor layer between adjacent source units.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence transistor array substrate, a manufacturing method thereof, and a display device. Background technique [0002] An organic electroluminescent display is a current-type light-emitting device that uses organic electroluminescent materials as illuminants. According to the classification of driving methods, organic electroluminescent displays can be divided into passively driven organic electroluminescent displays and active driven organic electroluminescent displays; among them, the driving voltage of active driven organic electroluminescent displays is low, suitable for For high-definition and large-size display, but its manufacturing process is complicated and the production cost is high. In order to solve the problem of complex manufacturing process and high production cost of active-driven organic electroluminescent displays, researchers combined...
