Abstract

The invention discloses a display substrate, a manufacturing method thereof, and a display device, and relates to the field of display technology, in order to solve the problems in the OLED display device that the preparation process of a pixel defining layer is complicated and the materials used are likely to pollute the environment. The display substrate includes: a base substrate; a thin film transistor array layer arranged on the base substrate, the thin film transistor array layer defines a plurality of groove structures on the side facing away from the base substrate; The insulating film layer on the side of the thin film transistor array layer facing away from the base substrate, the insulating film layer defines a plurality of pixel regions in the plurality of groove structures, and the pixel regions are connected to the plurality of pixel regions. The groove structures are in one-to-one correspondence; the plurality of light-emitting units arranged in the plurality of pixel regions are in one-to-one correspondence. The display substrate provided by the invention is used for display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technologies, organic light-emitting diode (English: Organic Light-Emitting Diode, hereinafter referred to as OLED) display devices have gradually attracted widespread attention due to their advantages such as self-luminescence, wide viewing angle, and high contrast. The structure of this OLED display device mainly includes: a base substrate, a thin film transistor array layer formed on the base substrate, and a light emitting unit formed on the thin film transistor array layer; since the light emitting unit is the same as the pixel unit included in the OLED display device One-to-one correspondence, and the light-emitting layer included in the light-emitting unit is generally realized by inkjet printing technology. Therefore, in orde...
