Abstract

The invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a display area and a frame area; the frame area comprises a first circuit area, a wiring area and a second circuit area, and the frame area comprises a frame structure layer and a first flat layer which are arranged on a substrate; the frame structure layer of the first circuit area comprises a first gate drive circuit, the frame structure layer of the second circuit area comprises a second gate drive circuit, the frame structure layer of the wiring area comprises at least one output signal line, and the output signal line extends towards the direction of the display area; the first flat layer is provided with at least one exhaust groove, and the orthographic projection of the exhaust groove on the substrate is not overlapped with the orthographic projection of the output signal line on the substrate. The orthographic projection of the exhaust groove on the substrate and the orthographic projection of the output signal line on the substrate are not overlapped, so that the coating effect of the first flat layer on the signal line is ensured, and defects such as short circuit or signal crosstalk are effectively avoided.

Description

technical field [0001] The present disclosure relates to but is not limited to the field of display technology, especially to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED for short) and Quantum-dot Light Emitting Diodes (QLED for short) are active light-emitting display devices with self-illumination, wide viewing angle, high contrast, low power consumption, high The advantages of response speed, thinness, bendability and low cost. With the continuous development of display technology, a display device using OLED or QLED as a light-emitting device and signal-controlled by a Thin Film Transistor (TFT for short) has become a mainstream product in the display field. [0003] The inventors of the present application have found through research that existing display devices have problems such as short circuit or signal crosstalk. Contents of the invention [0004] The following is a...
