Abstract
A display substrate and a method thereof, a display panel and a display device are provided. The display substrate includes: a base substrate; and at least one first signal line and a first insulating layer which are disposed on the base substrate; a surface of the first insulating layer away from the base substrate and a surface of the at least one first signal line away from the base substrate are parallel with the base substrate and are substantially located in a continuous flat plane. The first insulating layer which is disposed side by side with the first signal line can improve the surface flatness level of the display substrate and prevent the subsequently formed structures on the display substrate suffering from display defectives due to a too large step.
