Abstract

A substrate and a preparation method thereof, a display panel, and a display device are provided. The substrate comprises: a base plate that includes a bent area; an insulating layer arranged on the base plate, wherein the insulating layer at the bent area is provided with at least one trench, and the surface of each trench includes at least one concave-convex structure. The concave-convex structures of the substrate can provide enlarged extension area of the surface of the trenches during bending, so that breakage is avoided during bending of members on the trenches, and product yield is increased.

Description

technical field [0001] At least one embodiment of the present disclosure relates to a substrate and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] With the popularization of electronic display products, users also have higher requirements on the appearance and structure of electronic display products, so borderless electronic display products such as display screens are produced in response to demand. A design structure of a borderless display can bend the non-display part of the product to the back of the display, but the bending process may cause some signal lines to break, affecting product yield and increasing production costs. Contents of the invention [0003] At least one embodiment of the present disclosure provides a substrate, including: a base substrate, the base substrate includes a bending area; an insulating layer disposed on the base substrate; wherein, the insulating layer located in the bending area At...
