Abstract:
Provided are a display panel and a preparation method therefor, and a display device. The display panel comprises a base substrate (10). A peripheral region of the base substrate (10) is provided with an insulating layer (9). At least one package dam (110) is provided at the side of the insulating layer (9) distant from the base substrate (10). The package dam (110) is located in the peripheral region of the base substrate (10), and surrounds a display region. The insulating layer (9) is provided with at least one groove (131). The groove (131) surrounds the display region. The projection of the at least one groove (131) in the base substrate (10) is located in the projection of the package dam (110) in the base substrate (10). The groove (131) can slow down or prevent a crack from extending to the display region, and improves the package effect. At the same time, the groove (131) is provided below the package dam, so that the width of the peripheral region can be shortened, and the screen-to-body ratio is increased.
