Document Type and Number:
WIPO Patent Application WO/2022/217638
Kind Code:
A1
Abstract:
The present application provides a display panel and a preparation method therefor, and a display device. According to the display panel, by providing an anti-cracking structure in a chamfer between a driving circuit layer and a substrate, the anti-cracking structure is in contact with a packaging layer, then the anti-cracking structure can reduce the angle between a contact plane of the anti-cracking structure and the packaging layer and a plane where a light emitting layer is located, such that the packaging layer is configured to be flat, and thus the risk of breakage of the packaging layer is reduced and a display panel failure is avoided.
