Abstract

A fabrication method of a display panel and a display panel, and a display device are provided. The display panel is divided into a display region and a non-display region and comprises a first substrate, and the non-display region of the first substrate includes an IC attaching region. The fabrication method comprises a thinning process. The thinning process includes: 1) forming a barrier layer insoluble to a thinning fluid in a region of a first surface of the first substrate of the display panel corresponding to the IC attaching region; 2) thinning the display panel by adopting the thinning fluid such that a thickness of the IC attaching region of the first substrate is greater than a thickness of the display region of the first substrate; and 3) removing the barrier layer.
