Abstract
A bendable display panel and a fabricating method thereof are disclosed, including: providing the flexible substrate and the inorganic film layer formed on the flexible substrate, the inorganic film layer includes a deep hole region disposed in a bending area; dry etching the deep hole region to form a deep hole having a slope, and a bottom of the deep hole is located on the flexible substrate; filling the deep hole with an organic material to form an organic film layer; and forming a metal wiring layer on the inorganic film layer and the organic film layer. In the method, a deep hole having a slope is formed by gas dry etching. The etching method can control the slope to improve the climbing ability of the metal wiring, and reduce or avoid the loss of electrical signal caused by disconnection of the metal wiring, thereby improving the display panel quality.
