Abstract

The invention provides a flexible display panel and a display device, which are used for solving the problem that an inorganic film layer affects the performance reliability of the display panel and improving the performance reliability of the display panel. The flexible display panel includes a flexible substrate; an inorganic film layer located on the flexible substrate and comprising a first portion and a second portion, the first portion and the second portion being connected, the first portion having a first thickness T1, the second portion having a second thickness T2, and T1<T2; the first portion includes at least one first sub-portion and at least one second sub-portion, the first sub-portion and the second sub-portion are connected, and the joint of the first sub-portion and the second sub-portion is a dividing line between the two, and the dividing line extends in a first direction. In the first direction, the end part of the first sub-portion coincides with the end part of the second sub-portion, and the dimension of the second sub-portion in the first direction gradually changes from the dividing line in a direction away from the first sub-portion.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] In the process of manufacturing display panels, the display panel is usually produced by stacking film layers. Based on the consideration of factors such as the sealing and thickness of the display panel, the display panel usually includes film layers formed of inorganic materials. The film layer formed by organic materials and the film layer formed by inorganic materials have poor stress resistance and are prone to cracks under the action of stress, which brings great hidden dangers to the performance reliability of the display panel. Therefore, how to solve the problems caused by inorganic materials The problem that the film layer affects the performance reliability of the display panel needs to be solved urgently. Contents of the invention [0003] In view of this, embodiments of the prese...
