Abstract
A display panel and a display device are provided. The display panel includes a substrate including a first flexible base, an inorganic insulating layer, a driving circuit layer, a light emitting layer including a common layer, and an encapsulation layer including at least one inorganic layer. A first undercut structure is defined on a peripheral area of the display panel, and the common layer includes a first portion and a second portion disconnected by the first undercut structure. At least one inorganic layer covers the first portion and does not exceed an end of the common layer away from a light emitting area.
Claims20
A display panel defined with a light-emitting area and a peripheral area positioned on at least one side of the light-emitting area, wherein the display panel comprises:
- a substrate comprising a first flexible base;
- an inorganic insulating layer disposed on a side of the substrate;
- a driving circuit layer disposed on a side of the inorganic insulating layer away from the substrate;
- a light-emitting layer disposed on a side of the driving circuit layer away from the inorganic insulating layer, wherein the light-emitting layer comprises a common layer;
- and
- an encapsulation layer disposed on a side of the light-emitting layer away from the driving circuit layer, wherein the encapsulation layer comprises at least one inorganic layer;
- wherein the peripheral area is defined with a groove penetrating the inorganic insulating layer and the first flexible base, wherein a sidewall of the groove is defined with a first undercut structure, wherein the common layer comprises a first portion and a second portion, the first portion is positioned at the light-emitting area and the peripheral area, the second portion is at least partially positioned at the groove, and the first portion and the second portion are disconnected by the first undercut structure, and wherein the at least one inorganic layer covers an end of the first portion away from the light-emitting area, and an end of the at least one inorganic layer away from the light-emitting area does not exceed an end of the common layer away from the light-emitting area.
