Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display area and a frame area. The frame area comprises an outer pin area, and the outer pin area comprises a substrate, a metal wire layer and a first thin film layer which are stacked in sequence; the first film layer covers the metal wire layer; and at least one groove is formed in oneside, far away from the metal wire layer, of the first thin film layer. According to the technical scheme provided by the embodiment of the invention, the first thin film layer is arranged on the metal wire layer in the outer pin area, and at least one groove is formed in the first thin film layer, so that residual stress in the bending process is reduced, the situation that each film layer cracksor fractures when the outer pin area is bent can be avoided, and the bending resistance of the whole outer pin area is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] With the development of science and technology, the requirements for the display panel are gradually increasing. In order to have a larger display area, the display panel is gradually developing towards a higher screen-to-body ratio. [0003] In order to achieve a display panel with a high screen-to-body ratio, the frame area of ​​the display panel will be reduced as much as possible to achieve a narrow frame or even no frame. In order to achieve a high screen-to-body ratio and a variety of shapes displayed on the display panel, it is necessary to bend the outer lead area to reduce the non-display area. However, the existing outer lead area structure has poor bending resistance, and the metal traces in the outer lead area are prone to breakage when bent together with the substrate, which affects...
