Abstract

Embodiments of the present invention provide a display panel and a display device. The display panel includes: a flexible circuit board for driving an array substrate, having a main body area, a binding area and a transition area, the transition area is located between the main body area and the binding area, and the flexible circuit board The board includes a stacked substrate, a wiring layer, and an insulating layer. The wiring layer includes metal wires; wherein, the metal wires located in the bonding area are exposed from the insulating layer and overlapped with the driving array substrate for bonding connection. The insulating layer includes a first For the insulating part and the second insulating part, at least part of the first insulating part is located in the main body area, and the second insulating part is located in the transition area, and the average thickness of the first insulating part is greater than the average thickness of the second insulating part. The embodiments of the present invention can increase the service life of the metal wires and improve the yield of the display panel.

Description

technical field [0001] The invention relates to the technical field of display equipment, in particular to a display panel and a display device. Background technology [0002] With the continuous updating of the display, the small-size panel is gradually developing towards light and thin, high screen proportion, ultra narrow border and even no border. In order to increase the screen share of the display device, the metal wire is usually bent to the back of the display device. The display panel usually includes a display area and a non display area located on the peripheral side of the display area. The wiring layer of the non display area is used to arrange and bind flexible circuits. The wiring layer is overlapped on the substrate of the display area. In order to avoid the insulation layer of the wiring layer being overlapped on the substrate, there is a preset distance between the insulation layer and the substrate, which will cause the metal layer of the wiring layer not to be...
