The invention provides a display panel and a display device. The display panel comprises a flexible circuit board, a touch layer, a cover plate and an auxiliary transparent layer arranged close to thecover plate, wherein the flexible circuit board is connected with the touch layer; first sealing glue is arranged at the junction between the touch layer and the flexible circuit board; the first sealing glue is positioned on one side, facing the cover plate, of the flexible circuit board; the distance between the side, facing the cover plate, of the auxiliary transparent layer and the cover plate is not larger than the distance between the side, facing the cover plate, of the first sealing glue and the cover plate. During mounting of the cover plate, the cover plate comes into contact with the auxiliary transparent layer firstly, so that cracks between the first sealing glue and the touch layer as well as between the first sealing glue and the flexible circuit board caused by the stresson the first sealing glue can be avoided.
Description
technical field [0001] The present invention relates to the technical field of display devices, and in particular, to a display panel and a display device. Background technique [0002] With the gradual development of display device technology, flexible display panels have been gradually applied to wearable devices, such as smart watches and wrist phones. [0003] In the prior art, a display panel includes a flexible circuit board, a cover plate, a polarizer, a touch layer, and a display layer that are stacked in sequence; one end of the flexible circuit board is connected to a control device, and the other end of the flexible circuit board is connected to the touch layer, In order to realize the touch control of the display device. When generated, the display layer, touch layer and polarizer are first formed, and then the flexible circuit board is connected to the touch layer; in order to avoid contact between the outside air and the touch layer, a solid sealant is often a...
