Abstract

The embodiment of the invention discloses a display panel and a display device. The display device in the embodiment of the invention comprises a pixel array and a flexible substrate, and the flexiblesubstrate comprises a first area and a second area which are arranged at the bottom of the pixel array, and a bending area located between the first area and the second area, wherein a hollowed-out groove is formed in the flexible substrate at a position corresponding to the bending region; through the hollowed-out grooves, the problem that when the panel is bent, stress concentration is caused by attachment deformation between the laminated layers, the laminated layers of the display panel are prone to breakage or stripping, and consequently display of the display panel is poor is solved. Inone embodiment, a layer of ultraviolet photosensitive adhesive is coated in the hollowed-out groove, so an isolation effect is achieved, and a product can be protected from external damage.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the modern communication industry, the market demand for mobile phones, TVs, tablets, notebooks, digital cameras and other products is increasing, and various display devices are also developing towards curved surface display and multi-sided display. [0003] In the manufacture of flexible display panels, CG (cover glass, cover glass) bonding process is required. The traditional bonding process is developing in the direction of curved surface bonding process. However, in the process of curved surface bonding of existing display panels, refer to figure 1 and figure 2 As shown, the stacked layers including the flexible substrate 800, the adhesive layer 400, and the pixel array 500 at the corners are relatively thick, and the bonding deformation between the stacked layers at the bending position leads ...
