Abstract

The invention discloses a display panel, a fabrication method thereof and a display device. The display panel is provided with a display region and a non-display region, wherein the non-display regionis arranged around the display region, a groove structure is arranged at a part, corresponding to the non-display region, of the display panel, and a cooling layer is arranged in at least one part ofthe groove structure. In the display panel disclosed by the embodiment of the invention, the groove structure is arranged at the part, corresponding to the non-display region, of the display panel, the transfer of mechanical stress at the non-display region can be reduced, so that a crack generated by cutting of the display panel is prevented from extending to the display region in the display panel; and by arranging the cooling layer in the groove structure, heat generated by a cutting line is absorbed and dissipated by the cooling layer during cutting of the display panel, separation of aninorganic layer and an organic layer in the display panel caused by factors such as thermal diffusion, thermal expansion and thermal stress generated by the cutting line is prevented, the fabricationyield of the display panel is improved, and the service lifetime of the display panel is prolonged.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] During the manufacturing process of the display panel, it is necessary to cut the motherboard of the display panel by means of laser cutting, so as to obtain multiple display panels separated from each other. [0003] During laser cutting, on the one hand, the mechanical stress generated from the cutting line tends to form cracks at the cutting position, and the cracks tend to extend to the display area inside the display panel, reducing the yield of the display panel. On the other hand, factors such as thermal diffusion, thermal expansion, and thermal stress generated from the cutting line may easily separate the organic layer from the inorganic layer in the display area of ​​the display panel, resulting in panel failure and affecting the life of the display panel.
