Abstract: A display panel and a display device are provided. The display panel includes a driving backplate, a plurality of light-emitting diode (LED) chips disposed on a side of the driving backplate, and an adhesive. The adhesive includes a first state and a second state. Viscosity of the adhesive in the second state is less than viscosity of the adhesive in the first state. The driving backplate and the LED chips are fixedly connected to each other by the adhesive in the first state. The adhesive can be converted from the first state into the second state by laser irradiation, and power of the laser is less than 10 w. The driving backplate and the LED chips are attached to each other by the adhesive in the first state, and viscosity of the adhesive in the first state can be reduced by irradiation with a low-power laser.
