Abstract:
Embodiments of the present disclosure provide a display panel and a manufacturing method therefor, and a display device. The side of a driving plate provided with light-emitting diode chips is coated with a photoresist material, and the photoresist material is enabled to cover the plurality of light-emitting diode chips; exposure and etching are performed on the photoresist material to divide the photoresist material into a plurality of photoresist units, and the plurality of photoresist units are in one-to-one correspondence with the plurality of light-emitting diode chips; the photoresist units are shaped so that the outer surface of each photoresist unit is arranged in a protruding arc shape; the photoresist units are configured as units for converging light emitted by the corresponding light-emitting diode chips. According to the display panel manufactured by using the manufacturing method, the photoresist units for converging light can be directly formed on the driving plate, and the light converging effect is improved.
