Abstract
The disclosure provides a manufacturing method of a mass transfer device. The manufacturing method includes the following. A transfer substrate coated with an adhesive layer is provided. A light emitting diode is transferred from an original substrate to the transfer substrate. A supporting structure is etched on the light emitting diode, where the supporting structure includes at least two supporting columns extending from the transfer substrate, and ends of the at least two supporting columns away from the transfer substrate are connected with the light emitting diode, so that the light emitting diode is arranged separately from the transfer substrate. The adhesive layer is removed, so that the light emitting diode is fixed on the transfer substrate only through the supporting structure. In addition, the disclosure also provides a mass transfer device and display equipment.
