Abstract
A method for manufacturing micro light-emitting diode chips includes the steps of: providing a to-be-divided light-emitting component, which includes a metal substrate and a plurality of micro light-emitting diode dies disposed on the metal substrate to permit the metal substrate to define a to-be-etched region among the micro light-emitting diode dies; and etching the metal substrate to remove the to-be-etched region so as to divide the light-emitting component into a plurality of the micro light-emitting diode chips.
