US 2020/0395345 A1 · METHOD FOR MANUFACTURING DISPLAY DEVICE AND SUBSTRATE FOR MANUFACTURING DISPLAY DEVICE

Abstract

The present disclosure relates to an assembly substrate used for a display device manufacturing method in which semiconductor light-emitting diodes are placed on the assembly substrate at preset positions using electric field and magnetic field. Specifically, the assembly substrate includes a base portion, a plurality of assembly electrodes extending in one direction and disposed on the base portion, a dielectric layer stacked on the base portion to cover the assembly electrodes, a barrier wall formed on the base portion and having a plurality of recesses for guiding the semiconductor light-emitting diodes to the preset positions, and a metal shielding layer formed on the base portion, wherein the metal shielding layer overlaps the barrier wall so that an electric field formed between the assembly electrodes is shielded.

A method for manufacturing a display device, the method comprising:

feeding an assembly substrate having a plurality of assembly electrodes to an assembly site, and putting semiconductor light-emitting diodes into a fluid chamber;
applying a magnetic force to the semiconductor light-emitting diodes so that the semiconductor light-emitting diodes move in one direction within the fluid chamber;
applying a voltage to each of the assembly electrodes such that the semiconductor light-emitting diodes are guided onto preset positions by an electric field formed between the assembly electrodes while the semiconductor light-emitting diodes move along the one direction;
and
transferring the semiconductor light-emitting diodes placed on the assembly substrate onto a wiring substrate,
wherein the assembly substrate is provided with a metal shielding layer disposed thereon for shielding an electric field so as to prevent the electric field from being formed in areas except for the preset positions.
