Display apparatus and method of manufacturing the same
First Claim
1. A display apparatus comprising:
- a substrate comprising a first recess and a second recess; and
a first light-emitting diode chip which emits a first color and is mounted on the first recess; and
a second light-emitting diode chip which emits a second color and is mounted on the second recess, the second color being different from the first color,whereineach of the first and second recesses includes a first electrode and a second electrode spaced apart from each other along a thickness direction of the substrate,a shape of each of the first and second light-emitting diode chips corresponds to the arrangement of the first and second electrodes spaced apart from each other of the first and second recesses on which the first and second light-emitting diode chips are mounted, respectively,each of the first and second light-emitting diode chips includes a first electrode pad and a second electrode pad, the first electrode pad and the second electrode pad being arranged along the thickness direction of the substrate, andthe first electrode pad is disposed closer to a bottom surface of the substrate than the second electrode pad.

Abstract
A method of manufacturing a display apparatus includes separating a light-emitting diode (“LED”) chip from a base substrate; disposing the separated light-emitting diode chip in a solution; disposing a substrate including a first electrode thereon, in the solution; with the separated light-emitting diode chip and the substrate including the first electrode thereon in the solution, applying a negative voltage to the substrate to attract the separated light-emitting diode chip to the first electrode on the substrate; mounting the light-emitting diode chip attracted to the first electrode, on the first electrode; and removing the substrate with the light-emitting diode chip mounted on the first electrode from the solution and drying the removed substrate, to form the display apparatus.
