Title:
DISPLAY DEVICE USING LIGHT-EMITTING ELEMENT AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/243736
Kind Code:
A1
Abstract:
The present invention can be applied to technical fields relating to display devices, and relates to a display device using, for example, a micro light-emitting diode (LED) and a manufacturing method therefor. The present invention, which is a display device using a semiconductor light-emitting element, may comprise: a wiring substrate; first electrodes defining unit sub-pixel regions and arranged on the wiring substrate; light-emitting elements having first type electrodes disposed on the first electrodes; a plurality of conductive balls electrically connecting the first type electrodes of the light-emitting elements with the first electrodes; and conductive adhesive parts located on the conductive balls to fix the conductive balls to the first electrodes and/or to the first type electrodes.
