Document Type and Number:
WIPO Patent Application WO/2023/132394
Kind Code:
A1
Abstract:
The present invention is applicable to display device-related technical fields and relates to, for example, a display device using a micro light-emitting diode (LED). The present invention may comprise: a substrate; partition walls which are arranged on the substrate to define a plurality of hexagonal unit pixel areas forming a honeycomb shape; semiconductor light-emitting elements each of which is disposed in each of the unit pixel areas to form each unit pixel; color conversion layers which convert light emitted from the semiconductor light-emitting elements into colors corresponding to the respective unit pixel areas; a porous layer which is disposed on the partition walls and in which a plurality of through-holes are formed; and color filter layers which are disposed on the porous layer.
