Title:
DISPLAY DEVICE USING MICRO-LEDS AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/060595
Kind Code:
A1
Abstract:
The present specification provides a display device using semiconductor light-emitting diodes which are self-assembled in fluid, and a method for manufacturing same. Specifically, the semiconductor light-emitting diode comprises: a first-conductive-type electrode layer and a second-conductive-type electrode layer; a first-conductive-type semiconductor layer electrically connected to the first-conductive-type electrode layer; an active layer provided on the first-conductive-type semiconductor layer; and a second-conductive-type semiconductor layer provided on the active layer and electrically connected to the second-conductive-type electrode layer, wherein one surface of the second-conductive-type semiconductor layer comprises a mesa structure formed by etching a portion of the one surface, and the second-conductive-type electrode layer is provided on the one surface comprising the mesa structure of the second-conductive-type semiconductor layer.
