Title:
DISPLAY DEVICE USING SEMICONDUCTOR LIGHT EMITTING DIODE
Document Type and Number:
WIPO Patent Application WO/2017/034268
Kind Code:
A1
Abstract:
The present invention relates to a display device and, in particular, to a display device using a semiconductor light emitting diode. A display device according to the present invention comprises a substrate having a plurality of metal pads; and a plurality of semiconductor light emitting diodes electrically connected to the metal pads through self-assembly. The present invention is characterized in that: the semiconductor light emitting diodes respectively include a conductive semiconductor layer, a conductive electrode formed on one surface of the conductive semiconductor layer, and a passivation layer enclosing the semiconductor light emitting diode and provided with a through hole for exposing the conductive electrode; one end portion of the semiconductor light emitting diodes is divided into a first portion in which the conductive electrode is exposed, and a second portion in which the passivation layer is exposed; and the maximum width of the metal pad is set to a range of the width to twice the width of the second portion.
