Miniature light-emitting diode substrates, miniature light-emitting diode displays, and XR glasses

Abstract

The micro-light-emitting diode substrate (100) includes: a micro-light-emitting diode array, on an n-type GaN layer (11), each pixel having a red-emitting AlGaInN micro-light-emitting diode (30), a green-emitting AlGaInN micro-light-emitting diode (40), and a blue-emitting AlGaInN micro-light-emitting diode (50); and a transparent insulating film (21) on the micro-light-emitting diode array. It is provided with: a p-side electrode extraction electrode (22), which is connected to each of the plurality of p-side electrodes (19) provided for each diode through contact holes (21a) in the transparent insulating film; and an n-side electrode extraction electrode, which is connected to the n-side electrodes through other contact holes. P-side wiring (24-26) is provided along the plurality of p-side electrodes of each diode.
