The development of high-productivity microLED ( μ -LED) pixel panels is crucial as a key technology for next-generation displays. To provide a fundamental approach to this end, in this study, multicolor (red, green, blue, and yellow; RGBY) nanocolumn (NC) μ -LED pixels with 5 × 5 μ m 2 emission windows were monolithically integrated to exhibit electroluminescence spectra with peak wavelengths of 478, 512, 559, and 647 nm, respectively. The NC μ -LED pixels, which were two-dimensionally arranged with a 10 μ m period, were individually driven by the matrix wiring p- and n-electrodes, exhibiting a μ -LED pixel panel arrangement.
