The present invention relates to a vertically-laminated microdisplay panel requiring no color filter, the panel comprising: a back wafer, the top surface of which has multiple CMOS electrode pads aligned thereon; multiple LED laminates, each of which includes multiple light emitting units and multiple bonding layers vertically laminated on the back wafer, and which are aligned on the multiple CMOS electrode pads, respectively; and a common electrode formed on the multiple LED laminates, wherein each of the multiple LED laminates emits only a particular color by blocking the light generated from at least one light emitting unit among the multiple light emitting units, or having a short passage formed through at least one light emitting unit among the multiple light emitting units to bypass current so as to prevent the current from being injected into the light emitting unit. La présente invention concerne un panneau de micro-affichage stratifié verticalement et dépourvu de filtre de couleur, le panneau comprenant : une tranche arrière, dont la surface supérieure comprend de multiples plots d'électrodes CMOS alignés sur celle-ci ; de multiples stratifiés de DEL, dont chacun comprend de multiples unités électroluminescentes et de multiples couches de liaison stratifiées verticalement sur la tranche arrière, et qui sont alignées sur les multiples plots d'électrodes CMOS, respectivement ; et une électrode commune formée sur les multiples stratifiés de DEL, chacun des multiples stratifiés de DEL émettant uniquement une couleur particulière en bloquant la lumière générée par au moins une unité électroluminescente parmi les multiples unités électroluminescentes, ou en ayant un court passage formé à travers au moins une unité électroluminescente parmi les multiples unités électroluminescentes pour contourner le courant afin d'empêcher que celui-ci ne soit injecté dans l'unité électroluminescente. 본 발명은 칼라필터가 불필요한 수직 적층형 마이크로디스플레이 패널에 관한 것으로, 상면에 복수의 CMOS 전극 패드가 정렬된 백 웨이퍼, 상기 백 웨이퍼 위에 복수의 발광부와 접합층이 수직 방향으로 적층되며, 복수의 상기 CMOS 전극 패드 상에 각각 정렬되는 복수의 LED 적층체, 및 복수의 상기 LED 적층체 위에 형성된 공통전극을 포함하고, 복수의 상기 LED 적층체 각각은, 복수의 상기 발광부 중 적어도 하나의 상기 발광부에서 생성된 광을 차단시키거나, 복수의 상기 발광부 중 적어도 하나의 상기 발광부에 쇼트(Short) 통로가 형성되어 상기 발광부로 전류가 주입되지 않도록 전류를 우회시킴으로써 특정 색만을 발광하는 것을 특징으로 한다.
