Abstract

본 발명은 전계방출소자등의 평판표시소자에 형광층을 형성하는 신규한 방법을 개시한다.The present invention discloses a novel method for forming a fluorescent layer on a flat panel display element such as a field emission device.

전계방출소자나 액정표시소자의 투명전극을 형광층과 부착성이 나빠 형광층이 들뜨거나 분리되므로 사진식각법의 적용이 불가능하고, 이에 따라 칼라 전계방출소자의 구현등이 불가능하였다.It is impossible to apply the photolithography method because the field emission device or the transparent electrode of the liquid crystal display device has poor adhesion with the fluorescent layer and the fluorescent layer is floated or separated.

본 발명에서는 형광체가 포함되지 않은 버퍼용액내에 기판을 투입하고 그 상부에서 형광체가 포함된 침전용액을 주입하여, 분급된 형광층을 형성함으로써 사진식각법에 의해 패터닝이 가능하고 발광휘도도 향상된다.In the present invention, a substrate is put in a buffer solution not containing a phosphor, and a precipitating solution containing a phosphor is injected thereon to form a classified fluorescent layer, whereby patterning is possible by photolithography and luminous brightness is improved.
