Abstract

액정표시소자의 단차의 제로(zero)화 실현에 관한 기술인 본 발명은 표시의 고품위화에 대한 사용자의 요구에 부응하도록 ITO 전극과 배향막의 엄격한 평활화를 실현시켜 소자의 해상도를 향상시키고, 나아가서는 단차 극복을 위한 평활막으로서 절연특성을 갖는 배향막과 동일한 재료를 사용하되, 이 용액내에 네가티브 감광제(negative sensitizer)를 소량 첨가시켜 패터닝이 가능한 용액으로 사용하여 배향막과의 밀착성을 향상시킴으로써, 액정표시소자가 최대의 연구과제중의 하나로 삼고 있는 고해상도 및 표시의 고품위화에 매우 유용하게 적용될 수 있다.The present invention, which is a technique for realizing zero step difference of the liquid crystal display device, realizes strict smoothing of the ITO electrode and the alignment layer to meet the user's demand for high quality display, thereby improving the resolution of the device, As a smoothing film for overcoming, the same material as that of the alignment film having insulating properties is used, but a small amount of negative sensitizer is added to this solution to be used as a patternable solution to improve adhesion to the alignment film. It is very useful for high resolution and high quality display.
