Abstract

본 발명은 액정표시소자의 배향막 형성방법에 관한 것으로서, 보다 상세하게는 폴리이미드가 인쇄된 배향막위에 중합 가능한 액정물질을 이용하여 단량체의 분자레벨로 쌓아 수층의 초박막으로된 유기분자층을 누적함으로써 러빙공정 없이도 액정 분자들을 배향시킬 수 있도록 한 비접촉방식의 배향막 형성방법에 관한 것이다.The present invention relates to a method of forming an alignment layer of a liquid crystal display device, and more particularly, to rubbing by stacking an organic molecular layer of several ultra-thin layers by stacking at the molecular level of a monomer using a liquid crystal material that can be polymerized on an alignment layer on which polyimide is printed. The present invention relates to a method of forming a non-contact alignment layer that can align liquid crystal molecules without a process.

특징적인 구성으로는 유리기판의 투명전극상에 배향제로 사용되는 폴리이미드를 프린트기법으로 코팅하여 PI배향막을 형성한 것에 있어서, 액정분자의 배향성을 부여하기 위해 진동이 없는 수조위에 중합가능한 액정물을 분산시켜 단일 분자결정층(단량층)을 형성하여 상기의 PI배향막 위에 누적시킨 후 누적된 단량층에 UV광을 조사하여 중합시켜 중합배향막을 형성하거나 액정 분자의 배향성을 부여하기 위해 진동이 없는 수조위에 중합가능한 액정 물질을 분산시켜 단일 분자결정층(단량층)을 형성하여 UV광을 조사하여 중합시킨 후, 상기 중합된 단량층을 PI배향막 위에 누적시켜 중합배향막을 형성함에 있다.As a characteristic constitution, a polyimide used as an alignment agent on a transparent electrode of a glass substrate was formed by a printing technique to form a PI alignment layer. Disperse to form a single molecular crystal layer (monolayer) and accumulate on the PI alignment layer and then irradiate and polymerize the accumulated monolayer by UV light to form a polymerization alignment layer or a vibration free tank to impart orientation of liquid crystal molecules. The polymerizable liquid crystal material is dispersed thereon to form a single molecular crystal layer (monolayer), irradiated with UV light to polymerize, and the polymerized monolayer is accumulated on the PI alignment layer to form a polymerization alignment layer.
