Abstract (2. Language): 
In this study, the photolithographic technique for molecular alignment on the polyimide thin film was studied. The liquid crystal alignment properties of the photolithographic application were presented by the polyimide thin films and observed on photoaligned polyimide film by a surface profiler. This method was provided by the micro-patterning process that includes spin-coating, UV exposing and wet chemical etching. The cell gap of liquid crystal displays was measured by the rotational scanning interferometer unit. The results of the photolithographic method and the molecular alignment proper¬ties of the nematic liquid crystal cell were observed by applying an electric field with the micro-patterning interval of approximately 100 microns. These results will be developed gradually in further studies for nano-scale applications.

Fotolitografik uygulamanın sıvı kristal yonelim ozellikleri polyimide ince filmlerle sunuldu ve yüzey profilleriyle foto-yonelmiş ince polyimide film üzerinde güzlendi. Mikro kanal oluşturmayla sağlanan bu metot, spin kaplama, UV pozlama ve kimyasal aşındırmayı icerir. Sıvı kristal gorüntüleyicinin hücre kalınlıgı dünel tarama interferomet-rik üniteyle olçüldü. Fotolitografik metodun sonucları ve nematik sıvı kristal hücrenin moleküler yonelim ozellikleri 100 mikronluk aralıkla oluşan mikro desenler yoluyla elektrik alan uygulanmasıyla gozlendi. Bu metodun ileriki calışmalarda nano olçekte geliştirilmesi umulmaktadır.
