碩士 === 國立交通大學 === 電子物理系所 === 99 === In this work, we build up the system to manufacture the anodic aluminum oxide (AAO) films with dimension of 5 cm. We also study on the properties of the AAO films as the alignment layer of the liquid crystal (LC) samples. The LC cell using the glass substrate without the conductive film has been demonstrated. Nematic LC molecules can be vertical or high pertilt aligned by controlling the etching time. In addition, we have also used the AAO film with the indium tin oxide (ITO) film or the titanium film underneath as the conductive film. Nematic LC molecules can also be aligned with high pretilt angle. The transmittance of a LC cell can be controlled by applying electric field to it. Finally, we use the polyethylene terephthalate (PET) as the flexible substrate. But the AAO film is too easy to be peeled.
