These microgrooved polymer surfaces are assembled to form liquid crystal cells. The anchoring energy of these microgrooved polymer surfaces will be determined, as well as the pretilt angle of liquid crystal molecules. The effects of surface topology and surface polarity on the alignment of liquid crystal molecules will be carefully examined. The surface topology can be manipulated by generating different microgroove periods and depths. The surface polarity of the polymer surface is manipulated by using different polymers, and is identified by the advancing contact angle of water. Note that the soft embossing process is simple and without the disadvantages of rubbing process, which creates debris and electrostatic charges. This novel process is highly potential to replace the rubbing process. In this proposal, we will validate whether this soft embossing method is an alternative to the rubbing process.液晶配向膜軟壓印預傾角前進角liquid crystalalignment filmsoft embossingpretilt angleadvancing contact angle
