초록
We investigated the effect of polarity of polyimide(PI) film in amorphous (a) - twisted nematic (TN) - liquid crystal display(LCD) for response time and viewing angle. We found that the domain size of a-TN-LCD on PI film with high polarity is smaller then medium polarity. It is considered that the electro-optical characteristics are strongly dependent on this domain in a-TN-LCD. We observed the response time of a-TN-LCD on PI film with high polarity is slow as comparing to PI film with medium polarity. We suggest that the response time of a-TN-LCD is attributed surface effect between the LCs and the substrates.
