The effect of the polymer polarity of three types of polyimide (PI) on transcription-aligned twisted nematic liquid crystal display (TN-LCD) surfaces has been investigated. Monodomain alignment of the NLC was obtained in cells fabricated by the transcription alingment method on PI surfaces with medium polarity; the LC alignment is attributed to the polarity of the polymer. The threshold voltage of transcription-aligned TN-LCDs was found to decrease with increasing polarity of the polymer. The threshold voltage of a transcription-aligned TN-LCD on PI surfaces with high polarity was almost the same as that of a rubbingaligned TN-LCD. The response time of transcription-aligned TN-LCDs decreased with increasing polymer polarity. The decay time of transcription-aligned TN-LCDs was long in comparison with rubbing-aligned TN-LCDs; this is attributed to the weak anchoring strength between the LC molecules and the PI surface. |
