- Abstract
- Transparent colorless polyimide (C. PI) substrate with good optical transparency and high glass transition temperature was developed. To explore performance and process-ability, IZO (indium zinc oxide) pixel electrode was deposited onto the C. PI and the quality of IZO thin films in terms of sheet resistance and transparency was measured. We next fabricated 3-inch C.PI-based liquid crystal display (LCD) clock by mean of sheet-to-sheet freestanding process and investigated its electro-optic characteristics. The resulting LCD showed good electro-optic characteristics; contrast ratio and response time of on/off operation were 826:1 and 12.0 ms, respectively.
