Amorphous in-plane switching twisted nematic liquid crystal displays fabricated without rubbing process show a wide viewing angle and fast response characteristics

Excellent electrooptical (EO) characteristics of an amorphous in-plane switching twisted nematic liquid crystal display, which is fabricated without the conventional rubbing treatment, are demonstrated. A wide and uniform viewing angle characteristic without showing gray scale inversion or color shift can be realized by the multidomain alignment, which is called 'amorphous alignment'. The response time was much less than 17 ms and relaxation time was as fast as 10 ins. The device may contribute not only to the simplification of the production process but also to significant improvement of the response time, compared with the conventional rubbed liquid crystal display.
