today’s cyclodextrin:
Conventional LCDs have a drawback of sensitivity to high temperatures. However, mobile phones and in-vehicle applications (such as car navigation systems) and various touch panel instruments with such display(s) are often exposed to harsh conditions. Sumitomo Electric’s polarizing plate has a polarizing element in which a dichroic dye is adsorbed and oriented on a polyvinyl alcohol-based resin layer and a transparent protective film containing a compound having nitroxy radical/ group and cyclodextrin. The model LCD panel well tolerated as high temperatures as 105 Celsius for an extended period of time (240 hours).
