Abstract
The glazed areas in automobiles are increasing in size.' As the glass area grows larger, we need better solar control to maintain comfort for the occupants and to reduce the need for larger air, conditioners. For solar control, we need to filter out infrared energy that causes heat buildup,2 control visible light and block out ultraviolet energy. To control visible light, devices using photochromism, liquid crystal, thermochromism and electrochrornism have been studied.3 We developed a transmissive type of electrochromic (EC) device (for antiglare purpose) by using cathodically coloring tungsten oxide (W03) and anodically color- ing Prussian blue (PB). Recently a practical antiglare mirror for automotive use has been put on the market,'" but large scale EC device for automobiles is still under development.
