Featuring the thinness and the excellent face illumination, Electroluminescence (EL) has a wide variety of applications. We have already commercialized wall clocks that allow you to read the time at night and alarm clocks that are more than 1000 times brighter than luminous paint. EL has thus not only contributed to enhancing the convenience of clocks by increasing their visibility at night, but also it is useful from the viewpoint of environmental protection because it can be used as a substitute for luminous paint containing radioactive substances. Further, EL has been used as the liquid crystal backlight in compact displays for watches. To find much more applications, EL sealed with film must be reduced in size. With this background, to reduce the restraints on the outside dimensions of EL and to cut costs, we have put nonsealed ultra-thin type EL to practical use. This paper reports on basic construction and characteristics of nonsealed ultra-thin type EL and how it has come to have wide application.
