PROBLEM TO BE SOLVED : the character or the like even in the dark place clear crystal plate, can be displayed for long time, and, the current consumption is suppressed, the thickness can be reduced, preferably to the environment, is not equipped with the liquid crystal panel backlight photolimunescence high luminance. SOLUTION : the back light and the liquid crystal panel is not photolimunescence high luminance, by the numeral has a segment display notoginseng or display characters and liquid crystal plate 3, is arranged so as to sandwich the liquid crystal panel polarizing plate and the first polarizing plate 2 by the reflection type polarization plate and a second plate 4, natural light, absorption and emission can be repeated, including no radiation, aluminate compounds of rare earth elements are attached is mainly generated by firing photolimunescence pigment is applied to the surface of the sheet and a photolimunescence sheet 5, is provided, from the direction of incidence of natural light, a first polarizing plates, liquid crystal panel, a second polarizing plate, on the order of photolimunescence and characterized. Selected drawing : fig. 1 |
