ABSTRACT:
A displaying apparatus (10) is configured such that illumination light emitted from light sources (15, 15 . . .) disposed on a back side of a liquid crystal displaying plate (11) illuminates an optically transparent displaying section (16a) of a dial plate (16) provided on a front side of the liquid crystal displaying plate (11) by passing through the liquid crystal displaying plate (11). Further, polarizing plates (13, 14) overlapping the optically transparent displaying section (16a) are cut out from the liquid crystal displaying plate, whereby the illumination light may illuminate the optically transparent displaying section (16a), passing through a liquid crystal displaying plate (111).
