The rear and front spaces of the transmission type FLare defined by frames. On each frameis attached an illumination display member, such as a light guide plateor a transmission sheet, so that illumination displays are provided at both front and rear sides of the FLby a light emitting sourcesuch as an LED, fluorescent lamp and so on. Thus, a greater three-dimensional visual effect (depth perception) can be obtained. Further, by utilizing spaces in the front and the rear of the transmission type FL, a wider representation and functional display through a microcomputer control can be performed. Use of the light emitting sourcelowers cost in comparison with the conventional biplanar type of FL.
