Abstract

A display apparatus according to the present invention includes a transmission type of fluorescent display lamp (FL) 1 on which a pattern layer is not masked. The rear and front spaces of the transmission type FL 1 are defined by frames 5, 6. On each frame 5, 6 is attached an illumination display member, such as a light guide plate 8 or a transmission sheet 9, so that illumination displays are provided at both front and rear sides of the FL 1 by a light emitting source 10 such 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 1, a wider representation and functional display through a microcomputer control can be performed. Use of the light emitting source 10 lowers cost in comparison with the conventional biplanar type of FL.
