FIG. 6 is a view showing a second embodiment of the present invention, in which a half mirror layer 31 is formed by vapor-depositing a half mirror on the back surface of the transparent member 30, and the surface of the transparent member 30 is A coating screen is directly applied by vacuum vapor deposition or the like, and the coating screen 32 is laser-cut to form a display unit 33. The LCF 34 is disposed on the back surface of the translucent member 30.
To diffuse the light of the lamp (not shown) on the back of the
For example, a light diffusing treatment 35 such as painting, printing, or sandblasting of a semi-transparent paint or diffusing material, or embossing on the back surface of the LCF 34 is performed. Also in this embodiment, as in the first embodiment, the light of the lamp is diffused by the light diffusing process applied to the back surface of the LCF 34, and then the LC
It is polarized by F34 so as to travel only in a predetermined direction, passes through the half mirror layer 31 and is slightly refracted by the translucent member 30, and travels through the display unit 33 in the upper right direction, that is, in the direction in which the driver is located.

As is apparent from the above description, according to the present invention, after the light from the light source is diffused by the light diffusing process on the back surface of the LCF, it travels in the predetermined direction by the directional member. From the direction, the display section is uniformly illuminated and the filament of the light source cannot be seen. Then, the light of the light source becomes a substantially parallel light beam by the directional member and travels in a fixed direction, so that it does not disperse, it is not necessary to increase the light amount of the light source more than necessary, and the light may be reflected to the window. It has the effect of avoiding glare. Further, since the half mirror layer having high reflectance is provided, the inside cannot be seen in the daytime, and external light is reflected from the half mirror layer and can be seen from the display portion, so that the display can be clearly seen. Have an effect.
