A main illumination light source 6 that emits light toward the front of the rear panel 5 is arranged on the side. Reference numeral 7 indicates a light shielding plate.

The front panel 4 is formed by applying an opaque colored layer 9 on the front surface (opening window side) of a plate-shaped transparent substrate 8 in a state having fine blank portions 9a in the form of fine mesh, dots, or lines. A desired colored pattern or colored character is formed from the opaque colored layer 9. On the other hand, the rear panel 5 is a plate-shaped transparent base material 8 on which an opaque colored layer 9 is applied to the front surface (front panel side). The opaque colored layer 9 forms a desired colored pattern or colored characters, and the front panel 4 Blank part 9a
Through the through, the opaque colored layer 9 on the front surface of the rear panel 5 is provided so that pictures, characters and the like can be visually recognized.

Specifically, as shown in FIG. 2, the opaque colored layer 9 provided on the front surface of the front panel 4 has a two-layer structure.
The transparent substrate 8 side is used as a shielding layer 9b, and a pattern layer 9c is superposed on the shield layer 9b (a monochrome or multicolor solid image, line drawing, or gradation reproduction is constituted by the pattern layer 9c). Also, the opaque colored layer on the front surface of the rear panel 5 has a two-layer structure, and the transparent base material side is used as a shielding layer, and the pattern layer is laminated thereon.

In the rear panel 5, as shown in FIG. 3, an opaque colored layer 9 may be provided on the back side, or the opaque colored layer 9 may be provided on the back side and the opaque colored layer 9 may be provided on the front side as described above. It may be applied in a state having a fine blank portion 9a in the form of fine mesh, dot, line, or the like. The opaque colored layer 9 on the front side has a two-layer structure to form other colored patterns and colored characters, and the opaque colored layer 9 on the back side has a two-layer structure to form colored patterns and colored characters. As shown in FIG. 4, the opaque colored layer on the side can be configured so that the shielding layer 9b is superposed on the reflective layer 9d on the transparent substrate 8 side.

The area of the blank portion 9a itself of the opaque colored layer 9 on the front side of the front panel 4 does not prevent the display of the colored pattern or the colored characters on the rear panel 5 side. The shielding layer 9c may be provided as a reflective layer by applying white ink, silver ink, and aluminum vapor deposition.

In the display device 1 shown in FIG. 1, when the main illumination light source 6 is turned off, a picture, characters, etc. by the opaque colored layer 9 of the front panel 4 are displayed. When the main illumination light source 6 is turned on, the front surface of the rear panel 5 is illuminated, the pattern and characters of the rear panel 5 are displayed through the blank portion 9a of the front panel 4, and the opaque colored layer 9 of the front panel 4 that blocks light.
