By providing a black impermeable layer leaving the display of characters, scales, symbols, etc., only the display can be transmitted, a light source is provided behind the translucent substrate, and the light source is turned on to Some illuminate the display through transmission.

According to this display plate, when the light source is in a non-illuminated state, the white transmissive color layer is visually recognized at a display portion where the non-transmissive layer is not present, and the white background is formed of the non-transmissive layer. On the other hand, the white display is visually recognized.

Further, when the light source is in a lighting state, a portion corresponding to the non-transmissive layer is visually recognized as a black background, and only the display portion without the non-transmissive layer is provided on the back surface from the light source. The light is transmitted and illuminated through the white transmission color layer.

However, in the display plate, there is no difference in the display form between when the light source is turned on and when the light source is not turned on, and the white display is visually recognized against the black background. However, there was a problem that it lacked in productability and design.

The applicant of the present application has proposed a display plate disclosed in Japanese Patent Laid-Open No. 2000-221062 to solve such a problem.

In such a display plate, a transmissive portion having no light-shielding layer is provided on a part of a translucent substrate, and an offset printing portion formed by combining a plurality of colored layers is provided on the transmissive portion. The offset printing section is provided so that it can be transmitted and illuminated by turning on a light source provided behind the flexible substrate, and a smoke layer is provided to cover the front surface side of the offset printing section. On the display plate, due to the effect of the smoke layer, the display is not visible when the light source is not lit, but the display is transmitted and illuminated when the light source is lit. The display form can be greatly different depending on the time.
