Abstract

An information display sheet includes: a transparent first substrate; a second substrate spaced away from and parallel to the transparent first substrate; a sound reproducer provided in a space formed by side edges stipulated by the transparent first substrate and the second substrate; and an information display unit provided in the space, having an information displaying section arranged facing the transparent first substrate for displaying image information.

Claims

1. An information display sheet comprising:

(a) a transparent first substrate;

(b) a second substrate spaced away from and parallel to the transparent first substrate;

(c) a sound reproducer provided in a space formed by side edges stipulated by the transparent first substrate and the second substrate; and

(d) an information display unit provided in the space, having an information displaying section arranged facing the transparent first substrate for displaying image information, wherein a spatial region that has a surface parallel to the side edges and a specific width, is provided within the space, the region of the first substrate and second substrate positioned within the spatial region is made as a folding and bending section, thereby the information display sheet is capable of being folded along the spatial region.

2. The information display sheet of claim 1, wherein holes penetrating the first substrate are provided in a region of the first substrate positioned in the spatial region.

3. The information display sheet of claim 2, wherein the sound reproducer, a spatial section formed between the transparent first substrate and the second substrate, and the spatial region are linked together.

4. The information display sheet of claim 1, wherein the information display unit has memory characteristics by which a display state is maintained when a power supply has been stopped.

5. The information display sheet of claim 4, wherein the information display unit has a displaying section employing cholesteric liquid crystals, a display section employing electrophoretic particle, or a display section employing chemical compounds having electrochromic characteristics.

6. The information display sheet of claim 1, wherein a thickness of the first and second substrates is 100 to 500 μ

m.

7. The information display sheet of claim 1, wherein a height of a space formed by side edges stipulated by the first and second substrates, and the first and second substrates is about 1 to 1.5 mm.
