INFORMATION DISPLAY DEVICE

1 . An information display device attachable to a structure, comprising:

a display panel that has a display surface and displays information on the display surface; and

a surface member that is disposed on a display surface side of the display panel and has a surface area larger than that of the display panel,

wherein, when the display panel is turned on, only the information displayed on the display surface of the display panel becomes visible through the surface member.

2 . The information display device of claim 1 ,

wherein, when the display is turned off or when information is not displayed on the display surface of the display, the display panel becomes invisible through the surface member.

3 . The information display device of claim 1 ,

wherein a light transmittance of the surface member is 8% to 15%.

4 . The information display device of claim 1 ,

wherein the display panel has a screen luminance of 200 cd/m{circumflex over ( )}2 or less after transmission through the surface member.

5 . The information display device of claim 1 ,

wherein the display panel has a luminance of the display surface adjusted to 800 cd/m{circumflex over ( )}2 or more.

6 . The information display device of claim 1 , further comprising:

a structural body attached to a back side of the surface member,

wherein the structural body has a retainer for fixing the information display device to the structure at a position not visible from a front side of the surface member.

7 . The information display device of claim 6 ,

wherein the structural body is disposed at a position that does not overlap a display surface of the display panel.

8 . The information display device of claim 6 ,

wherein at least the surface member side of the structural body is colored with substantially the same color as that of the display surface when the display panel is turned off.

9 . The information display device of claim 1 ,

wherein, between the display panel and the surface member, a region other than the display surface that surrounds the display surface has a colored layer colored with substantially the same color as that of the display surface when the display panel is turned off.

10 . The information display device of claim 9 ,

wherein the colored layer has a higher light transmittance as being closer to the display surface.

11 . The information display device of claim 9 ,

wherein an edge of the colored layer that surrounds the display surface has a rounded shape with an arc-shaped corner.

12 . The information display device of claim 1 , further comprising:

a touch panel disposed between the display panel and the surface member; and

a cushion member disposed to be peelable between the surface member and the touch panel, and formed of a material that has light transmitting properties, and deforms when a force is applied thereto.

13 . The information display device of claim 12 , further comprising:

a non-adhesive layer that is disposed on at least one of the front side and the back side of the cushion member and prevents the cushion member from adhering to the surface member or the touch panel.

14 . The information display device of claim 1 ,

wherein the structure is a wall, a ceiling, a door of a container, or a seat disposed in a moving object, and the information display device is disposed at a position visible from a passenger or a crew of the moving object.
