[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a display panel used for displaying various sheet-shaped display bodies.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, as a panel material that can easily display displays such as posters and photographs, an adhesive layer has been formed on a base material made of a synthetic resin foam plate, and a transparent film is attached on it. What is done is known. In such a panel material, a part of the transparent film is peeled from the base material, the display body is attached to the surface of the base material on which the adhesive layer is formed, and then the transparent film is reattached to the original state. Is used as a display.

However, when a display body is displayed using such a panel material, it is difficult to cleanly remove the display body from the substrate after the display body is firmly attached to the adhesive layer and the display is finished. In many cases, such a drawback becomes conspicuous when the display body is displayed for a long period of time. Not only that, even if the display can be peeled off neatly, the adhesive strength of the adhesive will be lost as the display and the transparent film are repeatedly attached and removed. It was unsuitable to replace one display with another and use one panel repeatedly.

On the other hand, a panel material in which a synthetic resin foam plate and a transparent sheet are fixed to each other at one side is also known (Actual Kaihei No. 6-4774), and such a panel material is a foam plate and / or plastic. The static electricity generated by the contact friction between the sheet and the paper display body is used to hold the display body between the foam plate and the transparent sheet.

However, when the panel material as described above is used for a display, if the atmosphere in which the panel material is used has a large amount of moisture, it becomes difficult for the panel material and the display body to be electrostatically charged. However, in such a case, the display body is not sufficiently held between the foam plate and the transparent sheet, and the display body easily slides off from the panel material. It had the drawback of being influenced by the environment in which it was used.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art. One panel material can be repeatedly used while exhibiting sufficient holding power, and the panel material can be used repeatedly. An object of the present invention is to provide a display panel capable of securely holding a display body regardless of the environment in which the material is placed.

[0007]

[Means for Solving the Problems]

 In the display panel of the present invention, a rectangular front sheet and a back sheet are the sides to which one end of the peripheral joint portion belongs by the peripheral joint portions which are continuous over three sides of these sheets. Display joined at a portion occupying 3 to 45%, a side to which the other end of the peripheral edge joint belongs and occupying 55 to 97% of the side, and a part of the periphery excluding the sides other than the three sides. The body holding member is attached to the plate-shaped substrate from the back sheet side of the display body holding member.

In the present invention, the non-bonded portion of the side to which one end of the peripheral edge joined portion occupies 5 to 30% of the side, and the non-bonded portion of the side to which the other end of the peripheral edge joined portion belongs to the side. It is preferable to occupy 70 to 95% of the above, and the plate-shaped substrate to which the display material holding member is attached is preferably a polystyrene resin foam plate.
