Problems solved by technology
[0029] As mentioned above, in the prior art, various anti-counterfeiting technologies are disclosed, but when these technologies are used, it is not a countermeasure to prevent theft or tampering with stolen goods, it is better to say that the level of anti-counterfeiting is high, so When using a stolen or falsified product, there is a problem that it is difficult to distinguish it from the genuine product

Embodiment
[0078] Next, the structure of the reflective resin sheet (4) which can be used for the display device of this invention, and a display device are demonstrated, referring drawings.
[0079] Fig. 1 (A)~(C) is the figure illustrating display device (25) of the present invention, and Fig. 1 (A) shows that display device (25) is made of surface protection layer (21), information display layer (24), reflective It consists of a resin sheet (22) and a base adhesive layer (23). Fig. 1(B) shows a plan view of a display device (25), and in this figure, specifically, a vehicle license plate is shown. The display device (25) is pasted on the installation substrate (28) with a substrate adhesive layer (23). The mounting base material (28) in FIG. 1 is specifically a resin bumper of a vehicle, and is preferably mounted with screws in order to make the mounting strength stronger. FIG. 1(C) shows a state in which a display device (25) is mounted on a mounting substrate (28).

Abstract
A display device on which a mirror surface reflection layer (16) is provided and which is excellent in preventing theft and manipulation. The display device has a surface protection layer (1), an information display layer (3), a reflective resin sheet (4), and a base material adhesion layer (5). A mirror surface reflection layer (16) is provided on the reflective resin sheet (4) with a destruction layer (14) and a focus forming layer (15) in between. When the display device is separated from an installation base material (6), the mirror surface reflection layer (16) is separated by separation at the boundary surface between the destruction layer (14) and the reflective resin layer (4) or mirror surface reflection layer (16) in contact with the destruction layer and / or by destruction of the destruction layer (14), and the separated mirror surface reflection layer (16) remains on an installation base material (6). An RFID device can be placed on the back surface of the display device.
Description
technical field [0001] The present invention relates to a display device with an anti-theft structure, which is at least composed of a surface protection layer (1), an information display layer (3), a light-reflective resin sheet (4) and a substrate adhesive layer (5) The display device is characterized in that a specular reflection layer (16) is provided on the light-reflective resin sheet (4) with the destructive layer (14) interposed therebetween, and the substrate adhesive layer (5) is interposed In the middle, the specular reflection layer (16) of the display device is bonded to the installation substrate (6). The peeling at the interface of any layer of the contacted reflective resin sheet (4) and / or the peeling occurs due to the damage of the damaged layer (14), and the specular reflection layer (16) remains on the mounting substrate (6) superior. [0002] Specifically, it is a display device such as various signs, labels, billboards, etc. Since the specular reflectio...
