(multilayer glass)

As shown in FIG. 3, the multilayer glass is composed of two glass plates 11 and 12 which are stacked with the spacer 17 provided on the peripheral edge. And as shown in Figure 3, in the sandwich A hollow layer 25 is formed between the glass plate 11 and the glass plate 12 which are overlapped by the spacers 17. The hollow layer 25 is surrounded by a spacer 17 to be sealed and isolated from the external environment. The hollow layer 25 is filled with, for example, air or an inert gas or the like. The thickness of the glass plate is usually about 2 to 6 mm. The thickness of the glass plate can be exemplified by 1 to 6 mm. The thickness of the hollow layer can be exemplified by 6 to 25 mm.

As the glass plates 11 and 12, for example, soda lime glass, aluminosilicate glass, aluminoborosilicate glass, alkali-free glass, and organic glass can be used, but it is not limited thereto. Further, the glass plate 11 and/or the glass plate 12 may be subjected to a chemical strengthening treatment or a physical strengthening treatment.

By performing the surface strengthening treatment on the glass sheet, the strength of the glass sheet is increased, and the thickness of the glass sheet 11 can be made thinner.

(frame)

The frame 15 is formed using, for example, a metal material, a resin material, or the like, and as shown in FIGS. 2 and 3, a peripheral portion of a plurality of glass sheets is sandwiched and fixed. The frame 15 can also have, for example, a track for switching in the X direction of the display case 100, a hinge member for opening and closing in the Y direction, and a handle for opening and closing the glass door 10.

(transparent display)

The transparent display 70 is, for example, a transmissive display device such as a liquid crystal display device or an organic EL display device. The transparent display 70 is not limited to the above example as long as it is a transmissive display device. The liquid crystal display device may be a dispersion-type liquid crystal display device (manufactured by Asahi Glass Co., Ltd.: Transmart), or may have a light guide plate on the back surface of the liquid crystal substrate. Creator. Further, a plurality of transparent displays 70 of the same type or different types may be provided in the glass door 10. For example, using a plurality of transparent displays 70, a transparent display 70 is provided for each item in the display case 100 to display different information about each item. The visible light transmittance of the transparent display 70 in the non-display state is preferably 15 to 30%.

As shown in FIG. 3, the transparent display 70 is provided on a surface of at least one of the plurality of glass sheets facing the hollow layer 25. The transparent display 70 is then attached to and fixed to the surface of any one of the glass plate 11 and the glass plate 12, but is preferably disposed on the side of the hollow layer 25 side of the glass plate 11 outside the cabinet of the display cabinet 100, and the display surface is oriented. external. With the configuration, the number of interfaces from the consumer side to the transparent display 70 can be reduced, and the image represented by the transparent display 70 can be seen more vividly through the glass plate 11.

The transparent display 70 displays images such as still images and animations for advertising advertisements such as the products 50 displayed inside. The image displayed on the transparent display 70 is, for example, an image stored in a storage device (not shown), or an image transmitted from a server connected via a network or the like.

The transparent display 70 is a transmissive display device, so that even when an image is being displayed on the transparent display 70, the consumer can see the article 50 displayed on the back shelf 30 across the image displayed on the transparent display 70. That is, when an image is displayed on the transparent display 70, the consumer will superimpose the image displayed on the transparent display 70 and the article 50 behind it.

In addition, the transparent display 70 may be disposed on a portion or substantially the entire surface of the glass door 10, but it is preferably disposed on the substantially entire surface in such a manner that the outer circumference is located between the inner circumference and the outer circumference of the frame 15 as shown in FIG. By the structure described, The outer periphery of the transparent display 70 is not exposed to the outside, and the appearance of the glass door 10 can be maintained. Further, as shown in FIG. 4, it is more preferable that the outer periphery of the transparent display 70 is interposed between the spacer 17 and the glass plate 11. With the configuration described above, the adhesion of the transparent display 70 to the glass plate 11 can be further improved. In addition to the example shown in FIG. 4, the outer periphery of the transparent display 70 can also reach the outer periphery of the glass plate 11.

(Glass plate and transparent display)

The transparent display 70 can be adhered to the glass plate 11 by using, for example, a transparent adhesive or a transparent adhesive (collectively referred to as "clear adhesive"), or using a transparent adhesive or tape. The transparent adhesive and the adhesive tape may be applied or adhered to the entire surface of the transparent display 70, and may be coated or adhered to one portion of the peripheral portion or the like. When the transparent adhesive and the tape are applied or adhered to the entire surface of the transparent display 70, since the glass plate 11 and the transparent display 70 become air-free, the display image becomes sharp. As the transparent adhesive, for example, a transparent resin or a liquid curable resin composition can be used. In addition, illustration of such transparent adhesives is omitted.

When a curable resin composition is used, the uncured resin composition is applied to the surface of the glass sheet 11 on the side of the hollow layer 25, and after the transparent display 70 is placed thereon, the resin composition is cured to bond the glass. Plate 11 and transparent display 70.

The shear modulus of the transparent adhesive at 25 ° C is preferably in the range of 10 ³ Pa to 10 ⁷ Pa, and preferably in the range of 10 ⁴ Pa to 10 ⁶ Pa. In particular, in the case where the transparent modulus of the transparent adhesive is in the range of 10 ⁴ Pa to 10 ⁵ Pa at 25 ° C, the void which may be generated when the glass plate 11 and the display device 170 are joined can be easily eliminated.

When the shear modulus at 25 ° C is 10 ³ Pa or more, the shape of the transparent adhesive can be appropriately maintained. Further, even when the thickness of the transparent adhesive is thick, the thickness of the entire transparent adhesive can be uniformly maintained, so that it is difficult to interface the transparent display 70 and the transparent adhesive when bonding the glass plate 11 and the display device 170. A gap has occurred.

Further, when the shear modulus at 25 ° C of the transparent adhesive is 10 ⁴ Pa or more, the deformation of the transparent adhesive can be intentionally suppressed. When the shear modulus of the transparent adhesive is 10 ⁷ Pa or less, good adhesion is exhibited in the bonding of the glass plate 11 and the transparent display 70.

The thickness of the transparent adhesive is preferably from 0.03 mm to 2 mm, more preferably from 0.1 mm to 0.8 mm.

When the thickness of the transparent adhesive is 0.03 mm or more, when an external force or the like is applied from the outside of the glass sheet 11, the transparent adhesive reduces the impact by the external force, and the transparent display 70 can be protected. Further, even if foreign matter having a size smaller than the thickness of the transparent adhesive is mixed between the glass plate 11 and the transparent display 70, the thickness of the transparent adhesive does not change, so that the light transmission property due to the incorporation of foreign matter can be suppressed. influences. Moreover, by making the thickness of the transparent adhesive 2 mm or less, it is possible to suppress the partial thickness of the transparent display 70 from being excessively thick due to the transparent adhesive.

Further, the transparent adhesive may be a non-single layer, and may be composed of a layered portion in a central portion in plan view and a beak portion surrounding the layered portion. For example, when the transparent adhesive is formed from the liquid curable resin composition, the beak portion is used to inhibit the curable resin composition from spreading beyond the predetermined range (ie, blocking the layered shape). Liquid hardening tree The fat composition is streamed out). The crotch portion may be formed by curing a curable resin composition different from the curable resin composition constituting the layer portion of the central portion.

(functional membrane)

The glass plate 11 or the glass plate 12 may be provided with a low-radiation film 24 as a functional film on at least a part thereof. In order to improve the heat insulating effect, the low-radiation film 24 is preferably provided on the side of the hollow layer 25 side of the glass sheet 12 inside the cabinet 100 cabinet.

The low-radiation film 24 is preferably composed of a laminated film of a film, and is preferably composed of a laminated film in which a film mainly composed of silver is an oxide film containing zinc as a main component. Sandwiched (zinc oxide / silver / zinc oxide). In order to reduce the emissivity, the above laminated film is preferably made into two layers (zinc oxide/silver/zinc oxide/silver/zinc oxide). According to the laminated film described above, since the transmittance is high and the radiation is low, the visibility of the inside of the display cabinet 100 can be maintained while maintaining the heat insulating property.

Further, an anti-reflection film may be provided on the outer surface of the glass plate 11 on the outer side of the cabinet of the display cabinet 100. The anti-reflection film is formed by directly depositing a film of a niobate and a metal oxide on the outer surface of the glass sheet 11 by sputtering or vapor deposition at a predetermined film thickness. Alternatively, the anti-reflection film can be formed by bonding a low refractive index resin film such as a fluororesin to the outer surface of the glass panel 11 via an adhesive layer or the like. In particular, those having a fluorine resin in the outermost layer are preferable because they can impart antifouling properties and easy cleanability.

Since the antireflection film is provided on the outer surface of the cabinet of the glass plate 11, the reflection is suppressed, and the image displayed on the transparent display 70 can be more clearly seen from the outside.
