  When the mirror 100 with a display device is installed in a clothing store or the like, it is displayed on the display device 30 provided on the back of the transmission part 1a and the appearance of the customer trying on the product with the above-described configuration. It becomes possible to confirm the image at the same time. In addition, when installed in a store or the like, not only in a clothing store, the above-described configuration prevents the mirror image reflected on the mirror surface portion 2 and the screen displayed on the display device 30 from interfering with each other. Will improve.

<Display device>
A display device 30 is provided on the back surface of the transparent portion 1 a of the transparent substrate 10. The display device 30 is, for example, a liquid crystal display device, an organic EL display device, a plasma display device, or the like. The display device 30 displays, for example, an image stored in a storage device (not shown) or an image transmitted from a computer or server connected via a network on the display unit 30a. As described above, when the mirror 100 with a display device is installed in a clothing store or the like, the display device 30 displays an advertisement image of a product, product information required by a customer, or the like.

  As shown in FIG. 2, the display device 30 is brought into close contact with the back surface of the transmissive portion 1 a of the transparent substrate 10 by the adhesive 11 filled between the display portion 30 a and the back surface of the transmissive portion 1 a of the transparent substrate 10. It is joined to.

  As described above, the adhesive 11 is filled between the display unit 30 a of the display device 30 and the transmission unit 1 a of the transparent substrate 10, so that a reflection image of the display unit 30 a is formed on the back surface of the transmission unit 1 a of the transparent substrate 10. It becomes difficult to form. Therefore, the image displayed on the display unit 30a of the display device 30 can be seen more clearly from the front side of the transparent substrate 10, and the visibility of the display device 30 is improved.

  In addition, the area of the display unit 30 a of the display device 30 is larger than the area of the transmission unit 1 a, and the outer peripheral edge of the display unit 30 a is provided on the back surface of the mirror surface unit 2 so as to overlap the mirror film 20. With such a configuration, the outer peripheral edge of the display unit 30a of the display device 30 becomes invisible from the front side of the transparent substrate 10, and the design of the mirror 100 with a display device is improved. Furthermore, since the outer peripheral edge of the display unit 30 a is not visible from the front surface of the transparent substrate 10, an effect is obtained in which an image displayed on the display unit 30 a appears to float up on the front side of the transparent substrate 10.

A plurality of display devices 30 may be provided. The plurality of display devices 30 are bonded to the back surface of the transmission unit provided at different positions, for example, with the above-described configuration.
(adhesive)
The adhesive 11 used for joining the display device 30 and the transmission part 1a of the transparent substrate 10 is, for example, a transparent resin or a liquid curable resin composition. For example, when the adhesive 11 is a curable resin composition, an uncured resin composition is applied to the back surface of the transmission portion 1a and the display device 30 is disposed, and then the resin composition is cured to display The device 30 can be bonded to the transmission part 1 a of the transparent substrate 10.

The adhesive 11 has a shear modulus at 25 ° C. of, for example, preferably 10 ³ Pa to 10 ⁷ Pa, and more preferably 10 ⁴ Pa to 10 ⁶ Pa. In particular, when the shear modulus of elasticity of the adhesive 11 at 25 ° C. is 10 ⁴ Pa to 10 ⁵ Pa, the gap that may be generated when the display device 30 and the transparent substrate 10 are joined is relatively easily lost. Can do.

When the shear modulus at 25 ° C. of the adhesive 11 is 10 ³ Pa or more, the shape of the applied adhesive 11 is easily maintained. Therefore, even when the applied adhesive 11 is relatively thick, the thickness is kept uniform throughout the adhesive 11, and when the display device 30 and the transparent substrate 10 are joined, the display device 30 It becomes difficult to generate voids at the interface with the adhesive 11.

The adhesive 11 has a shear modulus at 25 ° C. of 10 ⁴ Pa or more and is prevented from being deformed. The shear modulus at 25 ° C. is 10 ⁷ Pa or less. Bonding adhesion is improved.

  For example, the thickness of the adhesive 11 is preferably 0.03 mm to 2 mm, and more preferably 0.1 mm to 1 mm. If the thickness of the adhesive 11 is 0.03 mm or more, when an external force or the like is applied from the front surface of the transparent substrate 10, the adhesive 11 can sufficiently reduce the impact due to the external force and protect the display device 30. In addition, even if a foreign object having a size smaller than the thickness of the adhesive 11 is mixed between the display device 30 and the transparent substrate 10, the thickness of the adhesive 11 does not change, and thus the visibility due to the foreign material is not affected. Is suppressed. Moreover, since the visibility of the display part 30a of the display apparatus 30 falls, it is preferable that the thickness of the adhesive agent 11 is 2 mm or less.

<Communication device>
A communication device 40 is provided on the back surface of the transparent portion 1 b of the transparent substrate 10. The communication device 40 transmits the data acquired via the transmission unit 1b to the display device 30. Based on the data transmitted from the communication device 40, the display device 30 displays, for example, image data acquired from a storage device (not shown) on the display unit 30a.

  When the mirror 100 with a display device is installed in a clothing store or the like, for example, when a customer holds a product tag or the like over the transmission unit 1b, the data acquired by the communication device 40 reading the tag is displayed on the display device 30. The display device 30 displays product information and the like. Or a customer transmits data to the communication apparatus 40 using portable terminals, such as a smart phone and a tablet PC, and the display apparatus 30 displays the information which a customer requires based on the data transmitted to the communication apparatus 40. FIG.

<Example of installation of mirror with display device>
As described above, the mirror 100 with a display device is installed in, for example, a partition or a pillar of a clothing store, and the customer's own try-on product reflected in the mirror surface 2 and product information displayed on the display device 30. Can be viewed at the same time. Further, the communication device 40 reads a tag or the like attached to the product and causes the display device 30 to display information related to the product, thereby providing the customer with necessary information.

  The mirror 100 with a display device may be installed in a fitting room of a clothing store. In this case, for example, a camera that captures a customer facing the mirror 100 with a display device from behind is installed, and an image captured by the camera is displayed on the display device 30. With such a configuration, a customer who has tried on a product can simultaneously check the appearance from the front of the customer shown in the mirror surface portion 2 and the appearance from the back of the customer displayed on the display device 30. The customer can check the product from the front and back and judge whether the product is good or bad without looking back.

  Furthermore, the mirror 100 with a display device may be installed in a beauty salon. In this case, for example, a camera that photographs a customer sitting on the seat facing the mirror 100 with a display device from behind is installed, and an image captured by the camera is displayed on the display device 30. With such a configuration, the customer can simultaneously confirm the appearance from the front reflected on the mirror surface portion 2 and the appearance from the back displayed on the display device 30. The customer can check his / her hairstyle without using a hand mirror or the like.
