<Transparent substrate with display device>
FIG. 1 is a top view illustrating a transparent substrate 100 with a display device in the embodiment. 2A and 2B are diagrams illustrating the transparent substrate 100 with a display device in the embodiment, in which FIG. 2A is a front view, FIG. 2B is a bottom view, and FIG. 2C is a side view.

  As shown in FIGS. 1 and 2, the display-equipped transparent substrate 100 includes a transparent substrate 10 having a transparent region 11 and a colored region 20, a display device 30, a bonding member 40, a support member 50, and a fixed frame 60. In the following description, the surface of the transparent substrate 10 on the display device 30 side is referred to as the back surface, and the surface of the transparent substrate 10 opposite to the display device 30 is referred to as the front surface.

(Transparent substrate)
The transparent substrate 10 is, for example, soda lime glass, aluminosilicate glass, aluminoborosilicate glass, inorganic glass such as non-alkali glass, or organic glass made of polycarbonate resin, acrylic resin, or the like. Further, the transparent substrate 10 may be a laminated glass in which a plurality of glass plates are bonded, or a laminate of inorganic glass and organic glass.

  When the transparent substrate 10 is inorganic glass, for example, a surface strengthening process such as a chemical strengthening process or a physical strengthening process may be performed.

  Further, an antireflection film may be provided on the front surface of the transparent substrate 10. The antireflection film is, for example, a silicate or metal oxide thin film, and is directly formed on the surface of the transparent substrate 10 by sputtering, vapor deposition, wet coating, or the like. Alternatively, the antireflection film is formed by laminating a resin thin film having a low refractive index such as a fluororesin to the surface of the transparent substrate 10 via an adhesive layer or the like. In particular, an antireflection film having a fluororesin in the outermost layer is preferable because it can impart antifouling performance and easy cleanliness to the transparent substrate 10. Reflection is suppressed by such an antireflection film, and an image displayed on the display device 30 from the outside can be seen more clearly.

  The transparent substrate 10 has a transparent region 11 and a colored region 20. The colored region 20 may be colored and transparent or colored and opaque, and may have a gradation with color shading depending on the location. The shape of the colored region 20 is not particularly limited, and may be a frame shape or the like. The transparent region 11 of the transparent substrate 10 is preferably provided to face the display unit of the display device 30. The design property of the transparent substrate 10 can be improved by changing the formation region of the colored region 20 to make the transparent region 11 into various shapes.

  The colored layer of the colored region 20 is formed in a predetermined region on the front surface or the back surface of the transparent substrate 10 by, for example, screen printing using a paint containing a ceramic pigment. A colored layer may be formed by different methods, such as inkjet printing, for example, and may be formed by pasting a film etc.

  In addition, although the transparent substrate 10 in this embodiment is a rectangle, arbitrary shapes other than a rectangle may be sufficient.

  The display device 30 and the transparent substrate 10 are bonded to the back surface of the transparent substrate 10 with an adhesive such as an adhesive or a double-sided adhesive tape, for example. Examples of the adhesive and the pressure-sensitive adhesive used for bonding the transparent substrate 10 and the display device 30 include a transparent resin and a liquid curable resin composition. For example, when the adhesive is a curable resin composition, an uncured resin composition is applied to the back surface of the transparent substrate 10 and the display device 30 is disposed, and then the resin composition is cured, thereby the display device. 30 can be bonded to the transparent substrate 10.

The adhesive and pressure-sensitive adhesive preferably have a shear modulus at 25 ° C. of, for example, 10 ³ Pa to 10 ⁷ Pa, and more preferably 10 ⁴ Pa to 10 ⁶ Pa. In particular, when the shear modulus at 25 ° C. of the adhesive and the pressure-sensitive adhesive is 10 ⁴ Pa to 10 ⁵ Pa, voids that can be generated when the display device 30 and the transparent substrate 10 are joined are relatively easily lost. Can be made.

When the shear modulus at 25 ° C. of the adhesive and the pressure-sensitive adhesive is 10 ³ Pa or more, the shape of the applied adhesive and pressure-sensitive adhesive is easily maintained. Therefore, even when the thickness of the applied adhesive and pressure-sensitive adhesive is relatively large, the thickness of the adhesive and the pressure-sensitive adhesive is maintained uniformly, and when the display device 30 and the transparent substrate 10 are joined, It becomes difficult to generate a gap at the interface between the display device 30 and the adhesive.

In addition, the adhesive and the pressure-sensitive adhesive have a shear modulus at 25 ° C. of 10 ⁴ Pa or more, and are prevented from being deformed. The shear modulus at 25 ° C. is 10 ⁷ Pa or less, and the adhesive bonding between the display device 30 and the transparent substrate 10 is performed. Improves.

  For example, the thickness of the adhesive and the pressure-sensitive adhesive is preferably 0.03 mm to 2 mm, and more preferably 0.1 mm to 0.8 mm. If the thickness of the adhesive and the pressure-sensitive adhesive 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 and the pressure-sensitive adhesive sufficiently reduce the impact due to the external force. Can protect. In addition, even if a foreign substance having a size smaller than the thickness of the adhesive and the adhesive is mixed between the display device 30 and the transparent substrate 10, the thickness of the adhesive and the adhesive does not change. The influence on sex is suppressed. Moreover, since the visibility of the display apparatus 30 falls, it is preferable that the thickness of an adhesive agent and an adhesive is 2 mm or less.
