As shown in FIGS. 1 and 2, the transparent substrate 10 includes a light-transmitting portion 1 that transmits light and a light-shielding portion 2 on which a colored layer 20 is formed. The light shielding part 2 is preferably formed on the back surface of the transparent substrate 10.
　透過部１は、透明基板１０の背面に着色層２０が形成されておらず、周囲が遮光部２に囲まれて光を透過する部分である。透過部１の背面には、表示装置３０が設けられ、透明基板１０の前面側から透過部１を介して表示装置３０に表示される画像を見ることが可能になっている。なお、本実施形態において、透過部１の形状は矩形であるが、矩形以外の任意の形状であってもよい。 The transmitting portion 1 is a portion where the colored layer 20 is not formed on the back surface of the transparent substrate 10 and the periphery is surrounded by the light shielding portion 2 and transmits light. A display device 30 is provided on the back surface of the transmissive portion 1 so that an image displayed on the display device 30 can be viewed from the front surface side of the transparent substrate 10 via the transmissive portion 1.

　また、例えば透明基板１０の所定領域にマスキングテープを貼り、透明基板１０の背面全体に着色層２０を形成した後に、マスキングテープを剥がすことで、マスキングテープが貼られていた所定領域を透過部１とし、透過部１を除く領域を遮光部２としてもよい。あるいは、例えば透明基板１０の背面全体に着色層２０を形成した後に、薬液を用いた処理やサンドブラスト処理等により着色層２０を除去することで、所定領域に透過部１を形成し、透過部１を除く領域を遮光部２としてもよい。 Further, for example, a masking tape is applied to a predetermined area of the transparent substrate 10, and the colored layer 20 is formed on the entire back surface of the transparent substrate 10, and then the masking tape is peeled off, so that the predetermined area where the masking tape has been applied is transferred to the transmission part 1 The region excluding the transmissive portion 1 may be the light shielding portion 2. Alternatively, for example, after the colored layer 20 is formed on the entire back surface of the transparent substrate 10, the colored layer 20 is removed by a treatment using a chemical solution, a sandblasting process, or the like, thereby forming the transmissive portion 1 in a predetermined region. The area except for the light shielding part 2 may be used.
　なお、遮光部２は、図１に示すように、透明基板１０の透過部１を除く全面に設けられてもよく、図３に示すように、透過部１の周囲部分にのみ設けられてもよい。なお、ここでいう全面とは、透明基板１０の周縁部分近傍に遮光部２が形成されないような場合も含み、実質的に全面に設けられている場合を含む。遮光部２が透過部１の周囲部分にのみ設けられる場合には、遮光部２の形状は矩形の枠状に限らず、任意の形状であってもよい。また、透過部１は、図４に示すように、透明基板１０の異なる位置に複数設けられてもよい。透過部１が複数設けられる場合には、各透過部１の背面に表示装置３０が接合される。 As shown in FIG. 1, the light shielding portion 2 may be provided on the entire surface of the transparent substrate 10 excluding the transmissive portion 1, or may be provided only on the peripheral portion of the transmissive portion 1 as shown in FIG. 3. Good. In addition, the whole surface here includes the case where the light-shielding part 2 is not formed in the vicinity of the peripheral portion of the transparent substrate 10, and includes the case where it is provided substantially over the entire surface. When the light shielding part 2 is provided only in the peripheral part of the transmission part 1, the shape of the light shielding part 2 is not limited to a rectangular frame shape, and may be an arbitrary shape. Further, as shown in FIG. 4, a plurality of transmission parts 1 may be provided at different positions on the transparent substrate 10. When a plurality of transmission parts 1 are provided, the display device 30 is bonded to the back surface of each transmission part 1.
　＜表示装置＞
　透明基板１０の透過部１の背面には、表示装置３０が設けられている。表示装置３０は、例えば液晶ディスプレイ装置、有機ＥＬディスプレイ装置、プラズマディスプレイ装置等である。表示装置３０は、例えば不図示の記憶装置に記憶されている画像や、ネットワークを介して接続するコンピュータやサーバ等から送信される画像を表示部３０ａに表示する。 <Display device>
A display device 30 is provided on the back surface of the transparent portion 1 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.
　表示装置３０は、図２に示すように、表示部３０ａと透明基板１０の透過部１の背面との間に充填される接着層１１により、透明基板１０の透過部１の背面に密接するように接合されている。 As shown in FIG. 2, the display device 30 is in close contact with the back surface of the transparent portion 10 of the transparent substrate 10 by the adhesive layer 11 filled between the display portion 30 a and the back surface of the transparent portion 10 of the transparent substrate 10. It is joined to.
　（接着層）
　表示装置３０と透明基板１０の透過部１との接合に用いられる接着層１１は、例えば液状の硬化性樹脂組成物の硬化物等である。例えば、透過部１の背面に未硬化の液状の硬化性樹脂組成物を塗布して表示装置３０を配置した後、液状の硬化性樹脂組成物を硬化させることで、表示装置３０を透明基板１０の透過部１に接着層１１を介して接合できる。 (Adhesive layer)
The adhesive layer 11 used for joining the display device 30 and the transmission part 1 of the transparent substrate 10 is, for example, a cured product of a liquid curable resin composition. For example, after applying the uncured liquid curable resin composition to the back surface of the transmissive portion 1 and disposing the display device 30, the liquid curable resin composition is cured, whereby the display device 30 is made transparent. It can be joined to the transmission part 1 of this through the adhesive layer 11.
　接着層１１は、２５℃で１Ｈｚにおける貯蔵せん断弾性率が、例えば１０３Ｐａ～１０７Ｐａであることが好ましく、１０３Ｐａ～１０５Ｐａであることがより好ましい。特に、接着層１１の２５℃で１Ｈｚにおける貯蔵せん断弾性率が１０３Ｐａ～１０５Ｐａである場合には、表示装置３０と透明基板１０との接合の際に生じ得る空隙を比較的容易に消失させることができる。 The adhesive layer 11 has a storage shear elastic modulus at 25 ° C. and 1 Hz of, for example, preferably 10 3 Pa to 10 7 Pa, and more preferably 10 3 Pa to 10 5 Pa. In particular, when the storage layer has a storage shear modulus of 10 3 Pa to 10 5 Pa at 25 ° C. and 1 Hz, it is relatively easy to form voids that may be generated when the display device 30 and the transparent substrate 10 are joined. Can be eliminated.
　接着層１１の厚さは、例えば０．０３ｍｍ～５ｍｍが好ましく、０．１ｍｍ～２ｍｍがより好ましい。接着層１１の厚さが０．０３ｍｍ以上であれば、透明基板１０の前面から外力等が加わった際に、接着層１１が外力による衝撃を十分に低減し、表示装置３０を保護できる。また、表示装置３０と透明基板１０との間に、接着層１１の厚さ未満の寸法の異物が混入しても、接着層１１の厚さが変化しないため、異物混入による視認性への影響が抑制される。また、表示装置３０の表示部３０ａの視認性が低下するため、接着層１１の厚さは５ｍｍ以下であることが好ましい。 The thickness of the adhesive layer 11 is preferably 0.03 mm to 5 mm, for example, and more preferably 0.1 mm to 2 mm. If the thickness of the adhesive layer 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 layer 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 dimension less than the thickness of the adhesive layer 11 is mixed between the display device 30 and the transparent substrate 10, the thickness of the adhesive layer 11 does not change. 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 contact bonding layer 11 is 5 mm or less.
　＜透過部、遮光部及び表示装置の構成＞
　本実施形態における透明基板１０は、図１，３，４に示すように、透過部１の面積が表示装置３０の表示部３０ａの面積よりも小さく、遮光部２が表示装置３０の外周縁及び表示部３０ａの外周縁を含む領域に設けられている。すなわち、表示装置３０は、表示部３０ａの面積が透過部１の面積よりも大きく、外周縁が透過部１の周囲に形成されている遮光部２に重なるように、透明基板１０の背面に接合されている。 <Configuration of transmission unit, light shielding unit, and display device>

And the design property of the transparent substrate 100 with a display apparatus improves. Further, since the outer peripheral edge of the display unit 30 a is not visible from the front surface of the transparent substrate 10, the image displayed on the display unit 30 a appears to float to the front side of the transparent substrate 10 from the user.
　上記した効果は、透明基板１０の厚さが３ｍｍ以上の場合に特に得られ易い。また、図１に示す表示装置３０の表示部３０ａの外周縁と遮光部２の内周縁との間隔Ｓは、全周にわたって１ｍｍ以上形成されることが好ましい。この場合において、間隔Ｓは全周において同じ大きさに設けられてもよく、部分的に異なる大きさに設けられてもよい。なお、表示装置３０の表示部３０ａの外周縁と遮光部２の内周縁との間隔Ｓは、透明基板１０の前面から斜めに表示部３０ａを見ても、表示部３０ａの外周縁が遮光部２の背後に隠れて見えないように、透明基板１０の厚さ等に応じて適宜設定される。 The effects described above are particularly easily obtained when the thickness of the transparent substrate 10 is 3 mm or more.

As shown in FIG. 1, the transmission unit 1, the light shielding unit 2, and the display device 30 are arranged so that the distance S between the outer peripheral edge of the display unit 30 a of the display device 30 and the inner peripheral edge of the light shielding unit 2 is 3 mm over the entire circumference. It is configured. With such a configuration, even when the display unit 30a is viewed obliquely from the front surface of the transparent substrate 10, the outer peripheral edge of the display unit 30a is hidden behind the light shielding unit 2 and is difficult to see. As a result, the image displayed on the display unit 30 a appears to the user to float on the front side of the transparent substrate 10.
　以上で説明したように、本実施形態に係る表示装置付き透明基板１００は、透明基板１０の背面に設けられる表示装置３０の外周縁及び表示部３０ａの外周縁を含む領域に遮光部２が形成されている。このような構成により、使用者からは、表示装置３０の表示部３０ａに表示される画像が透明基板１０の前面側に浮き上がるように見える。 As described above, in the transparent substrate 100 with a display device according to the present embodiment, the light shielding portion 2 is formed in a region including the outer periphery of the display device 30 and the outer periphery of the display unit 30a provided on the back surface of the transparent substrate 10. Has been. With such a configuration, it appears to the user that the image displayed on the display unit 30 a of the display device 30 is raised on the front side of the transparent substrate 10.

As shown in FIG. 6, in the transparent substrate 101 with a display device, the touch panel 40 is bonded to the transmission portion 1 of the transparent substrate 10 via the adhesive layer 11b. In the display device 30, the display unit 30 a is bonded to the back surface of the touch panel 40 (the surface opposite to the transparent substrate 10) via the adhesive layer 11 a. At this time, the adhesive layers 11a and 11b may be the same or different. The adhesive layer 11a preferably has a storage shear modulus at 25 ° C. and 1 Hz of, for example, 10 3 Pa to 10 7 Pa, and more preferably 10 3 Pa to 10 5 Pa.
　上記した表示装置付き透明基板１００は、図５に示すように、例えばテーブル２００の天板として使用されてもよい。テーブル２００は、例えば会議室等に設置され、表示装置３０の表示部３０ａに会議資料等が表示される。 The transparent substrate 100 with a display device described above may be used as a top plate of a table 200, for example, as shown in FIG. The table 200 is installed in a conference room or the like, for example, and conference materials and the like are displayed on the display unit 30a of the display device 30.
