　（本発明による第１の車両用表示機器について）
　以下、図面を参照して、本発明の一実施例について詳しく説明する。 (First display device for a vehicle according to the present invention)
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
　図１には、本発明による第１の車両用表示機器の模式的な断面図を示す。また、図２には、図１に示した第１の車両用表示機器の模式的な平面図を示す。なお、以下の記載では、一例として、第１の車両用表示機器１００が鉄道車両の窓ガラスに適用される場合を想定して、第１の車両用表示機器１００の構成および特徴について説明する。 FIG. 1 shows a schematic cross-sectional view of a first vehicle display device according to the present invention. FIG. 2 is a schematic plan view of the first vehicle display device shown in FIG. In the following description, as an example, the configuration and characteristics of the first vehicle display device 100 will be described assuming that the first vehicle display device 100 is applied to a window glass of a railway vehicle.
　図１および図２に示すように、この第１の車両用表示機器１００は、第１のガラス基板１１０と、第２のガラス基板１２０と、第１および第２のガラス基板の間に設けられた空間部１３０とを有する。 As shown in FIGS. 1 and 2, the first vehicle display device 100 is provided between a first glass substrate 110, a second glass substrate 120, and the first and second glass substrates. Space part 130.
　第１のガラス基板１１０は、第１の表面１１２および第２の表面１１４を有する。第１の車両用表示機器１００において、第１のガラス基板１１０は、第２の表面１１４の側が外側となるようにして配置される。同様に、第２のガラス基板１２０は、第３の表面１２２および第４の表面１２４を有する。第１の車両用表示機器１００において、第２のガラス基板１２０は、第４の表面１２４の側が外側となるようにして配置される。従って、空間部１３０は、第１のガラス基板１１０の第１の表面１１２と、第２のガラス基板１２０の第３の表面１２２との間に形成される。 The first glass substrate 110 has a first surface 112 and a second surface 114. In the first display apparatus for a vehicle 100, the first glass substrate 110 is arranged so that the second surface 114 side is the outside. Similarly, the second glass substrate 120 has a third surface 122 and a fourth surface 124. In the first display apparatus for a vehicle 100, the second glass substrate 120 is arranged such that the fourth surface 124 side is the outside. Accordingly, the space 130 is formed between the first surface 112 of the first glass substrate 110 and the third surface 122 of the second glass substrate 120.
　第２のガラス基板１２０の第３の表面１２２には、任意で、機能膜１４０が設置されても良い。機能膜１４０の種類は、特に限られない。機能膜１４０は、例えば、熱線反射膜、ＵＶ吸収膜およびＵＶ反射膜等であっても良い。ただし、この機能膜１４０の設置は、必ずしも必要ではない。 A functional film 140 may optionally be provided on the third surface 122 of the second glass substrate 120. The type of the functional film 140 is not particularly limited. The functional film 140 may be, for example, a heat ray reflective film, a UV absorbing film, a UV reflective film, or the like. However, the installation of the functional film 140 is not always necessary.
　空間部１３０は、周囲がスペーサ材１５０で密閉されており、これにより、空間部１３０が外部環境と遮断される。空間部１３０内には、気体が充填される。気体の種類は、従来の複層ガラスの空間部に充填され得るガスであれば、特に限られない。空間部１３０内には、例えば、（乾燥）空気または（乾燥）不活性ガスが充填されても良い。 The space portion 130 is hermetically sealed with a spacer material 150, thereby blocking the space portion 130 from the external environment. The space 130 is filled with gas. The kind of gas will not be restricted especially if it is the gas which can be filled in the space part of the conventional multilayer glass. The space 130 may be filled with, for example, (dry) air or (dry) inert gas.
　このような第１の車両用表示機器１００が、例えば鉄道車両の窓ガラス等に適用される場合、第１のガラス基板１１０の側が内側、すなわち車内側となり、第２のガラス基板の側が外側、すなわち車外側となる。 When such a first vehicle display device 100 is applied to, for example, a window glass of a railway vehicle, the first glass substrate 110 side is the inside, that is, the vehicle interior side, and the second glass substrate side is the outside. That is, it is the vehicle exterior side.
　ここで、第１の車両用表示機器１００は、さらに、空間部１３０内に配置された表示装置１７０を有する。 Here, the first vehicle display device 100 further includes a display device 170 arranged in the space 130.
　表示装置１７０は、第１のガラス基板１１０の第１の表面１１２に配置される。また、表示装置１７０は、第１のガラス基板１１０の側が表示面側となるようにして、配置される。従って、表示装置１７０がオン状態のときには、乗客は、第１のガラス基板１１０の側（すなわち車内側）から、表示装置１７０が表示する画像または映像等を視認することができる。 The display device 170 is disposed on the first surface 112 of the first glass substrate 110. In addition, the display device 170 is arranged such that the first glass substrate 110 side is the display surface side. Therefore, when the display device 170 is in the on state, the passenger can visually recognize an image or video displayed on the display device 170 from the first glass substrate 110 side (that is, the vehicle interior side).
　表示装置１７０の第１のガラス基板１１０の第１の表面１１２への取り付け方法は、特に限られない。表示装置１７０は、例えば、透明な接着材または透明粘着テープ等を用いて、第１のガラス基板１１０の第１の表面１１２に貼り付けても良い。 The method for attaching the display device 170 to the first surface 112 of the first glass substrate 110 is not particularly limited. The display device 170 may be attached to the first surface 112 of the first glass substrate 110 using, for example, a transparent adhesive or a transparent adhesive tape.
　ガラス基板１１０において、表示装置１７０が貼り付けされた周縁部には黒色のセラミック焼成による印刷膜が形成されても良い。これにより、車内側からは表示装置に付属する部材等が見なくなり、美観に優れる。 In the glass substrate 110, a printed film by black ceramic firing may be formed on the peripheral edge of the display device 170 attached. Thereby, the members attached to the display device are not seen from the inside of the vehicle, and the aesthetic appearance is excellent.
　このように構成された第１の車両用表示機器１００を鉄道車両の窓ガラス等に適用した場合、開閉扉の上部にのみ表示装置を設けた場合に比べて、より多くの客室内の乗客が、表示装置を視認することが可能になる。従って、第１の車両用表示機器１００では、より多くの乗客に対して、各種情報を提供することが可能となる。 When the first vehicle display device 100 configured in this way is applied to a window glass or the like of a railway vehicle, more passengers in the cabin than in a case where a display device is provided only at the upper part of the door. The display device can be visually recognized. Therefore, the first vehicle display device 100 can provide various types of information to more passengers.
　ここで、図２の例では、第１の車両用表示機器１００は、表示装置１７０として、単一の表示装置１７０を備える。ただし、表示装置１７０の数は、特に限られない。表示装置１７０の数は、２つ以上、例えば３つであっても良い。表示装置１７０の数は、例えば、第１のガラス基板１１０の寸法、および表示装置１７０の寸法等に応じて、自由に選択することができる。 Here, in the example of FIG. 2, the first vehicular display device 100 includes a single display device 170 as the display device 170. However, the number of display devices 170 is not particularly limited. The number of display devices 170 may be two or more, for example, three. The number of display devices 170 can be freely selected according to, for example, the dimensions of the first glass substrate 110 and the dimensions of the display device 170.
　また、第１のガラス基板１１０に対する表示装置１７０の配置位置は、特に限られない。ただし、表示装置１７０は、図２に示すように、第１の車両用表示機器１００の上部の端面１０２の近傍に配置することが好ましい。これにより、表示装置１７０に接続される配線類を目立たなくすることができる。また、座席に座った乗客によって、表示装置１７０が陰になることを有意に回避することができる。さらに、ガラス基板１１０全面のうち一部の面に表示装置１７０が配置されることが好ましい。これにより、表示情報だけでなく車窓からの外観を損なうことがない。特に、ガラス基板１１０全面のうち２～４０％の部分に表示装置１７０が配置されることが好ましい。より好ましくは１０～３０％である。 Further, the arrangement position of the display device 170 with respect to the first glass substrate 110 is not particularly limited. However, the display device 170 is preferably disposed in the vicinity of the upper end surface 102 of the first vehicular display device 100 as shown in FIG. Thereby, the wiring connected to the display device 170 can be made inconspicuous. Further, it is possible to significantly avoid the display device 170 from being shaded by a passenger sitting in the seat. Furthermore, the display device 170 is preferably disposed on a part of the entire surface of the glass substrate 110. Thereby, not only the display information but also the appearance from the vehicle window is not impaired. In particular, it is preferable that the display device 170 is disposed on a portion of 2 to 40% of the entire surface of the glass substrate 110. More preferably, it is 10 to 30%.
　第１のガラス基板の車内側面には反射防止処理がなされていることが好ましい。少なくとも表示部材の画像が表示される部分には反射防止処理がなされていることが好ましい。反射防止処理は、例えば反射防止層のコーティング等でなされる。また、表示装置１７０が複数存在する場合も、その配置形態は、特に限られない。例えば、各表示装置１７０は、水平方向に沿って、一列に配置されても良い。この場合も、前述のように、各表示装置１７０は、第１の車両用表示機器１００の上部の辺１０２の近傍に配置することが好ましい。なお、表示装置１７０を複数配置する場合、上述のように１枚のガラス基板１７０に配置することも、複数のガラス基板に１つずつ配置しこのガラス基板を並列配置することもできる。どちらの場合でも、ガラス基板の全面に対する表示装置の占有面積割合は、先に述べた２～４０％が好ましい。より好ましくは１０～３０％である。 It is preferable that an antireflection treatment is performed on the inner side surface of the first glass substrate. It is preferable that at least a portion where an image of the display member is displayed is subjected to an antireflection treatment. The antireflection treatment is performed, for example, by coating an antireflection layer. Also, when there are a plurality of display devices 170, the arrangement form is not particularly limited. For example, the display devices 170 may be arranged in a line along the horizontal direction. Also in this case, as described above, each display device 170 is preferably arranged in the vicinity of the upper side 102 of the first vehicle display device 100. When a plurality of display devices 170 are arranged, they can be arranged on one glass substrate 170 as described above, or can be arranged one by one on a plurality of glass substrates and arranged in parallel. In either case, the ratio of the area occupied by the display device to the entire surface of the glass substrate is preferably 2 to 40% as described above. More preferably, it is 10 to 30%.
　（本発明による第２の車両用表示機器について）
　次に、図３を参照して、本発明による第２の車両用表示機器について説明する。 (About the 2nd display apparatus for vehicles by this invention)
Next, with reference to FIG. 3, the 2nd display apparatus for vehicles by this invention is demonstrated.
　図３には、本発明による第２の車両用表示機器の模式的な断面図を示す。なお、ここでも、以下の記載では、一例として、第２の車両用表示機器２００が鉄道車両の窓ガラスに適用される場合を想定して、第２の車両用表示機器２００の構成および特徴について説明する。 FIG. 3 shows a schematic cross-sectional view of a second vehicle display device according to the present invention. Also in this case, in the following description, as an example, assuming the case where the second vehicle display device 200 is applied to a window glass of a railway vehicle, the configuration and characteristics of the second vehicle display device 200 are described. explain.
　図３に示すように、この第２の車両用表示機器２００は、基本的に、図１に示した第１の車両用表示機器１００と同様の構成を有する。従って、第２の車両用表示機器２００において、第１の車両用表示機器１００と同様の部材には、図１に示した参照符号に１００を加えた参照符号が付されている。 As shown in FIG. 3, the second vehicle display device 200 basically has the same configuration as the first vehicle display device 100 shown in FIG. Therefore, in the second vehicle display device 200, the same reference numerals as those in the first vehicle display device 100 are given reference numerals obtained by adding 100 to the reference numerals shown in FIG.
　なお、第２の車両用表示機器２００においても、第２のガラス基板２２０の第３の表面２２２に設けられた機能膜２４０は、任意に設置されるものであり、必須の構成部材ではない。 In the second vehicle display device 200, the functional film 240 provided on the third surface 222 of the second glass substrate 220 is arbitrarily installed and is not an essential component.
　ここで、この第２の車両用表示機器２００は、第２のガラス基板２２０の第３の表面２２２側に、さらに不透明部材２７５が設置されている点が、第１の車両用表示機器１００とは異なっている。 Here, the second vehicle display device 200 is different from the first vehicle display device 100 in that an opaque member 275 is further provided on the third surface 222 side of the second glass substrate 220. Is different.
　この不透明部材２７５は、第２の車両用表示機器２００を車両の外側（すなわち第２のガラス基板２２０の側）から見たとき、表示装置２７０と対応する位置に配置される。例えば、不透明部材２７５は、表示装置２７０よりも一回り大きな寸法で配置されても良い。 The opaque member 275 is disposed at a position corresponding to the display device 270 when the second vehicle display device 200 is viewed from the outside of the vehicle (that is, the second glass substrate 220 side). For example, the opaque member 275 may be arranged with a size slightly larger than that of the display device 270.
　このような不透明部材２７５の設置により、表示装置２７０に対し陰となり、鉄道車両の外側にいる人が第２の車両用表示機器２００を眺めた際に、表示装置２７０の背面が視認されにくくなる。これにより、表示装置２７０の背面が露呈して、第２の車両用表示機器２００、さらには鉄道車両の美感が損なわれることを有意に抑制することができる。 With the installation of the opaque member 275, the display device 270 is shaded, and when a person outside the railway vehicle views the second vehicle display device 200, the back surface of the display device 270 is not easily seen. . Thereby, it can suppress significantly that the back surface of the display apparatus 270 is exposed and the aesthetics of the 2nd display apparatus 200 for vehicles, and also a rail vehicle are impaired.
　不透明部材２７５の形態は、特に限られない。不透明部材２７５は、例えば、有機インクまたはセラミック小生による印刷膜や、ステッカー等であっても良い。 The form of the opaque member 275 is not particularly limited. The opaque member 275 may be, for example, a printed film made of organic ink or ceramic elementary school, a sticker, or the like.
　（本発明の一実施例による車両用表示機器の適用例について）
　図４には、本発明の一実施例による車両用表示機器４００（第３の車両用表示機器）を鉄道車両の窓ガラスに適用した例を概略的に示す。図４は、車両用表示機器４００を鉄道車両の内側、すなわち客室４０１側から見た状態を示している。 (Application example of vehicle display device according to one embodiment of the present invention)
FIG. 4 schematically shows an example in which a vehicle display device 400 (third vehicle display device) according to an embodiment of the present invention is applied to a window glass of a railway vehicle. FIG. 4 shows a state in which the vehicle display device 400 is viewed from the inside of the railway vehicle, that is, from the cabin 401 side.
　第３の車両用表示機器４００は、例えば金属製の枠部材４０５で囲まれた空間に配置される。 The third vehicle display device 400 is disposed in a space surrounded by a metal frame member 405, for example.
　第３の車両用表示機器４００は、基本的に、前述の図１および図２に示した第１の車両用表示機器１００と同様の構成を有する。従って、第３の車両用表示機器４００において、第１の車両用表示機器１００と同様の部材には、図１に示した参照符号に３００を加えた参照符号が付されている。 The third vehicle display device 400 basically has the same configuration as the first vehicle display device 100 shown in FIGS. 1 and 2 described above. Accordingly, in the third vehicle display device 400, the same reference numerals as those in the first vehicle display device 100 are given reference numerals obtained by adding 300 to the reference numerals shown in FIG. 1.
　ただし、図４の例では、第３の車両用表示機器４００は、３つの表示装置４７０ａ、４７０ｂ、４７０ｃを有する。これらの表示装置４７０ａ、４７０ｂ、４７０ｃは、車両用表示機器４００の上部の辺近傍、すなわち上部の枠部材４０５の直下に、一列に沿って配置されている。 However, in the example of FIG. 4, the third vehicle display device 400 includes three display devices 470a, 470b, and 470c. These display devices 470a, 470b, and 470c are arranged along a line near the upper side of the display device for vehicles 400, that is, immediately below the upper frame member 405.
　前述の第１の車両用表示機器１００の場合と同様、車両用表示機器４００は、第１のガラス基板４１０の側が客室４０１の側（すなわち乗客側）となるようにして、鉄道車両に設置される。従って、客室４０１内の乗客は、表示装置４７０ａ、４７０ｂ、４７０ｃに表示される表示物を視認することができる。 As in the case of the first vehicle display device 100 described above, the vehicle display device 400 is installed in a railway vehicle such that the first glass substrate 410 side is the cabin 401 side (that is, the passenger side). The Therefore, the passengers in the cabin 401 can visually recognize the display objects displayed on the display devices 470a, 470b, and 470c.
　表示装置４７０ａ、４７０ｂ、４７０ｃに表示される表示物の態様は、特に限られないが、例えば、文字情報、画像または映像等であっても良い。例えば、表示装置４７０ａ、４７０ｂ、４７０ｃには、窓の外に見える様々なランドマーク等の地理上の特徴物を案内する情報等を表示しても良い。あるいは、表示装置４７０ａ、４７０ｂ、４７０ｃには、各種宣伝公告、または電車の運行情報等のニュース情報などを表示しても良い。 The display object displayed on the display devices 470a, 470b, 470c is not particularly limited, and may be, for example, character information, an image, a video, or the like. For example, the display devices 470a, 470b, and 470c may display information that guides geographical features such as various landmarks that are visible outside the window. Alternatively, various advertising announcements or news information such as train operation information may be displayed on the display devices 470a, 470b, and 470c.
　また、各表示装置４７０ａ、４７０ｂ、４７０ｃに同一時間に表示される表示物は、同一であっても、異なっていても良い。後者の場合、例えば、図４において、左から右、または右から左に向かって、像が連続的に変化するようにして、各表示装置４７０ａ、４７０ｂ、４７０ｃにわたって、一連の画像または映像を表示しても良い。 Further, the display objects displayed on the display devices 470a, 470b, and 470c at the same time may be the same or different. In the latter case, for example, in FIG. 4, a series of images or videos are displayed over the display devices 470a, 470b, and 470c so that the images continuously change from left to right or from right to left. You may do it.
　前述のように、車両用表示機器４００を鉄道車両の窓ガラスに適用した場合、従来のような開閉扉の上部にのみ表示装置を配置した場合に比べて、より多くの乗客に対して、画像または映像のような表示物を提供することが可能となる。 As described above, when the vehicular display device 400 is applied to a window glass of a railway vehicle, the image is obtained for more passengers than in the case where a display device is disposed only on the upper part of a conventional open / close door. Alternatively, a display object such as a video can be provided.
　（車両用表示機器の各構成部材について）
　次に、本発明の一実施例による車両用表示機器に含まれる各構成部材の仕様等について、簡単に説明する。なお、ここでは、図３に示した第２の車両用表示機器２００を例に、その構成部材について説明する。ただし、以下の記載が第１の車両用表示機器１００および第３の車両用表示機器４００を構成する構成部材にも、同様に適用し得ることは当業者には明らかである。また、以下の説明において、記載を明確にするため、各部材には、図３に示した参照符号を使用する。 (About each structural member of the display device for vehicles)
Next, the specifications and the like of each component included in the vehicle display device according to the embodiment of the present invention will be briefly described. Here, the constituent members will be described by taking the second vehicle display device 200 shown in FIG. 3 as an example. However, it will be apparent to those skilled in the art that the following description can be similarly applied to the components constituting the first vehicle display device 100 and the third vehicle display device 400. Further, in the following description, the reference numerals shown in FIG. 3 are used for the respective members in order to clarify the description.
　（第１および第２のガラス基板２１０、２２０）
　第１のガラス基板２１０の寸法は、特に限られない。第１のガラス基板２１０の寸法は、車両用表示機器２００が適用される部位に応じて、自由に選定できる。例えば、第１のガラス基板２１０の厚さは、１ｍｍ～５ｍｍ程度であっても良い。 (First and second glass substrates 210 and 220)
The dimension of the first glass substrate 210 is not particularly limited. The dimension of the 1st glass substrate 210 can be freely selected according to the site | part to which the vehicle display apparatus 200 is applied. For example, the thickness of the first glass substrate 210 may be about 1 mm to 5 mm.
　第１のガラス基板２１０のガラス組成は、特に限られない。第１のガラス基板２１０は、例えば、ソーダライムガラス、無アルカリガラス、アルミノシリケートガラス、または有機ガラス等であっても良い。 The glass composition of the first glass substrate 210 is not particularly limited. The first glass substrate 210 may be, for example, soda lime glass, alkali-free glass, aluminosilicate glass, or organic glass.
　なお、第１のガラス基板２１０の少なくとも一方の表面は、化学強化処理または物理強化処理されていても良い。 Note that at least one surface of the first glass substrate 210 may be subjected to chemical strengthening treatment or physical strengthening treatment.
　ここで「化学強化処理（法）」とは、ガラス材料をアルカリ金属を含む溶融塩中に浸漬させ、ガラス材料の最表面に存在する原子径の小さなアルカリ金属（イオン）を、溶融塩中に存在する原子径の大きなアルカリ金属（イオン）と置換する技術の総称を言う。「化学強化処理（法）」では、処理されたガラス材料の表面には、元の原子よりも原子径の大きなアルカリ金属（イオン）が配置される。このため、ガラス材料の表面に圧縮応力を付与することができ、これによりガラス材料の強度が向上する。 Here, “chemical strengthening treatment (method)” means that a glass material is immersed in a molten salt containing an alkali metal, and an alkali metal (ion) having a small atomic diameter present on the outermost surface of the glass material is introduced into the molten salt. This is a generic term for technologies that replace existing alkali metals (ions) with a large atomic diameter. In the “chemical strengthening treatment (method)”, an alkali metal (ion) having an atomic diameter larger than that of the original atom is disposed on the surface of the treated glass material. For this reason, compressive stress can be applied to the surface of the glass material, thereby improving the strength of the glass material.
　例えば、第１のガラス基板２１０がナトリウム（Ｎａ）を含む場合、化学強化処理により、このナトリウムは、例えばカリウム（Ｋ）と置換される。あるいは、例えば、第１のガラス基板２１０がリチウム（Ｌｉ）を含む場合、化学強化処理により、このリチウムは、例えばナトリウム（Ｎａ）および／またはカリウム（Ｋ）と置換されても良い。 For example, when the first glass substrate 210 contains sodium (Na), this sodium is replaced with, for example, potassium (K) by the chemical strengthening treatment. Alternatively, for example, when the first glass substrate 210 contains lithium (Li), this lithium may be replaced with, for example, sodium (Na) and / or potassium (K) by chemical strengthening treatment.
　また、「物理強化処理（法）」とは、ガラス材料を高温の「飴」状の状態から急冷することにより、ガラス材料内に残留応力分布を形成する技術を言う。通常の場合、ガラス材料の内部は、表面に比べて急冷の影響を受けにくく、比較的ゆっくりと降温固化される。このため、急冷中は、ガラス材料の内部から表面に向かって、残留圧縮応力が大きくなり、残留圧縮応力の深さ方向プロファイルが得られる。最終的に得られるガラス材料の表面には、比較的深い厚さで圧縮応力層が形成され、これにより物理強化処理前に比べて、ガラス材料の強度が向上する。 Also, “physical strengthening treatment (method)” refers to a technique for forming a residual stress distribution in a glass material by rapidly cooling the glass material from a high-temperature “飴” state. In the normal case, the inside of the glass material is less susceptible to rapid cooling than the surface, and is cooled and solidified relatively slowly. For this reason, during rapid cooling, the residual compressive stress increases from the inside to the surface of the glass material, and a depth direction profile of the residual compressive stress is obtained. On the surface of the glass material finally obtained, a compressive stress layer is formed with a relatively deep thickness, whereby the strength of the glass material is improved as compared with that before the physical strengthening treatment.
　化学強化処理および物理強化処理される領域は、特に限られない。例えば、第１のガラス基板２１０は、実質的に、露出表面全体が強化処理されても良い。また、例えば、第１のガラス基板２１０は、第１の表面２１２および第２の表面２１４のうちの一方の表面のみが強化処理されても良い。 The area subjected to chemical strengthening processing and physical strengthening processing is not particularly limited. For example, the entire first exposed surface of the first glass substrate 210 may be tempered. Further, for example, the first glass substrate 210 may be subjected to a tempering process only on one of the first surface 212 and the second surface 214.
　第１のガラス基板２１０に対してこのような表面強化処理を実施することにより、第１のガラス基板２１０の強度が向上する。また、第１のガラス基板２１０の厚さを、より薄くすることができる。 The strength of the first glass substrate 210 is improved by performing such a surface strengthening process on the first glass substrate 210. In addition, the thickness of the first glass substrate 210 can be further reduced.
　また、第１のガラス基板２１０は、必ずしも単一の部材で形成する必要はない。例えば、第１のガラス基板２１０は、合わせガラスであっても良い。そのような合わせガラスは、２枚のガラス板をフィルムまたは中間膜を介して貼り合わせることにより構成される。表示装置２７０が配置される第１のガラス基板２１０は、合わせガラスであることが好ましい。この場合、万一ガラスが破損しても、表示装置２７０の脱落、落下等が防止でき、安全に各種情報を提供できる。 In addition, the first glass substrate 210 is not necessarily formed of a single member. For example, the first glass substrate 210 may be laminated glass. Such a laminated glass is comprised by bonding together two glass plates through a film or an intermediate film. The first glass substrate 210 on which the display device 270 is disposed is preferably laminated glass. In this case, even if the glass is broken, the display device 270 can be prevented from falling off or falling, and various information can be provided safely.
　第２のガラス基板２２０についても、第１のガラス基板２１０と同様のものが使用できる。なお、第１のガラス基板２１０と第２のガラス基板２２０の材質、寸法（厚さ）、および物性等は、同一であっても、異なっていても良い。 As the second glass substrate 220, the same one as the first glass substrate 210 can be used. Note that the materials, dimensions (thickness), physical properties, and the like of the first glass substrate 210 and the second glass substrate 220 may be the same or different.
　（表示装置２７０）
　第２の車両用表示機器２００に使用される表示装置２７０の種類は、特に限られない。表示装置２７０は、例えば、液晶ディスプレイ装置、プラズマディスプレイ装置、または有機ＥＬディスプレイ装置等であっても良い。 (Display device 270)
The type of the display device 270 used for the second vehicle display device 200 is not particularly limited. The display device 270 may be, for example, a liquid crystal display device, a plasma display device, or an organic EL display device.
　また、表示装置２７０の寸法は、特に限られないが、あまりに大きな寸法の場合、重量が大きくなり、第１のガラス基板２１０に取り付けることが難しくなる。表示装置２７０の寸法は、例えば、１０インチ～４６インチの範囲である。 Further, the size of the display device 270 is not particularly limited, but if the size is too large, the weight increases and it is difficult to attach to the first glass substrate 210. The size of the display device 270 is, for example, in the range of 10 inches to 46 inches.
　なお、表示装置２７０の厚さ（図３におけるＸ方向の長さ）は、空間部２３０の厚さ（図３におけるＸ方向の長さ）よりも薄いことが好ましい。表示装置２７０の厚さが空間部２３０の厚さと実質的に等しい場合、表示装置２７０の背面に隙間がなくなるため、振動等が生じた際に、表示装置２７０が第２のガラス基板２２０と当接して、第２のガラス基板２２０が損傷を受ける可能性がある。 Note that the thickness of the display device 270 (the length in the X direction in FIG. 3) is preferably thinner than the thickness of the space 230 (the length in the X direction in FIG. 3). When the thickness of the display device 270 is substantially equal to the thickness of the space portion 230, there is no gap on the back surface of the display device 270, so that when the vibration or the like occurs, the display device 270 contacts the second glass substrate 220. In contact therewith, the second glass substrate 220 may be damaged.
　第１のガラス基板２１０、さらには第２の車両用表示機器２００に対する表示装置２７０の設置位置は、特に限られないが、前述のように、表示装置２７０は、第２の車両用表示機器２００の上部の辺の近傍、すなわち、上部スペーサ材２５０の直下に配置することが好ましい。これにより、表示装置２７０に接続される配線類を目立たなくすることができる。また、座席に座った乗客によって、表示装置２７０が陰になることを有意に回避することができる。 Although the installation position of the display device 270 with respect to the first glass substrate 210 and further to the second vehicle display device 200 is not particularly limited, as described above, the display device 270 includes the second vehicle display device 200. It is preferable to dispose near the upper side of the upper spacer material 250, that is, immediately below the upper spacer material 250. Thereby, wirings connected to the display device 270 can be made inconspicuous. In addition, it is possible to significantly avoid the display device 270 being shaded by a passenger sitting in the seat.
　表示装置２７０の第１のガラス基板２１０への取り付け方法は、特に限られない。表示装置２７０は、例えば、透明接着材または透明粘着テープ等を用いて、第１のガラス基板２１０の第１の表面２１２に取り付けても良い。ここで、表示装置２７０の画像表示部の全体を覆うように透明接着材を使用してガラス基板２１０へ接合することにより、表示装置２７０とガラス基板２１０との間に空隙がなくなり、美観良く各種情報を提供することが可能となる。 The method for attaching the display device 270 to the first glass substrate 210 is not particularly limited. The display device 270 may be attached to the first surface 212 of the first glass substrate 210 using, for example, a transparent adhesive or a transparent adhesive tape. Here, by bonding to the glass substrate 210 using a transparent adhesive so as to cover the entire image display portion of the display device 270, there is no gap between the display device 270 and the glass substrate 210, and various types of aesthetically pleasing. Information can be provided.
　透明接着材は、例えば、透明樹脂で構成されても良い。透明接着材は、例えば、液状の硬化性樹脂組成物を硬化することにより、形成されても良い。 The transparent adhesive may be made of a transparent resin, for example. The transparent adhesive may be formed, for example, by curing a liquid curable resin composition.
　この場合、第１のガラス基板２１０の第１の表面２１２上に未硬化の樹脂組成物を塗布し、さらに樹脂組成物上に表示装置２７０を配置した後、樹脂組成物を硬化させることにより、第１のガラス基板２１０と表示装置２７０とが接合される。 In this case, by applying an uncured resin composition on the first surface 212 of the first glass substrate 210 and further disposing the display device 270 on the resin composition, the resin composition is cured, The first glass substrate 210 and the display device 270 are bonded.
　透明接着材は、２５℃におけるせん断弾性率が、１０３Ｐａ～１０７Ｐａの範囲であることが好ましく、１０４Ｐａ～１０６Ｐａの範囲であることがより好ましい。特に、透明接着材の２５℃におけるせん断弾性率が１０４Ｐａ～１０５Ｐａの範囲である場合、第１のガラス基板２１０および表示装置２７０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 transparent adhesive preferably has a shear modulus at 25 ° C. in the range of 10 3 Pa to 10 7 Pa, and more preferably in the range of 10 4 Pa to 10 6 Pa. In particular, when the shear elastic modulus at 25 ° C. of the transparent adhesive is in the range of 10 4 Pa to 10 5 Pa, the voids that can be generated when the first glass substrate 210 and the display device 270 are joined are relatively easy. Can be eliminated.
　２５℃におけるせん断弾性率が１０３Ｐａ以上の場合、透明接着材の形状を適正に維持できる。また、透明接着材の厚さが比較的厚い場合であっても、透明接着材全体で厚さを均一に維持することができ、第１のガラス基板２１０と表示装置２７０を接合する際に、表示装置２７０と透明接着材との界面に、空隙が発生し難くなる。 When the shear modulus at 25 ° C. is 10 3 Pa or more, the shape of the transparent adhesive can be properly maintained. Further, even when the thickness of the transparent adhesive is relatively thick, the thickness can be kept uniform throughout the transparent adhesive, and when the first glass substrate 210 and the display device 270 are joined, Gaps are less likely to occur at the interface between the display device 270 and the transparent adhesive.
　また、透明接着材の２５℃におけるせん断弾性率が１０４Ｐａ以上の場合、透明接着材の変形を有意に抑制することができる。透明接着材のせん断弾性率が１０７Ｐａ以下の場合、第１のガラス基板２１０と表示装置２７０とを接合した際に、透明接着材が良好な密着性を発揮できる。 Moreover, when the shear elastic modulus at 25 ° C. of the transparent adhesive is 10 4 Pa or more, the deformation of the transparent adhesive can be significantly suppressed. When the shear elastic modulus of the transparent adhesive is 10 7 Pa or less, the transparent adhesive can exhibit good adhesion when the first glass substrate 210 and the display device 270 are joined.
　透明接着材の厚さは、０．０３ｍｍ～２ｍｍが好ましく、０．１ｍｍ～０．８ｍｍがより好ましい。 The thickness of the transparent adhesive is preferably 0.03 mm to 2 mm, more preferably 0.1 mm to 0.8 mm.
　透明接着材の厚さが０．０３ｍｍ以上の場合、第１のガラス基板２１０の外側から第２の車両用表示機器２００に向かって外力等が加わった際に、透明接着材によって、外力による衝撃を有効に低減することができ、これにより、表示装置２７０を適正に保護することが可能となる。また、第１のガラス基板２１０と表示装置２７０の間に、透明接着材の厚さ未満の寸法の異物が混入しても、透明接着材の厚さがあまり変化しないため、異物混入による光透過性能への影響を有意に抑制することができる。また、透明接着材の厚さが２ｍｍ以下の場合、透明接着材による表示装置２７０部分の厚さの上昇を、有意に抑制することができる。 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 first glass substrate 210 toward the second vehicle display device 200, the impact due to the external force is caused by the transparent adhesive. As a result, the display device 270 can be appropriately protected. In addition, even if a foreign substance having a dimension less than the thickness of the transparent adhesive is mixed between the first glass substrate 210 and the display device 270, the thickness of the transparent adhesive does not change so much, so that light transmission due to the foreign substance mixed in The influence on performance can be significantly suppressed. Moreover, when the thickness of a transparent adhesive is 2 mm or less, the raise of the thickness of the display apparatus 270 part by a transparent adhesive can be suppressed significantly.
　なお、透明接着材は、単一の層としてではなく、平面視中央部分の層状部と、該層状部の周囲を取り囲む堰状部とで構成されても良い。堰状部は、例えば、第１のガラス基板２１０上で、液状の硬化性樹脂組成物から透明接着材を形成する際に、硬化性樹脂組成物が第１の表面２１２上で所定の範囲を超えて、外方に広がることを抑制する役割（すなわち、層状部用の液状の硬化性樹脂組成物の流出を堰き止める役割）を有する。 Note that the transparent adhesive material may be composed of a layered portion at a central portion in plan view and a weir-shaped portion surrounding the periphery of the layered portion, not as a single layer. For example, when the transparent portion is formed from the liquid curable resin composition on the first glass substrate 210, the weir-shaped portion has a predetermined range on the first surface 212. Beyond, it has a role of suppressing outward spreading (that is, a role of blocking outflow of the liquid curable resin composition for the layered portion).
　堰状部は、中央部分の層状部を構成する硬化性樹脂組成物とは異なる硬化性樹脂組成物を硬化させることにより、構成されても良い。 The weir-like portion may be constituted by curing a curable resin composition different from the curable resin composition constituting the layered portion of the central portion.
　（機能膜２４０）
　必要に応じて、第２のガラス基板２２０の第３の表面２２２の少なくとも一部には、機能膜２４０が設置されても良い。 (Functional membrane 240)
The functional film 240 may be provided on at least a part of the third surface 222 of the second glass substrate 220 as necessary.
　機能膜２４０の種類は、特に限られない。機能膜２４０は、例えば、熱線反射膜、ＵＶ吸収膜およびＵＶ線反射膜等であっても良い。熱線反射膜は、空間部の温度上昇を抑制し、表示装置２７０が故障なく各種情報を提供できる点で好ましい。 The type of the functional film 240 is not particularly limited. The functional film 240 may be, for example, a heat ray reflecting film, a UV absorbing film, a UV ray reflecting film, or the like. The heat ray reflective film is preferable in that the temperature rise in the space is suppressed, and the display device 270 can provide various information without failure.
　機能膜２４０を設置することにより、第２の車両用表示機器２００に、各種機能を付与することができる。 By installing the functional film 240, various functions can be imparted to the second vehicle display device 200.
　なお、これに加えてまたはこれとは別に、第１のガラス基板２１０の第１の表面２１２および／または第２の表面２１４に、第２の機能膜を設置しても良い。ただし、第１のガラス基板２１０の第１の表面２１２に第２の機能膜を設置する場合、表示装置２７０が設置されている領域以外の領域に、第２の機能膜を設置することが好ましい。 In addition to this, or alternatively, the second functional film may be provided on the first surface 212 and / or the second surface 214 of the first glass substrate 210. However, when the second functional film is installed on the first surface 212 of the first glass substrate 210, it is preferable to install the second functional film in a region other than the region where the display device 270 is installed. .
　（不透明部材２７５）
　必要に応じて、第２のガラス基板２２０の第３の表面２２２の少なくとも一部に、不透明部材２７５が設置される。なお、第２のガラス基板２２０の第３の表面２２２に機能膜２４０が存在する場合、不透明部材２７５は、機能膜２４０の上部に配置される。あるいは、機能膜２４０が、不透明部材２７５としての役割を兼ねても良い。 (Opaque member 275)
An opaque member 275 is installed on at least a part of the third surface 222 of the second glass substrate 220 as necessary. When the functional film 240 exists on the third surface 222 of the second glass substrate 220, the opaque member 275 is disposed on the functional film 240. Alternatively, the functional film 240 may also serve as the opaque member 275.
　不透明部材２７５を設置することにより、鉄道車両の外側にいる人が第２の車両用表示機器２００を眺めた際に、表示装置２７０の背面が視認されにくくなる。これにより、第２の車両用表示機器２００の美感が向上する。なお、この目的のため、不透明部材２７５の寸法は、第２の車両用表示機器２００を第２のガラス基板２２０の側から見たとき、表示装置２７０よりも少なくとも一回り大きな寸法であることが好ましく、不透明部材２７５の面積が、表示装置２７０の面積よりも１．０５～１．３倍大きいことがより好ましい。 By installing the opaque member 275, when a person outside the railway vehicle looks at the second vehicle display device 200, the back surface of the display device 270 is hardly visible. Thereby, the aesthetics of the 2nd display apparatus 200 for vehicles improve. For this purpose, the dimension of the opaque member 275 may be at least one dimension larger than that of the display device 270 when the second vehicle display device 200 is viewed from the second glass substrate 220 side. Preferably, the area of the opaque member 275 is 1.05-1.3 times larger than the area of the display device 270.
　不透明部材２７５の種類および設置方法は、特に限られない。不透明部材２７５は、例えば、有機インクまたはセラミック焼成による印刷膜や、貼付されたステッカー等であっても良い。 The type and installation method of the opaque member 275 are not particularly limited. The opaque member 275 may be, for example, a printed film by organic ink or ceramic baking, an attached sticker, or the like.
　印刷膜は、例えば、スクリーン印刷法またはインクジェット印刷法等により、第２のガラス基板２２０の第３の表面２２２に設置しても良い。セラミック焼成による印刷膜は、例えば、顔料または染料を含有するガラスフリットをスクリーン印刷で、第２のガラス基板２２０の第３の表面２２２にスラリーを塗布した後、第２のガラス基板２２０の加熱強化処理時に焼成させることにより、形成しても良い。ステッカーは、例えば、絵柄が外側（第２のガラス基板２２０側）となるようにして、第２のガラス基板２２０の第３の表面２２２に貼付されても良い。 The printing film may be disposed on the third surface 222 of the second glass substrate 220 by, for example, a screen printing method or an ink jet printing method. The printed film by ceramic firing is, for example, applying a slurry to the third surface 222 of the second glass substrate 220 by screen printing of a glass frit containing a pigment or a dye, and then heating and strengthening the second glass substrate 220. You may form by baking at the time of a process. For example, the sticker may be attached to the third surface 222 of the second glass substrate 220 so that the pattern is on the outside (the second glass substrate 220 side).
　なお、可能な場合、不透明部材２７５は、表示装置２７０の背面（第２のガラス基板２２０側）に、直接設置しても良い。 If possible, the opaque member 275 may be installed directly on the back surface of the display device 270 (on the second glass substrate 220 side).
　（スペーサ材２５０）
　スペーサ材２５０としては、従来の複層ガラスにおいて使用されているものを適用することができる。例えば、スペーサ材２５０は、アルミニウムまたはアルミニウム合金製であっても良い。また、乾燥剤を混練した樹脂製スペーサを用いることもできる。 (Spacer material 250)
As the spacer material 250, the material used in the conventional multilayer glass can be applied. For example, the spacer material 250 may be made of aluminum or an aluminum alloy. A resin spacer in which a desiccant is kneaded can also be used.
　スペーサ材２５０は、内部を中空にして、例えば、シリカゲルのような乾燥剤を内部に設置しても良い。これにより、外界から空間部２３０への水分の侵入を、よりいっそう抑制することができる。 The spacer material 250 may be hollow and a desiccant such as silica gel may be installed inside. Thereby, the penetration | invasion of the water | moisture content from the outside to the space part 230 can be suppressed further.
　（車両用表示機器の製造方法）
　次に、図５～図７を参照して、本発明の一実施例による車両用表示機器の製造方法の一例について、簡単に説明する。 (Method for manufacturing display device for vehicle)
Next, an example of a method for manufacturing a display device for a vehicle according to an embodiment of the present invention will be briefly described with reference to FIGS.

However, it will be apparent to those skilled in the art that the manufacturing method described below can be applied to the first vehicle display device 100 and the third vehicle display device 400 in the same manner. Moreover, in the following description, in order to clarify the description, the reference numerals shown in FIG.

　以下、各工程について説明する。 Hereinafter, each process will be described.
　（ステップＳ１１０）
　まず、第１および第２の表面２１２、２１４を有する第１のガラス基板２１０、ならびに第３および第４の表面２２２、２２４を有する第２のガラス基板２２０が準備される。なお、第２のガラス基板２２０の第３の表面２２２には、機能膜を配置しても良い。 (Step S110)
First, a first glass substrate 210 having first and second surfaces 212, 214 and a second glass substrate 220 having third and fourth surfaces 222, 224 are prepared. Note that a functional film may be disposed on the third surface 222 of the second glass substrate 220.
　次に、図６に示すように、第１のガラス基板２１０の第１の表面２１２の所望の位置に、少なくとも一つの表示装置２７０が配置される。また、第２のガラス基板２２０の第３の表面２２２の所定の位置に、不透明部材２７５が設置される。ただし、不透明部材２７５の設置は、任意である。 Next, as shown in FIG. 6, at least one display device 270 is disposed at a desired position on the first surface 212 of the first glass substrate 210. Further, an opaque member 275 is installed at a predetermined position on the third surface 222 of the second glass substrate 220. However, the installation of the opaque member 275 is arbitrary.
　（ステップＳ１２０）
　次に、第１のガラス基板２１０の第１の表面２１２と、第２のガラス基板２２０の第３の表面２２２とが対向するようにして、両ガラス基板２１０、２２０が積層される。ここで、第１のガラス基板２１０と第２のガラス基板２２０は、両者の間に、表示装置２７０を収容することが可能な空間が形成されるようにして、相互に積層される。 (Step S120)
Next, the glass substrates 210 and 220 are laminated so that the first surface 212 of the first glass substrate 210 and the third surface 222 of the second glass substrate 220 face each other. Here, the first glass substrate 210 and the second glass substrate 220 are stacked on each other so that a space capable of accommodating the display device 270 is formed therebetween.
　図７には、第１のガラス基板２１０と第２のガラス基板２２０の間にそのような空間が形成されるようにして、両ガラス基板２１０、２２０を積層する工程の一例を示す。 FIG. 7 shows an example of a process of laminating both glass substrates 210 and 220 so that such a space is formed between the first glass substrate 210 and the second glass substrate 220.
　図７に示すように、第１のガラス基板２１０の周囲には、略角柱状の４つのスペーサ材２５０ａ～２５０ｄが配置される。これらのスペーサ材２５０ａ～２５０ｄの高さ（図のＺ方向の長さ）は、表示装置２７０の高さよりも大きいことに留意する必要がある。 As shown in FIG. 7, around the first glass substrate 210, four substantially prismatic spacer members 250a to 250d are arranged. It should be noted that the height of the spacer members 250a to 250d (the length in the Z direction in the figure) is larger than the height of the display device 270.
　各スペーサ部材は、内部が中空になっており、この中に、シリカゲル等の乾燥剤を添加しても良い。 Each spacer member has a hollow inside, and a desiccant such as silica gel may be added therein.
　このようなスペーサ材２５０ａ～２５０ｄを用いることにより、両ガラス基板２１０、２２０を積層した際に、両者の間に、密閉空間を形成することができる。また、この密閉空間内に、表示装置２７０を収容することができる。 By using such spacer materials 250a to 250d, when the glass substrates 210 and 220 are laminated, a sealed space can be formed between them. Further, the display device 270 can be accommodated in the sealed space.
　なお、このようなスペーサ材２５０ａ～２５０と、第１および第２のガラス基板２１０、２２０との接合方法としては、従来の複層ガラスの製造方法に利用される技術を適用することができるため、ここではこれ以上説明しない。 As a method for joining the spacer members 250a to 250 and the first and second glass substrates 210 and 220, a technique used in a conventional method for producing a multilayer glass can be applied. No further explanation here.
　以上の工程により、第２の車両用表示機器２００を製造することができる。 Through the above steps, the second vehicle display device 200 can be manufactured.
　本発明は、例えば、鉄道車両の窓、飛行機の窓、自動車のウィンドウ、および建物の窓ガラス等に適用することができる。 The present invention can be applied to, for example, railway vehicle windows, airplane windows, automobile windows, and window glass of buildings.
