　本発明は、偽造防止効果や装飾効果を有する表示体及び情報印刷物に関する。 The present invention relates to a display body and an information printed matter having an anti-counterfeit effect and a decorative effect.
　従来、文字又は図柄が表示された情報印刷物の主面の一部や、情報印刷物に貼付される表示体にマイクロ文字、特殊発光インキ、すかし、ホログラム、回折格子等の視覚効果を持たせる技術が知られている。 Conventionally, a technology that gives visual effects such as micro characters, special luminescent inks, watermarks, holograms, diffraction gratings, etc. to a part of the main surface of information printed matter on which characters or designs are displayed, or a display attached to the information printed matter It has been known.
　ホログラムや回析格子を用いる技術は容易に模倣できないため、従来から偽造防止手段に用いられている。例えば、偽造防止手段として、有価証券類、クレジットカード、パスポート、免許証、身分証、紙幣に貼付される表示体に情報をホログラムや回析格子により表示して偽造防止効果を持たせる技術が知られている（例えば、日本国特許公開公報　特開２００３－２９５７４４号）。 Since technology using holograms and diffraction gratings cannot be easily imitated, it has been used for counterfeiting. For example, as a means for preventing counterfeiting, there is known a technology for preventing forgery by displaying information on a display attached to securities, credit cards, passports, licenses, identification cards, and banknotes using a hologram or diffraction grating. (For example, Japanese Patent Publication No. 2003-295744).

For example, it is good also as a structure which selected and combined 2 or more types from the material shown above.
　非成形部４２は、膜状に形成された基材のうち、成形部４３以外の部位である。即ち、基材の成形されていない部位である。 The non-molded part 42 is a part other than the molded part 43 in the base material formed in a film shape. That is, it is an unmolded portion of the base material.
　成形部４３は、長手方向が一方向に延設される傾斜面７１を有する複数の突起部５１を備える。成形部４３は、膜状の基材の一方の主面の一部に上述の加工によって複数の溝７３を形成することにより、傾斜面７１を有する複数の突起部５１が構成される。成形部４３は、表示したい情報Ｔの形状に複数の突起部５１が配置される。図１に示すように、例えば、本実施形態において、成形部４３は、Ｔ字形状に複数の突起部５１が配置されることで表示する情報Ｔの形状を構成する。成形部４３は、図４に示すように、溝７３を構成する複数の突起部５１により鋸波形状の断面を有する。 The forming part 43 includes a plurality of protrusions 51 having an inclined surface 71 whose longitudinal direction extends in one direction. The forming portion 43 is formed with a plurality of protrusions 51 having inclined surfaces 71 by forming a plurality of grooves 73 on a part of one main surface of the film-like base material by the above-described processing. In the molding unit 43, a plurality of protrusions 51 are arranged in the shape of the information T desired to be displayed. As shown in FIG. 1, for example, in the present embodiment, the molding unit 43 configures the shape of information T to be displayed by arranging a plurality of protrusions 51 in a T shape. As shown in FIG. 4, the molding portion 43 has a sawtooth cross section due to the plurality of protrusions 51 constituting the groove 73.
　突起部５１は、軸方向が非成形部４２の主面に沿った姿勢で、一方向に延びる三角柱状に形成される。基材を厚み方向の途中まで溝７３を加工することにより形成される突起部５１は、当該基材の厚み方向の途中から加工されていない非成形部４２と連続して一体に設けられる。突起部５１は、非成形部４２に一体に設けられることで、軸方向に沿った二つの外面を有する。突起部５１は、三角柱状の軸方向に沿った、２つの外面の一が傾斜面７１により構成される。また、突起部５１は、当該２つの外面の他が軸方向及び非成形部４２の主面に直交する方向に沿った垂直面７２により構成される。換言すると、突起部５１は、成形層２１へ入射する光Ｌ１の入射方向に対して傾斜する傾斜面７１と、当該光Ｌ１の入射方向に沿った垂直面７２と、により外面が構成される。また、突起部５１は、軸方向と直交する方向に並列に複数配置される。 The projection 51 is formed in a triangular prism shape extending in one direction with the axial direction being along the main surface of the non-molded portion 42. The protrusion 51 formed by processing the groove 73 in the middle of the thickness direction of the base material is provided continuously and integrally with the non-molded portion 42 that is not processed from the middle of the thickness direction of the base material. The protruding portion 51 is provided integrally with the non-molded portion 42 and thus has two outer surfaces along the axial direction. The protrusion 51 is configured by an inclined surface 71 on one of two outer surfaces along the axial direction of the triangular prism. Further, the protrusion 51 is constituted by a vertical surface 72 along the direction perpendicular to the main surface of the non-molded portion 42 in addition to the two outer surfaces. In other words, the protrusion 51 has an outer surface constituted by the inclined surface 71 inclined with respect to the incident direction of the light L1 incident on the molding layer 21 and the vertical surface 72 along the incident direction of the light L1. A plurality of the protrusions 51 are arranged in parallel in a direction orthogonal to the axial direction.
　これらのように、成形部４３は、複数の突起部５１を有することで、隣り合う突起部５１の一方の突起部５１の傾斜面７１と他方の突起部５１の垂直面７２とにより構成される溝７３を複数有する。即ち、成形部４３は、隣り合う突起部５１の間に構成された溝７３により、傾斜面７１に向かう光の入射路及び傾斜面からの光の出射路を構成する。 As described above, the molding unit 43 includes the plurality of projections 51, and thus includes the inclined surface 71 of one projection 51 of the adjacent projection 51 and the vertical surface 72 of the other projection 51. A plurality of grooves 73 are provided. In other words, the molding unit 43 forms a light incident path toward the inclined surface 71 and a light emission path from the inclined surface by the groove 73 formed between the adjacent protrusions 51.
　本実施形態における、成形部４３の一例を図１及び図２の部分Ｐを用いて説明する。ここで、部分Ｐは、情報Ｔを構成する成形部４３の所定の領域である。なお、情報Ｔは、例えば、視覚効果の違いにより区分けされる複数の画素Ｕの集合により構成される。例えば、画素Ｕは、異なる傾斜面７１の傾斜角度又は異なる溝７３の幅に構成される。 An example of the molding part 43 in the present embodiment will be described with reference to a part P in FIGS. Here, the portion P is a predetermined region of the forming portion 43 constituting the information T. Note that the information T is composed of, for example, a set of a plurality of pixels U that are classified according to differences in visual effects. For example, the pixels U are configured to have different inclination angles of the inclined surfaces 71 or different widths of the grooves 73.
　例えば、図３及び図４に示すように、部分Ｐにおける成形部４３は、傾斜角度及び傾斜方向が異なり、同一の高さを有する複数の突起部５１を備えている。換言すると、部分Ｐにおける成形部４３は、深さが同じであって、突起部５１の軸方向で見た形状が異なる複数の溝７３を有する。 For example, as shown in FIGS. 3 and 4, the molding portion 43 in the portion P includes a plurality of protrusions 51 having different inclination angles and inclination directions and having the same height. In other words, the forming portion 43 in the portion P has a plurality of grooves 73 having the same depth and different shapes as viewed in the axial direction of the protruding portion 51.
　具体的には、成形部４３は、複数の第１突起部５１Ａを有する第１領域１０１、複数の第２突起部５１Ｂを有する第２領域１０２、複数の第３突起部５１Ｃを有する第３領域１０３、複数の第４突起部５１Ｄを有する第４領域１０４を構成する。 Specifically, the molding unit 43 includes a first region 101 having a plurality of first protrusions 51A, a second region 102 having a plurality of second protrusions 51B, and a third region having a plurality of third protrusions 51C. 103, and constitutes a fourth region 104 having a plurality of fourth protrusions 51D.
　即ち、成形部４３は、隣り合う第１突起部５１Ａの間に設けられた複数の第１溝７３Ａと、隣り合う第２突起部５１Ｂの間に設けられた複数の第２溝７３Ｂと、隣り合う第３突起部５１Ｃの間に設けられた複数の第３溝７３Ｃと、隣り合う第４突起部５１Ｄの間に設けられた複数の第４溝７３Ｄと、を構成する。 That is, the molding portion 43 is adjacent to the plurality of first grooves 73A provided between the adjacent first protrusion portions 51A and the plurality of second grooves 73B provided between the adjacent second protrusion portions 51B. A plurality of third grooves 73C provided between the matching third protrusions 51C and a plurality of fourth grooves 73D provided between the adjacent fourth protrusions 51D are configured.
　なお、これら第１領域１０１、第２領域１０２、第３領域１０３及び第４領域１０４は、複数の突起部５１が配置される方向に順次配置される。 The first region 101, the second region 102, the third region 103, and the fourth region 104 are sequentially arranged in the direction in which the plurality of protrusions 51 are arranged.
　これら第１領域１０１、第２領域１０２、第３領域１０３及び第４領域１０４は、突起部５１の傾斜角度及び傾斜方向により区分された領域である。 The first area 101, the second area 102, the third area 103, and the fourth area 104 are areas divided by the inclination angle and the inclination direction of the protrusion 51.
　第１突起部５１Ａは、第１傾斜面７１Ａを有する。第２突起部５１Ｂは、第１傾斜面７１Ａと傾斜方向が同じであって、且つ、傾斜角度が異なる第２傾斜面７１Ｂを有する。 The first protrusion 51A has a first inclined surface 71A. The second protrusion 51B has a second inclined surface 71B having the same inclination direction as the first inclined surface 71A and having a different inclination angle.
　第３突起部５１Ｃは、第２傾斜面７１Ｂと傾斜方向が異なり、且つ、傾斜角度が同じ第３傾斜面７１Ｃを有する。第４突起部５１Ｄは、第３傾斜面７１Ｃと傾斜方向が同じであって、且つ、傾斜角度が異なる第４傾斜面７１Ｄを有する。ここで、第１突起部５１Ａ及び第２突起部５１Ｂと第３突起部５１Ｃ及び第４突起部５１Ｄとの傾斜方向は、光の入射方向に沿って第２突起部５１Ｂ及び第３突起部５１Ｃの領域を通過する線を中心軸とした場合における当該中心軸に線対称に構成される。なお、同じ傾斜角度で傾斜方向が異なる傾斜面とは、換言すると、一方の傾斜面７１が他方の傾斜面７１と対称形状となるように、一方の傾斜角度に対して他方の傾斜面の傾斜角度が異なることである。 The third protrusion 51C has a third inclined surface 71C that is different in inclination direction from the second inclined surface 71B and has the same inclination angle. The fourth protrusion 51D has a fourth inclined surface 71D having the same inclination direction as the third inclined surface 71C and having a different inclination angle. Here, the inclination directions of the first protrusion 51A and the second protrusion 51B and the third protrusion 51C and the fourth protrusion 51D are the second protrusion 51B and the third protrusion 51C along the light incident direction. When the line passing through the region is the central axis, the line is symmetrical with respect to the central axis. It should be noted that an inclined surface having the same inclination angle and a different inclination direction is, in other words, an inclination of the other inclined surface with respect to one inclination angle so that one inclined surface 71 is symmetrical with the other inclined surface 71. The angle is different.
　例えば、第１溝７３Ａの幅、換言すると隣り合う第１突起部５１Ａの頂部間の距離は、２０μｍに構成される。第２溝７３Ｂの幅は、３０μｍに構成される。第３溝７３Ｃの幅は、第２溝７３Ｂの幅と同じ３０μｍに構成される。第４溝７３Ｄの幅は、第１溝７３Ａの幅と同じ２０μｍに構成される。なお、これら溝７３の幅は、求められる視覚効果によって適宜設定される。例えば、溝７３の幅は、視認される画像の色に影響を及ぼし、例えば、溝７３の幅を３μｍ程度に構成することで回折光が射出されることから、反射する光により視認される情報Ｔの色彩に虹色の光が求められる場合には、当該幅に溝７３が設定される。また、虹色の光が所望されない場合には、溝７３の幅を長くすると回析光が生じないことから、溝７３の幅を３μｍより大きく設定すればよい。なお、成形部４３においては、虹色の光を求めない例として、上記幅が設定されている。このように、溝７３の間の長さは、所望される視覚効果に応じて適宜設定及び調整される。 For example, the width of the first groove 73A, in other words, the distance between the tops of the adjacent first protrusions 51A is configured to be 20 μm. The width of the second groove 73B is 30 μm. The width of the third groove 73C is configured to be 30 μm, which is the same as the width of the second groove 73B. The width of the fourth groove 73D is configured to be 20 μm, which is the same as the width of the first groove 73A. The widths of the grooves 73 are appropriately set depending on the required visual effect. For example, the width of the groove 73 affects the color of the visually recognized image. For example, since the diffracted light is emitted by configuring the width of the groove 73 to be about 3 μm, the information visually recognized by the reflected light. When rainbow light is required for the T color, the groove 73 is set to the width. Further, when rainbow light is not desired, diffraction light does not occur when the width of the groove 73 is increased. Therefore, the width of the groove 73 may be set to be larger than 3 μm. In the molding part 43, the above width is set as an example in which rainbow light is not obtained. Thus, the length between the grooves 73 is appropriately set and adjusted according to the desired visual effect.
　反射層２２は、傾斜面７１に入射した光を反射するために、成形層２１の材料よりも反射率の高い材料により構成される。反射層２２は、図４に示すように、傾斜面７１の全体に設けられる。反射層２２の材料は、所定の反射率を有していれば、透明又は不透明の材料のどちらの材料を用いることもできる。本実施形態において、反射層２２は、不透明の材料により構成される。ここで、不透明な反射材の材料とは、可視光に対して透過率が５％以下の材料を用いることができる。材料としては、例えば、アルミニウム、銀、錫、クロム、ニッケル、銅、金、及びこれらの合金を含む金属材料である。 The reflective layer 22 is made of a material having a higher reflectance than the material of the molding layer 21 in order to reflect light incident on the inclined surface 71. As shown in FIG. 4, the reflective layer 22 is provided on the entire inclined surface 71. The material of the reflective layer 22 can be either transparent or opaque material as long as it has a predetermined reflectance. In the present embodiment, the reflective layer 22 is made of an opaque material. Here, as the material of the opaque reflecting material, a material having a transmittance of 5% or less with respect to visible light can be used. Examples of the material include metal materials including aluminum, silver, tin, chromium, nickel, copper, gold, and alloys thereof.
　反射層２２は、例えば、真空蒸着法、スパッタリング法等の金属又は酸化チタンや硫化亜鉛等の酸化物を用いた真空製膜法により形成することができる。 The reflective layer 22 can be formed, for example, by a vacuum film forming method using a metal such as a vacuum deposition method or a sputtering method, or an oxide such as titanium oxide or zinc sulfide.
　被覆層２３は、空気よりも大きな屈折率を有することで、溝７３に入射された光の光路長を被覆層２３が設けられていない場合に同光路上に入射された光の光路長と異ならせることが可能に構成される。ここで、溝７３における光路長とは、被覆層２３の屈折率ｎに溝７３の深さＨ１を乗じたものである。 Since the covering layer 23 has a refractive index larger than that of air, the optical path length of the light incident on the groove 73 is different from the optical path length of the light incident on the optical path when the covering layer 23 is not provided. Can be configured. Here, the optical path length in the groove 73 is obtained by multiplying the refractive index n of the coating layer 23 by the depth H1 of the groove 73.
　被覆層２３は、一種類の高屈折率を有する材料からなる単層構造、又は複数の異なる高屈折率を有する材料を重ねて配置した多層構造により構成される。ここで、高屈折率を有する材料とは、屈折率が１．６以上の材料である。 The covering layer 23 has a single layer structure made of a material having one kind of high refractive index, or a multilayer structure in which a plurality of materials having different high refractive indices are stacked. Here, the material having a high refractive index is a material having a refractive index of 1.6 or more.
　また、被覆層２３は、成形層２１及び反射層２２を覆う透明または半透明の層であって、成形層２１及び反射層２２と接していない側の主面が平面に構成される層である。 The covering layer 23 is a transparent or translucent layer that covers the molding layer 21 and the reflective layer 22, and is a layer in which the main surface on the side that is not in contact with the molding layer 21 and the reflective layer 22 is a flat surface. .
　ここで、被覆層２３における透明とは可視光に対して９５％以上透過することであり、また、半透明とは、可視光に対して７０％以上透過することである。例えば、被覆層２３は、チオウレタン系の樹脂材料を用いることができる。被覆層２３は、例えば、単層構造により構成される。 Here, the transparency in the covering layer 23 means that 95% or more of visible light is transmitted, and the semi-transparent means that 70% or more of visible light is transmitted. For example, the coating layer 23 can use a thiourethane resin material. The covering layer 23 has a single layer structure, for example.
　被覆層２３は、例えば、凹版印刷等の印刷技術を用いて成形層２１及び反射層２２を覆うように膜状に形成される。 The covering layer 23 is formed in a film shape so as to cover the molding layer 21 and the reflective layer 22 using a printing technique such as intaglio printing.
　接着層２４は、非成形部４２の他方の主面に設けられ、表示体１２をカード部１１に接着するための材料により構成される。接着層２４は、カード部１１に表示体１２を貼付することができれば、単層構造又は多層構造とすることも可能である。即ち、接着層２４は、表示体１２及びカード部１１の材料や接着表面の平滑性等を考慮して適宜設定される。例えば、接着層２４は、単層構造に構成される。 The adhesive layer 24 is provided on the other main surface of the non-molded part 42 and is made of a material for adhering the display body 12 to the card part 11. If the display body 12 can be stuck to the card | curd part 11, the contact bonding layer 24 can also be made into a single layer structure or a multilayer structure. That is, the adhesive layer 24 is appropriately set in consideration of the material of the display body 12 and the card unit 11 and the smoothness of the adhesive surface. For example, the adhesive layer 24 has a single layer structure.
　次に、本実施形態に係る表示体１２の光の反射挙動について図４及び図５を用いて説明する。なお、図４及び図５において、観察者が表示体１２を被覆層２３側の主面を正面視した状態における光の反射挙動について説明する。また、以下の説明においては、反射層２２に入射する光のうち表示体１２の主面に対して垂直に入射する光の一部のみを用いて説明する。 Next, the light reflection behavior of the display body 12 according to the present embodiment will be described with reference to FIGS. 4 and 5, the light reflection behavior in a state where the observer views the display body 12 from the front surface of the covering layer 23 side will be described. Further, in the following description, only a part of the light incident on the reflective layer 22 that is perpendicular to the main surface of the display body 12 will be described.
　図４に示すように、光Ｌ１は、被覆層２３を透過し、成形部４３の溝７３を通り反射層２２に入射される。ここで、成形層２１及び反射層２２は被覆層２３で覆われていることから、反射層２２で反射された光Ｌ２は、被覆層２３で覆われていないときに反射される光Ｌ３と異なる方向に反射される。 As shown in FIG. 4, the light L <b> 1 passes through the coating layer 23, passes through the groove 73 of the molding portion 43, and enters the reflective layer 22. Here, since the molding layer 21 and the reflective layer 22 are covered with the covering layer 23, the light L2 reflected by the reflective layer 22 is different from the light L3 reflected when not covered by the covering layer 23. Reflected in the direction.
　具体的には、溝７３の屈折率が１である場合、即ち、空気が溝７３に存在する場合又は空気と同程度の屈折率の材料で溝７３が被覆されている場合には、反射層２２で反射する光Ｌ３は、２点鎖線で示す方向に向かって反射する。 Specifically, when the refractive index of the groove 73 is 1, that is, when air is present in the groove 73 or when the groove 73 is covered with a material having a refractive index similar to that of air, the reflective layer The light L3 reflected at 22 is reflected in the direction indicated by the two-dot chain line.
　これに対して、被覆層２３が溝７３に設けられている場合には、反射層２２で反射する光Ｌ２は、反射方向が変化する。このように、被覆層２３により反射層２２で反射した光Ｌ２の反射方向は、屈折率が１である場合における傾斜面７１の傾斜角度と異なる傾斜面７４で反射した反射方向と同じとなる。 On the other hand, when the coating layer 23 is provided in the groove 73, the reflection direction of the light L2 reflected by the reflection layer 22 changes. Thus, the reflection direction of the light L2 reflected by the reflection layer 22 by the coating layer 23 is the same as the reflection direction reflected by the inclined surface 74 different from the inclination angle of the inclined surface 71 when the refractive index is 1.
　即ち、溝７３は、高屈折材料である被覆層２３の特性により、溝７３の幅は同じであり、且つ、溝７３の深さが疑似的に深くなる。換言すると、被覆層２３の特性により、傾斜面７１を有する突起部５１の形状が、突起部５１と幅が同じで、且つ、高さが突起部５１よりもＨ２だけ高い疑似突起部５２が成形部４３に設けられていることに疑似的になる。 That is, the groove 73 has the same width as the groove 73 and the depth of the groove 73 becomes pseudo deep due to the characteristics of the coating layer 23 that is a highly refractive material. In other words, due to the characteristics of the coating layer 23, the shape of the projection 51 having the inclined surface 71 is the same as the projection 51, and the pseudo projection 52 is higher in height than the projection 51 by H 2. It becomes pseudo that it is provided in the part 43.
　これにより、傾斜面７１と垂直面７２とがなす角度をθ１とし、被覆層２３の特性により疑似的に表される傾斜面７４と垂直面７２とがなす角度をθ２が異なることから、反射層２２で反射する光Ｌ２の反射方向を異ならせることが可能となる。これにより、観察者が視認した溝７３の深さは、疑似的に深く視認される。例えば、屈折率が１．６の高屈折材料で埋められた深さ５μｍの溝は、疑似的に深さ８μｍの深さの溝として認識される。 As a result, the angle formed between the inclined surface 71 and the vertical surface 72 is θ1, and the angle formed between the inclined surface 74 and the vertical surface 72 that is artificially represented by the characteristics of the coating layer 23 is different from θ2. The reflection direction of the light L <b> 2 reflected at 22 can be made different. Thereby, the depth of the groove 73 visually recognized by the observer is visually perceived deeply. For example, a groove having a depth of 5 μm and filled with a high refractive material having a refractive index of 1.6 is recognized as a groove having a depth of 8 μm in a pseudo manner.
　この結果、実際の傾斜面７１で反射した光Ｌ３の反射方向によって観察者が視認する成形部４３の立体的な形状に比べ、表示体１２の成形部４３の立体的な形状は、さらに高さのある立体として視認される。 As a result, the three-dimensional shape of the molding portion 43 of the display body 12 is higher than the three-dimensional shape of the molding portion 43 visually recognized by the observer according to the reflection direction of the light L3 reflected by the actual inclined surface 71. It is visually recognized as a three-dimensional solid.
　また成形部４３を用いた表示体１２は、例えば、部分Ｐにおいて、第１傾斜面７１Ａ、第２傾斜面７１Ｂ、第３傾斜面７１Ｃ、または、第４傾斜面７１Ｄをそれぞれ、傾斜角度又は傾斜方向を異ならせることで、第２傾斜面７１Ｂ及び第３傾斜面７１Ｃにおいて最も高くなるような立体的な形状を表すことができる。 Moreover, the display body 12 using the shaping | molding part 43, for example, in the part P, makes 1st inclined surface 71A, 2nd inclined surface 71B, 3rd inclined surface 71C, or 4th inclined surface 71D, respectively. By making the directions different, it is possible to represent a three-dimensional shape that is highest in the second inclined surface 71B and the third inclined surface 71C.
　これにより、表示体１２は、成形層２１の成形部４３に形成された複数の傾斜面７１により視認される立体的に表現される画像について被覆層２３を設けていない場合よりも、さらに立体的に表現することができる。 Thereby, the display body 12 is further three-dimensional than the case where the coating layer 23 is not provided about the image represented in three dimensions visually recognized by the some inclined surface 71 formed in the shaping | molding part 43 of the shaping | molding layer 21. FIG. Can be expressed in
　このように構成された情報印刷物１によれば、表示体１２の被覆層２３に高屈折材料を用い、成形層２１を覆う構成であることから、光の反射方向を制御することで立体的な視覚効果を得る場合に、実際の溝７３よりも深い溝７３で反射したときに生じる視覚効果を得ることができる。 According to the information printed matter 1 configured as described above, since the high refractive material is used for the covering layer 23 of the display body 12 and the molding layer 21 is covered, the three-dimensional structure can be obtained by controlling the light reflection direction. In the case of obtaining a visual effect, it is possible to obtain a visual effect that occurs when reflected by a groove 73 deeper than the actual groove 73.
　また、このような情報印刷物１に用いられる表示体１２は、被覆層２３により成形層２１及び反射層２２が覆われることから、傾斜面７１の傾斜角度を知ることが困難である。よって、第三者が成形部４３を偽造することが困難となる。また、上述したように立体的に表示される効果が向上することから、デザイン性が向上するとともに、偽造品との見分けが容易となる。これらのように、情報印刷物１に用いられる表示体１２は、アイキャッチ効果を生じると共に、高い偽造防止効果を備え、容易に肉眼により偽造の真偽判定が可能となる。 Further, in the display body 12 used for such information printed matter 1, it is difficult to know the inclination angle of the inclined surface 71 because the molding layer 21 and the reflective layer 22 are covered with the covering layer 23. Therefore, it becomes difficult for a third party to forge the molding part 43. Moreover, since the effect displayed in three dimensions improves as mentioned above, while improving design property, it becomes easy to distinguish from a forgery product. As described above, the display body 12 used in the printed information product 1 has an eye catching effect and a high forgery prevention effect, and can easily determine whether the forgery is forgery with the naked eye.
　また、表示体１２は、成形層２１及び反射層２２を被覆層２３で覆う構成により、成形層２１及び反射層２２を汚れや傷から保護することができ、長期間に亘って特別な視覚効果を維持できる。即ち、表示体１２は、流通過程における成形層２１の損傷を防止し、寿命を向上することができる。 In addition, the display body 12 can protect the molding layer 21 and the reflection layer 22 from dirt and scratches by covering the molding layer 21 and the reflection layer 22 with the coating layer 23, and has a special visual effect over a long period of time. Can be maintained. That is, the display body 12 can prevent the molding layer 21 from being damaged in the distribution process and can improve the life.
　上述したように本発明の第１の実施形態に係る表示体１２を用いた情報印刷物１は、高い視覚効果を有し、偽造の防止、偽造の真偽判定の容易化、寿命の向上、及び、デザイン性の向上が可能となる。 As described above, the information printed matter 1 using the display body 12 according to the first embodiment of the present invention has a high visual effect, prevents forgery, facilitates determination of forgery / falseness, improves life, and It becomes possible to improve the design.
　（第２の実施形態）
　以下、本発明に係る第２の実施形態について図６及び図７を用いて説明する。　
　図６は、第２の実施形態に係る情報印刷物１に用いられる表示体１２Ａの構成を示す平面図であり、図７は、表示体１２Ａの構成を示す断面図である。なお、第２の実施形態に係る表示体１２Ａの構成のうち、第１の実施形態に係る表示体１２と同様の構成には、同一符号を付し、その詳細な説明は省略する。 (Second Embodiment)
Hereinafter, a second embodiment according to the present invention will be described with reference to FIGS.
FIG. 6 is a plan view showing the configuration of the display body 12A used in the information printed matter 1 according to the second embodiment, and FIG. 7 is a cross-sectional view showing the configuration of the display body 12A. Note that, in the configuration of the display body 12A according to the second embodiment, the same reference numerals are given to the same configurations as those of the display body 12 according to the first embodiment, and detailed description thereof is omitted.
　図６及び図７に示すように表示体１２Ａは、情報印刷物１のカード部１１上に貼付される。　
　図７に示すように、表示体１２Ａは、成形層２１Ａと、成形層２１Ａの一方の主面に構成される反射層２２と、成形層２１Ａ及び反射層２２を覆う被覆層２３と、成形層２１Ａの他方の主面に設けられる接着層２４とを有する。 As shown in FIGS. 6 and 7, the display body 12 </ b> A is pasted on the card portion 11 of the information printed matter 1.
As shown in FIG. 7, the display body 12A includes a molding layer 21A, a reflective layer 22 formed on one main surface of the molding layer 21A, a coating layer 23 covering the molding layer 21A and the reflection layer 22, and a molding layer. And an adhesive layer 24 provided on the other main surface of 21A.
　成形層２１Ａは、カード部１１の主面３１に接着層２４を介して接着される。　
　成形層２１Ａは、主面が平坦な膜状に形成された樹脂材料からなる基材の一方の主面を切削加工又はレーザー描画機を用いた加工により成形部４３を成形することで、成形部４３Ａが構成される。成形層２１Ａは、上述した成形層２１と同様の材料により構成される。 The molding layer 21 </ b> A is bonded to the main surface 31 of the card unit 11 via the adhesive layer 24.
The molding layer 21A is formed by molding the molding part 43 by molding one principal surface of a base material made of a resin material having a principal surface formed into a flat film by machining or processing using a laser drawing machine. 43A is configured. The molding layer 21A is made of the same material as the molding layer 21 described above.
　成形部４３Ａは、その表面に、光の入射方向に対して接線が傾斜する所定の曲率を有する複数の曲面８１Ａを有する。例えば、成形部４３Ａは、膜状の基材の一方の主面の一部に上述の加工によって複数の同心円状の溝８３を形成することにより、曲面８１Ａを有する複数の突起部６１が構成される。図６に示すように、例えば、本実施形態において、成形部４３Ａは、径が異なり、且つ、同一の曲率半径の外面を有する円環状の突起部６１が複数配置されることで構成される。 The molding portion 43A has a plurality of curved surfaces 81A having a predetermined curvature with tangents inclined with respect to the light incident direction on the surface thereof. For example, in the molding portion 43A, a plurality of concentric grooves 83 are formed on a part of one main surface of the film-like base material by the above-described processing, thereby forming a plurality of protrusions 61 having a curved surface 81A. The As shown in FIG. 6, for example, in the present embodiment, the molding portion 43 </ b> A is configured by arranging a plurality of annular projections 61 having different diameters and having outer surfaces with the same curvature radius.
　より具体的に説明すると、突起部６１は、成形層２１へ入射する光Ｌ４の入射方向に対して所定の曲率で傾斜する曲面８１Ａと、光の入射方向に沿った垂直面８２により外面が構成される。このような成形部４３Ａは、いわゆるフレネルレンズ形状を呈している。 More specifically, the protrusion 61 has an outer surface constituted by a curved surface 81A inclined at a predetermined curvature with respect to the incident direction of the light L4 incident on the molding layer 21 and a vertical surface 82 along the incident direction of the light. Is done. Such a molded part 43A has a so-called Fresnel lens shape.
　複数の突起部６１の曲面８１Ａは、曲率Ｒ１が同一に構成されていてもよく、異なる曲率Ｒ１としてもよい。反射層２２は、成形層２１Ａの曲面８１Ａの全面に設けられる。被覆層２３は、成形層２１Ａ及び反射層２２上に設けられ、その主面が光の入射方向に対して直交する方向に延設する主面を有する。 The curved surfaces 81A of the plurality of protrusions 61 may have the same curvature R1, or may have different curvatures R1. The reflective layer 22 is provided on the entire surface of the curved surface 81A of the molding layer 21A. The covering layer 23 is provided on the molding layer 21 </ b> A and the reflective layer 22, and has a main surface extending in a direction orthogonal to the light incident direction.
　このように構成された表示体１２Ａは、上述した表示体１２と同様に、被覆層２３によって、入射した光を曲面８１Ａに設けられた反射層２２で反射した光の出射方向と異なる出射方向とすることが可能となる。 12 A of display bodies comprised in this way are different from the output direction of the light which reflected the incident light with the reflection layer 22 provided in the curved surface 81A by the coating layer 23 similarly to the display body 12 mentioned above. It becomes possible to do.
　具体的に説明すると、表示体１２Ａは、入射した光が曲面８１Ａの反射層２２で反射されるとき、当該光Ｌ４は、当該曲面８１Ａの接線に対して反射する。このとき、光Ｌ４は、被覆層２３により屈折することから、図７に二点鎖線で示す曲面８１Ａ２に設けられた反射層２２で反射された反射方向と同一の方向に反射する。 Specifically, the display body 12A reflects the light L4 with respect to the tangent to the curved surface 81A when the incident light is reflected by the reflective layer 22 of the curved surface 81A. At this time, since the light L4 is refracted by the coating layer 23, the light L4 is reflected in the same direction as the reflection direction reflected by the reflection layer 22 provided on the curved surface 81A2 indicated by a two-dot chain line in FIG.
　換言すると、光路長は、屈折率ｎと曲面８１Ａの高さＨの積（ｎ×Ｈ）となることから、成形層２１Ａは、曲率Ｒ２の曲面８１Ａ２を有する形状、即ち、曲面８１Ａの高さがｎ倍となる形状に視認することが可能となる。よって、曲面８１Ａの高さが大きく視認できることから、表示体１２Ａは、立体感を強調することが可能となる。 In other words, since the optical path length is the product (n × H) of the refractive index n and the height H of the curved surface 81A, the molding layer 21A has a shape having the curved surface 81A2 with the curvature R2, that is, the height of the curved surface 81A. Can be visually recognized in a shape of n times. Therefore, since the height of the curved surface 81A can be visually recognized, the display body 12A can enhance the stereoscopic effect.
　このように、表示体１２Ａは、成形層２１Ａに設けられた突起部６１の曲面８１Ａにおける反射強度比の違いによって立体的な球面状に観察される。また、表示体１２Ａは、被覆層２３の屈折率を制御することで、視認される球面状の立体の高さを疑似的に高くすること、及び、当該高さを制御することが可能となる。 Thus, the display body 12A is observed in a three-dimensional spherical shape due to the difference in the reflection intensity ratio on the curved surface 81A of the protrusion 61 provided on the molding layer 21A. In addition, the display body 12A can control the refractive index of the covering layer 23 to artificially increase the height of the spherical solid that is visually recognized, and to control the height. .
　（第３の実施形態）
　以下、本発明に係る第３の実施形態について図８を用いて説明する。　
　図８は、第３の実施形態に係る情報印刷物１に用いられる表示体１２Ｂの構成を示す断面図である。なお、第３の実施形態に係る表示体１２Ｂの構成のうち、第１の実施形態に係る表示体１２及び第２の実施形態に係る表示体１２Ａと同様の構成には、同一符号を付し、その詳細な説明は省略する。 (Third embodiment)
A third embodiment according to the present invention will be described below with reference to FIG.
FIG. 8 is a cross-sectional view illustrating a configuration of a display body 12B used in the information printed matter 1 according to the third embodiment. Note that, in the configuration of the display body 12B according to the third embodiment, the same reference numerals are given to the same configurations as the display body 12 according to the first embodiment and the display body 12A according to the second embodiment. Detailed description thereof will be omitted.
　図８に示すように表示体１２Ｂは、情報印刷物１のカード部１１上に貼付される。　
　図８に示すように、表示体１２Ｂは、成形層２１Ｂと、成形層２１Ｂの一方の主面に構成される反射層２２と、成形層２１Ｂ及び反射層２２を覆う被覆層２３と、成形層２１Ｂの他方の主面に設けられる接着層２４とを有する。 As shown in FIG. 8, the display body 12 </ b> B is stuck on the card unit 11 of the information printed matter 1.
As shown in FIG. 8, the display body 12B includes a molding layer 21B, a reflective layer 22 formed on one main surface of the molding layer 21B, a coating layer 23 covering the molding layer 21B and the reflection layer 22, and a molding layer. And an adhesive layer 24 provided on the other main surface of 21B.
　成形層２１Ｂは、カード部１１の主面３１に接着層２４を介して接着される。　
　成形層２１Ｂは、主面が所定の曲率で湾曲するドーム状に形成された樹脂材料により構成される。即ち、成形層２１Ｂは、その表面に、光の入射方向に対して接線が傾斜する所定の曲率の曲面８１Ｂを有している。成形層２１Ｂは、上述した成形層２１、２１Ａと同様の材料により構成される。 The molding layer 21 </ b> B is bonded to the main surface 31 of the card unit 11 via the adhesive layer 24.
The molding layer 21B is made of a resin material formed in a dome shape whose main surface is curved with a predetermined curvature. That is, the molding layer 21 </ b> B has a curved surface 81 </ b> B having a predetermined curvature whose tangent line is inclined with respect to the light incident direction on the surface thereof. The molding layer 21B is made of the same material as the molding layers 21 and 21A described above.
　曲面８１Ｂは、その外面の接線が光の入射方向に対して傾斜する曲面である。なお、曲面８１Ｂは、その曲率Ｒ１を適宜設定可能である。また、曲面８１Ｂは、異なる複数の曲率を有する曲面であってもよい。 The curved surface 81B is a curved surface whose tangent line on the outer surface is inclined with respect to the incident direction of light. Note that the curvature R1 of the curved surface 81B can be set as appropriate. The curved surface 81B may be a curved surface having a plurality of different curvatures.
　反射層２２は、図８に示すように、成形層２１Ｂの曲面８１Ｂの全面に設けられる。　
　被覆層２３は、成形層２１Ｂ及び反射層２２上に設けられ、その主面が光の入射方向に対して直交する方向に延設する主面を有する。 As shown in FIG. 8, the reflective layer 22 is provided on the entire surface of the curved surface 81B of the molding layer 21B.
The coating layer 23 is provided on the molding layer 21 </ b> B and the reflective layer 22, and has a main surface extending in a direction orthogonal to the light incident direction.
　このように構成された表示体１２Ｂは、上述した表示体１２と同様に、被覆層２３によって、入射した光Ｌ４を曲面８１Ｂに設けられた反射層２２で反射した二点鎖線で示す光の出射方向と異なる、実線で示す出射方向にすることが可能となる。 Similarly to the display body 12 described above, the display body 12B configured as described above emits light indicated by a two-dot chain line in which incident light L4 is reflected by the reflective layer 22 provided on the curved surface 81B by the coating layer 23. It becomes possible to make it the outgoing direction shown by the solid line different from the direction.
　具体的に説明すると、表示体１２Ｂは、入射した光が曲面８１Ｂの反射層２２で反射されるとき、当該光は、当該曲面８１Ｂの接線に対して反射する。このとき、光は、被覆層２３により屈折することから、図８に二点鎖線で示す曲面８１Ｂ２に設けられた反射層２２で反射された反射方向と同一の方向に反射する。 Specifically, when the incident light is reflected by the reflective layer 22 of the curved surface 81B, the light is reflected with respect to the tangent line of the curved surface 81B. At this time, since the light is refracted by the coating layer 23, the light is reflected in the same direction as the reflection direction reflected by the reflection layer 22 provided on the curved surface 81B2 indicated by a two-dot chain line in FIG.
　換言すると、曲面８１Ｂにおける光路長は、屈折率ｎと曲面８１Ｂの高さＨの積となることから、成形層２１Ｂは、曲率Ｒ２の曲面８１Ｂ２を有する形状、即ち、曲面８１Ｂの高さがｎ倍となる形状に視認することが可能となる。よって、視認される曲面８１Ｂの高さは、実際の曲面８１Ｂの高さよりも高い形状で視認されることとなり、表示体１２は、立体感を強調することが可能となる。 In other words, since the optical path length in the curved surface 81B is the product of the refractive index n and the height H of the curved surface 81B, the molding layer 21B has a shape having the curved surface 81B2 having the curvature R2, that is, the height of the curved surface 81B is n. It becomes possible to visually recognize the doubled shape. Therefore, the height of the visible curved surface 81B is visually recognized in a shape higher than the actual height of the curved surface 81B, and the display body 12 can enhance the stereoscopic effect.
　このように、表示体１２Ｂは、被覆層２３の屈折率を制御することで、厚さ以上の高さを疑似的に得ること、及び、当該高さを制御することが可能となる。 Thus, the display body 12B can control the refractive index of the covering layer 23 to obtain a pseudo height above the thickness and control the height.
　（第４の実施形態）
　以下、本発明に係る第４の実施形態について図９及び図１０を用いて説明する。　
　図９は、第４の実施形態に係る情報印刷物１に用いられる表示体１２Ｃの構成を示す平面図であり、図１０は、表示体１２Ｃを図９中、Ｘ－Ｘ線断面で示す断面図である。なお、第４の実施形態に係る表示体１２Ｃの構成のうち、第１の実施形態に係る表示体１２と同様の構成には、同一符号を付し、その詳細な説明は省略する。 (Fourth embodiment)
A fourth embodiment according to the present invention will be described below with reference to FIGS.
FIG. 9 is a plan view showing a configuration of a display body 12C used in the information printed matter 1 according to the fourth embodiment, and FIG. 10 is a cross-sectional view showing the display body 12C in a cross section taken along line XX in FIG. It is. In addition, the same code | symbol is attached | subjected to the structure similar to the display body 12 which concerns on 1st Embodiment among the structures of the display body 12C which concerns on 4th Embodiment, and the detailed description is abbreviate | omitted.
　図１０に示すように、表示体１２Ｃは、方形のシート状に構成される。図１０に示す表示体１２Ｃは、成形層２１Ｃと、成形層２１Ｃの一方の主面に構成される反射層２２と、成形層２１Ｃ及び反射層２２を覆う被覆層２３Ｃと、成形層２１Ｃの他方の主面に設けられる接着層２４とを有する。 As shown in FIG. 10, the display body 12C is configured in a rectangular sheet shape. The display body 12C shown in FIG. 10 includes a molding layer 21C, a reflective layer 22 formed on one main surface of the molding layer 21C, a coating layer 23C covering the molding layer 21C and the reflection layer 22, and the other of the molding layer 21C. And an adhesive layer 24 provided on the main surface.
　成形層２１Ｃは、その表面に同一の傾斜角度に構成された複数の傾斜面７１を有する複数の突起部５１を備えている。換言すると、成形層２１Ｃは、その一方の主面側の全面に亘って成形部４３Ｃが設けられる。成形層２１Ｃは、上述した成形層２１と同様の材料により構成される。 The molding layer 21 </ b> C includes a plurality of protrusions 51 having a plurality of inclined surfaces 71 configured at the same inclination angle on the surface thereof. In other words, the molding layer 21 </ b> C is provided with the molding portion 43 </ b> C over the entire surface on the one main surface side. The molding layer 21C is made of the same material as the molding layer 21 described above.
　複数の突起部５１は、同一の高さに構成される。例えば、複数の突起部５１は、主面が平坦な膜状に形成された樹脂材料からなる基材の一方の主面を切削加工又はレーザー描画機を用いた加工により構成される。 The plurality of protrusions 51 are configured at the same height. For example, the plurality of projecting portions 51 are configured by cutting or processing using a laser drawing machine on one main surface of a base material made of a resin material having a main surface formed in a flat film shape.
　突起部５１は、表示体１２Ｃの一対の外縁間に亘って設けられる。複数の突起部５１は、傾斜面７１の傾斜方向が同一方向となる形状で並列に設けられる。 The protrusion 51 is provided across a pair of outer edges of the display body 12C. The plurality of protrusions 51 are provided in parallel so that the inclined direction of the inclined surface 71 is the same direction.
　被覆層２３Ｃは、成形層２１Ｃ及び反射層２２上を覆う。被覆層２３Ｃは、入射された光の光路長と空気中を通過する光の光路長とを異ならせ、光路差を生じさせて、疑似的な距離感を観察者に与えることが可能に構成される。 The covering layer 23 </ b> C covers the molding layer 21 </ b> C and the reflective layer 22. The covering layer 23C is configured to be able to give an observer a pseudo sense of distance by making the optical path length of the incident light different from the optical path length of the light passing through the air and causing an optical path difference. The
　被覆層２３Ｃは、所定の屈折率を有し、且つ、透明または半透明な材料により構成される。被覆層２３Ｃの主面は、面方向が光の入射方向に対して直交する方向に延設する平坦状に構成される。 The covering layer 23C has a predetermined refractive index and is made of a transparent or translucent material. The main surface of the covering layer 23 </ b> C is configured to have a flat shape in which the surface direction extends in a direction orthogonal to the light incident direction.
　被覆層２３Ｃは、表示体１２Ｃで表示する情報Ｖの形状に外縁が形成された第１被覆層２３ａと、表示体１２Ｃで表示する情報Ｖの形状に内縁が形成された第２被覆層２３ｂと、を備えている。 The covering layer 23C includes a first covering layer 23a in which the outer edge is formed in the shape of the information V displayed on the display body 12C, and a second covering layer 23b in which the inner edge is formed in the shape of the information V displayed on the display body 12C. It is equipped with.
　第１被覆層２３ａ及び第２被覆層２３ｂは、異なる屈折率を有する材料により構成される。また、第１被覆層２３ａ及び第２被覆層２３ｂは、その境界が一体に接続される。 The first coating layer 23a and the second coating layer 23b are made of materials having different refractive indexes. Moreover, the boundary of the 1st coating layer 23a and the 2nd coating layer 23b is integrally connected.
　このように屈折率の異なる高屈折材料により複数の突起部５１を覆うことにより、第１被覆層２３ａにより覆われた部分と第２被覆層２３ｂにより覆われた部分とで、複数の突起部５１の間の溝７３の深さが疑似的に異なる。 By covering the plurality of protrusions 51 with the high refractive materials having different refractive indexes in this way, the plurality of protrusions 51 are divided into a portion covered by the first covering layer 23a and a portion covered by the second covering layer 23b. The depth of the groove 73 between them is pseudo-different.
　複数の溝７３の幅は一定であることから、第１被覆層２３ａの領域と、第２被覆層２３ｂの領域とにおいて、傾斜面７１の傾斜角度が、疑似的に異なることになる。結果、第１被覆層２３ａと第２被覆層２３ｂおいて、被覆層２３Ｃの主面に対して垂直方向から光がそれぞれ入射した場合、第１被覆層２３ａの領域と、第２被覆層２３ｂの領域とにおいて、反射層２２で反射された光の反射方向がそれぞれ異なる。 Since the width of the plurality of grooves 73 is constant, the inclination angle of the inclined surface 71 differs in a pseudo manner in the region of the first coating layer 23a and the region of the second coating layer 23b. As a result, in the first coating layer 23a and the second coating layer 23b, when light is incident from a direction perpendicular to the main surface of the coating layer 23C, the region of the first coating layer 23a and the second coating layer 23b The reflection direction of the light reflected by the reflective layer 22 is different between the regions.
　これにより、表示体１２Ｃは、第１被覆層２３ａが設けられた領域、即ち、情報Ｖが記された部分が０値となり、第２被覆層２３ｂが設けられた領域、即ち情報Ｖの周囲が１値となり、二値画像で情報Ｖを表示することが可能となる。 Thereby, in the display body 12C, the area where the first covering layer 23a is provided, that is, the portion where the information V is written becomes 0 value, and the area where the second covering layer 23b is provided, ie, the periphery of the information V It becomes one value, and it becomes possible to display the information V as a binary image.
　例えば、第１被覆層２３ａと第２被覆層２３ｂとの屈折率差が０．０５であって、溝７３の深さが５μｍで溝７３の間の間隔が３０μｍの場合を用いた場合には、溝７３の深さの差は疑似的に０．２５μｍとなり、傾斜面７１の傾斜角度の差は０．２８度となる。 For example, when the refractive index difference between the first covering layer 23a and the second covering layer 23b is 0.05, the depth of the groove 73 is 5 μm, and the interval between the grooves 73 is 30 μm, The difference in the depth of the groove 73 is 0.25 μm in a pseudo manner, and the difference in the inclination angle of the inclined surface 71 is 0.28 degrees.
　これにより、表示体１２Ｃを観察する距離を４００ｍｍと規定し、その距離から表示体を観察した場合には、第１被覆層２３ａ及び第２被覆層２３ｂを透過し、それぞれの傾斜面７１の全面に設けられた反射層２２で反射した２つの光は、２ｍｍ離れて観察されることとなる。 Thereby, the distance for observing the display body 12C is defined as 400 mm, and when the display body is observed from the distance, the first covering layer 23a and the second covering layer 23b are transmitted, and the entire surfaces of the respective inclined surfaces 71 are transmitted. The two lights reflected by the reflective layer 22 provided on the surface are observed 2 mm apart.
　ここで、人間の瞳孔の大きさは明るい環境下においては２ｍｍであることから、観察者は、これら２つの反射光を分離して視認することが可能である。このため、表示体１２は、二値画像として、情報Ｖを識別することができる。
（第５の実施形態）

　図１１は、第５の実施形態に係る表示体１２Ｄの各層の構成を示す断面図である。図１２は、図１１に示す表示体１２Ｄにおける光の反射挙動を説明する説明図である。なお、第５の実施形態に係る表示体１２Ｄの構成のうち、第１の実施形態に係る表示体１２と同様の構成には、同一符号を付し、その詳細な説明は省略する。 Here, since the size of the human pupil is 2 mm in a bright environment, the observer can visually recognize these two reflected lights separately. For this reason, the display body 12 can identify the information V as a binary image.

FIG. 12 is an explanatory diagram for explaining the light reflection behavior in the display body 12D shown in FIG. Note that, in the configuration of the display body 12D according to the fifth embodiment, the same components as those of the display body 12 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
　図１１に示すように、表示体１２Ｄは、方形のシート状に構成される。表示体１２Ｄは、成形層２１Ｄと、成形層２１Ｄの一方の主面に構成される反射層２２と、成形層２１Ｄ及び反射層２２を覆う被覆層２３Ｄと、成形層２１Ｄの他方の主面に設けられる接着層２４とを有する。 As shown in FIG. 11, the display body 12D is formed in a rectangular sheet shape. The display body 12D includes a molding layer 21D, a reflection layer 22 formed on one main surface of the molding layer 21D, a coating layer 23D covering the molding layer 21D and the reflection layer 22, and the other main surface of the molding layer 21D. And an adhesive layer 24 to be provided.
　成形層２１Ｄは、その表面に同一の傾斜角度に構成された複数の傾斜面７１を有する複数の突起部５１を備えている。なお、成形層２１Ｄは、上述した成形層２１と同様の材料により構成される。換言すると成形層２１Ｄは、その一方の主面側の全面に亘って成形部４３Ｄが成形される構成である。 The molding layer 21 </ b> D includes a plurality of protrusions 51 having a plurality of inclined surfaces 71 configured at the same inclination angle on the surface thereof. The molding layer 21D is made of the same material as the molding layer 21 described above. In other words, the molding layer 21D has a configuration in which the molding part 43D is molded over the entire surface on the one main surface side.
　複数の突起部５１は、同一の高さに構成される。例えば、複数の突起部５１は、主面が平坦な膜状に形成された樹脂材料からなる基材の一方の主面を切削加工又はレーザー描画機を用いた加工により構成される。 The plurality of protrusions 51 are configured at the same height. For example, the plurality of projecting portions 51 are configured by cutting or processing using a laser drawing machine on one main surface of a base material made of a resin material having a main surface formed in a flat film shape.
　被覆層２３Ｄは、成形層２１側に設けられた第１被覆層２３ｃと、表示体１２Ｄの主面側に設けられた第２被覆層２３ｄと、を備えている。 The coating layer 23D includes a first coating layer 23c provided on the molding layer 21 side, and a second coating layer 23d provided on the main surface side of the display body 12D.
　第１被覆層２３ｃ及び第２被覆層２３ｄは、透明または半透明な材料により構成される。 The first coating layer 23c and the second coating layer 23d are made of a transparent or translucent material.
　第１被覆層２３ｃ及び第２被覆層２３ｄは、異なる屈折率を有する材料により構成される。また、第１被覆層２３ｃは、並列に形成された複数の突起部５１の間の溝７３の約半分の深さを埋めるように設けられる。第１被覆層２３ａ及び第２被覆層２３ｂは、一体に積層される。 The first coating layer 23c and the second coating layer 23d are made of materials having different refractive indexes. Moreover, the 1st coating layer 23c is provided so that the about half depth of the groove | channel 73 between the some projection parts 51 formed in parallel may be filled. The first coating layer 23a and the second coating layer 23b are laminated together.
　第１被覆層２３ｃの第２被覆層２３ｄとの境界面は、面方向が光の入射方向に対して直交する方向に延設する平坦状に構成される。また、第２被覆層２３ｄの主面は、面方向が光の入射方向に対して直交する方向に延設する平坦状に構成される。 The boundary surface between the first coating layer 23c and the second coating layer 23d is formed in a flat shape in which the surface direction extends in a direction orthogonal to the light incident direction. Further, the main surface of the second coating layer 23d is configured to have a flat shape in which the surface direction extends in a direction perpendicular to the light incident direction.
　第１被覆層２３ｃは、例えば、超微細なインクジェット装置等により形成することができる。 The first coating layer 23c can be formed by, for example, an ultra-fine inkjet device or the like.
　このような構成を有する表示体１２Ｄは、表示体１２Ｄの主面に対して垂直に入射した光の反射方向を制御することができる。 The display body 12D having such a configuration can control the reflection direction of light incident perpendicularly to the main surface of the display body 12D.
　具体的には、図１２に示すように、突起部５１は、反射層２２が設けられた１つの傾斜面に第１被覆層２３ｃで覆われた部分と第２被覆層２３ｄで覆われた部分とを有している。 Specifically, as shown in FIG. 12, the protrusion 51 includes a portion covered with the first coating layer 23c and a portion covered with the second coating layer 23d on one inclined surface on which the reflective layer 22 is provided. And have.
　このため、第２被覆層２３ｄのみを透過して傾斜面７１に設けられた反射層２２で反射する光Ｌと、第２被覆層２３ｄを透過した後に第１被覆層２３ｃを透過して傾斜面７１に設けられた反射層２２で反射する光Ｌとは、それぞれ光の反射方向が異なる。 For this reason, the light L that is transmitted only through the second coating layer 23d and reflected by the reflection layer 22 provided on the inclined surface 71, and the first coating layer 23c after being transmitted through the second coating layer 23d and the inclined surface The light reflection direction differs from the light L reflected by the reflective layer 22 provided in 71.
　このように、１つの傾斜面７１において、２つの方向に光Ｌの反射方向を制御することができるため、複数の突起部５１の傾斜角度を変えることなく観察者に異なった見え方を提供することができる。 As described above, since the reflection direction of the light L can be controlled in two directions on one inclined surface 71, a different view is provided to the observer without changing the inclination angle of the plurality of protrusions 51. be able to.
　なお、本発明は上述した各実施形態に限定されない。例えば、表示体は、上述した第４の実施形態に係る表示体１２Ｃの被覆層２３Ｃ及び第５の実施形態に係る表示体１２Ｄの被覆層２３Ｄを組み合わせる構成であってもよい。即ち、図１３及び図１４に示す第６の実施形態に係る表示体１２Ｅの構成のように、成形層２１Ｅは、異なる屈折率を有する第１被覆層２３ｅ、第２被覆層２３ｆ、第３被覆層２３ｇ、第４被覆層２３ｈを、成形層２１Ｅの面方向及び厚み方向で配置する構成であってもよい。 Note that the present invention is not limited to the above-described embodiments.
