The first light-shielding layer 3 is laminated on one surface side of the light-transmissive support 1 having a thickness d, and the second light-shielding layer 5 is laminated on the other surface side of the light-transmissive support 1. is there. The shape formed by the opening portion 3a of the first light shielding layer 3 and the shape formed by the second light shielding layer 5 are substantially matched, and the light source 6 is disposed on the other surface side of the light transmissive support 1. Then, visual observation is performed from the side of the observer 7 away from the light transmissive support 1 by L.
　光透過性支持体１としては、透明樹脂のみ、拡散性樹脂のみ、透明樹脂層と拡散性樹脂層との積層の３種類の構成のいずれかを選択することができる。 As the light-transmitting support 1, any one of three types of configurations including only a transparent resin, only a diffusible resin, and a laminate of a transparent resin layer and a diffusible resin layer can be selected.
　光透過性支持体１を透明樹脂のみで構成する場合、ポリカーボネート、ポリプロピレン、発泡ポリプロピレン、ポリエチレンテレフタレート、ポリスチレン、メタクリル・スチレン共重合体、アクリルニトリル・スチレン共重合体、ポリメタクリル酸メチルまたはアクリルを利用することができる。この時の光透過性支持体１の厚さは遮光層を形成する工程などにおける作業性から、０．０５ｍｍ以上である必要があり、一般的には１ｍｍ以上が用いられる。情報表示機器筐体内に組み込んだときに空間的制約を受けないためには、厚さ５ｍｍ以下であることが好ましい。また、透明樹脂のみで構成すると、光源６からの光が光透過性支持体１を透過する際の光量の損失を少なく出来るため、光源６の点灯時には、より明るく文字・絵柄を表示することができる。 When the transparent substrate 1 is composed of only transparent resin, polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer, polymethyl methacrylate or acrylic are used. can do. At this time, the thickness of the light-transmitting support 1 needs to be 0.05 mm or more from the viewpoint of workability in the step of forming a light shielding layer, and generally 1 mm or more is used. The thickness is preferably 5 mm or less so as not to be restricted spatially when incorporated in the information display device casing. Further, when the light source 6 is composed only of the transparent resin, the loss of the amount of light when the light from the light source 6 passes through the light-transmissive support 1 can be reduced. Therefore, when the light source 6 is turned on, characters and pictures can be displayed brighter. it can.
　光透過性支持体１を拡散性樹脂のみで構成する場合、球形または無定形の形状であり有機又は無機からなる光拡散性微粒子を含んだポリカーボネート、ポリスチレン、メタクリル・スチレン共重合体、アクリルのうち少なくともいずれかを含む有機系樹脂を利用することができる。
　この時の光透過性支持体１の厚さは遮光層を形成する工程などにおける作業性から、０．０５ｍｍ以上である必要があり、一般的には１ｍｍ以上が用いられる。情報表示機器筐体内に組み込んだときに空間的制約を受けないためには、５ｍｍ以下が好ましい。また、拡散性樹脂のみで構成することにより、光源６からの直接入射光の一部が拡散性樹脂で散乱されて、第一の遮光層３の開口部周縁から観察者７側に出るために、間接光の輝度を高めることができる。 When the light-transmitting support 1 is composed only of a diffusible resin, it is a polycarbonate, polystyrene, methacryl / styrene copolymer, or acrylic that has a spherical or amorphous shape and contains organic or inorganic light diffusing fine particles. An organic resin containing at least one of them can be used.
At this time, the thickness of the light-transmitting support 1 needs to be 0.05 mm or more from the viewpoint of workability in the step of forming a light shielding layer, and generally 1 mm or more is used. 5 mm or less is preferable in order not to be spatially limited when incorporated in the information display device casing. Further, by constituting only the diffusible resin, a part of the direct incident light from the light source 6 is scattered by the diffusible resin, and is emitted from the periphery of the opening of the first light shielding layer 3 to the viewer 7 side. The brightness of indirect light can be increased.
　光透過性支持体１を透明樹脂層と拡散性樹脂層との積層構成にする場合、透明樹脂層にはポリカーボネート、ポリプロピレン、発泡ポリプロピレン、ポリエチレンテレフタレート、ポリスチレン、メタクリル・スチレン共重合体、アクリルニトリル・スチレン共重合体、ポリメタクリル酸メチルまたはアクリルを、拡散性樹脂層には球形または無定形の形状であり有機又は無機からなる光拡散性微粒子を含んだポリカーボネート、ポリスチレン、メタクリル・スチレン共重合体、アクリルのうち少なくともいずれかを含む有機系樹脂を利用することができる。 When the light-transmissive support 1 has a laminated structure of a transparent resin layer and a diffusible resin layer, the transparent resin layer includes polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / Styrene copolymer, polymethyl methacrylate or acrylic, polycarbonate, polystyrene, methacryl / styrene copolymer containing light diffusing fine particles consisting of spherical or amorphous and organic or inorganic in the diffusible resin layer, An organic resin containing at least one of acrylics can be used.
　この時の光透過性支持体１の厚さは遮光層を形成する工程などにおける作業性から、０．０５ｍｍ以上である必要があり、一般的には１ｍｍ以上が用いられる。情報表示機器筐体内に組み込んだときに空間的制約を受けないために５ｍｍ以下が好ましい。また、拡散性樹脂層を含む構成であることにより、光源６からの直接入射光の一部が拡散性樹脂層で散乱されて、第一の遮光層３の開口部３ａ周縁から観察者７側に出るために、間接光の輝度を高めることができる。
　この時の透明樹脂層と拡散性樹脂層の配置の順序、すなわち、どちらが観察者７側で、どちらが光源６側に配置されるかは、どちらであっても構わない。 At this time, the thickness of the light-transmitting support 1 needs to be 0.05 mm or more from the viewpoint of workability in the step of forming a light shielding layer, and generally 1 mm or more is used. It is preferably 5 mm or less so as not to be restricted by space when incorporated in the information display device casing. Further, since the diffusing resin layer is included, a part of the direct incident light from the light source 6 is scattered by the diffusing resin layer, and the viewer 7 side from the periphery of the opening 3a of the first light shielding layer 3 Therefore, the brightness of indirect light can be increased.
The order of arrangement of the transparent resin layer and the diffusible resin layer at this time, that is, which is arranged on the viewer 7 side and which is arranged on the light source 6 side may be either.
　光透過性支持体１の一方の面側（観察者７側）に第一の遮光層３を積層する。第一の遮光層３はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることもできる。第一の遮光層３は、文字や絵柄などの所定のパターンを有した形状に形成される。このとき、遮光層３が形成されている部分が文字や絵柄などの図柄を表し、形成されていない開口部３ａが背景を表していても良いし、逆に、遮光層３が形成されている部分が背景を表し、形成されていない開口部３ａが文字や絵柄などの図柄を表していても良い。第一の遮光層３には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。遮光層３の厚みに制限は無いが、５μｍ～３０μｍにすると遮光効果を得やすい。 The first light shielding layer 3 is laminated on one surface side (observer 7 side) of the light transmissive support 1. The first light shielding layer 3 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing. The first light shielding layer 3 is formed in a shape having a predetermined pattern such as a character or a picture. At this time, the portion where the light shielding layer 3 is formed may represent a pattern such as a character or a picture, and the opening 3a that is not formed may represent the background, or conversely, the light shielding layer 3 is formed. The portion may represent the background, and the opening 3a that is not formed may represent a pattern such as a character or a pattern. Although it is desirable to use black ink for the first light shielding layer 3, it is not limited to black ink as long as it has a light shielding effect. The thickness of the light shielding layer 3 is not limited, but a light shielding effect is easily obtained when the thickness is 5 μm to 30 μm.
　光透過性支持体１の他方の面側（光源６側）に第二の遮光層５を設ける。
第二の遮光層５はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることもできる。
　第二の遮光層５は、前述の第一の遮光層３が形成されていない開口部３ａ領域とほぼ同形状のパターンを有し、第一の遮光層３の開口部３ａとほぼ同じ位置に位置合わせされて設けられている。したがって、第二の遮光層５が形成されていない開口部５ａは、第一の遮光層３が形成されている部分とほぼ同形状のパターンを有し、第一の遮光層３とほぼ同じ位置に位置合わせされて設けられていることになる。 A second light shielding layer 5 is provided on the other surface side (light source 6 side) of the light transmissive support 1.
The second light shielding layer 5 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
The second light shielding layer 5 has a pattern substantially the same shape as the opening 3a region where the first light shielding layer 3 is not formed, and is substantially at the same position as the opening 3a of the first light shielding layer 3. Aligned and provided. Accordingly, the opening 5a in which the second light shielding layer 5 is not formed has a pattern having substantially the same shape as the portion in which the first light shielding layer 3 is formed, and is substantially in the same position as the first light shielding layer 3. It is provided in alignment with.
　第二の遮光層５には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。遮光層３の厚みに制限は無いが、５μｍ～３０μｍにすると遮光効果を得やすい。
　光源６が点灯した際には、第二の遮光層５が形成されている領域では遮光層５により遮光され、第一の遮光層３が形成されている領域では遮光層３により遮光されるため、大部分の直接光は観察者７側に届くことがなく、第二の遮光層５側の開口部５ａを通過した光のうちの一部が、第一の遮光層３の開口部３ａ周縁から観察者７側に届く。それにより、第一の遮光層３が形成されている領域の外周に、光が広がるのが視認され、文字・絵柄等が美しく表示される。 Although it is desirable to use black ink for the second light shielding layer 5, it is not limited to black ink as long as it has a light shielding effect. The thickness of the light shielding layer 3 is not limited.
When the light source 6 is turned on, light is blocked by the light blocking layer 5 in the region where the second light blocking layer 5 is formed, and light is blocked by the light blocking layer 3 in the region where the first light blocking layer 3 is formed. Most of the direct light does not reach the viewer 7 side, and part of the light that has passed through the opening 5a on the second light shielding layer 5 side is the periphery of the opening 3a of the first light shielding layer 3 To the observer 7 side. Thereby, it is visually recognized that light spreads on the outer periphery of the region where the first light shielding layer 3 is formed, and characters, designs, etc. are displayed beautifully.
　光源６からの光は、情報表示パネル８の第二の遮光層５の開口部５ａから光透過性支持体１内に入射する。光透過性支持体１の観察者７側の面に到達した光のほとんどは第一の遮光層３によって遮断されるが、第一の遮光層３の開口部３ａの周辺部分が縁取りしたように光ることで木漏れ日のような間接光の効果をもたせることが出来る。このような木漏れ調の効果の光は、光源から直接観察される光ではなく、反射や散乱した光の成分であるため間接照明のような効果をもたらす事ができる。この間接光の成分は、光透過性支持体１に拡散性を持たせたり、光透過性支持体１と遮光層３または遮光層５の間に光を散乱反射する層を設けたりすることで強くすることが出来る。 Light from the light source 6 enters the light transmissive support 1 from the opening 5 a of the second light shielding layer 5 of the information display panel 8. Although most of the light reaching the surface of the light-transmissive support 1 on the side of the observer 7 is blocked by the first light shielding layer 3, the peripheral portion of the opening 3a of the first light shielding layer 3 is bordered. The effect of indirect light such as sunbeams can be given by shining. The light having such a tree leakage effect is not light directly observed from the light source but is a component of reflected or scattered light, and thus can provide an effect like indirect illumination. This indirect light component can be obtained by making the light transmissive support 1 diffusive, or by providing a layer that scatters and reflects light between the light transmissive support 1 and the light shielding layer 3 or the light shielding layer 5. Can be strong.
　図２は、本発明の情報表示パネル８の第二の実施形態の断面図を示したものである。
　厚さｄの光透過性支持体１の一方の面側に第一の遮光層３が積層され、光透過性支持体１の他方の面側に第二の遮光層５が積層されたものである。第一の遮光層の開口部分３ａに対して第二の遮光層が幅ｗだけ大きい情報表示パネルである。 FIG. 2 shows a sectional view of a second embodiment of the information display panel 8 of the present invention.
The first light-shielding layer 3 is laminated on one surface side of the light-transmissive support 1 having a thickness d, and the second light-shielding layer 5 is laminated on the other surface side of the light-transmissive support 1. is there. In the information display panel, the second light shielding layer is larger by the width w than the opening 3a of the first light shielding layer.
　光透過性支持体１の前記他方の面側に光源６が配置し、光透過性支持体１からＬだけ離れた観察者７側から目視を行うことになる。 The light source 6 is disposed on the other surface side of the light transmissive support 1, and viewing is performed from the viewer 7 side away from the light transmissive support 1 by L.
　光透過性支持体１、第一の遮光層３および第二の遮光層５の材料、作成方法は、前述したのと同様である。 The materials and production methods of the light transmissive support 1, the first light shielding layer 3, and the second light shielding layer 5 are the same as described above.
　情報表示パネル８に対して斜めに観察すると、光透過性支持体１の厚みの影響により二つの遮光層に遮られること無く直接観察される光が生じる。この光は、金環食のように第一の遮光層３による開口部３ａのエッジが明るく縁取るように観察される。このエッジの明るく光る部分の幅は観察する角度が斜めになるほど広くなる。 When observed obliquely with respect to the information display panel 8, light that is directly observed without being blocked by the two light shielding layers is generated due to the influence of the thickness of the light transmissive support 1. This light is observed so that the edge of the opening 3a by the first light-shielding layer 3 is brightly rimmed like an annulus. The width of the bright portion of the edge becomes wider as the angle of observation becomes oblique.
　情報表示パネル８を両目で観察した場合、右目と左目で情報表示パネル８を観察する角度が異なるため、左右の目に観察されるエッジの明るく光る部分の幅が異なって見える。このことは、左右の目で視差のある像を観察することを示し、その視差の効果によって観察者に情報表示パネルを立体的な形状と認識させることが可能になる。視差の効果がもっとも高まるのは、明るく光るエッジを片方の目で観察し、もう片方の目では観察できない場合である。これは、以下のような条件を満たしたときに実現できる。 When the information display panel 8 is observed with both eyes, since the angle at which the information display panel 8 is observed is different between the right eye and the left eye, the widths of the brightly illuminated portions of the left and right eyes appear to be different. This indicates that an image with parallax is observed with the left and right eyes, and the effect of the parallax enables the viewer to recognize the information display panel as a three-dimensional shape. The parallax effect is most enhanced when the bright shining edge is observed with one eye and cannot be observed with the other eye. This can be realized when the following conditions are satisfied.
　図２に示すように第一の遮光層３の開口部３ａより第二の遮光層５が幅ｗだけ大きいとし、光透過性支持体１の厚みをｄとする。情報表示パネル８から垂直の位置にて観察した場合、光源６からの光は遮光層３または遮光層５のどちらかによって遮られるため、光源からの直接の光を観察することはない。視点を徐々に移動して斜めにし、その角度が
tan-1（ｗ／ｄ）
を超えると明るく光るエッジを観察することになる。 As shown in FIG. 2, the second light-shielding layer 5 is larger than the opening 3a of the first light-shielding layer 3 by a width w, and the thickness of the light-transmissive support 1 is d. When observed from a position perpendicular to the information display panel 8, the light from the light source 6 is blocked by either the light shielding layer 3 or the light shielding layer 5, so that direct light from the light source is not observed. Move the viewpoint gradually to make it diagonal,
tan -1 (w / d)
Beyond, you will observe brightly shining edges.
　ここで、観察者の両目の間隔をa、観察者の目と情報表示パネル８までの距離をLとすると、観察者の両目の見込み角θは次の式で表される（図３参照）。
tanθ＝a／L Here, if the distance between the eyes of the observer is a and the distance between the eyes of the observer and the information display panel 8 is L, the prospective angle θ of the eyes of the observer is expressed by the following equation (see FIG. 3). .
tanθ = a / L
　この両目の見込み角θよりも、tan-1（ｗ／ｄ）で示される角度が小さくなるように設定すれば、明るく光るエッジを片方の目では観察できるが、もう片方の目では観察できないことになり、より立体感を感じる効果を高めることが出来る。 If the angle shown by tan -1 (w / d) is set to be smaller than the prospective angle θ of both eyes, a bright shining edge can be observed with one eye, but not with the other eye. The effect of feeling a three-dimensional effect can be enhanced.
　また、図４は、本発明の情報表示パネル８の第三の実施形態の断面図を示したものである。
　本実施形態においては、第一の遮光層３の開口部３ａより第二の遮光層５が小さく（幅－ｗだけ大きい）、光透過性支持体１の厚みがｄの情報表示パネルである。情報表示パネル８から垂直に観察した場合、第一の遮光層３のエッジ部分の光は、遮光層３および遮光層５のいずれによっても遮られないため、光源６からの直接の光を観察することになる。視点を移動して徐々に斜めにし、その角度が
tan-1（|ｗ|／ｄ）
を超えると、光源６からの直接の光はどちらかの遮光層で遮られるためエッジ部の光は見えなくなる。 FIG. 4 shows a sectional view of a third embodiment of the information display panel 8 of the present invention.
In this embodiment, the second light-shielding layer 5 is smaller than the opening 3a of the first light-shielding layer 3 (by a width −w), and the thickness of the light-transmissive support 1 is d. When observed vertically from the information display panel 8, the light at the edge portion of the first light shielding layer 3 is not blocked by either the light shielding layer 3 or the light shielding layer 5, so the direct light from the light source 6 is observed. It will be. Move the viewpoint to make it gradually diagonal,
tan -1 (| w | / d)
If it exceeds, the direct light from the light source 6 is blocked by one of the light shielding layers, so that the light at the edge portion becomes invisible.
　観察者７の両目の間隔をa、観察者７の目と情報表示パネル８までの距離をLとすると、観察者７の両目の見込み角θは次の式で表される（図３参照）。
tanθ＝a／L When the distance between the eyes of the observer 7 is a and the distance between the eyes of the observer 7 and the information display panel 8 is L, the prospective angle θ of the eyes of the observer 7 is expressed by the following formula (see FIG. 3). .
tanθ = a / L
　この両目の見込み角θより、
tan-1（|ｗ|／ｄ）
で示される角度が小さくなるように設定すれば、明るく光るエッジを片方の目では観察できるが、もう片方の目では観察できないことになり、より立体感を感じる効果を高めることが出来る。 From the prospective angle θ of both eyes,
tan -1 (| w | / d)
If the angle indicated by is set to be small, a bright and bright edge can be observed with one eye, but cannot be observed with the other eye, and the effect of feeling a three-dimensional effect can be enhanced.
　以上のことから
　－ 1×d×a／L　≦　w　≦　d×a／L
　の関係を満たせば高い立体感の効果を得ることが出来る。 From the above-1 x d x a / L ≤ w ≤ d x a / L
If the relationship is satisfied, a high three-dimensional effect can be obtained.
　一般に両目の間隔は、約65ｍｍ程度であると言われ、また乗用車の運転者の目の位置と情報表示パネルまでの距離は600～1200ｍｍ程度である。 Generally, the distance between both eyes is said to be about 65 mm, and the distance between the eyes of the passenger of the passenger car and the information display panel is about 600 to 1200 mm.
　そこでa=65, L=800 とすると、乗用車等の場合、
-0.081×d　≦　w　≦　0.081×d
を満たせば高い立体感の効果を得ることが出来る。 So, if a = 65, L = 800,
-0.081 × d ≦ w ≦ 0.081 × d
If the condition is satisfied, a high three-dimensional effect can be obtained.
　また、視差は頭の位置を固定した場合の両眼視差と、頭の位置を動かした際に生じる動視差がある。乗用車の運転席の場合、運転者の頭の動く範囲は約300ｍｍ程度である。そこで、動視差を考慮し、a=300, L=800 とすると、
　-0.38×d　≦　w　≦　0.38×d　
を満たせば高い立体感の効果を得ることが出来る。 In addition, parallax includes binocular parallax when the head position is fixed and dynamic parallax that occurs when the head position is moved. In the case of a passenger seat of a passenger car, the range of movement of the driver's head is about 300 mm. So, considering dynamic parallax, if a = 300, L = 800,
-0.38 × d ≦ w ≦ 0.38 × d
If the condition is satisfied, a high three-dimensional effect can be obtained.
　図５は、本発明の情報表示パネル８の第四の実施形態の断面図を示したものである。
　第二～第三の実施形態においては、第一の遮光層３の開口部３ａより第二の遮光層５が大きい場合と小さい場合を示したが、図５に示すようにある領域では第一の遮光層３の開口部３ａより第二の遮光層５が大きく、ある領域では第一の遮光層３の開口部３ａより第二の遮光層５が小さいものでも、上記条件を満たせば高い立体感を得ることが可能である。 FIG. 5 shows a sectional view of the fourth embodiment of the information display panel 8 of the present invention.
In the second to third embodiments, the case where the second light-shielding layer 5 is larger and smaller than the opening 3a of the first light-shielding layer 3 is shown. However, in a certain region as shown in FIG. Even if the second light-shielding layer 5 is larger than the opening 3a of the light-shielding layer 3 and the second light-shielding layer 5 is smaller than the opening 3a of the first light-shielding layer 3 in a certain region, a high three-dimensional structure is obtained if the above conditions are satisfied It is possible to get a feeling.

And is aligned and provided at substantially the same position as the opening 3a.

　そして、本発明の情報表示パネル８の他方の面側に１０００ｃｄ/ｍ２のＬＥＤ光源を置き、Ｌの距離から観察した。この時の観察者の両目の間隔はａとする。 Example 1 of the present invention will be specifically described below. FIG. 6 shows an embodiment of the information display panel 8 of the present invention. As a light-transmissive support 1, a first reflective layer 2 of white ink and a first light-shielding layer 3 of black ink are formed by screen printing on one surface of polycarbonate having a thickness d, and screen printing is performed on the other surface. A second light-shielding layer 5 of black ink was formed at a position where the first reflective layer 2 and the width w were spaced apart from each other. In this example, the first reflective layer 2 and the first light shielding layer 3 were formed in a character shape, and the second light shielding layer 5 was formed as a background portion.
Then, an LED light source of 1000 cd / m 2 was placed on the other surface side of the information display panel 8 of the present invention and observed from a distance L. The distance between the eyes of the observer at this time is a.
　以上の構成で、光透過性支持体１の厚さｄを変えた際の、第一の反射層２、および第一の遮光層３外周部からの、間接光の見え方の良し悪しを評価した結果を、表１に示す。 With the above configuration, the quality of the appearance of indirect light from the outer periphery of the first reflective layer 2 and the first light shielding layer 3 when the thickness d of the light transmissive support 1 is changed is evaluated.

　ここで、光透過性支持体１の厚さｄは、情報表示機器筺体内の空間的な設計の制約上、好ましいのが1～５ｍｍの範囲であることから、1～５ｍｍをパラメータとして選択している。一般的な自動車のインストルメントパネルから観察者までの距離が６００～１２００ｍｍであることから、Ｌ＝８００ｍｍとしている。また、一般的な大人の両目の間隔が５０～８０ｍｍであることから、a＝６５ｍｍとしている。 Here, the thickness d of the light transmissive support 1 is preferably in the range of 1 to 5 mm because of spatial design constraints in the information display device housing, so 1 to 5 mm is selected as a parameter. ing. Since the distance from a general automobile instrument panel to an observer is 600 to 1200 mm, L = 800 mm. Since the distance between both eyes of a general adult is 50 to 80 mm, a = 65 mm.
　なお、間接光の見え方の評価は目視による官能評価にて行い、文字外周部の明るさを１～５の５段階で評価し（良い＝５、・・・、悪い＝１）、それぞれの評価が３以上で合格とする。 In addition, the appearance of indirect light is evaluated by visual sensory evaluation, and the brightness of the outer periphery of the character is evaluated in five levels from 1 to 5 (good = 5,..., Bad = 1) The evaluation is 3 or more and passed.
　図６の構成で、第一の反射層２の波長３８０－７８０ｎｍの光に対する反射率、第一の遮光層３の全光線透過率、第二の遮光層５の全光線透過率、光透過性支持体１のヘイズ値のパラメータをそれぞれ変えた際の文字部すなわち第一の反射層２、第一の遮光層３外周部の間接光の見え方を評価した結果を、表２に示す。 In the configuration of FIG. 6, the reflectance of the first reflective layer 2 with respect to light having a wavelength of 380 to 780 nm, the total light transmittance of the first light shielding layer 3, the total light transmittance of the second light shielding layer 5, and the light transmittance. Table 2 shows the results of evaluating the appearance of the indirect light at the outer periphery of the character portion, that is, the first reflective layer 2 and the first light shielding layer 3, when the parameters of the haze value of the support 1 are changed.
　ここで、全光線透過率Ｔｔとは可視光線及び紫外線の全入射光量で試験片を通った全光量を割った値を百分率で示したものである。また、ヘイズ値は光源からの直進光線を除いた拡散光線の透過率ＴｄをＴｔで割った値を百分率で示したものである。

　表２に示した結果から、文字外周部での間接光の見え方を良くするためには、第一の反射層２の波長３８０－７８０ｎｍの光に対する反射率が６０％以上９８％以下であることが必要なことが確認できる。反射率が６０％未満であると第一の反射層２で反射される光量が少なく、従って、文字外周部に漏れてくる光量が少なくなるためと推測される。 From the results shown in Table 2, in order to improve the appearance of indirect light at the outer periphery of the character, the reflectance of the first reflective layer 2 with respect to light with a wavelength of 380 to 780 nm is 60% or more and 98% or less. It can be confirmed that it is necessary. If the reflectance is less than 60%, the amount of light reflected by the first reflective layer 2 is small, and therefore, it is presumed that the amount of light leaking to the outer periphery of the character is small.
　表２に示した結果から、文字外周部での間接光の見え方を良くするためには、第一の遮光層３の全光線透過率が０％以上２０％以下でなければならないことが確認できる。全光線透過率が２０％を超えると第一の遮光層３での遮光が不十分なものとなるために文字部分が明るく見え、文字外周部とのコントラストが低下して間接光の見え方の評価が悪くなるものと推測される。 From the results shown in Table 2, it is confirmed that the total light transmittance of the first light shielding layer 3 must be 0% or more and 20% or less in order to improve the appearance of indirect light at the outer periphery of the character. it can. If the total light transmittance exceeds 20%, light shielding by the first light shielding layer 3 becomes insufficient, so that the character portion looks bright and the contrast with the outer periphery of the character is lowered, so that the indirect light is visible. It is estimated that the evaluation will worsen.
　表２に示した結果から、文字外周部での間接光の見え方を良くするためには、第二の遮光層５の全光線透過率が０％以上２０％以下でなければならないことが確認できる。全光線透過率が２０％を超えると第二の遮光層５での遮光が不十分になって背景部分から光が透過し、文字外周部とのコントラストが低下して間接光の見え方の評価が悪くなるものと推測される。 From the results shown in Table 2, it is confirmed that the total light transmittance of the second light-shielding layer 5 must be 0% or more and 20% or less in order to improve the appearance of indirect light at the outer periphery of the character. it can. If the total light transmittance exceeds 20%, the light shielding by the second light shielding layer 5 becomes insufficient and light is transmitted from the background portion, and the contrast with the outer peripheral portion of the character is lowered to evaluate the indirect light appearance. Is estimated to be worse.
　表２に示した結果から、光透過性支持体１のヘイズ値が上がるほど、文字外周部の間接光の見え方の評価が向上することが確認できる。ヘイズ値が上がると第一の反射層２から漏れる光に光透過性支持体１から出る拡散光が加わるためと推測される。 From the results shown in Table 2, it can be confirmed that as the haze value of the light transmissive support 1 is increased, the evaluation of the appearance of the indirect light on the outer periphery of the character is improved. When the haze value is increased, it is presumed that diffused light emitted from the light-transmissive support 1 is added to light leaking from the first reflective layer 2.
　光透過性支持体１に、第一の反射層２、第一の遮光層３および第二の遮光層５を形成し、第一の反射層２の波長３８０－７８０ｎｍの光に対する反射率が８０％、第一の遮光層３の全光線透過率が０％、第二の遮光層４の全光線透過率が０％、光透過性支持体１のヘイズ値が９２％の情報表示パネルを使用すると、文字・絵柄外周部に美しい間接光を作り出すことができ、意匠性に優れた表示をすることができた。 The first reflective layer 2, the first light shielding layer 3, and the second light shielding layer 5 are formed on the light transmissive support 1, and the reflectance of the first reflective layer 2 with respect to light having a wavelength of 380 to 780 nm is 80. %, The total light transmittance of the first light shielding layer 3 is 0%, the total light transmittance of the second light shielding layer 4 is 0%, and the haze value of the light transmissive support 1 is 92%. As a result, beautiful indirect light could be created on the outer periphery of the character / picture, and a display with excellent design could be achieved.

　そして、本発明の情報表示パネルの他方の面側に１０００ｃｄ/ｍ２のＬＥＤ光源を置き、Ｌの距離から観察した。この時の観察者の両目の間隔はａとする。 Example 2 of the present invention will be specifically described. FIG. 9 shows an embodiment of the information display panel 8 of the present invention. The first reflective layer 2 and the first light-shielding layer 3 are formed on one surface of a polycarbonate having a thickness d as a base material by screen printing, and the first reflective layer 2 and the width w are formed on the other surface by screen printing. A second reflective layer 4 and a second light-shielding layer 5 were formed at positions to be reversed with an interval. In this example, the first reflective layer 2 and the first light shielding layer 3 were formed in the shape of letters, and the second reflective layer 4 and the second light shielding layer 5 were formed as background portions.
Then, an LED light source of 1000 cd / m 2 was placed on the other surface side of the information display panel of the present invention and observed from a distance L. The distance between the eyes of the observer at this time is a.

　表４に示した結果から、文字外周部での間接光の見え方を良くするためには、第一の反射層２の波長３８０－７８０ｎｍの光に対する反射率が６０％以上９８％以下であることが必要なことが確認できる。反射率が６０％未満であると反射層２で反射される光量が少なく、従って、文字外周部に漏れる光量が少ないためと推測される。 From the results shown in Table 4, in order to improve the appearance of indirect light at the outer periphery of the character, the reflectance of the first reflective layer 2 with respect to light with a wavelength of 380 to 780 nm is 60% or more and 98% or less. It can be confirmed that it is necessary. If the reflectance is less than 60%, the amount of light reflected by the reflective layer 2 is small, and therefore it is presumed that the amount of light leaking to the outer periphery of the character is small.
　表４に示した結果から、文字外周部での間接光の見え方を良くするためには、第一の遮光層３の全光線透過率が０％以上２０％以下でなければならないことが確認できる。全光線透過率が２０％を超えると第一の遮光層３での遮光が不十分なものとなるために文字部分が明るく見え、文字外周部とのコントラストが低下して間接光の見え方の評価が悪くなるものと推測される。 From the results shown in Table 4, it is confirmed that the total light transmittance of the first light-shielding layer 3 must be 0% or more and 20% or less in order to improve the appearance of indirect light at the outer periphery of the character. it can.

It can be confirmed that it is necessary. If the reflectance is less than 40%, the light reflected by the first reflective layer 2 and the light incident on the second reflective layer 4 cannot be sufficiently reflected, so that the amount of light at the outer periphery of the character is reduced and the sunbeams feeling is worsened.

　情報表示パネルの背面に配置される光源としては、各種ランプ（各種電球ランプ、ＬＥＤ光源）や面光源を利用することが出来る。特にエッジライト式光源と導光板からなる面光源は、冷陰極管などの線光源からアクリルなどの導光板内に導かれた光を導光板内の全反射を用いて導光板全面に導き、印刷などでつけられた反射ドットに当たった光がその進路を変え、全反射角よりも小さい角度になった光が導光板表面から出てくることを利用して、導光板全面が均一に光るようにしたものである。このような面光源を、情報表示パネルの背面に配置される光源として利用すると、情報表示パネル全体を均一に照明することができ、観察者が読み取りしやすいという利点がある。 As the light source arranged on the back surface of the information display panel, various lamps (various bulb lamps, LED light sources) and surface light sources can be used. In particular, the surface light source consisting of an edge light type light source and a light guide plate guides the light guided from a linear light source such as a cold cathode tube into the light guide plate such as acrylic to the entire surface of the light guide plate using total reflection in the light guide plate. By using the fact that the light hitting the reflection dots attached by the light changes its path and the light with an angle smaller than the total reflection angle emerges from the surface of the light guide plate, the entire surface of the light guide plate can be illuminated uniformly. It is a thing. When such a surface light source is used as a light source disposed on the back surface of the information display panel, there is an advantage that the entire information display panel can be uniformly illuminated and is easily read by an observer.
