Exemplary embodiments of an information display panel according to the present invention will be described below in detail with reference to the drawings.
FIG. 1 is a cross-sectional view of a laminated sheet 4 for an information display panel 5 according to a first embodiment of the present invention, taken along a plane perpendicular to the sheet extending direction. (A) shows each layer separated for easy understanding of the order of lamination, and (B) shows a state in which the layers are actually laminated.
As shown in FIG. 1, the laminated sheet 4 includes a first region 1, a second region 2, and a third region that are adjacent to the first region 1 and separated from each other, as viewed from the sheet thickness direction. Divided into three.
A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 4.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 1, an observer 7 views from one surface side of a light-transmissive support 8, and the light source 6 is installed on the other surface side of the support 8.

A first diffusion layer 31 and a fourth decorative layer 17 are sequentially stacked in the first region 1 on the surface of the support 8 on the viewer 6 side.
In addition, the second diffusion layer 32, the second reflection layer 11, and the second decoration layer 12 are sequentially laminated in the second region 2 on the surface of the support 8 on the viewer 6 side.
Further, the second diffusion layer 32, the third reflective layer 13, the second light shielding layer 14, the second decorative layer 15, in the third region 3 of the surface of the support 8 on the viewer 6 side, The transparent decoration layer 16 is laminated | stacked in order.
A first reflective layer 21, a first light-shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated in the first region 1 on the surface of the support 8 on the light source 6 side.
Further, a light transmissive colored layer 24 is provided in the second region 2 of the surface of the support 8 on the light source 6 side.
Further, a fourth reflective layer 22, a first light shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated on the third region 3 in the surface of the support 8 on the light source 6 side.

The support 8 can be composed of only a transparent resin, can be composed of only a diffusible resin, or can be composed of a laminate of a transparent resin layer and a diffusible resin layer.
Here, the haze value of the support 4 is desirably 12% or more and 92% or less.
When the haze value of the support 4 is less than 12%, the light that enters the support 4 and diffuses and reflects and passes through the first region 1 is reduced, which causes a disadvantage that the brightness of the indirect light is reduced. It is.

  When the support 8 is composed only of a transparent resin, polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer, polymethyl methacrylate or acrylic may be used. it can. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. Further, since the loss of the light amount in the support 8 can be reduced if it is composed only of the transparent resin, it is possible to display characters and designs brighter when the light source 6 is turned on.

  When the support 8 is composed only of a diffusible resin, it is a spherical or amorphous shape, and an organic resin containing at least one of polycarbonate, PS, MS, and acryl containing organic or inorganic light diffusing fine particles. Can be used. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. In addition, since only a part of the direct incident light from the light source 6 is diffused by the diffusion resin by being composed only of the diffusion resin, the second reflection layer 11, the third reflection layer 13, and the first region 1 are emitted. The amount of indirect light can be increased.

When the support 8 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. Polymer, polymethylmethacrylate or acrylic, and at least one of polycarbonate, polystyrene, methacrylstyrene copolymer, acrylic containing light diffusing fine particles made of organic or inorganic in a sphere or amorphous shape in the diffusible resin layer Any organic resin containing any of them can be used. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. Further, since the structure includes the diffusion resin layer, a part of the direct incident light from the light source 6 is diffused by the diffusion resin layer, and the second reflection layer 11, the third reflection layer 13, and the first region 1 are diffused. The amount of indirect light can be increased in order to go in the direction of the observer.
Here, the diffusible resin layer is preferably a resin having a haze value of 12% or more and 92% or less. When the haze value of the diffusible resin layer is less than 12%, the light that enters the support and diffuses and reflects and passes through the first region 1 is reduced, so that the luminance of indirect light is lowered. Because.

Next, the laminated structure on the viewer 6 side of the support 8 will be described in detail.
The first diffusion layer 31 is disposed in the first region of the surface of the support 8 on the viewer 6 side.
The first diffusion layer 31 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.
Although it is desirable to use a transparent ink for the first diffusion layer 31, it is not limited to the transparent ink as long as it has a light diffusion effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a diffusion effect will come out easily.
Further, it is desirable that the first diffusion layer 31 has a haze value of 5% or more and a total light transmittance of 60% or more. In this numerical range, when the haze value of the first diffusion layer 31 is less than 5%, the effect of diffusing and reflecting the incident light to the first diffusion layer 31 to the second region 3 and the third region 3 is sufficient. This is because if the total light transmittance of the first diffusion layer 31 is less than 60%, the light passing through the first region 1 is reduced, so that the luminance is lowered.
The first diffusion layer 31 has an effect of reducing glare due to reflected light on the surface of the support 8 when the first region 1 is observed when the light source 6 is not lit. At the same time, since the light is transmissive, the visual recognition of indirect light in the first region 1 when the light source 6 is turned on is not hindered.
The first diffusion layer 31 is not necessarily provided, and it is not necessary to provide the first diffusion layer 31 unless there is a need for reduction of reflected light on the surface of the support 8 and design.

A fourth decorative layer 17 is provided on a part of the first region 1 on the surface of the first diffusion layer 31 (the support 8 when there is no first diffusion layer 31) on the viewer 6 side.
In FIG. 1A, the decorative layer 13 is displayed on the same stage as the first decorative layer in order to make the order and type of the layers easy to understand, but in reality, the diffusion layer is as shown in FIG. 31 are stacked on the surface of the viewer 6 side.
The fourth decorative layer 17 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.
Although it is desirable to use black ink for the 4th decoration layer 17, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
In addition, the total light transmittance of the fourth decorative layer 17 is desirably 20% or less.
When the total light transmittance of the 4th decoration layer 17 is larger than 20%, the transmitted light of the 4th decoration layer 17 is visually recognized, and the part which does not have the 4th decoration layer 17 in a 1st area | region This is because there is an adverse effect that the contrast of the fourth decorative layer 17 decreases and the visibility of the fourth decorative layer 17 decreases.
When the light source is turned on, indirect light spreads in the first region 1, but since there is the fourth decorative layer 17 in a part of the first region 1, that portion is shielded and visually recognized as a pattern. . The fourth decorative layer 17 can be provided if necessary in terms of design, and even if the fourth decorative layer 17 is not provided, other functions in the information display panel 5 are not affected.

The second diffusion layer 32 is disposed in the second region 2 and the third region 3 on the surface of the support 8 on the viewer 6 side.
The second diffusion layer 32 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.
Although it is desirable to use a transparent ink for the second diffusion layer 32, it is not limited to the transparent ink as long as it has a light diffusion effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a diffusion effect will come out easily.
The haze value of the second diffusion layer 32 is preferably 5% or more, and the total light transmittance is preferably 60% or more and 98% or less. In this numerical range, when the haze value of the second diffusion layer 32 is less than 5%, the effect of diffusing and reflecting incident light to the second diffusion layer 32 to the first region 1 cannot be sufficiently obtained. When the total light transmittance of the second diffusing layer 32 is less than 60%, the amount of light incident on the second reflecting layer 11 and the third reflecting layer 13 is reduced, so that the reflected light to the first region 1 is reduced. This is because the three-dimensional effect is impaired due to a decrease in luminance.
The second diffusion layer 32 diffuses part of the light incident from the support 8 when the light source 6 is turned on and emits the light to the first region 1, thereby increasing the brightness of the indirect light in the first region 1. There is an effect of improving the stereoscopic effect at the boundary between the first region 1 and the second region 2 and at the boundary between the first region 1 and the third region 3.
The second diffusion layer 32 is not necessarily provided, and can be provided when the luminance in the first region 1 needs to be improved.

The second reflective layer 11 is arranged in the second region 2 of the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side.
The second reflective layer 11 has an effect that the incident light is diffusely reflected with a predetermined probability.
The second reflective layer 11 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.
Although it is desirable to use white ink for the second reflective layer 11, it is not limited to white ink as long as it has a light reflection effect and transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, it is desirable that the reflectance of light of 380 to 780 nm in the second reflective layer 11 is 60% or more, and the total light transmittance of the second reflective layer 11 is 5% or more and 40% or less.
When the reflectance of the second reflective layer 11 is less than 60%, the brightness of the indirect light reflected by the second reflective layer 11 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired. Further, when the total light transmittance of the second reflective layer 11 is less than 5%, when the first decorative layer 12 is provided with an opening having a design shape such as a character, the luminance of the portion is low, and the character This is because the iso-design shape is not visually recognized. On the other hand, if the total light transmittance is 40% or more, the reflectance is lowered, and as described above, the stereoscopic effect at the boundary between the first region and the second region is lowered due to the luminance reduction of the indirect light. is there.
When the light source 6 is turned on, the light reflected by the second reflective layer 11 is visually recognized as indirect light in the first region 1. At this time, the larger the width of the second reflective layer 11 in the second region 2, the higher the luminance because there is more light diffusely reflected toward the first region 1, and the first region 1 and the first region 1 The stereoscopic effect at the boundary between the two regions 2 is increased. Moreover, when providing design shapes, such as a character, in the 2nd area | region 2 on design, the opening of the 1st decorating layer 12 which the light which permeate | transmitted the opening part of the 2nd reflective layer 11 or the 2nd reflective layer 11 mentions later. By passing through the part, the design shape such as letters is visually recognized as direct light from the observer.

A first decorative layer 12 is laminated on the surface of the second reflective layer 11 on the viewer 7 side. The first decorative layer 12 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. Although it is desirable to use black ink for the 1st decoration layer 6, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
Moreover, it is desirable that the total light transmittance of the first decorative layer 12 is substantially constant within a range of 20% or less.
When the total light transmittance is larger than 20%, the transmitted light of the second reflective layer 11 in the second region 2 cannot be blocked, and the contrast between the first region 1 and the second region 2 is lowered. This is because the three-dimensional effect is impaired.
The first decorative layer 12 represents a pattern in the second region 2 and shields light from the light source 6 that passes through the second reflective layer 11. Further, when a design shape such as a character is provided in the second region 2, an opening of the design shape such as a character is provided in the first decorative layer 12, and the light transmitted through the second reflective layer 11 is the first By passing through the opening of the decorative layer 12, the design shape such as letters is visually recognized as direct light by an observer.

The third reflective layer 13 having an opening in the third region 3 is disposed on the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side. .
The third reflective layer 13 has the effect of diffusely reflecting incident light with a predetermined probability.
The third reflective layer 13 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.
Although it is desirable to use white ink for the third reflective layer 13, it is not limited to white ink as long as it has a light reflection effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, it is desirable that the reflectance of light of 380 to 780 nm in the third reflective layer 13 is 60% or more.
When the reflectance of the third reflective layer 13 is less than 60%, the luminance of the indirect light reflected by the third reflective layer 13 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired.
When the light source 6 is turned on, the light reflected by the third reflective layer 13 is provided in the first region on the light source side surface of the support 8 and the third region 3. The light is incident on the fourth reflective layer 22 provided on the surface. Among these, those in the first region 1 are visually recognized as indirect light, and those in the third region 3 pass through the openings of the third reflective layer 13 and the second light shielding layer 14 and the second decorative layer 15. And is visible to the observer through the transparent decorative layer 16.
At this time, when the area of the third reflective layer 13 excluding the opening is larger, more light is reflected by the third reflective layer 13 and observed as indirect light in the first region. And the three-dimensional effect at the boundary of the third region 3 is increased.

A second light shielding layer 14 is laminated on the surface of the third reflective layer 13 on the viewer 7 side.
The second light shielding layer 14 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.
Although it is desirable to use black ink for the 2nd light shielding layer 14, if it has a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
The total light transmittance of the second light shielding layer 14 is desirably 20% or less. When the total light transmittance of the second light shielding layer 14 is larger than 20%, the light transmitted through the third reflective layer 13 is directly recognized, and the light transmitted through the opening of the second light shielding layer 14 This is because the contrast is lowered and the picture seen through the second decorative layer 15 and the transparent decorative layer 16 cannot be displayed beautifully.
When the light source 6 is turned on, the light that has entered the third reflective layer 13 from the second diffusion layer 32 is substantially reflected and absorbed by the third reflective layer 13, but the light that has not been reflected is second The light enters the light shielding layer 14. The second light-shielding layer 14 shields the light, thereby increasing the contrast of the boundary between the indirect light of the first region 1 and the third region 3 to give a stereoscopic effect. The pattern of the third region can be expressed by calculating the luminance difference between the light that passes through the opening and passes through the second decorative layer 15 and the transparent decorative layer 16.

Of the surface on the viewer 6 side of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32), the surface corresponding to the opening of the third reflective layer 13, and the second light shielding layer The 14th decorating layer 15 laminated | stacked on the surface at the side of 14 observers 6 is arrange | positioned over the 3rd area | region whole region.
The second decorative layer 15 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.
Although it is desirable to use a gray ink for the 2nd decoration layer 15, if it is translucent, it will not restrict to a gray ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, semi-permeable property will come out easily.
The total light transmittance of the second decorative layer 15 is preferably 4% or more and 40% or less.
When the total light transmittance of the second decorative layer 15 is less than 4%, the light passing through the opening of the second light shielding layer 14 cannot be visually recognized, and the design of the third region 3 cannot be visually recognized when the light source is turned on. This is because there are harmful effects. On the other hand, when the total light transmittance of the second decorative layer 15 is greater than 40%, the opening 14 of the second light shielding layer 14 cannot be concealed when the light source is not turned on, and is not turned on when the light source is turned on. This is because there is an adverse effect that the difference in the pattern of the third region 3 at the time cannot be expressed.
The second decorative layer 15 conceals the third reflective layer 13 and the second light-shielding layer 14 and the opening when the light source 6 is not lit. It is visually recognized as being composed only of the decorative layer 15 and the transparent decorative layer 16. On the other hand, when the light source 6 is turned on, the second decorative layer 15 transmits light that passes through the openings of the third reflective layer 13 and the second light shielding layer 14 and enters the transparent decorative layer 16 to thereby prevent non-reflection. It is possible to express a beautiful design that is different from the lighting.

The transparent decorative layer 16 is laminated at a position substantially corresponding to the opening of the third reflective layer 13 on the surface of the second decorative layer 15 on the viewer 6 side.
The transparent decorative layer 16 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.
Although it is desirable to use a transparent ink for the transparent decoration layer 16, if it has a light transmittance, it will not be restricted to a transparent ink. Although there is no restriction | limiting in thickness, if it is 5 micrometers-30 micrometers, it will be easy to visually recognize from an observer.
Further, the total light transmittance of the transparent decorative layer 16 is desirably 80% or more.
This is because when the total light transmittance of the transparent decorative layer 16 is less than 80%, the luminance of the third region 3 when the light source is turned on is lowered, which hinders visual recognition.
The transparent decorative layer 16 is observed as a pattern on the surface of the second decorative layer 15 when the light source 6 is not lit, and the third reflective layer 13 and the second light shielding layer 14 are observed when the light source 6 is lit. The light passing through the opening and passing through the second decorative layer 15 is transmitted and observed as a pattern.
The transparent decorative layer 16 can be provided if necessary in terms of design. Even if the transparent decorative layer 16 is not provided, other functions in the information display panel 5 are not affected.

Next, the laminated structure on the light source 6 side of the support 8 will be described in detail.
The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side. In addition, the fourth reflective layer 22 is arranged at a position corresponding to the opening of the third reflective layer 13 in the third region 3 on the surface of the support 8 on the light source 6 side.
The first reflective layer 21 and the fourth reflective layer 22 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.
Although it is desirable to use white ink for the first reflective layer 21 and the fourth reflective layer 22, it is not limited to white ink as long as it has a light reflection effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Moreover, it is desirable that the reflectance of light of 380 to 780 nm in the first reflective layer 21 and the fourth reflective layer 22 is 20% or more.
When the reflectivity in the first reflective layer 21 and the fourth reflective layer 22 is less than 20%, the brightness of the indirect light reflected by the first reflective layer 21 and the fourth reflective layer 22 decreases. This is because the three-dimensional effect is impaired.
When the light source 6 is turned on, the light reflected by the second reflective layer 11 and the third reflective layer 13 and the light diffused by the support 8 and the second diffusion layer 32 are incident on the first reflective layer 21. Reflected and viewed as indirect light from the observer. Thereby, there is an effect of giving a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.

The first light shielding layer 23 is laminated on the light source side surfaces of the first reflective layer 21 and the fourth reflective layer 22.
The first light shielding layer 23 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.
Although it is desirable to use black ink for the first light shielding layer 23, it is not limited to black ink as long as it has a light shielding effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
The total light transmittance of the first light shielding layer 23 is desirably 20% or less. When the total light transmittance of the first light-shielding layer 23 is greater than 20%, the incident light of the first light-shielding layer 23 cannot be shielded, and the direct light is visually recognized at the openings of the first region and the third reflective layer. This is because the indirect light visibility is lowered and the stereoscopic effect is impaired.
When the light source 6 is turned on, direct light traveling toward the first reflective layer 21 is blocked by the first light blocking layer 23. Thereby, since there is no light incident on and transmitted through the first reflective layer 21 from the other surface side, the visibility of indirect light in the first region 1 is increased, and the first region 1 and the second region 2 are increased. And the three-dimensional effect at the boundary between the first region 1 and the third region 3.

Of the surface of the support 8 on the light source 6 side, the light-transmitting colored layer 24 is provided on the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided. In particular, the surface is not limited to the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided, and may be stacked on the surface of the second light shielding layer 23 on the light source 6 side.
The light transmissive colored layer 24 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.
It is desirable to use a light-transmitting chromatic ink for the light-transmitting colored layer 24, but the present invention is not limited to this as long as a light-transmitting chromatic color layer can be provided.
Further, the light transmissive colored layer 24 preferably has a total light transmittance of 20% or more. When the total light transmittance of the light-transmitting colored layer 24 is less than 20%, the luminance of the indirect light that is incident on and reflected by the second reflective layer 11 and the third reflective layer 13 is visually recognized. This is because there is a negative effect that the stereoscopic effect is impaired due to the lowering.
When the light source 6 is turned on, the light transmitted through the light-transmissive colored layer 24 is reflected by the second reflective layer 11 and the third reflective layer 13 and further diffused by the support 8 and the second diffusion layer 32. Indirect light depends on the color of the light-transmitting colored layer 24 because it is reflected after being incident on the first reflective layer 21 and is visually recognized as indirect light by an observer. By making the light-transmitting colored layer 24 an arbitrary color, characters, designs, etc. are displayed beautifully.

Further, when a design shape such as a character is provided in the second region 2, an opening can be provided in a region slightly larger than a portion corresponding to the design shape such as a character of the light-transmitting colored layer 24. When the light-transmitting colored layer 24 is provided with an opening, direct light does not pass through the light-transmitting colored layer 24 when the light source 6 is turned on. Therefore, the design shape such as letters from the observer depends on the second reflective layer. Visible as direct light. Here, the reason why the opening of the light-transmitting colored layer 24 is slightly larger than the design shape of characters and the like is to prevent the light transmitted through the light-transmitting coloring layer 9 from interfering with the end portions of the design shapes of characters and the like. is there.
Specifically, the opening of the light-transmitting colored layer 24 has an outer periphery of 0.050 mm or more from the outer periphery of the opening of the first decorative layer 12, and the opening of the light-transmitting colored layer 24 is It is desirable that the outer periphery is separated from the boundary between the second region 2 and the first region 1 by 1.000 mm or more.
When the opening of the light transmissive colored layer 24 is not more than 0.050 mm outside from the outer periphery of the opening of the first decorative layer 12, the light visible from the opening of the first decorative layer 12 is white. This is because there is an adverse effect that the light is visually recognized as chromatic light that has passed through the light-transmitting colored layer 24 instead of light. In addition, it is not this limitation when the light visually recognized from the opening part of the 1st decoration layer 12 may be chromatic color on a design.
Further, when the outer periphery of the opening of the light transmissive colored layer 24 is not separated from the boundary between the second region and the first region by 1.000 mm or more, the second reflective layer is separated from the opening of the light transmissive colored layer 24. This is because the indirect light incident on the first region and reflected by the first region is not chromatic.
This opening is not necessarily provided. If the design shape such as letters when the light source is turned on needs to depend on the color of the light-transmitting colored layer 24, it is not necessary to provide the opening. Absent.

Light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the second region 2 and the fourth reflection layer 22, and the second reflection layer 11 and the third reflection layer 32. The light enters the reflective layer 13. At this time, if the support 8 includes a diffusion layer, part of the light transmitted through the support 8 is diffused and enters the first reflection layer 21 and the fourth reflection layer 22. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21 and the fourth reflection layer 22. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21 and the fourth reflective layer 22. The light incident on the first reflective layer 21 and the fourth reflective layer 22 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.
The reflected light of the fourth reflective layer 22 described above passes through the openings of the third reflective layer 13 and the second light shielding layer 14 and passes through the second decorative layer 15 and the transparent decorative layer 16 for observation. It is visually recognized by the person 7. Since the direct light from the light source 6 is shielded by the first light shielding layer 23 and the second light shielding layer 14, the pattern of the third region 3 is expressed by this light and dark.

A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 4.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 2, the observer 7 views from one surface side of the light-transmissive support 8, and the light source 6 is installed on the other surface side of the support 8.

A first diffusion layer 31 and a fourth decorative layer 17 are sequentially stacked in the first region 1 on the surface of the support 8 on the viewer 6 side.
In addition, the second diffusion layer 32, the second reflection layer 11, and the second decoration layer 12 are sequentially laminated in the second region 2 on the surface of the support 8 on the viewer 6 side.
Further, the second diffusion layer 32, the third reflective layer 13, the second light shielding layer 14, the second decorative layer 15, in the third region 3 of the surface of the support 8 on the viewer 6 side, The transparent decoration layer 16 is laminated | stacked in order.
A first reflective layer 21, a light-transmitting colored layer 24, and a first light-shielding layer 23 are sequentially laminated in the first region 1 on the surface of the support 8 on the light source 6 side.
Further, a light transmissive colored layer 24 is provided in the second region 2 of the surface of the support 8 on the light source 6 side.
Further, a fourth reflective layer 22, a light-transmitting colored layer 24, and a first light-shielding layer 23 are sequentially laminated on the third region 3 in the surface of the support 8 on the light source 6 side.

  The structure, material, production method, and effect of the support 8 are the same as those in the first embodiment.

  The laminated structure of the support 8 on the viewer 7 side is the same as that in the first embodiment.

The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side. In addition, the fourth reflective layer 22 is arranged at a position corresponding to the opening of the third reflective layer 13 in the third region 3 on the surface of the support 8 on the light source 6 side.
The materials, production methods, and effects of the first reflective layer 21 and the fourth reflective layer 22 are the same as those in the first embodiment described above.

Of the surface of the support 8 on the light source 6 side, the light-transmitting colored layer 24 is provided on the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided. In particular, the surface is not limited to the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided, and is also laminated on the surface of the first reflective layer 21 and the fourth reflective layer 22 on the light source 6 side. It does not matter.
The material, production method, and effects of the light transmissive colored layer 24 are the same as those of the first embodiment described above.

After the light transmissive colored layer 24 is disposed, the first light shielding layer 23 is laminated at a position corresponding to the first reflective layer 21 and the fourth reflective layer 22.
The material, production method, and effect of the first light shielding layer 23 are the same as those in the first embodiment described above.

The light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4 through the opening of the first light shielding layer 23. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the second region 2 and the fourth reflection layer 22, and the second reflection layer 11 and the third reflection layer 32. The light enters the reflective layer 13. At this time, if the support 8 includes a diffusion layer, part of the light transmitted through the support 8 is diffused and enters the first reflection layer 21 and the fourth reflection layer 22. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21 and the fourth reflection layer 22. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21 and the fourth reflective layer 22. The light incident on the first reflective layer 21 and the fourth reflective layer 22 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.
The reflected light of the fourth reflective layer 22 described above passes through the openings of the third reflective layer 13 and the second light shielding layer 14 and passes through the second decorative layer 15 and the transparent decorative layer 16 for observation. It is visually recognized by the person 7. Since the direct light from the light source 6 is shielded by the first light shielding layer 23 and the second light shielding layer 14, the pattern of the third region 3 is expressed by this light and dark.

FIG. 3 is a cross-sectional view of the laminated sheet 4 for the information display panel 5 according to the third embodiment of the present invention, taken along a plane perpendicular to the sheet extending direction. (A) shows each layer separated for easy understanding of the order of lamination, and (B) shows a state in which the layers are actually laminated.
As shown in FIG. 3, the laminated sheet 4 includes a first region 1, a second region 2, and a third region that are adjacent to the first region 1 and separated from each other as viewed from the thickness direction of the sheet. Divided into three.
A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 4.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 3, the observer 7 views from one surface side of the light-transmissive support 8, and the light source 6 is installed on the other surface side of the support 8.

A first diffusion layer 31 and a fourth decorative layer 17 are sequentially stacked in the first region 1 on the surface of the support 8 on the viewer 6 side.
In addition, the second diffusion layer 32, the second reflection layer 11, and the second decoration layer 12 are sequentially laminated in the second region 2 on the surface of the support 8 on the viewer 6 side.
Further, in the third region 3 of the surface of the support 8 on the viewer 6 side, the second diffusion layer 32, the third reflection layer 13, the second decoration layer 15, the second light shielding layer 14, The transparent decoration layer 16 is laminated | stacked in order.

A first reflective layer 21, a first light-shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated in the first region 1 on the surface of the support 8 on the light source 6 side.
Further, a light-transmitting colored layer 24 is provided in the second region 2 and the third region of the surface of the support 8 on the light source 6 side.

  The structure, material, production method, and effect of the support 8 are the same as those in the first embodiment.

  Further, in the laminated structure on the viewer 7 side of the support 8, the structures of the first region and the second region are the same as those in the first embodiment described above.

The second diffusion layer 32 is disposed in the third region 3 on the surface of the support 8 on the viewer 6 side.
The material and production method of the second diffusion layer 32 are the same as those in the first embodiment described above.

The third reflective layer 13 is disposed over the entire third region 3 of the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side.
The material and production method of the third reflective layer 13 are the same as in the case of the first embodiment described above.
Here, the reflectance of light of 380 to 780 nm in the third reflective layer 13 is preferably 60% or more, and the total light transmittance of the third reflective layer 13 is desirably 5% or more and 40% or less.
When the reflectance of the third reflective layer 13 is less than 60%, the luminance of the indirect light reflected by the third reflective layer 13 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired. Further, when the total light transmittance of the third reflective layer 13 is less than 5%, the luminance of light that is visible through the transparent decorative layer 16 through the opening of the second light shielding layer 14 is lowered. This is because the pattern of the third region 3 cannot be displayed beautifully.
On the other hand, if the total light transmittance is 40% or more, the reflectance is lowered, and as described above, the stereoscopic effect at the boundary between the first region and the second region is lowered due to the luminance reduction of the indirect light. is there.
When the light source 6 is turned on, the light reflected by the third reflective layer 13 enters the first reflective layer 21 in the first region 1 and is visually recognized by the observer 7 as indirect light. At this time, the larger the width of the third reflective layer 13 is, the more light is reflected by the third reflective layer 13 and observed as indirect light in the first region, and the first region 1 and the third region The stereoscopic effect at the boundary of 3 increases.

A second decorative layer 15 is laminated on the surface of the third reflective layer 13 on the viewer 6 side.
The material of the 2nd decoration layer 15 and the preparation method are the same as that of the case of 1st Embodiment mentioned above.
When the light source 6 is not turned on, external light is reflected by the second decorative layer 15 through the openings of the transparent decorative layer 16 and the second light shielding layer 14, and the second decorative layer 15 is viewed from the observer 7. The color of is visible.
On the other hand, when the light source 6 is turned on, the second decorative layer 15 is semi-transmissive at the opening of the second light shielding layer 14 on which the transparent decorative layer 16 is laminated. The chromatic color light is observed, and a beautiful design characteristic different from that when the lamp is not lit can be expressed. Without the second decorative layer 15, the chromatic color of the light-transmitting colored layer 24 can be seen through the third reflective layer 13 when the light source 6 is not lit. I can't express it.

A second light shielding layer 14 having an opening is laminated on the surface of the second decorative layer 15 on the viewer 7 side.
The material and production method of the second light shielding layer 14 are the same as those in the first embodiment described above.
When the light source 6 is turned on, the light transmitted through the second decorative layer 15 is shielded to represent the pattern in the third region 3. Furthermore, since the light is shielded at the boundary with the first region 1, the contrast with the indirect light visually recognized in the first region 1 can be increased to enhance the stereoscopic effect.

A transparent decorative layer 16 is laminated at a position corresponding to the opening of the third reflective layer 13 after the second light shielding layer 14 is disposed.
The material and production method of the transparent decorative layer 16 are the same as in the case of the first embodiment described above.
The transparent decorative layer 16 is observed as a pattern on the outermost surface of the third region 3 when the light source 6 is not lit, and transmits light passing through the opening of the third reflective layer 13 when the light source 6 is lit. The third reflective layer 13 is visually recognized by the observer as a picture.
The transparent decorative layer 16 can be provided if necessary in terms of design. Even if the transparent decorative layer 16 is not provided, other functions in the information display panel 5 are not affected.

The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side.
The material, production method, and effects of the first reflective layer 21 are the same as those in the first embodiment described above.

A first light shielding layer 23 is laminated on the surface of the first reflective layer 21 on the light source 6 side.
The material, production method, and effect of the first light shielding layer 23 are the same as those in the case of FIG.

The light-transmitting colored layer 24 is provided in the second region and the third region of the surface of the support 8 on the light source 6 side. In particular, the second region and the third region are not limited, and may be stacked on the first light shielding layer 23.
The material, production method, and effects of the light transmissive colored layer 24 are the same as those in the case of FIG.

Light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the first light-shielding layer 23 and the first reflection layer 21, and the second reflection layer 11 and the third reflection layer 32. Is incident on the reflective layer 13. At this time, if the support 8 includes a diffusion layer, a part of the transmitted light of the support 8 is diffused and enters the first reflection layer 21. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21. The light incident on the first reflective layer 21 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.
Further, in the third region 3, a part of the direct light transmitted through the third reflective layer 13 and the second decorative layer 15 passes through the opening of the second light shielding layer 14 and is transmitted through the transparent decorative layer 16. And it is visually recognized as a beautiful pattern.

Light from the light source 6 enters the light transmissive colored layer 24 from the incident surface of the sheet 4 through the opening of the first light shielding layer 23. The light that has passed through the light-transmitting colored layer 24 enters the second reflective layer 11 and the third reflective layer 13 through the support 8 and the second diffusion layer 32 from the opening of the first reflective layer 21. . At this time, if the support 8 includes a diffusion layer, a part of the transmitted light of the support 8 is diffused and enters the first reflection layer 21. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21.

A first embodiment of the present invention will be specifically described along the configuration of FIG.
A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1. The decorative layer 17 is laminated, the second diffusion layer 32 of transparent ink is provided in the second region 2 and the third region 3, and the second reflective layer 11 of white ink is the second of the second region 2. The first decorative layer 12 of black ink is laminated on the second reflective layer 11, and the third reflective layer 13 of white ink having an opening is formed in the third region 3. Laminated on the second diffusion layer 32, the black ink second light shielding layer 14 is laminated on the third reflective layer 13, and the gray ink second decorative layer 15 is formed on the second light shielding layer 14. After the arrangement, the transparent decorative layer 16 of the transparent ink is arranged in substantially the entire area of the third region 3. Opening of the reflective layer 13 of 3 stacked in a position substantially corresponding to the.
The first reflective layer 21 of white ink is provided in the first region 1 on the other surface side of the support 8, and the fourth reflective layer 22 of white ink is the third reflective layer in the third region 3. The first light-shielding layer 23 of black ink is laminated on the first reflective layer 21 and the fourth reflective layer 22, and the light-transmitting colored layer 24 of blue ink is provided in the first opening. After the light shielding layer 23 is provided, the first region 1, the second region 2, and the third region 3 are provided.
Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

  In Table 1, the thickness d of the support 8 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 40 mm, the aperture ratio p of the second light shielding layer 14 is 0.50, and the configuration of FIG. The calculation result of w2 / w1 when the width w1 of the widest portion of the region 1 of 1 and the width w2 of the narrowest portion of the second region 2 are changed, the color when the light source 6 is not lit, and the first when lit The color in the first region 1 and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w1 / w2 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

  In Table 2, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are shown in Table 2. The calculation result of k expressed by Expression (7) when the width w3 of the narrowest portion of the region 3 and the aperture ratio p of the second light shielding layer 14 are changed, the color when the light source 6 is not lit and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 3rd area | region 3 are shown.

  In Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Moreover, in order to obtain sufficient stereoscopic effect in the first region 1, it can be confirmed that the value of k represented by the formula (7) needs to be 0.15 or more. If k is less than 0.15, the area of the third reflective layer 13 is small, so that it is presumed that the luminance of the light that is diffusely reflected by the third reflective layer 13 and goes toward the first region 1 becomes low. .

  In Table 3, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 and the second in the configuration of FIG. When the aperture ratio p of the light shielding layer 14 is w2 / w1 is 1 and the value of k represented by the formula (7) is 1, the thickness d and w2 of the support 8 are changed. The calculated value of d × w2, the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  In Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

  In Table 4, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 in the configuration of FIG. The thickness d, w3 and p of the support 8 were changed when w2 / w1 was 1 and the value of k represented by the formula (7) was 1. The calculated value of h in Equation (8), the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the third region 3 Show. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 4, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that the value of h represented by the formula (8) needs to be 1.00 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If the value of h is less than 1.00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

A second embodiment of the present invention will be specifically described along the configuration of FIG.
A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1. The decorative layer 17 is laminated, the second diffusion layer 32 of transparent ink is provided in the second region 2 and the third region 3, and the second reflective layer 11 of white ink is the second of the second region 2.

Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 5, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w1 / w2 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

  2, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are set.

  From Table 6, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, the value of k represented by the above formula (7) needs to be 0.15 or more. If the value of k is less than 0.15, the area of the third reflective layer 13 is small, so it is assumed that the luminance of light that is diffusely reflected by the third reflective layer 13 and goes toward the first region 1 is lowered. Is done.

  In Table 7, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 and the second width in the configuration of FIG. When the aperture ratio p of the light shielding layer 14 is w2 / w1 is 1 and the value of k represented by the formula (7) is 1, the thickness d and w2 of the support 8 are changed. The calculated value of d × w2, the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 7, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

In the aperture ratio p of the light shielding layer 14, when w2 / w1 is 1, and the value of k in the formula (7) is 1, the thickness d of the support 8 and w3 and p are changed. The calculated value of h in the above equation (8), the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the third region 3 Show. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 8, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Moreover, in order to obtain sufficient stereoscopic effect in the first region 1, it can be confirmed that the value of h in the formula (8) needs to be 1.00 or more. If the value of h is less than 1.00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

Tables 1 to 4 of Example 1 and Tables 5 to 8 of Example 2 corresponding thereto correspond to the same results.
This is because the light-transmitting colored layer 24 is laminated after the first light-shielding layer 23 as shown in FIG. 1, or after the first reflective layer 21 as shown in FIG. It is considered that the effect is the same because it is arranged in the opening of 23.

A third embodiment of the present invention will be specifically described along the configuration of FIG.
A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1.

The second decorative layer 15 of gray ink is disposed on the third reflective layer 13 and is laminated on the layer 32, and the second light-shielding layer 14 of black ink having an opening is the second decorative layer 15. The transparent decorative layer 16 of transparent ink is laminated on the opening of the second light shielding layer 14 in the third region 3 after the second light shielding layer 14 is arranged.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 9, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

  From Table 10, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the width of the third reflective layer 13 is narrow, so that it is estimated that the brightness of the light that is diffusely reflected by the third reflective layer 13 and goes to the first region 1 is lowered. Is done.

Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 11, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low.

It can be confirmed that it is necessary to be over 00. d × w3 is 5 . If it is less than 00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the brightness of the light toward the first region 1 is assumed to be low.

The black ink first decorative layer 12 is laminated on the second reflective layer 11, and the white ink third reflective layer 13 is the second diffusion of the third region 3. The second decorative layer 15 of gray ink is disposed on the third reflective layer 13 and is laminated on the layer 32, and the second light-shielding layer 14 of black ink having an opening is the second decorative layer 15. The transparent decorative layer 16 of transparent ink is laminated on the opening of the second light shielding layer 14 in the third region 3 after the second light shielding layer 14 is arranged. It is laminated to a corresponding position.
After the first reflective layer 21 of white ink is provided in the first region 1 on the other surface side of the support 8 and the light-transmissive colored layer 24 of blue ink is provided with the first reflective layer 21 To the first region 1, the second region 2, and the third region 3, and after the first light-shielding layer 23 of black ink is provided with the light-transmitting colored layer 24, the first reflective layer is formed. Is laminated at a position corresponding to 21,
Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

  In Table 13, the thickness d of the support 8 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 40 mm, the width w1 of the widest portion of the first region 1 and the second The calculation result of w2 / w1 when the width w2 of the narrowest part of the region 2 is changed, the color when the light source 6 is not lit, the color in the first region 1 when lit, the first region 1 and the second region The stereoscopic effect of the boundary portion of the region 2 is shown.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 13, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

  In Table 14, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, the width w1 and the third width of the widest portion of the first region 1 are shown in Table 14. The calculation result of w3 / w1 when the width w3 of the narrowest part of the region 3 is changed, the color when the light source 6 is not lit, the color in the first region 1 when lit, the first region 1 and the third The stereoscopic effect of the boundary part of the area 3 is shown.

  From Table 14, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the width of the third reflective layer 13 is narrow, so that it is estimated that the brightness of the light that is diffusely reflected by the third reflective layer 13 and goes to the first region 1 is lowered. Is done.

  In the configuration shown in FIG. 4, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2 and the width w3 of the narrowest portion of the third region 3 in the configuration of FIG. When / w1 is 1 and w3 / w1 is 1, the calculated value of d × w2 when the thickness d and w2 of the support 8 are changed, the color when the light source 6 is not lit, and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 2nd area | region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 15, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

In the configuration shown in FIG. 4, in the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, and the width w3 of the narrowest portion of the third region 3, w2 When / w1 is 1 and w3 / w1 is 1, the values of d and w3 when the thicknesses d and w3 of the support 8 are changed, the color when the light source 6 is not lit and the first value when lit 1 shows the color in the first region 1 and the stereoscopic effect at the boundary between the first region 1 and the third region 3. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

In Table 16, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. In order to obtain a sufficient stereoscopic effect in the first region 1, d × w3 is 5 . It can be confirmed that it is necessary to be over 00. d × w3 is 5 . If it is less than 00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the brightness of the light toward the first region 1 is assumed to be low. The

  Tables 9 to 12 of Example 3 and Tables 13 to 16 of Example 4 corresponding thereto correspond to the same results. Even if the light-transmitting colored layer 24 is laminated after the first light-shielding layer 23 as shown in FIG. 3 or after the first reflective layer 21 as shown in FIG. It is considered that the effect is the same because it is arranged in the opening of 23.

  In the information display panel 5 using the sheet 4 of the above-described embodiment, the light source 6 is turned on to produce a three-dimensional effect in the first region 1 corresponding to characters, pictures and the like, and when the light source 6 is turned on and off. I was able to express the characters and designs beautifully by changing the color when the lamp was lit.

  The information display panels produced in Examples 1 to 4 were used for transportation equipment including a light source on the back and a resin cover on the front observer side.
