[First Embodiment]
With reference to FIG. 1 to FIG. 12, a first embodiment in which a display body and a display body observation method in the present invention are embodied will be described. Below, the structure of a display body, the observation method of a display body, and the manufacturing method of a display body are demonstrated in order.

[Configuration of the display body]
The configuration of the display body will be described with reference to FIGS.
As shown in FIG. 1, the display body 10 includes a base material 11, a reflective layer 12, an orientation regulation layer 13, a retardation layer 14, an adhesive layer 15, and a lens array layer 16.

  The retardation layer 14 includes a plurality of liquid crystal molecules and has light transmission properties. The phase difference layer 14 includes a plurality of first phase difference portions 14a arranged at a phase difference pitch that is a predetermined interval, and a second phase difference portion 14b that fills the space between the plurality of first phase difference portions 14a. The alignment direction of the liquid crystal molecules in the first retardation portion 14a is the first alignment direction, the alignment direction of the liquid crystal molecules in the second retardation portion 14b is the second alignment direction, and the first alignment direction and the second alignment direction are Are different from each other.

  The alignment regulation layer 13 has light transmittance and is in contact with the retardation layer 14. The orientation regulating layer 13 includes a plurality of first regulating portions 13a that overlap one by one with each first retardation portion 14a in the direction in which the retardation layer 14 and the orientation regulating layer 13 are stacked. Each first restricting portion 13a has a characteristic of restricting the alignment direction of the liquid crystal molecules included in the first phase difference portion 14a overlapping the first restricting portion 13a. The alignment regulating layer 13 includes photoreactive molecules that exhibit characteristics of regulating the alignment direction of liquid crystal molecules by light irradiation.

  The alignment restriction layer 13 includes a second restriction portion 13b that overlaps the second retardation portion 14b in the direction in which the retardation layer 14 and the alignment restriction layer 13 are stacked. The second restricting portion 13b has a characteristic of restricting the alignment direction of the liquid crystal molecules included in the second retardation portion 14b.

That is, the orientation restriction layer 13 includes a plurality of first restriction parts 13a and a second restriction part 13b filling between the plurality of first restriction parts 13a. In the direction in which the orientation regulating layer 13 and the retardation layer 14 are stacked, each first regulating portion 13a overlaps with the first retardation portion 14a different from all the other first regulating portions 13a, and the second regulating portion 13b It overlaps with the second phase difference portion 14b.
The reflective layer 12 is opposed to and in contact with the orientation regulation layer 13 among the retardation layer 14 and the orientation regulation layer 13.

  The lens array layer 16 is opposed to the reflective layer 12 with the retardation layer 14 and the orientation regulating layer 13 interposed therebetween, and the lens array layer 16 is the retardation layer of the retardation layer 14 and the orientation regulating layer 13. 14 is opposed. The lens array layer 16 includes a plurality of lenses 16a arranged at a lens pitch different from the above-described phase difference pitch, and each lens 16a has a focus on the first phase difference portion 14a different from all the other lenses 16a. ing. The lens array layer 16 forms a stereoscopic image by a set of magnified images of the first phase difference portion 14a.

  The lens array layer 16 includes one support layer 16b having light transmittance, and a plurality of lenses 16a are arranged on the surface of the support layer 16b opposite to the surface facing the retardation layer 14. Each lens 16a is a convex microlens.

  According to such a display body 10, the latent image included as the first retardation portion 14 a in the retardation layer 14 appears as a three-dimensional image when a polarizer as a verifier is held over the display body 10. The visual effect of the display body 10 is enhanced.

  The adhesive layer 15 is located between the retardation layer 14 and the lens array layer 16 and has light transmittance. The adhesive layer 15 is in contact with the retardation layer 14 and the lens array layer 16 and adheres the retardation layer 14 and the lens array layer 16.

  Since the adhesive force between the liquid crystal molecules contained in the retardation layer 14 and the adhesive layer 15 is larger than the adhesive force between the photoreactive molecules contained in the alignment control layer 13 and the adhesive layer 15, the lens array layer Compared with the configuration in which 16 faces the orientation regulating layer 13, the lens array layer 16 and the layer facing the lens array layer 16 are more firmly bonded.

  The substrate 11 is located on the opposite side of the reflective layer 12 from the lens array layer 16 and is in contact with the reflective layer 12. In the display body 10, since the reflective layer 12 is located between the base material 11 and the orientation regulating layer 13, the degree of freedom in the method of forming the base material 11 is increased.

In FIG. 2, a part of the alignment control layer 13 and a part of the retardation layer 14 are shown enlarged.
As shown in FIG. 2, in the orientation regulation layer 13, the surface in contact with the retardation layer 14 is the surface, and an arbitrary direction parallel to the surface of the orientation regulation layer 13 is the X direction. In addition, an arbitrary direction parallel to the surface of the orientation regulating layer 13 and a direction orthogonal to the X direction is the Y direction.

  As described above, the alignment regulating layer 13 has the property of aligning the liquid crystal molecules contained in the retardation layer 14. In the alignment regulating layer 13, the direction that regulates the alignment of liquid crystal molecules, and the direction parallel to the surface of the alignment regulating layer 13 is the alignment regulating direction. In the first restricting portion 13a, the direction restricting the orientation of the liquid crystal molecules contained in the retardation layer 14 is the first restricting direction Dr1, and in the second restricting portion 13b, the orientation of the liquid crystal molecules contained in the retardation layer 14 is adjusted. The restricting direction is the second restricting direction Dr2. The angle formed by the X direction and the first restriction direction Dr1 is the first restriction angle θr1, the angle formed by the X direction and the second restriction direction Dr2 is the second restriction angle θr2, and the first restriction angle θr1. The second restriction angle θr2 is preferably different by 10 ° or more.

  Each of the first restricting portion 13a and the second restricting portion 13b may include a portion where the difference between the first restricting angle θr1 and the second restricting angle θr2 is smaller than 10 °. However, each of the first restricting portion 13a and the second restricting portion 13b may include a portion where the difference between the first restricting angle θr1 and the second restricting angle θr2 is 10 ° or more is 50% or more. preferable.

  In the retardation layer 14, the surface opposite to the surface in contact with the alignment regulating layer 13 is the surface, the direction parallel to the surface of the retardation layer 14, and the alignment direction of the liquid crystal molecules is the alignment direction. In the retardation layer 14, in the first retardation portion 14a, the alignment direction of the liquid crystal molecules is the first alignment direction Do1, and in the second retardation portion 14b, the alignment direction of the liquid crystal molecules is the second alignment direction Do2. . The first alignment direction Do1 is substantially equal to the first restriction direction Dr1, and the second alignment direction Do2 is substantially equal to the second restriction direction Dr2.

  The angle formed by the X direction and the first alignment direction Do1 is the first alignment angle θo1, and the angle formed by the X direction and the second alignment direction Do2 is the second alignment angle θo2. The first orientation angle θo1 is substantially equal to the first restriction angle θr1, and the second orientation angle θo2 is substantially equal to the second restriction angle θr2.

  Thus, in the retardation layer 14, the first orientation angle θo1 in the first retardation portion 14a and the second orientation angle θo2 in the second retardation portion 14b are different from each other. Therefore, the angle formed between the polarization axis of the polarized light incident on the retardation layer 14 and the X direction is a predetermined size, and the polarized light incident on the retardation layer 14 is transmitted through the first retardation portion 14a. The first phase difference portion 14a as a latent image is visualized. In addition, the angle formed between the polarization axis of polarized light incident on the retardation layer 14 and the X direction is a predetermined size, and the polarized light incident on the retardation layer 14 is transmitted through the second retardation portion 14b. Even when the angle is such that the first phase difference portion 14a is visible.

  The first retardation portion 14a has a star shape in a plan view opposite to the surface of the orientation regulating layer 13, but may have other shapes such as a circular shape, a polygonal shape, and a linear shape. . Or the 1st phase difference part 14a may have a shape expressing a predetermined character and number.

  FIG. 3 shows a part of the planar structure of the retardation layer 14 as viewed from the direction in which the lens array layer 16 and the retardation layer 14 are stacked. In FIG. 3, for convenience of explanation, the lens 16 a that overlaps the retardation layer 14 is indicated by a two-dot chain line.

  As shown in FIG. 3, in the phase difference layer 14, the plurality of first phase difference portions 14 a are arranged at a phase difference pitch Pd that is a predetermined interval along the X direction, and also the phase difference pitch along the Y direction. They are lined with Pd.

  In the lens array layer 16, the plurality of lenses 16a are arranged at a lens pitch Pl that is a predetermined interval along the X direction, and are also arranged at the same lens pitch Pl along the Y direction. As described above, the lens pitch Pl is a value different from the phase difference pitch Pd, and each lens 16a includes a plurality of first phase difference units as viewed from the direction in which the lens array layer 16 and the phase difference layer 14 overlap. 14a, the first phase difference portion 14a is different from the first phase difference portion 14a where all other lenses 16a overlap.

  The phase difference pitch Pd may be larger or smaller than the lens pitch Pl. A stereoscopic image having different visual effects can be obtained when the phase difference pitch Pd is larger than the lens pitch Pl and when the phase difference pitch Pd is smaller than the lens pitch Pl.

The phase difference pitch Pd and the lens pitch Pl preferably satisfy the following formula 1.
Pl = Pd ± Pd × 0.3 (Formula 1)

Further, when the phase difference pitch Pd and the lens pitch Pl satisfy the following Expression 2 or Expression 3, it is difficult to obtain a moire effect by the plurality of first phase difference portions 14a and the plurality of lenses 16a. The three-dimensionality of the three-dimensional image displayed by the display body 10 is lowered.
Pl> Pd × 1.3 (Formula 2)
Pl <Pd × 0.7 (Formula 3)

  As described above, although the value is different from the phase difference pitch Pd, the plurality of lenses 16a arranged at the lens pitch Pl substantially equal to the phase difference pitch Pd is compared with the plurality of first phase differences 14a arranged at the phase difference pitch Pd. By overlapping, the shape of the first phase difference portion 14a appears as a stereoscopic image.

  The lens pitch Pl is preferably 10 μm or more and 300 μm or less, and more preferably 20 μm or more and 200 μm or less. When the lens pitch Pl is 300 μm or less, the resolution of the image displayed on the display body 10 can be suppressed from being reduced, and the moire effect can be suppressed from being lowered. Further, when the lens pitch Pl is 10 μm or more, it becomes easy to form the first phase difference portions 14a arranged with the phase difference pitch Pd of the same degree as the lens pitch Pl, and it becomes easy to obtain a stereoscopic image of the first phase difference portions 14a. .

[How to observe the display]
A method of observing the display body will be described with reference to FIGS.
As shown in FIG. 4, when observing the display body 10, the polarizer P is held over the display body 10 in an environment that is not a dark room, in other words, an environment in which not less than visible light is incident. That is, the polarizer P is disposed between the display body 10 and the observer OB so that the lens array layer 16 of the display body 10 and the polarizer P face each other.

  At this time, the light passing through the polarizer P enters the display body 10 from the lens array layer 16. At least a part of the incident light is reflected by the reflection layer 12, and the reflected light is emitted from the display body 10 through the retardation layer 14 and the lens array layer 16. The light emitted from the display body 10 is visually recognized by the observer OB through the polarizer P.

Thereby, as FIG. 5 shows, the stereoscopic image S appears by the set of the enlarged images of the first phase difference unit 14a. Therefore, the visual effect of the display body 10 is enhanced as compared with a display body in which the latent image included in the retardation layer is displayed in a planar manner.
The display body 10 may be configured to display one stereoscopic image S or may be configured to display a plurality of stereoscopic images S.

  Such a display body 10 verifies the authenticity of the display body 10 and thus the authenticity of the article depending on whether or not the display body 10 attached to a predetermined article can display the stereoscopic image S by holding the polarizer P. It can be used to Moreover, the display body 10 may be used for decorating an article, or may be used as a part of a game article, for example, a game card.

[Manufacturing method of display body]
A manufacturing method of the display body will be described with reference to FIGS.
As FIG. 6 shows, when manufacturing the display body 10, the base material 11 is prepared first. The substrate 11 may be an unstretched film formed by extrusion or casting, a stretched film formed by stretching, or the like. When the substrate 11 is a stretched film, the substrate 11 may be a uniaxially stretched film or a biaxially stretched film.

  The material for forming the substrate 11 is, for example, cellulose, polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyolefin (PO), ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVA), polyvinyl chloride, polyethylene. One of naphthalate (PEN), polyethylene terephthalate (PET), nylon, acrylic resin, and triacetyl cellulose (TAC).

  When the substrate 11 is a stretched film, the direction in which the base material is stretched when creating the stretched film is the stretching direction. When the orientation regulating layer 13 is formed directly on the base material 11, the molecules contained in the orientation regulating layer 13 are oriented along the extending direction of the base material 11. Therefore, it is difficult to change the orientation regulation direction in the orientation regulation layer 13 to a desired direction other than the stretching direction.

  As shown in FIG. 7, the reflective layer 12 is formed on one surface of the substrate 11. The material for forming the reflective layer 12 is, for example, at least one selected from the group consisting of elements such as Al, Sn, Cr, Ni, Cu, Au, Zn, Si, and Ag, or from this group What is necessary is just to be at least one compound selected. The reflective layer 12 can be formed using, for example, a vacuum deposition method, a sputtering method, a CVD method, or the like.

  Of the reflective layer 12, the surface opposite to the surface in contact with the substrate 11 is the surface, and the surface of the reflective layer 12 may be a flat surface or a step surface having a fine uneven shape. May be. In the configuration in which the surface of the reflective layer 12 is a stepped surface, a concavo-convex shape such as a hologram can be adopted as a fine concavo-convex shape.

  As shown in FIG. 8, a photosensitive layer 13 p that is a precursor of the alignment control layer 13 is formed on the surface of the reflective layer 12. The material for forming the photosensitive layer 13p is, for example, any one of azobenzene derivatives, cinnamic acid esters, coumarins, chalcones, benzophenones, and polyimides. An azobenzene derivative, cinnamic acid ester, coumarin, chalcone, benzophenone, and polyimide are examples of photoreactive molecules that exhibit characteristics that regulate the orientation direction of liquid crystal molecules by light irradiation.

  When the forming material of the photosensitive layer 13p is an azobenzene derivative, the orientation regulating layer 13 has a predetermined orientation angle by photoisomerization of the azobenzene derivative by irradiation with polarized light. When the material for forming the photosensitive layer 13p is cinnamic acid ester, coumarin, chalcone, and benzophenone, these derivatives undergo photodimerization or photocrosslinking by irradiation of polarized light, whereby the orientation-regulating layer 13 has a predetermined content. Has an orientation angle. When the forming material of the photosensitive layer 13p is polyimide, the alignment regulating layer 13 has a predetermined alignment angle by photodecomposing the polyimide by irradiation of polarized light.

  The photosensitive layer 13p can be formed by applying the above-described forming material to the surface of the reflective layer 12 using any one of the application methods such as the gravure coating method and the die coating method.

  Since the reflective layer 12 is located between the base material 11 and the photosensitive layer 13p, even if a stretched film is used as the base material 11, the stretch direction in the base material 11 is formed on the surface of the reflective layer 12. The influence on the direction in which the molecules contained in the conductive layer 13p are oriented is suppressed. Therefore, even if a stretched film is used as the base material 11, the orientation regulation direction in the orientation regulation layer 13 can be set to a desired direction, and thus the degree of freedom of the formation method in the base material 11 is increased. .

  As shown in FIG. 9, the mask layer M is used to irradiate the photosensitive layer 13p with the first polarized light. In the photosensitive layer 13p, the surface opposite to the surface in contact with the reflective layer 12 is the surface. The angle formed by the X direction in the photosensitive layer 13p and the polarization direction of the polarized light emitted from the polarized light source that irradiates the photosensitive layer 13p with polarized light is the polarization angle. The angle formed by the X direction and the polarization direction of the first polarization is the first polarization angle. The polarization angle may be defined as an angle at which the Y direction and the polarization direction of polarized light are formed. In addition, when the polarized light is irradiated to the photosensitive layer 13p a plurality of times, and the portion of the photosensitive layer 13p irradiated with the first polarized light is irradiated with the polarized light for the second time and thereafter, the first polarized light is irradiated. The angle and the first orientation regulation angle may be different.

  The mask M has an opening Ma corresponding to the first restriction portion 13 a in the orientation restriction layer 13. The material for forming the mask M may be any of resin, glass, metal, and the like, and any material that can shield the first polarized light may be used.

  When the first polarized light is irradiated to the photosensitive layer 13p using the mask M, the first polarized light is applied to the portion of the photosensitive layer 13p that overlaps the opening Ma in the direction in which the mask M and the photosensitive layer 13p overlap. Is irradiated. Of the photosensitive layer 13p, the portion irradiated with the first polarized light is the irradiated portion, and some of the molecules contained in the irradiated portion are rearranged anisotropically. Alternatively, the chemical reaction proceeds anisotropically in some of the molecules contained in the irradiated part. As a result, in the photosensitive layer 13p, a precursor portion 13ap having an alignment regulation direction corresponding to the first polarization angle of the first polarized light is formed in the irradiated portion.

  As shown in FIG. 10, the entire photosensitive layer 13p is irradiated with second polarized light having a second polarization angle that is a polarization angle different from the first polarized light. Thereby, the orientation control layer 13 including the plurality of first control portions 13a and the second control portions 13b is formed. In the orientation restricting layer 13, the first restricting portion 13a has a first restricting angle θr1, and the second restricting portion 13b has a second restricting angle θr2 different from the first restricting angle θr1. The thickness of the orientation regulating layer 13 is, for example, not less than 10 nm and not more than 500 nm.

  In addition, you may irradiate 2nd polarized light only to parts other than the to-be-irradiated part among the photosensitive layers 13p instead of the whole photosensitive layer 13p. Even in such a method, the first restricting portion 13a and the second restricting portion 13b having a restriction angle different from that of the first restricting portion 13a can be formed. In this case, the 1st control part 13a is formed by irradiating the photosensitive layer 13p with 1st polarized light.

  Further, an image based on the first phase difference portion 14a is generated by holding the polarizer over the display body 10 without irradiating the photosensitive layer 13p with the second polarized light. Here, in the photosensitive layer 13p, the molecules contained in the photosensitive layer 13p are arranged at random. For this reason, in the orientation regulating layer formed only by irradiation with the first polarized light, the portion that fills the space between the plurality of first regulating portions is a non-regulating portion in which molecules are arranged randomly. Therefore, a non-oriented portion having no specific orientation is formed in a portion of the retardation layer that overlaps with the non-regulating portion.

  There is a possibility that a display body having such a non-orientation part displays an image based on the non-orientation part without holding a polarizer over the display body. Therefore, it is preferable that the whole alignment control layer 13 has regular anisotropy.

  As shown in FIG. 11, the retardation layer 14 is formed on the surface of the orientation regulating layer 13 opposite to the surface in contact with the reflective layer 12. When the retardation layer 14 is formed on the alignment restriction layer 13, a plurality of liquid crystal molecules included in the retardation layer 14 are aligned along the alignment restriction direction in the alignment restriction layer 13. Accordingly, the retardation layer 14 includes a first retardation portion 14a including liquid crystal molecules aligned along the first restriction direction Dr1, and a second retardation including liquid crystal molecules aligned along the second restriction direction Dr2. Part 14b is formed. The thickness of the retardation layer is, for example, not less than 0.5 μm and not more than 3.0 μm.

  The material for forming the retardation layer 14 is, for example, a photocurable liquid crystal monomer having an acrylate at both ends of a mesogenic group, a polymer liquid crystal that is cured by irradiation with an electron beam or ultraviolet light, and a main chain that is branched from the main chain of the polymer. Examples thereof include a polymer liquid crystal having a mesogenic group bonded thereto, and a liquid crystal polymer in which the main chain of the molecule is aligned along the alignment regulating direction. Each of these photocurable liquid crystal monomers and the three types of polymer liquid crystals are examples of liquid crystal molecules.

  In the liquid crystal, the temperature at which the phase transition from the nematic phase to the isotropic phase is the NI point, and after applying the liquid crystal material on the alignment control layer 13, the liquid crystal material is heat-treated at a temperature about 5 ° C. lower than the NI point. By doing so, alignment of liquid crystal molecules can be promoted.

By applying these forming materials to the surface of the retardation layer 14 opposite to the surface in contact with the orientation regulating layer 13 using any one of the coating methods such as gravure coating and die coating, an adhesive layer 15 can be formed.

  Then, the lens array layer 16 is bonded to the surface of the adhesive layer 15 opposite to the surface in contact with the retardation layer 14. Thereby, the display body 10 demonstrated previously with reference to FIG. 1 can be obtained.

  As a material for forming the lens array layer 16, for example, a thermoplastic resin or an actinic ray curable resin that is cured by an actinic ray such as ultraviolet rays can be used. Here, the thermoplastic resin is an acrylic resin, an acrylonitrile resin, an acrylonitrile polystyrene copolymer, a polycarbonate resin, a cycloolefin resin, a polyester resin, a styrene resin, an acrylic / styrene copolymer resin, or the like. The actinic radiation curable resin is acrylate, methacrylate, epoxy resin or the like.

  For example, the support layer 16b and the lens 16a constituting the lens array layer 16 are formed at the same time by melt molding in which the original plate is pressed against a molten thermoplastic resin to give the structure of the lens 16a to the surface of the thermoplastic resin. can do. Further, for example, a molten thermoplastic resin is applied to a substrate corresponding to the support layer 16b to form a coating film, and then the thermoplastic resin is cured in a state where the original plate of the lens 16a is pressed against the coating film. Thus, the lens array layer 16 can be formed.

As explained above, according to 1st Embodiment of the display body and the observation method of a display body, the effect enumerated below can be acquired.
(1) Since the latent image included in the retardation layer 14 as the first retardation portion 14a appears as a stereoscopic image when the polarizer P, which is a verifier, is held over the display body 10, the display body 10 The visual effect of increases.

(2) Since the adhesive force between the liquid crystal molecules and the adhesive layer 15 is larger than the adhesive force between the photoreactive molecules and the adhesive layer 15, the lens array layer 16 faces the alignment regulating layer 13. In comparison, the lens array layer 16 and the layer facing the lens array layer 16 are more firmly bonded.

Alternatively, the phase difference layer 14 may be in contact with the alignment regulating layer 13 and the adhesive layer 15 may be in contact with the adhesive layer 15. In short, in the display body 10, the orientation regulating layer 13 and the retardation layer 14 may be sandwiched between the reflective layer 12 and the lens array layer 16. Even if it is such a structure, the effect equivalent to (1) and (3) mentioned above can be acquired.

In such a configuration, it is preferable that the base material 11 is an unstretched film in order to prevent molecules contained in the orientation regulating layer 13 from being oriented along the stretching direction of the base material 11.

  The orientation regulation layer 13 may include three or more portions having different orientation regulation directions. Such an orientation-regulating layer can be formed by performing exposure on the photosensitive layer 13p three or more times and using a mask having different transmission parts in each exposure. Or such an orientation control layer can be formed also by using the mask containing a polarizer as a mask used for exposure of the photosensitive layer 13p.
