To be multilayer film.
Bonding layer 52 is set to want false proof article for display body 1 to be arranged on.Bonding layer 52 consider display body 1 with
Want the bond strength of false proof article and the flatness on composition surface etc. or more than 2 layers of structure.
In addition, depicting the structure of the display body 1 from the side of transmitance material layer 50 in fig. 2, but can also use
The structure of display body 1 from the side of layer of reflective material 51.
Then, the sag and swell being located on layer 2 is illustrated.
Layer 2 includes diffractive grating regions 10, the first light scattering sites 20a, the second light scattering sites 20b and region 30.
In diffractive grating regions 10, on the interface of transmitance material layer 50 and layer of reflective material 51, form
The diffraction grating pattern being made up of the diffraction grating of relief type.The diffraction grating for example arranges multiple grooves and formed.In addition, term
" diffraction grating " refers to producing the construction of diffracted wave by irradiating illumination light, such as is set to except matching somebody with somebody in parallel and equidistantly
Put outside the common diffraction grating of multiple grooves, in addition to the interference fringe recorded in hologram.In addition, groove or groove are clipped
Part is referred to as " grid stroke ".
The depth for forming the groove of diffraction grating is for example set in the range of 0.1~1 μm.In addition, the grating of diffraction grating is normal
Numerical example is such as set in the range of 0.5~2 μm.
In each of light scattering sites 20a and 20b, on the boundary of transmitance material layer 50 and layer of reflective material 51
On face, provided with the consistent multiple linear convex portions in direction and/or recess.In addition, in region 20a and region 20b, linearly
Convex portion and/or recess direction it is mutually different.
In the case where being illuminated from the normal direction in region to region 20a or 20b, the region with it is linear convex
In the vertical face of the length direction of portion and/or recess with most wide injection angular region, i.e. wide-angle project scattering light, with it is linear
Convex portion and/or recess length direction is parallel and face that interarea with above-mentioned zone is vertical in penetrated with most narrow injection angular region
Go out to scatter light.Hereinafter, by the size of the angular range of scattering light more than light scattering sites injection some strength, with term, " light dissipates
Penetrate can " show.For example, in the case where using term " light scattering energy ", above-mentioned optical characteristics can be recited as " region 20a
And the light scattering energy of minimum is presented in each of 20b on the length direction of linear convex portion and/or recess, perpendicular

In the range of 10 μm.
In the region 30, it is not provided with sag and swell on the interface of transmitance material layer 50 and layer of reflective material 51.
I.e., in the region 30, the interface of transmitance material layer 50 and layer of reflective material 51 is tabular surface.
Layer 2 for example can be by corresponding multiple sections (segment) are formed respectively with region 10,20a, 20b and 30.Or
Such as layer 2 can also be formed by multiple units with rectangular arrangement, and diffraction light is formed by a part for these units
Gate region 10, region 20a is formed by other parts of these units, area is formed by other other parts of these units
Domain 20b, region 30 is formed by remaining unit.In the case where forming layer 2 by multiple units, these units can be used respectively
Picture is shown as pixel.Hereinafter, the unit for forming diffractive grating regions 10 is referred to as " diffraction grating unit ", region will be formed
20a and 20b unit is referred to as " light scattering elements ".
In the case where forming layer 2 by a variety of units, if it is known that the visual effect of each unit, then easily to their row
Picture obtained by row are replaced is envisioned.Thus it is possible to each pixel is easily determined by according to digital image data to be made
Unit.Therefore, now the design of display body 1 becomes easy.
In order that intersegmental or pixel mesopic vision effect is different, content described below can be utilized.
First, it is described with reference to the visual effect obtained by diffractive grating regions 10.
Fig. 3 is represent to be incident to relation between the illumination light of diffraction grating and diffraction light emitted by diffraction grating one
The figure of individual example.
If make illumination light 71 from the direction vertical with grid stroke with incident angle α ' be incident to diffraction grating 11, diffraction light
Grid 11 project 1 diffraction light 73 as representative diffraction light using angle of emergence β.Normal reflection light (0 diffraction of diffraction grating 11
Light) 72 angle of reflection or angle of emergence α and incident angle α ' it is equal on absolute value, and symmetrical (α, β will sides clockwise relative to normal
To being set to positive direction).Angle [alpha] and angle beta the grating constant of diffraction grating 11 is set to d (nm), the wavelength of illumination light 71 is set
For λ (nm) when, meet the relation shown in following formula (1).
D=λ/(sin α-sin β) (1)
From above-mentioned formula (1), in the case where making white light incidence, the angle of emergence of 1 diffraction light is different according to wavelength
It is and different.That is, diffraction grating 11 acts on light splitting, and the color of diffractive grating regions 10 is with change observation position and with seven colors
Change.
In addition, the color that observer is felt based on certain observation condition changes according to grating constant.
For example, diffraction grating 11 is set to relative to projecting 1 diffraction light 73 on the vertical direction in the grating face.That is, if
Angle of emergence β for 1 diffraction light 73 is 0 °.Now, if by the angle of emergence of the incidence angle of illumination light 71 and 0 diffraction light 72
Absolute value is set to αN, then formula (1) is simplified as follows.
D=λ/sin αN (2)
From formula (2), in order that observer feels certain color, will wavelength X corresponding with the color, illumination light 71
Incidence angle absolute value αNIt is set as meeting the relation shown in formula (2) with grating constant.If for example, set wavelength as
400~700nm white light is illumination light 71, by the absolute value α of the incidence angle of illumination light 71N45 ° are set to, is used with diffraction light
The spatial frequency of grid is the diffraction grating being distributed in the range of the inverse of grating constant is 1800~1000/mm, then space frequency
Rate appears as blueness for the part of 1600/mm degree, and the part of 1100/mm degree appears as red.Therefore, pass through
Make the spatial frequency of diffraction grating between intersegmental or unit different, their display color can be made different.
In addition, the smaller easier formation of the spatial frequency of diffraction grating.Therefore, the common diffraction grating for display body
Spatial frequency is set to 500~1600/mm mostly.
In the above description, it is assumed that illumination light 71 is incident to diffraction grating 11 from the direction vertical with grid stroke.According to
The state, if in the state of direction of observation to be set to certain, diffraction grating 11 is set to be rotated around its normal, then grating constant
D virtual value changes according to its anglec of rotation.As a result, the color that observer is felt changes.In addition, if the rotation
Gyration is fully big, then observer can not feel diffraction light on above-mentioned direction of observation.So by making between intersegmental or unit
The orientation of grid stroke is different, their display color can be made different, or change the unit and look luminous due to diffraction light
Direction.
In addition, if increasing the depth of the groove of composition diffraction grating 11, then diffraction efficiency changes.In addition, if make to spread out
Grating is penetrated relative to the area of section or unit than increasing, then the intensity of diffraction light becomes much larger.
Therefore, if making the spatial frequency of diffraction grating and/or orientation different between intersegmental or unit, these can be made
Section or unit show different colors, or can set the condition of observable.In addition, if make to be formed between intersegmental or unit
The depth of the groove of diffraction grating 11 and diffraction grating 11 are different relative at least one party in the area of section or unit ratio, then can
Enough make the brightness of these sections or unit different.So by using these methods, full-color picture and space image iseikonia can be shown.
Then, it is described with reference to the visual effect obtained by light scattering sites 20a and 20b.
Fig. 4 is the top view for the example that outline represents light scattering sites.
Light scattering sites 20 shown in Fig. 4 include multiple light scattering construction 25.These light scattering construction 25 is respectively straight line
Shape, it is direction is consistent in each light scattering sites 20 multiple convex portions and/or recess.That is, in each light scattering sites 20, light dissipates
Penetrate 25 almost parallel arrangements of construction.
In addition, in each light scattering sites 20, light scattering construction 25 can also be not exclusively arranged in parallel.As long as light scattering area
Domain 20 has sufficient light scattering energy anisotropy, in the light scattering sites 20, such as can also a part light scattering structure
The length direction for making the 25 length direction light scattering construction 25 a part of with other intersects.Hereinafter, with light scattering sites 20
Main surface parallel direction among, by light scattering sites 20 present minimum light scattering can direction be referred to as " differently- oriented directivity ", will
The direction that the light scattering energy of maximum is presented in light scattering sites 20 is referred to as " light scattering axle ".In the present embodiment, due to by straight line
The construction of shape is as essential structure, therefore differently- oriented directivity is orthogonal with light scattering axle.
In the light scattering sites 20 shown in Fig. 4, the direction represented by arrow 26 is differently- oriented directivity, is represented by arrow 27
Direction is light scattering axle.If for example, be illuminated from the incline direction vertical with differently- oriented directivity 26 to light scattering sites 20, and
Detected by an unaided eye light scattering sites 20 from front, then light scattering sites 20 look brighter due to its higher light scattering energy
It is bright.On the other hand, if be illuminated from the incline direction vertical with light scattering axle 27 to light scattering sites 20, and used from front
Light scattering sites 20 are visually observed, then light scattering sites 20 are looked than dark due to its relatively low light scattering energy.
It follows that for example light scattering sites 20 are being illuminated from incline direction and are detecting by an unaided eye this from front
In the case of light scattering sites 20, if making light scattering sites 20 be rotated around its normal direction, its brightness change.So
Such as in the light scattering sites 20a and light scattering sites 20b shown in Fig. 1 using identical construct and in these regions 20a and
In the case of the direction difference for only making light scattering axle between 20b, when in region, 20a looks most bright, region 20b, which is looked, to be compared
Secretly, when in region, 20a looks most dark, region 20b looks brighter.In addition, when region 20b looks most bright,
Region 20a is looked than dark, and when in region, 20b looks most dark, region 20a looks brighter.
That is, by making light scattering axle 27 different in region 20a and region 20b, can make to produce lightness between them
Difference.Therefore, thus, it is possible to show picture.Especially, by the differential seat angle for the light scattering axle 27 for making region 20a and region 20b
Enough (although also relying on the size of lighting source, such as the big multi-configuration of lighting source on the ceiling interior
For more than 30 °) or make respective light scattering anisotropy fully big, can with the naked eye it be seen under respectively different observation condition
Examine the picture shown by respective region.By using the orthogonal light scattering structure of light scattering axle as light scattering sites 20a and 20b
Make, so as to observe that the condition as the picture shown by respective region turns into entirely different condition, can reliably divide
Not it was observed that respective picture.
The lightness of light scattering sites 20 can also be controlled by other method.
For example, the width of light scattering construction 25 is bigger, the light scattering on the direction of light scattering axle 27 can be smaller.The opposing party
Face, if made, light scattering construction 25 is elongated, and the light scattering in differently- oriented directivity 26 can diminish.
The shape of light scattering construction 25 can also be all identical in 1 light scattering sites 20.Or 1 light scattering area
Domain 20 can also include variform multiple convex portions and/or recess 25.
The light scattering sites 20 of light scattering construction 25 only including same shape easily carry out the design of light scattering energy.Separately
Outside, this light scattering sites 20 can be by the microfabrication such as electric wire drawing apparatus or steeper device come high-precision and easy
Ground is formed.On the other hand, according to the light scattering sites 20 for including variform light scattering construction 25, can obtain wider
There is the scattering light of gentle light intensity distributions in angular range.Thus it is possible to show the light and shade change as caused by observation position
Small and stable white.
In addition, the orientation degree of order of light scattering construction 25 is higher, the light scattering energy anisotropy of light scattering sites 20 is bigger.
In light scattering sites 20, light scattering construction 25 both can regularly configure by a certain degree, can also be randomly
Configuration.If for example, the interval in the direction parallel with light scattering axle 27 of light scattering construction 25 is set to random, with orientation side
The light intensity distributions of scattering light on the direction vertical to 26 become gentle.Therefore, it is suppressed that corresponding with viewing angle white
Degree or the change of lightness.
In addition, if reducing the interval of light scattering construction 25 on the direction parallel with light scattering axle 27, then can make more
More scatter incident lights, therefore the intensity of scattering light can be strengthened under conditions of light scattering anisotropy is deteriorated.Example
Such as, if the equispaced of the light scattering construction 25 on the direction parallel with light scattering axle 27 is less than 10 μm, can obtain
The light scatter intensity of the good display of visibility is realized enough.
In addition, if make the equispaced fully small, then the feelings being made up of in light scattering sites 20 multiple light scattering elements
Under condition, the size that can make light scattering elements enough is 100 μm or so.Now, can be with point of human eye under usual observation condition
Fineness below resolution shows picture.That is, the picture of enough high-fineness can be shown.
In Fig. 1, two light scattering sites 20a and 20b that light scattering axle is substantially orthogonal are configured with, but light can also be configured
Scatter the different light scattering sites of more than three of axle.
Fig. 5~Fig. 7 is the top view for the example for representing the construction available for light scattering sites.In Fig. 5~Fig. 7, white portion
Correspond respectively to convex portion or recess.
In Fig. 5 light scattering sites 20, light scattering construction 25 arranges in the y-direction.In Fig. 6 light scattering sites 20,
Light scattering construction 25 is along from the arrangement of the direction of 45 ° of y directions rotate counterclockwise.In Fig. 7 light scattering sites 20, light scattering construction
25 arrange along the x directions orthogonal with y directions.
Like this, if configuring the different light scattering sites of more than three of light scattering axle, such as gray scale can be carried out
It has been shown that, or make the change of picture more complicated with the orientation for changing display body 1.For example, the orientation by changing display body 1,
Also picture can be changed in animated way.
Fig. 8 and Fig. 9 is the top view for the other examples for representing the construction available for light scattering sites.
In Fig. 8 light scattering sites 20, light scattering construction 25 arranges in the y-direction.In Fig. 9 light scattering sites 20,
Light scattering construction 25 arranges in the x-direction.
For light scattering construction 25 shown in Fig. 8 and Fig. 9 compared with the light scattering construction 25 shown in Fig. 5~Fig. 7, width is wider.
Thus, the scattering light emitted by the light scattering sites 20 shown in Fig. 8 and Fig. 9 is penetrated with the light scattering sites 20 shown in Fig. 5~Fig. 7
The scattering light gone out is compared, and the diffusion to the direction vertical with differently- oriented directivity 26 is less.
In the case where the diffusion of scattering light is few, become from scattering light when determining position observation by force, therefore, for being dissipated by light
Penetrate multiple regions that direction is identical and the width of light scattering construction 25 is different of axle 26, the light scattering sites 20 shown in such as Fig. 5
And the picture that the light scattering sites 20 shown in Fig. 8 are formed, when from defined position, it appears that as with deep or light picture.
In addition, the light scattering sites 20a and 20b shown in Fig. 1 and Fig. 2 are not limited to shown in Fig. 5~Fig. 7 and Fig. 8 and Fig. 9
Light scattering sites 20, various structures can be used.
As described above, there is clear and definite transition effect by Fig. 1 light scattering sites 20a and the 20b picture shown.That is, by having
Two pictures that two light scattering sites 20a and 20b for having mutually different light scattering axle 27 are shown, which look, not to be mixed, and can
Separately observed by visually clear.In addition, by setting multiple light scattering sites with different light scattering axles 27
20, display body 1 can be made to show picture according to the identical quantity of light scattering axle 27 with setting.Thus, additionally it is possible to produce by observing
The picture change of cartoon type caused by the change of position.
Light scattering construction 25 both can be 2 values (binary) construction or continuous change in depth or short transverse
The construction of change.
The light scattering sites 20 of light scattering construction 25 including 2 value constructions can utilize the device with microfabrication ability
Relatively easily manufacture, additionally it is possible to easily carry out the setting of shape etc..The light scattering construction 25 of construction including consecutive variations
Light scattering sites 20 speckle is recorded in photosensitive material, on such as photoresist by using the interference of laser, can
Easily manufacture.When the area of the part provided with light scattering construction 25 constructs relative to the area of light scattering sites 20 in 2 values
In the case of being 100% i.e. no even surface in the construction of consecutive variations for 50%, the light scattering in light scattering sites 20
The scattering efficiency highest of construction 25.
The layer 2 of display body 1 shown in Fig. 1 and Fig. 2 include the mutually different two light scattering sites 20a of light scattering axle and
20b.Light scattering sites 20a using character " 9 " as showing, in addition light scattering sites 20b using the edge of the character " 9 " as
As showing.
In Fig. 1 display body 1, light scattering sites 20a and 20b respective light scattering axle are mutually orthogonal.As described above,
In the case of light scattering sites 20a or 20b from relative to the vertical direction of differently- oriented directivity 26, display light diffusion, therefore
Regardless of viewing angle, bright picture can be observed.Therefore, if from the differently- oriented directivity 26 with light scattering sites 20a
Vertical direction observation display body 1, then only character " 9 " looks relatively white, and edge looks dark.On the other hand, if from
Display body 1 is observed in the direction vertical with light scattering sites 20b differently- oriented directivity 26, then the edge of only " 9 " looks whiter.That is,
Fig. 1 display body 1 is due to including light scattering axle mutually different two light scattering sites 20a and 20b, therefore region 20a and 20b
Light and shade reversed according to the orientation of display body 1.
Display body 1 shown in Fig. 1 and Fig. 2 is due to two mutually different light scattering sites of the direction including light scattering axle 27
20a and 20b, therefore picture pre-determined respectively can be observed from the direction different corresponding to axle from scattering.It is this according to sight
It can also be showed although examining the change for the picture that position is observed by diffractive grating regions 10, seven with diffractive grating regions 10
Colored performance is different, and almost uniform whiteness is appeared to be in wider observation position range.
In addition, the transmission material layer 50 for having enumerated Fig. 2 as an example above does not have the suction specified in visibility region
The situation of take-up, illustrate the scattering light of white.In the case where transmission material layer 50 includes dyestuff etc., light scattering sites
20 scattering light is the scattering light of the wavelength components of transmission transmission material layer 50.
Display body 1 shown in Fig. 1 and Fig. 2 is in addition to diffractive grating regions 10 and light scattering sites 20a and 20b, also
Region 30 including being not provided with sag and swell.Region 30 is in addition to observing the position of normal reflection light, even if changing observation position
Put, the picture felt also does not change.In the situation that the transparent material layer 50 as shown in Figure 2 of layer 2 and layer of reflective material 51 are formed
Under, the metallic appearance of layer of reflective material 51 is presented in region 30.
That is, the synthesis of display body 1 shown in Fig. 1 and Fig. 2 possesses：The vision greatly changed with observation position with performance is imitated
The two of the observing effect of the diffractive grating regions 10 of fruit, the switching with mutually orthogonal light scattering axle 27 and with picture and stabilization
Individual light scattering sites 20a and 20b and performance be not with the region 30 that viewpoint changes, and therefore, the display body 1 has complicated
Visual effect.And then in the display body 1 shown in Fig. 1 and Fig. 2, each region independently shows picture, therefore with only passing through diffraction light grid region
One party in domain 10 or light scattering sites 20a and 20b shows that the display body of picture is compared, and there is more complicated vision to imitate
