In a non-contact state, strictly speaking, the display surface of the LCD element 3 and the feeling
It is a predetermined interval in a non-contact state with the photosensitive surface of the optical film 4
I try to keep them apart. In this embodiment, it is clear
This results in obtaining a transferred image
As mentioned above, the negative factor of increased light diffusion is
Less prism sheet 40 in the backlight unit 1
By providing both, it is a plus that suppresses light diffusion
It is to cover with factors. Suppression of light diffusion as described above
As a positive factor, the LCD element 3
The substrate 32 on the photosensitive film 4 side and the polarizing film 31 are combined.
Suppresses light diffusion by regulating the total thickness t
It is also possible to do. Thereby, the feeling with the LCD element 3
Even if the optical film 4 is separated by a predetermined distance, it is clear
A transfer image can be obtained. The first implementation described above
Like the transfer device shown in the embodiment, the display surface of the LCD element 3

be able to. In the LCD element 3 used in this embodiment,
At least with the substrate 32 on the photosensitive film 4 side.
The total thickness t combined with the optical film 31 is as much as possible.
It is good that it is thin, and 1.0 mm or less is preferable. Even better
Preferably 0.8 mm or less, and even more preferably 0.6 mm.
It is good to set it as mm or less. Still more preferably, the backlight
Unit 1 side substrate 36 and polarizing film 37 are combined.
The total thickness should be thin, preferably 1.0mm or less.
Yes. More preferably, it is 0.8 mm or less.
More preferably, it is 0.6 mm or less. Also,
The lower limit of the total thickness is not particularly limited,
For example, in the glass substrate 32, the thickness of itself is reduced.
Since the limit of about 0.5 mm is considered to be 0.
It is good also as 5 mm or more. This total thickness is
It is not limited to the
Consider using a resin substrate instead of a glass substrate.
It is also effective to consider,
The lower limit value of the total thickness can be further reduced. Hereinafter, in this embodiment, a photosensitive film is used.

10 mm, more preferably 0.1 mm to 5 mm
Good to do. This is represented by the columnar perforated plate 20.
The pattern of the through holes 22 of the linear light generating means
This is to prevent it from appearing in the form of a “shadow”.
Note that the interval set in this embodiment is
The above-mentioned “shadow” can be prevented, but the sharpness of the transferred image is reduced.
It is a condition not to let. The material of the perforated plate 20 is the second
The same thing as embodiment can be used. further,
The shape of the through hole 22 provided in the porous plate 20 is also the second embodiment.
It can be the same as the state. Like this embodiment
Even when the perforated plate 20 is used, the image quality is clear.
The degree becomes higher. For example, the thickness of the porous plate 20 is 6 m.
m, 0.5 mm diameter through holes 21 are closely packed and the pitch is
The one formed with 0.7 mm is used. In this case,
Geometrically, the diffusion angle of light from the through hole 21 is about 4.7 °.
It is. On the other hand, the prism sheet 40 is about ± 4 from the center.
Light is condensed in the range of 0 ° and passes through the perforated plate 20
About 10 times larger than the diffusion angle of light. For this reason,
Degree of travel and image quality of the transferred image are determined only by the perforated plate 20
It seems to be decided. However, the prism sheet 40 is installed.
Transfer images with excellent image quality.
Yes. FIGS. 12A to 12D show the fourth embodiment.
Positive showing the arrangement of through holes in the perforated plate used in the transfer device
FIG. 2A is a plan view in which three rows of through holes are formed.
(B) shows one row of through-holes.
Yes, (c) has four rows of through-holes
(D) is one in which two rows of through holes are formed.
Further, the through holes 22 are arranged when the plurality of through holes 22 are arranged in two or more rows.
The number and arrangement shape of the through-hole rows are not particularly limited.
There is no. For example, the array shape is a grid pattern or a staggered pattern (closest packed)
Shape), more preferably staggered
Yes. In addition, the number of arrays may be, for example, one column or several columns
Good, but especially when arranging in a staggered pattern among multiple rows
Even number columns are good. The reason for this is shown in FIG.
As shown in FIG.
In the case of the hole plate 20, the first and third columns in the A row and the C row
The light from the two through holes 22 illuminates the LCD element 3
And bright. However, in row B and row D, one of the second column
Only the light from the through hole 22 illuminates the LCD element 3
dark. For this reason, dark streaks are formed on the B and D lines.
The Further, a plurality of through holes 2 provided in the perforated plate 20
The arrangement pitch p of 2 (see FIG. 11A) is equal to the through hole 22.
Are uniformly arranged, and the display image of the LCD element 3 is clearly felt
Any pitch is acceptable as long as it can be transferred to the optical film 4.
And can be set appropriately according to the size of the through-hole 22
Yes. For example, the arrangement pitch p should be as fine as possible
Yes. In the present embodiment, the through hole 22 is used.
The distance d between the through hole 22 and the through hole 22 is not particularly limited.
However, it is more important than the arrangement pitch p and the size of the through holes 22
It is. The reason is that the distance d between the through holes 22 is large.
Then, the pattern of the above-described through hole 22 is caused by diffused light.
Between the perforated plate 20 and the LCD element 3 in order to eliminate the “shadow”
This is because it is necessary to increase the distance. So this
The distance d between the through holes 22 is, for example, the longitudinal direction (arrangement method).
Direction)) and converted to a distance y of 1 mm or less.
Is preferable, more preferably 0.5 mm or less,
Preferably, it is 0.2 mm or less. In addition,
The lower limit value of the distance d between the through holes 22 is particularly limited.
is not. However, considering the ease of production, the interval
The lower limit of d is preferably about 0.05 mm or more.
That's right. It should be noted that the penetration in terms of the distance in the longitudinal direction is
The interval d between the through holes 22 is large as shown in FIG.
When the arrangement of the through holes 22 in the hole plate 2 is one row,
Or, as shown in FIG.
If the column is close-packed, the closest through-hole 2
This is the distance d between the two, as shown in FIG.
If multiple rows (2 rows in the example shown) are staggered,
Closest when projected from a direction perpendicular to the longitudinal direction
This is the distance y between the through holes 22 in the longitudinal direction. In addition,
Longitudinal direction in the case of a staggered pattern as shown in FIG.
The interval x in the direction orthogonal to the interval y is more flexible than the interval y.
Large, for example, preferably 2 mm or less, more preferably
Is 1 mm or less, more preferably 0.5 mm or less
That is good. Thus, it is used for the transfer device of this embodiment.
In the perforated plate 20 to be manufactured, the intervals x and y are the same.
For example, y = 0.2 mm
However, since x = 0.5 mm or 1 mm may be used,
Important that production restrictions are eased and production is easy
It has the following features. The thickness t of the porous plate 20 ₁ (FIG. 11 (a)
(Refer to) is more than 3 times the diameter or equivalent diameter of the through hole 22
Is preferable, more preferably 5 times or more,
More preferably, it is 7 times or more. Na
The equivalent diameter mentioned above is “4 × area / total side length (or
It is the length represented by the “total circumference”. Perforated plate 20
The diameter or equivalent diameter of the through hole 22 is 5 mm or less,
The thickness t of the perforated plate 20 ₁ Is the diameter or phase of the through-hole 22
The above diameter is 3 times or more because these conditions are perforated plates.
20 because it is an effective condition for obtaining parallel light.
The Further, of the entire surface of the perforated plate 20, at least
In both cases, it is preferable that the inner surface of the through-hole 22 is formed of a low reflectance surface.
More preferably, the entire surface of the perforated plate 20 is low reflective.
It is good to configure in terms of rate. Here, the low reflectance surface is
For example, blackened surface or roughened surface
The surface that reduces the reflectivity of incident light.
Yeah. The method for forming the blackened surface is particularly limited.
For example, the material constituting the perforated plate 20 is not
A method using a black body or a blackening treatment on the surface
The method of doing is mentioned. For black material, for example
1% or more of carbon black powder (preferably 3%
Above) Contained materials or carbon powders
And so on. Examples of blackening treatment include, for example, paint
Packaging or chemical treatment (such as plating, oxidation or electrolysis)
Can be mentioned. On the other hand, the surface roughening treatment is also particularly limited.
For example, when machining holes,
Roughening method, mechanical processing method such as sandblasting
Or post-processing such as chemical processing such as etching
It is possible to use any method such as roughening by work.
It is. In this case, as the degree of roughening, for example,
About 1 μm to 20 μm is the effective range for the core wire average roughness
The In the present embodiment, the perforated plate 20
The reflectance of at least the inner surface of the through hole 22 is more preferable.
Alternatively, the reflection of the low-reflectance surface constituting the entire surface of the porous plate 20
The rate is preferably 2% or less, more preferably 1% or less.
