[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method of manufacturing an optical part using a photopolymerizable material or a method of manufacturing an optical part mother used for manufacturing the optical part.

2. Description of the Related Art Conventionally, a regular fine pattern is formed on a diffuser plate of a focal portion of a single-lens reflex camera, as disclosed in JP-A-57-148728 and JP-A-55-90931. However, these conventional optical components are relatively small (24 m
However, there is a tendency that the patterns that can be formed are also limited, and formation of a microlens continuous body or a microlens group as a precise optical device is not mentioned.

On the other hand, the progress of entertainment information devices such as televisions and displays has been remarkable, and the competition in the market has shifted not only to the enlargement of screens of televisions and displays but also to performance centering mainly on brightness and contrast.

Rear projection type products are predominant because a 40-inch type, that is, a large-screen television or display having a diagonal length of 1 meter or more can see an image even in a bright place. In a rear projection type projection television or display, a Fresnel lens sheet and a lenticular lens sheet in which fine particles for diffusing light are dispersedly arranged as disclosed in JP-A-58-192022. A screen that is called a combination of two sheets is used.

However, since the conventional transmissive screen attaches great importance to the widening of the viewing angle by the diffusing material, the brightness and the contrast have to be sacrificed, and the improvement thereof has been earnestly desired. A so-called fly-eye screen, which is a continuous microlens body, is disclosed in JP-A-61-97609 as a means for improving the drawbacks of these conventional transmission screens, but the manufacturing method is not mentioned.

Further, as a display unit of a thin and light television or an image source of a projection television, a liquid crystal display device has begun to spread in place of a conventional cathode ray tube. However, in a TFT liquid crystal display device excellent in image quality performance, it is used as a liquid crystal element. The light-transmitting area of the liquid crystal display device is only 10 to 50% of the effective area of the liquid crystal display device, the light amount of the light source is not effectively used, the screen cannot be brightened, or a light source larger than necessary is used. .

[0008]

As described above, according to the above-mentioned prior art, it was not possible to manufacture a precise and large microlens continuous body or microlens group industrially, that is, at low cost and with good productivity. Therefore, it has not been possible to manufacture a bright and high-contrast fly-eye screen that is optimal for use in a large-screen projection television or display. Further, the liquid crystal display device has a drawback that the screen cannot be made bright.

The main object of the present invention is to provide a precise and large continuum of microlenses, a microlens group or a substantially microlens or lenticular lens group designed in an arbitrary shape, and a combination of the lens group and other shape elements. It is an object of the present invention to provide a manufacturing method for industrially, that is, inexpensively and highly productively manufacturing an optical component having a shape (hereinafter, these may be collectively collectively referred to as a substantially microlens group).

At the same time, a bright and high-contrast fly-eye screen optimal for use in a large-screen projection television or display that can be industrially manufactured by using the above-described manufacturing method and the utilization efficiency of the light amount of the light source are improved to improve the brightness of the screen. An object is to provide a liquid crystal display device with improved lightness. Further, it is another object of the present invention to provide a manufacturing facility suitable for manufacturing a precise and large-sized substantially microlens group industrially, that is, at low cost and with high productivity.

[0011]

The above-mentioned main object is to provide a photopolymerizable material layer in contact with a base material, and to irradiate a light ray through a photomask, preferably through the base material, thereby applying the photopolymerizable material to the photopolymerizable material. After polymerization or cross-linking according to the pattern formed on the mask, the soluble (non-polymerized or cross-linked) portion of the photopolymerizable material is eluted in the developing solution and the remaining portion (polymerized or cross-linked portion) is eluted. ) Is developed.

By using the light-polymerizable material and the base material as materials having characteristics compatible with optical component components, it is possible to directly manufacture an optical component, and also to prepare the light-polymerizable material and the base material. Even if the material is a material that does not match the characteristics of the optical component, the component created by the above method is used as an optical component mother to obtain a stamper by transferring the mother surface by a method such as electroforming, and the optical component is then mounted on the stamper. An optical component can be similarly produced by molding a synthetic resin having characteristics suitable for the constituent elements.

The ray used may be far infrared ray, near infrared ray, visible ray, near ultraviolet ray, far ultraviolet ray or the like, but it is close to the viewpoint of life of material, safety of light ray, time required for polymerization and the like. The use of UV light is preferred.

The microlens group required for a transmissive screen and a liquid crystal display device is for diffusion and / or light collection, and the lens surface has a rotational symmetry such as a spherical surface, a spheroid, a paraboloid of revolution, or the like. There is a case where it has a non-rotationally symmetric surface and a case where it is composed of a non-rotationally symmetric surface. These shapes can be achieved by changing the photomask, light irradiation conditions or the light diffusion characteristics of the light polymerizable material.

In the case of a large area component, it is necessary to provide a photopolymerizable material layer on the entire surface of the substrate with a uniform thickness without any defects.
It is not easy, but the photopolymerizable material tank whose surface is treated so that the inner surfaces of the bottom wall and the side wall absorb the light used for polymerizing or crosslinking the photopolymerizable material is filled with an appropriate amount of the liquid photopolymerizable material. Arranging the base material so that the lower surface of the base material is in contact with the liquid surface of the liquid photopolymerizable material, and irradiating light rays through the base material through a photomask to polymerize the liquid photopolymerizable material or After cross-linking and separating the base material from the liquid surface, the soluble portion (non-polymerized or cross-linked portion) of the photopolymerizable material is eluted and developed. Moreover, it is possible to form a substantially microlens group while eliminating waste of materials.

[0016]

According to the present invention, it is not necessary to provide a photopolymerizable material layer on the entire surface of the substrate with a defect-free and uniform thickness, and a photomask, light irradiation conditions or light diffusion characteristics of the photopolymerizable material. Since the formation pattern (the shape of the portion of the photopolymerizable material that has been polymerized or crosslinked) can be controlled relatively arbitrarily by changing, the large-sized optical component having the substantially microlens group can be manufactured at low cost and with high productivity.

EXAMPLES Examples will be described below with reference to the drawings. Figure 1
FIG. 2 is a process flow chart schematically showing the first half of the manufacturing process of an optical component in which a substantially microlens group, which is an embodiment of the present invention, is formed on one side, and FIG.

In FIGS. 1 and 2, 10 is a photomask, 20 is a substrate, 30 is a photopolymerizable material (unpolymerized) layer,
40 is a light beam generator, 50 is an elution developing tank, 60 is a finished product which is an optical component equipped with a microlens group, 31 is a polymerized portion of a light-polymerizable material, 32 is an unpolymerized portion of a light-polymerizable material, and 41 is Illuminator, 42 a reflector, 43 a light beam, 5
Reference numeral 1 is an elution developer, 52 is a stirring device, 53 is a temperature control device, and 61 is a formed microlens group.

The photomask 10 is formed by forming a so-called pattern for controlling the transmission of light rays on a base material that sufficiently transmits the light rays used for polymerizing or crosslinking the light-ray-polymerizable material. The pattern is formed with a shade such as a negative.

In the photomask 10 of this figure, it is difficult to describe the shading in the figure, so the shading is replaced by the thickness of the photomask 10. After the steps (a), (b), and (c) are sequentially performed in FIG. 1, the steps (d), (e), and (f) are sequentially performed in FIG. 2 to complete the process.

A detailed description will be given below. First, a photomask 10, a transparent substrate 20 provided with a photopolymerizable material (unpolymerized) layer 30 on its surface, and a light beam generator 40 are prepared (step a in FIG. 1), and then the photomask 10 is subjected to light beam polymerization. Of a light-curing material (unpolymerized) layer 30 on the surface, which is transparent enough to transmit light rays used for polymerization or crosslinking of the light-polymerizable material (step b in FIG. 1) Device 4
By moving 0 in the lateral direction above the photomask 10, the photomask 10 is scanned with the light beam 43 (step c in FIG. 1).

As a result, the photopolymerizable material (unpolymerized) layer 3 corresponding to the pattern formed on the photomask 10 is formed.
At 0, there are a polymerized portion 31 and an unpolymerized portion 32. When the scanning of the light beam 43 is completed, a light-polymerizable material (unpolymerized) in which a polymerized portion 31 and an unpolymerized portion 32 are formed
The layer 30 together with the base material 20 is dipped in a separately prepared elution developing solution 51 in an elution developing tank 50, and the elution developing solution 51 is stirred and flowed by a stirring device 52 to elute and develop the unpolymerized portion 32 (see FIG. 2). Step d).

If necessary, the developed substrate 20 and the polymerized portion 31 are washed and dried, and then again scanned with the light beam 43 and post-cured (completely polymerized) (step e in FIG. 2), and the microlens is used. The optical component 60 including the group 61 is obtained (step f in FIG. 2).

In the elution and development step (step d in FIG. 2), the point of this process is to strictly control the temperature of the elution and development solution 51 by the temperature controller 53. By using a photomask in which the cross-sectional shape (shading) of the pattern of the photomask 10 is the same in one direction (the front-back direction of the paper in FIG. 1), a continuous lenticular lens can be easily manufactured. A lens (group) will be described as a representative.

Another embodiment will be described with reference to FIG. Figure 3
Unlike the previous example, which was an example of a manufacturing method for directly manufacturing an optical component having a microlens group, treats the formed microlens group as a mother for optical component molding and converts it into a stamper by electroforming. Then, a flow chart of a process for producing a large number of optical components from this stamper is shown.

In FIG. 3, the same numbers as those in FIG. 1 indicate the same acting substances. 70 is a mother, 80 is a stamper, 90a and 90b are finished optical components, 91 is a formed microlens group, and 92 is an optical substrate.

First, the steps will be described. Similar to the previous embodiment, in FIG. 3, exposure (step c), elution development (step d) are performed (some steps are omitted to avoid complexity of the description), and a completed microlens group 61 is provided. Base material 2
0 is converted into a stamper 80 by a known method such as electroforming (step g) as a mother 70 for molding an optical component, and then a synthetic resin is formed by a known molding method such as casting, injection molding, compression molding or the like. Is shaped to obtain the optical component 90a or 90b.

In the optical component 90a, two stampers 80 are formed by electroforming (step g), and the stampers 80 are attached to a mold that holds the two stampers with a predetermined gap, and acrylic resin, styrene resin, or the like is placed in the gap. It is obtained by casting, injection molding or compression molding a synthetic resin. In the optical component 90b, one stamper 80 is formed by electroforming (step g), and the stamper and the other surface of the optical substrate 92 whose one surface is previously processed into a Fresnel lens shape are used to form an acrylic resin in the formed void. ,
It is obtained by casting, injection molding or compression molding a synthetic resin such as styrene resin.

In the optical component 90a, the two sides have the same shape, but the mother 70 has a different shape on both sides.
By using, it is possible to similarly manufacture optical components having different shapes on both sides. In particular, an optical component having a flat surface on one side can be easily manufactured by molding in a space combined with a stamper having a flat surface or by forming a microlens group on an existing plate material.
It goes without saying that an optical device such as a liquid crystal display device or an image pickup device can be used as the base material.

In the above embodiment, the exposure was performed through the substrate, but FIG. 4 shows another embodiment. 4, the same reference numerals as those in FIGS. 1, 2 and 3 indicate the same functioning objects. Figure 4
Refer to. The light ray polymerizable material (resin layer) 30 provided on the surface of the substrate 20 through the light beam 43 through the photomask 10.

In this method, since the distance d between the photomask 10 and the photopolymerizable material (resin layer) 30 can be reduced, the pattern drawn on the photomask 10 can be accurately printed.

Further, in this method, since the light ray 43 does not need to pass through the base material 20, the base material 20 does not need to be light transmissive, and the base material 20 such as a liquid crystal display device, an imaging element device, a metal material, etc. The material can be freely selected. As a photopolymerizable material, a positive resist,
A negative resist, an ultraviolet curable resin, a heat ray curable resin or the like is used, and an elution or developing solution suitable for the photopolymerizable material may be used.

Next, the shape control of the microlens group will be described with reference to FIGS. In the embodiments described so far, the light rays used for exposure are completely parallel rays or nearly parallel rays, and the process is to print a pattern drawn in shades on the photomask 10. Such light rays can be generated by the light ray generator shown in FIG.

In the figure, the same numbers as those in FIG. 5 indicate the same functioning objects. In FIG. 6, by changing the surface shape of the reflecting surface 42b to an elliptical surface, a parabolic surface, a spherical surface, or the like, or changing the surface property to smooth, satin, unevenness, or the like, a light ray 43c having an arbitrary directional characteristic can be obtained. The directivity can also be adjusted by the shape of the light control plate 44 (the length 1 and the interval t).

An embodiment in which a microlens group is controlled and formed by using a light beam whose diffusion directivity is adjusted will be described with reference to FIG.

1 is generated. Unpolymerized portion 32 of the remaining photopolymerizable material
As described above, elute and develop to obtain an optical component having a microlens group.

Diffusion directivity is a photopolymerizable material (unpolymerized).
It is also possible to use the above-mentioned substantially parallel rays by adding a diffusible material such as quartz powder, glass powder, limestone powder, or resin powder to control the scattering property.

Next, formation of a complicated shape in which the microlens group and other shapes are combined will be described with reference to FIG. FIG. 8 is a principle explanatory view showing a process of manufacturing an optical component having a complicated shape in which a microlens group and another shape are combined.

An unpolymerized portion, 60 is a completed product which is an optical component having a complicated shape including a microlens group.

First, from the upper side of the first photomask 10a for forming the microlens group, the diffusive directional light beam generator 4 is generated.

The parallel light beam generator 40b again irradiates and scans the parallel light beam through 0b, and superimposes another shape on the unpolymerized portion 32 of the light-polymerizable material (unpolymerized) layer to form a complicated structure. The shaped overlapping portion 31b is formed. Then, the complex-shaped optical component 60 (completed product) including the microlens group is obtained by the developing process described above.

The above embodiment requires a process of forming a layer of the photopolymerizable material (unpolymerized) 30 on the surface of the base material 20 in advance regardless of whether the material is light transmissive or non-transmissive. Although an example is shown, a photopolymerizable material (unpolymerized) is previously prepared by using an exposure apparatus as shown in the sectional view of FIG.
The process of forming 30 layers on the substrate 20 can be omitted,

Since the base material 20 is held so that the lower surface thereof contacts the liquid photopolymerizable material (unpolymerized) 30, a superposed portion 31 of the microlens group is formed on the lower surface of the base material 20.

When the irradiation scanning with the light beam 43 is completed, the base material 20 is removed from the holder 103 together with the superposed portions 31 of the formed microlens group, the unpolymerized material is dropped and reduced, and then the development is performed by the above-mentioned method. To do. Upon exposure, the light-shielding film 105 is a liquid photopolymerizable material (unpolymerized) 3
