2. Description of the Related Art A liquid crystal display (LCD) is rapidly becoming widespread as a thin, lightweight, and low power consumption variable display device. Of the LCDs, the one that directly looks at the display surface of the display is called the direct-view type. Direct-view LCD
Include a transmissive type that incorporates a light source such as a fluorescent lamp on the back surface, and a reflective type that uses ambient light. Of these, the transmissive type requires a backlight and is not suitable for power saving.

On the other hand, the reflective LCD has an ECB (Electr
ically controlled birefrigenece) mode, GH (Gue
st Host) mode, TN (Twisted Nematic) mode, etc. are used. A polarizing plate is required when using the ECB mode or the TN mode, but since the polarizing plate has a light transmittance of about 40%, the utilization efficiency of light deteriorates. Also, GH
When using the mode, a polarizing plate is not necessary, but in the case of full-color display, it is necessary to stack three or more layers of monochromatic liquid crystal cells having a transmittance of about 80%, and therefore the light utilization efficiency is not so high. When displaying in color, EC
When B mode or GH mode is used, a color filter is not required, but color reproducibility is poor and viewing angle dependency is large. TN
When the mode is used, color is added with a color filter, but since it is a reflective type, the light utilization efficiency is only about 1/3.

Further, a TFT (Th
If an in-film transistor (TFD) or a thin film diode (TFD) is provided, the aperture ratio will be low.

Therefore, it is difficult for the reflection type LCD to increase the reflection brightness due to the restrictions on the light utilization efficiency and the aperture ratio, and it is not possible to make the screen as bright as paper white.

Further, although the power consumption of the reflective LCD is relatively low, it is necessary to drive it with an alternating current of 60 Hz or more, instead of direct current, in order to prevent deterioration of the liquid crystal even when displaying a still image. Cannot be zero.

In recent years, a movable film type display device has been proposed as a new variable display device which is thin, lightweight and has low power consumption (Japanese Patent Laid-Open Nos. 8-271933 and 10-15).
3741). FIG. 1 shows a schematic cross-sectional view for explaining the basic principle of a movable film type display device. According to the basic principle of the movable film type display device, the movable display unit 2 of a color different from that of the fixed display unit is hidden behind or inside the fixed display unit 1 which constitutes the background of the display screen. Display can be performed by inserting and removing the movable display unit from the gap. More specifically, as shown in FIG. 1, a background color film such as a white film is arranged in a tiled roof shape to form a fixed display portion 1, and a black film is displayed behind it as a movable display portion 2 in black and white display. , In color display, CMY
The color films such as the above are hidden, and the movable display portions are put in and taken out from the gaps of the respective background color films in accordance with the image information to be displayed and viewed (reference numeral 3).

FIG. 2 is a conceptual diagram for explaining the driving principle of the movable film member 7. The movable film member 7 including the movable display unit 2 has a colored film 9 connected to one end of a flexible support film 8, and the colored film is angled about 90 degrees in the bending direction (normal direction) of the support film. The movable display portion 2 is formed by bending the electrode 1 into an electrode (referred to as a movable electrode) 1 on the body portion of the support film.
0 is attached to form a movable electrode unit.

On the other hand, in the fixed film member 4 having the fixed display portion 1, a colored film 6 as a background color is connected to one end of the support film 5, and the colored film is angled about 90 degrees in the normal direction of the support film. It has a basic configuration in which the fixed display portion 1 is formed by bending it.

As shown in FIG. 2a, the movable film member 7
Is aligned with the background color film constituting the fixed display portion 1 and stands substantially vertically, and further, the fixed electrode 11 is arranged so as to face the support film 8 of the movable film member and fixed to the movable electrode 10 of the support film. The electrode 11 forms a capacitor. Further, instead of arranging the fixed electrode 11, a fixed electrode for forming a pair with an adjacent movable electrode may be provided on the support film 5 of the fixed film member 4 to form a capacitor. And, as shown in FIG. 2b,
An electrostatic force is generated by the potential difference between the movable electrode 10 and the fixed electrode 11, and the vertically movable movable film member is swung in the front-back direction of the support film, whereby the movable display unit 2
Can be displayed in front of the fixed display unit 1 or retracted behind it to display one pixel.

Fixed film member 4 and movable film member 7
By arranging the pixel drive units composed of the fixed electrodes 11 and the fixed electrodes 11 in a matrix as shown in FIG. 3 and controlling the moving in and out of the movable display unit for each pixel according to the electronic information of the image to be displayed, It is possible to display an arbitrary image. When displaying in black and white, a white fixed display portion is used and a black movable display portion is arranged in a matrix. On the other hand, when performing color display, as shown in FIG. 4, the white fixed display unit 1 is used and the YMC
The movable display portions 2 (2Y, 2M, 2C) of the respective colors are arranged in a matrix, and the movable display portions of the respective colors are controlled to be superposed on each other to perform subtractive color mixing.

The movable film type display device has a high reflection efficiency and can display a particularly bright white color. In principle, a omnidirectional high reflection white display similar to paper white, and a high image quality comparable to printing. Full color display can be realized. In addition, in principle, the power consumption is extremely low, and since it has a non-volatile memory effect, the power consumption can be zero when displaying a still image.

However, if the colored film and the supporting film are separately manufactured for the fixed film member or the movable film member, a very accurate bonding step is required when bonding the colored film and the supporting film. Because of the problem that wrinkles occur in
There was a problem that the yield became poor.

Further, the coating method has an advantage that the manufacturing cost is lower than that of the vacuum process. Further, since it becomes possible to use a resin having a high heat resistance as the binder, in that case, it is possible to prevent film fusion to the heating jig when folding the movable film member, and further in a high temperature environment.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below. The display unit film member according to the present invention is a display unit film member used as a movable film member or a fixed film member of a movable film type display device, and is formed by folding a colored film in which at least a portion serving as a display unit is colored. Having a display portion and a supporting film portion formed, and having a surface resistivity of 1 × 10 ² to 1 × 1 on the supporting film portion.
A conductive layer of 0 ⁶ Ω / □ is provided.

FIG. 5 is a perspective view showing a structural example (101) of the movable film member of the display film member. The movable film member 101 is formed by bending a single seamless colored film into two parts and forming the movable display part 2 and the support film part 12. The angle between the movable display portion 2 and the support film portion 12 is set to about 90 degrees. A conductive layer 13 is provided on one surface or both surfaces of the supporting film portion 12 at an appropriate position, and the conductive layer functions as the movable electrode 10.

The bending angle between the movable display portion 2 and the support film portion 12 is set to an angle such that the movable display portion 2 can be inserted into and removed from the gap of the fixed display portion, and is usually about 90 degrees as shown in FIG. To be done. The height d of the support film is set to a pixel pitch of 10 in order to reduce the angular change of the movement of the movable display unit 2 to reduce the unevenness of the screen and to largely displace the movable display unit with a low applied voltage. It is preferably double or more. However, if the height d is too large, the thickness of the entire display device becomes large, which is also undesirable. The size of each part of the movable film member varies depending on the display device to be finally assembled, but in the present invention, the width a of the movable display part is in the range of 0.1 to 50.0 mm, and the length b of the movable display part is 0. It is particularly preferably applied to a movable film member having a size in the range of 2 to 20.0 mm and the height d of the support film portion in the range of 0.5 to 50.0 mm.

A plurality of such movable film members for one pixel are arranged at a predetermined pitch so as to allow a slight gap in consideration of the pixel pitch, and are fixed using an adhesive tape. At this time, a conductive tape may be used to electrically connect the movable electrodes on the support film portion to each other.

As the colored film forming the movable display portion 2 and the support film portion 12, either a transparent or opaque film may be used depending on the design of the display device, but in the case of color display by color mixture, , Using a transparent film.

The colored film having a plastic film as the base material may be a single-layer film made of a colored plastic material in which a coloring material such as a pigment is mixed with plastic (that is, the base material itself is colored), or a similar colored plastic material. It is possible to use a coating film in which the surface of a plastic film is coated with a colored layer. The colored film used in the present invention only needs to be colored in at least the portion that becomes the movable display portion 2, but a colored film in which the entire film is colored can also be used without any problem. A colored film that is entirely colored does not require alignment for coloring, as compared with the case where a colored layer is selectively formed on only one side or both sides of the portion that becomes the movable display portion 2. It is easy to prepare and obtain from the market.

The single-layer colored film containing the coloring material can be obtained by mixing the coloring material in advance with the plastic material as a raw material and then forming a film. Examples of the coloring material include dyes, organic pigments and inorganic pigments, and pigments are preferably used from the viewpoint of light resistance. For the black film and the white film, a pigment having a high hiding property is preferable for obtaining a high contrast. Regarding other color films, those having high transparency are preferable in order to increase the color reproduction range when two or more color films are stacked. As the pigment, "Latest pigment application technology" issued by CMC Co., Ltd.
(Published in 1986, 1st edition, pp. 140-192)
Various pigments described in 1) can be used. Specific examples of preferable pigments include disazo yellow, brilliant carmine, phthalocyanine blue, carbon black and titanium oxide.

The thickness of the monolayer colored film is 1.0 to
It is preferably about 25.0 μm. In the case of a single-layer colored film, the amount of the coloring material added is mixed in the range of 1 to 50% by weight based on the total weight of the film. If the addition amount of the coloring material is less than the above range, it is difficult to obtain sufficient color development, and if it is more than the above range, film strength and flexibility are deteriorated. However, the appropriate addition amount also depends on the film thickness,
The transmission density of each color in the thickness of the substrate used is 0.2 to 2.
It is preferable to adjust the addition amount of the coloring material so that the reflection density in the final display image becomes 0.5 to 3.0 at a level of 0.

The coating colored film provided with a colored layer is a coating film in which a colored layer containing a coloring material and a binder as a main component is provided on one or both sides of a transparent substrate film (preferably a plastic film). . In particular, from the viewpoint of curl resistance, it is preferable to coat the colored layers so that both sides have substantially the same coating amount. As a preferable base film for the colored film, polyethylene terephthalate (PE) is used in view of heat resistance, dimensional stability, transparency and the like.
T) or a polyester film such as polyethylene naphthalate is used, and the thickness thereof is usually 1.0 to 30.0.
[mu] m, preferably from 1.5 to 20.0 [mu] m from the viewpoint of drivability and film strength. If the thickness of the polyester film is smaller than the above range, film breakage is likely to occur and dimensional stability is deteriorated, whereas if the thickness is larger than the above range, driving performance such as response speed and driving voltage deteriorates. As the coloring material for the coloring layer, the same coloring material as used for the single-layer coloring film can be used. Examples of the binder include uncured thermoplastic resins, thermosetting resins, and curable resins such as ionizing radiation curable resins. Above all, in order to obtain sufficient heat resistance against heating during bending and heat resistance capable of preventing sticking of films when the movable film member is incorporated in a display device and used at high temperature, the softening temperature is required. Or glass transition point is 100 ° C or higher, preferably 150 ° C
It is preferable to use the above binder. Here, the softening temperature is the softening temperature according to the measuring method according to JIS K-7196, and the glass transition point is the glass transition point according to the measuring method according to JIS K-7121.

By forming the colored layer of the colored film which constitutes the display film member used as the movable film member or the fixed film member described later, by using a binder having a softening temperature or a glass transition point of 100 ° C. or higher. The colored layer does not melt or soften even when the base film of the colored film is heated and softened for bending the display film member, so that the colored film can be prevented from sticking to the processing jig. . In addition, when the colored film constituting the display film member used as the movable film member or the fixed film member described later has a colored layer having high heat resistance as described above, the movable film mold obtained as the final product. Even if the display device is left at the ambient temperature, the film rigidity and the surface tack of the display portion are unlikely to change, so that stable drive characteristics can be obtained.

As the binder having a heat resistance of a softening temperature or a glass transition temperature of 100 ° C. or higher, a thermoplastic resin or a reaction curable resin such as a thermosetting resin or an ionizing radiation curable resin is suitable. You can choose a different binder resin.
Specifically as a thermoplastic resin that can be used as a binder,

Examples thereof include polyvinyl alcohol resins, polyamide resins, polyimide resins, polynorbornene resins, and mixtures, modified products, copolymers, and the like of the exemplified resins. Among these thermoplastic resins, polyarylate resin, polynorbornene resin, chlorinated polypropylene resin, and polyamideimide resin are particularly high in heat resistance, transparency, and solubility (soluble in organic solvents having relatively low boiling points). preferable.

As the thermosetting resin which can be used as the binder, a combination of a resin containing a reactive functional group and a heat-crosslinking type curing agent, for example, a polyol resin such as acrylic polyol, polyester polyol or polyurethane polyol, or a cellulose resin. And a cross-linked product (reaction-cured product) of an aromatic or aliphatic polyisocyanate resin. In particular, the one obtained by curing a polyol resin with an aliphatic isocyanate prepolymer has little yellowing due to ultraviolet rays, and is therefore suitable as a colored film for a display film member incorporated in an outdoor display.

Examples of the ionizing radiation curable resin that can be used as the binder include UV or electron beam curable resins, for example, UV curable materials such as UV curable acrylic monomers and oligomers.

Reaction-curable resins such as the above-mentioned thermosetting resins and ionizing radiation-curable resins are preferable because of their excellent adhesion to the base film.

When a non-curable resin is mainly used as the binder and the adhesiveness to the substrate is insufficient, adhesion of polyester resin, polyurethane resin, acrylic resin or the like to the extent that sticking or the like does not occur or You may add an adhesive resin.

The mixing ratio (weight ratio) of the coloring material and the binder in the colored layer may be in the range of coloring material / binder = 0.01 to 10.0, preferably 0.03 to 2. The range is 0. However, the appropriate blending ratio also varies depending on the thickness of the colored layer, and the transmission density of each color of the colored film on which the colored layer is formed is about 0.2 to 2.0, and the reflection density in the final display image. It is preferable to adjust the addition amount of the coloring material so that the amount becomes 0.5 to 3.0. In addition to the above, a dispersant, an ultraviolet protective agent, an antioxidant, etc. can be appropriately added to the colored layer. The thickness of the colored layer is usually 0.1

It is preferable to adjust the addition amount of the coloring material so that the reflection density in the display image is 1.0 to 2.5.

In the coloring layer of the coloring film, the above-mentioned coloring material, binder and, if necessary, other components are dissolved or dispersed in an appropriate solvent such as methyl ethyl ketone, ethyl acetate, toluene, water or alcohol. To prepare a coating solution, apply the obtained coating solution on the surface of the substrate film, dry it, and further, if necessary, perform reaction curing to form the coating solution.

An anti-curl layer may be provided on the colored film. The anti-curl layer can be formed using the same resin as the thermoplastic resin or thermosetting resin used as the binder, and usually has the same thickness as the colored layer on the back side of the colored film. Set up.

O₂(Sb-doped), In₂O ₃(Sn-doped), ZnO
(Al-doped) and the like.

As the conductive coating type particles, for example, various particle surfaces of titanium oxide (spherical or acicular), potassium titanate, aluminum borate, barium sulfate, mica, silica, etc., such as SnO ₂ (Sb-doped) are used. Examples thereof include conductive particles coated with a conductive agent.

Among them, π-conjugated conductive polymers (particularly polythiophene-based conductive polymers) and carbon-based particles from the viewpoints that they are relatively easy to be made into ink, have good coating suitability, and exhibit high conductivity even in a thin film. , In ₂ O ₃ (Sn
Dope) is particularly preferred.

As the particle diameter of the conductive particles, those having a particle diameter in the range of about 0.01 to 30.0 μm can be used. Examples of the particle shape include spherical particles, acicular particles, and scaly particles.

As the binder for the conductive layer by the coating method, a non-curing type thermoplastic resin, or a curing type resin such as a thermosetting resin or an ionizing radiation curing resin can be used. From the viewpoint of obtaining sufficient heat resistance against heating, and from the viewpoint of preventing sticking between films when the movable film member is incorporated in a display device and used in a high temperature environment, the softening temperature or glass transition. It is preferable to use a binder having a point of 100 ° C. or higher, preferably 150 ° C. or higher. When the conductive layer is formed by the coating method, the softening temperature or the glass transition point is 100 ° C.
By using the above binder, even when the film is heated and softened for bending the movable film member, the conductive layer on the surface thereof is not melted or softened, so that the film can be used as a processing jig. It can prevent sticking.

If the conductive layer, which is the movable electrode of the movable film member, is formed by a coating method and has high heat resistance, the movable film type display device obtained as the final product. Even if the film is left at the ambient temperature, changes in film rigidity and surface tack of the display portion are unlikely to occur, so stable drive characteristics can be obtained.

As the binder having a heat resistance of a softening temperature or a glass transition temperature of 100 ° C. or higher, a thermoplastic resin or a reaction curable resin such as a thermosetting resin or an ionizing radiation curable resin is suitable. You can choose a suitable binder. Specifically, the same as those exemplified above can be mentioned.

The blending ratio (weight ratio) of the conductive material and the binder in the conductive layer may be in the range of conductive material / binder = 0.01 to 20.0, preferably 0.05 to 5 The range is 0.0. However, the appropriate mixing ratio varies depending on the thickness of the conductive layer, the base film used, and the like, and cannot be generally stated. For example, when the conductive layer is directly provided on the polyester film base film, Surface resistivity is 1 ×
The amount of the conductive material is adjusted so as to be in the range of 10 to 1 × 10 ⁶ Ω / □.

The thickness of the conductive layer is usually 0.001 to
It may be about 30.0 g / m ² , and especially 0.01 to
It is preferably 5.0 g / m ² . If the film thickness is too thin, sufficient conductivity will not be obtained, and if it is too thick, the driving voltage will be high due to the weight of the movable film being increased, and a step will be seen in the pixel due to the wide distance between the movable films. Such problems occur.

The conductive layer formed by the coating method contains the above-mentioned inorganic conductive particles, a binder and, if necessary, other components.
A conductive ink is prepared by dissolving or dispersing in a suitable solvent such as methyl ethyl ketone, ethyl acetate, toluene, water, alcohol, etc., and the obtained conductive ink is applied to the surface of the supporting film by a gravure printing method, a screen printing method or the like. It can be formed by coating and drying by a vacuum process, and further by reaction curing if necessary. Conductive ink, the coating amount when dried on the outermost surface of one or both sides of the support film,
It is preferable that the amount of the conductive material be adjusted so that the surface resistivity of the support film is 1 × 10 ⁶ Ω / □ or less by coating the coating film at 0.01 to 5.0 g / m ² .

On the other hand, the conductive layer formed by the vapor deposition method is composed of a vapor deposited film of a conductive substance formed on the colored film.

Specific examples of the conductive substance include simple metals or alloys of aluminum, copper, gold, silver, nickel, chromium, iron, molybdenum, titanium, tungsten, tantalum, or tin-doped indium oxide (IT).
Although metal oxides such as O) can be used, among them, aluminum is particularly preferable because the vapor deposition temperature is relatively low.

The conductive layer formed by the vapor deposition method may be formed by depositing the above-mentioned conductive material in a predetermined pattern on a portion of the colored film, which will be the support film portion, or by depositing it on the entire surface of the colored film. The conductive layer is formed into a predetermined pattern by removing the vapor-deposited layer in the portion to be formed. In the case of vapor deposition in a pattern, vapor deposition is performed using a mask that covers the non-vapor deposition region of the display unit.

In the case of removing the vapor deposition layer to form the conductive layer in a predetermined pattern, after forming the metal vapor deposition layer on the entire surface of the colored film, a protective film is printed on the portion to be the support film portion to display. Do not provide a protective film on the part that becomes the part,
The conductive layer can be formed in a pattern by washing the vapor-deposited layer with water or dissolving and removing it with an acid or an alkali. In addition, a conductive layer can be formed in a pattern by providing an easily removable layer such as an aluminum layer on a portion to be a display portion and then providing a vapor deposition layer on the entire surface and then removing the easily removable layer.

The thickness of the conductive layer is usually 50-100.
It may be about 0Å, and particularly preferably about 100 to 500Å.

The display film member (movable film member and fixed film member) is obtained by cutting a colored film provided with a conductive layer into a predetermined size and shape as required.

The display film member obtained as described above has a thickness of about 90 by a heating folding jig in which the tip of the display portion of the colored film is sandwiched between heatable metal plates. The display part and the support film part are defined by bending at an angle of 10 degrees and heat setting. The heating temperature at this time varies depending on the type of the display film member used, the softening temperature and the processing jig, but is usually 100 to
Heat setting is performed by pressing for about 1 second to 30 minutes at about 300 ° C.

The display film member may have a shape other than a rectangle. FIG. 8 is a perspective view showing another example (102) of the display film member (movable film member and fixed film member) according to the present invention. Display film member 1
Reference numeral 02 denotes a comb-like shape in which a plurality of pixel units each including the display unit 1 or 2, the support film unit 12, and the movable electrode 10 or the fixed electrode 11 on the surface of the display unit 1 or 2 are connected via the connecting unit 17. A rigid base support 19 is attached to the base portion 18 of the support film portion 12 and the continuous portion 17 near the base portion, thereby reinforcing the base portion.
The display part 1 or 2, the supporting film part 12, the continuous part 17 and the base part 18 are cut out from one film having the conductive layer 13, and the conductive layer 13 functions as a fixed electrode or a movable electrode and is connected. The parts 17 are electrically connected to each other and function as a signal line for controlling the driving of each pixel.

The conductive layer 13 may be formed in a stripe pattern that traverses the support film portion 12 as shown in FIG. 8a, or as shown in FIG. 8b, a connecting portion below the base portion 18 of the support film portion 12. The conductive layer 13 may be provided up to 17. The conductive layer is formed so as not to extend to the display portion so as not to impair the display function.

The display section film member 102 is obtained by cutting out the display section 1 or 2, the support film section 12, the continuous section 17 and the base section 18 from one sheet of film material.
Are arranged side by side, and a plurality of such display unit film members 102 are arranged in parallel (not shown) and used. When the display unit film member 102 is used only as a movable film member, the fixed electrode 11 is arranged at a position facing the support film unit in the gap. The display film member 102 of these examples has high productivity because it does not require the labor of connecting a plurality of display film members for one pixel unit.

Next, a method of manufacturing the display film member according to the present invention will be described. The method for manufacturing a display film member according to the present invention includes a step of forming a conductive layer on a portion of a colored film in which at least a portion to be a display portion is colored, a step of forming a conductive layer on the portion to be a support film portion, and displaying by bending the colored film. Section and a step of defining the support film section.

As the colored film according to the present invention, as described above, a single layer film made of a colored plastic material in which a coloring material such as a pigment is mixed with plastic (that is, the base material itself is colored), or a similar film A coating film in which a colored plastic material is coated on the surface of a plastic film to provide a colored layer can be used.
As the colored film, a monolayer film in which the whole is colored and a colored coating film are easily prepared and available, and can be used in the present invention without any problem.

First, the step of forming a conductive layer will be described.
By forming a conductive layer in a predetermined pattern on one surface or both surfaces of a region serving as a support film portion of a colored film and cutting the conductive film, a conductive film functioning as an electrode is produced to form a display film member provided in the support film portion. be able to.
In particular, the conductive layer is formed in a stripe pattern on one side or both sides of the region to be the support film portion on the colored film,
By cutting, it is possible to produce a display portion film member including a striped electrode that crosses the body portion of the support film portion.

When the conductive layer is formed in a stripe pattern on the colored film, as shown in FIG. 9a, the conductive layer may be formed on the entire surface of the portion to be the supporting film portion, or as shown in FIG. 9b. In addition, a conductive layer may be formed on a part of the portion that becomes the support film portion. Furthermore, the conductive layer is
As shown in FIG. 10a, it may be formed in a stripe pattern of one row or two or more rows in the longitudinal direction of the long colored film, or as shown in FIG. 10b, in the lateral direction of the long colored film. May be formed in a stripe pattern of one row or two or more rows. Further, the predetermined pattern of the conductive layer may be formed in the same pattern on the front and back surfaces of the colored film, at positions facing each other.

The conductive layer may be formed by applying a conductive ink containing inorganic conductive particles and a binder to the surface of the support film portion of the colored film, or by forming a conductive material by a vacuum process. It may be formed by vapor deposition.

The coating process does not require the high temperature conditions as in the case of forming a vapor deposition film of a conductive substance by a vacuum process, so that the support film is less likely to undergo heat shrinkage or film breakage, and in the case of a vacuum process. Since the manufacturing cost is lower than that of, the coating method is more preferably used. Further, in the case of the coating method, as shown in FIGS. 9a and 9b, it is possible to form a conductive layer on one side or both sides while feeding a long colored film from a roll, so that continuous production can be performed at high speed. it can. Examples of the coating method include various methods such as gravure coating, roll coating, dip coating, spin coating, and screen printing, and among them, alignment when forming in the same pattern on both sides of the colored layer facing each other. High accuracy,
Gravure coating, roll coating, screen printing and the like are particularly preferable in that they can be easily wound in a long length.

In the present invention, in order to form the conductive layer by the printing method, the inorganic conductive particles, the binder and, if necessary, other components may be appropriately added such as methyl ethyl ketone, ethyl acetate, toluene, water and alcohol. A conductive ink is prepared by dissolving or dispersing in a solvent, and the conductive ink obtained is gravure-printed, screen-printed, etc. in a predetermined pattern as described above on the portion to be the support film portion of the colored film. Is applied by a non-vacuum-based process, followed by drying and, if necessary, reaction curing.

On the other hand, in the present invention, in order to form the conductive layer by vapor deposition, the conductive substance for vapor deposition is vaporized by the vacuum process as described above, and is attached and deposited on the surface of the colored film.

In order to selectively deposit a conductive layer having a predetermined pattern on one side or both sides of the portion of the colored film which will be the supporting film portion, it is necessary to deposit the conductive layer in the prescribed pattern on the portion of the colored film which will be the supporting film portion. Alternatively, the conductive layer is formed in a predetermined pattern by depositing the colored film on the entire surface and then removing the deposited layer in the portion to be the display portion. In the case of vapor deposition in a pattern, vapor deposition is performed using a mask that covers the non-vapor deposition region of the display unit.

When the vapor deposition layer is removed to form the conductive layer in a predetermined pattern, a metal vapor deposition layer is formed on the entire surface of the colored film, and then a protective film is printed on a portion which will be a support film portion to display. Do not provide a protective film on the part that becomes the part,
The conductive layer can be formed in a pattern by washing the vapor-deposited layer with water or dissolving and removing it with an acid or an alkali. In addition, a conductive layer can be formed in a pattern by providing an easily removable layer such as an aluminum layer on a portion to be a display portion and then providing a vapor deposition layer on the entire surface and then removing the easily removable layer.

When the conductive layer is formed in a striped pattern on a long colored film, a cutting step is required later. For example, in the case of manufacturing the movable film member 101 shown in FIG. 5, as shown by the alternate long and short dash line in FIGS.
When manufacturing the display unit film member 102 shown in FIG. 8, the display unit film member 102 is cut into a comb shape. The cutting can be performed by a method such as punching using a laser beam or a mold.

Next, the process of bending the colored film to define the display portion and the support film portion will be described. For example, in the case of manufacturing the movable film member 101 shown in FIG. 5, a single strip of colored film having a conductive layer is simply cut into strips each having a length of one pixel, and then the display portion of the colored film is formed. The tip portion of the portion is bent by a heating folding jig such that it is sandwiched by heatable metal plates, and is bent at an angle of about 90 degrees and heat set to define the display portion. The heating temperature at this time varies depending on the type of the display film member used, the softening temperature and the processing jig, but is usually about 100 to 300 ° C., and the jig is pressed against the film for about 1 second to 30 minutes. Heat set.

Further, the display film member 1 shown in FIG.
In the case of producing 02, a rigid base support 19 is attached to a single colored film on which a conductive layer is formed, and cut into a comb shape. By a heating folding jig that is sandwiched between heatable metal plates, it is bent at an angle of about 90 degrees and heat-set to simultaneously define each display unit. The heating temperature at this time is
Although it depends on the type of the display film member used, the softening temperature and the processing jig, it is usually about 100 to 300 ° C., and the jig is pressed against the film for about 1 second to 30 minutes for heat setting.

The order of the cutting step and the step of bending the colored film to define the display portion and the support film portion is arbitrary, and if possible, either step may be performed first. That is, after the step of forming the conductive layer, a step of defining the display portion and the support film portion may be performed, and thereafter, cutting into a predetermined shape may be performed.

[0108]

As described above, according to the display portion film member and the method of manufacturing the same according to the present invention, one seamless colored film is bent to be divided into two, and the display portion and the support film portion are divided. Is formed. Therefore, the step of adhering the colored film and the supporting film, which is required when the colored film and the supporting film are separately manufactured, is not necessary. As a result of eliminating the need for a bonding step that causes a poor yield due to extremely high precision, a display film member with an improved yield can be obtained.

Further, in the present invention, when the conductive layer is produced by the coating method, it does not require the high temperature conditions as in the case of forming the vapor-deposited thin film by the vacuum process, so that the support film causes heat shrinkage or film breakage. In addition to being difficult, the manufacturing cost is low compared to the vacuum process. Further, in the case of the coating method, the etching step required when the conductive layer is vapor-deposited on the entire surface of the film is unnecessary, the colored film is not exposed to the etching solution, and the deterioration of the film can be prevented. Further, even when the conductive layers are formed in the same pattern on both sides of the film, the alignment of the patterns is easy. Also,
Since it is possible to form a conductive layer on one side or both sides of a long colored film while unrolling it from a roll, continuous production can be performed at high speed. In addition, when the top coating method is used, it is possible to use a resin with high heat resistance as a binder, and in that case, it is possible to prevent film fusion to the heating jig when folding the movable film member. Further, when the movable film display device is used in a high temperature environment, sticking of the film can be prevented. Therefore, the yield at the time of production is further improved, and the movable film member and the movable film display device which are excellent in driving stability and environmental suitability can be obtained.
