Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal panel having a structure suitable for displaying advertisements such as messages, warnings and pop-ups. More specifically, at least the substrate on the side opposite to the viewing side of the liquid crystal panel is a plastic substrate, and a pattern is drawn on the outer surface of the plastic substrate with a reactive curable ink layer. The present invention relates to a liquid crystal panel capable of displaying advertisements such as messages, warnings and pop-ups, and a liquid crystal advertising medium using the same.

[0002]

2. Description of the Related Art Typical conventional advertising media are:
Printed materials such as posters and stickers can be mentioned, but they were not necessarily eye-catching because the display contents themselves did not change. In addition, there is a method in which a light-emitting element such as a light bulb or a light-emitting diode is turned on or blinked to attract attention, but there is a problem that power consumption is high.

If a liquid crystal panel is applied to the advertising medium, the display contents can be arbitrarily changed, and it is possible to meet the demand for attention. However, on the liquid crystal panel substrate,
If a glass substrate is used, the advertising medium may be damaged due to a sudden accident or the like, and the glass used for the substrate may be scattered to damage the human body. At that time, if the victim proves the defect of the advertising medium by the Product Liability Law (PL Law) and develops into a litigation problem or the like, the manufacturer side will bear a great burden.

Therefore, in Japanese Unexamined Patent Publication No. 8-15665, ON / O in which the intermediate color is not displayed by statically driving the display unit
There has been proposed a liquid crystal advertising medium that enables pop-up display by combining a plastic liquid crystal panel controlled by FF drive and a pattern layer drawn by printing. The liquid crystal panel configuration and the advertisement display function will be described with reference to FIG.

FIG. 11 is a view showing a liquid layer advertising medium in the prior art. The liquid crystal advertising medium 51 has a constitution of a plastic liquid crystal panel 53 in which transparent electrodes 13 and 14 in the shape of whole panel electrodes are formed on the inner surfaces of the first transparent substrate 11 and the second transparent substrate 12, respectively. A film-like sheet 55 on which a pattern layer is printed is attached to the front surface or the rear surface thereof via an adhesive layer 57, and a reflecting plate 59 is arranged on the rearmost surface thereof.

The pattern layer is drawn on a film-shaped plastic substrate for an overhead projector (OHP) by using a copying toner, a magic ink or the like.

When the pattern layer is arranged on the back surface of the liquid crystal panel 53, the liquid crystal advertising medium 51 turns on / off the liquid crystal panel.
By turning off, the pattern layer can be pop-up displayed on the display unit of the liquid crystal panel. Further, when the symbol layer is arranged on the front surface of the liquid crystal panel 53, it is possible to make the viewer recognize the symbol layer while blinking the display portion of the liquid crystal panel corresponding to the back portion to attract attention. .

[0008]

However, in the liquid crystal advertising medium 51, the copying toner, the magic ink, etc. improve the wettability of the ink on the general commercially available OHP film sheet 55. Therefore, the pattern layer can be fixed to the film-like sheet 55. However, it cannot be directly printed and fixed on a plastic film for a liquid crystal panel (hereinafter, referred to as a liquid crystal film).

That is, many films such as a gas (oxygen or water vapor) barrier layer for ensuring reliability and an easy-slip treatment layer for preventing static electricity and preventing adhesion between films are necessarily formed on the surface of the liquid crystal film. Because it is done. Since these films are formed of a hydrophobic substance having a large surface energy, it goes without saying that the toner for copying and the magic ink cannot be stably fixed on the liquid crystal film subjected to the above treatment. is there.

Therefore, a liquid crystal advertising medium is constructed by drawing a pattern layer on the film-like sheet 55 which is separate from the liquid crystal panel and overlapping the liquid crystal panel. As described above, the configuration in which the separate film-like sheet 55 is provided has a large number of members, and there is a problem in fixing the ink only by printing on the film-like sheet 55, which lacks reliability in long-term use. It was Therefore, it is not preferable to use this structure for the liquid crystal advertising medium.

Further, since the electrodes to be driven are all-surface electrodes, all of the characters to be written (corresponding to the pattern layer) are displayed in a pop-up, or the liquid crystal panel 53 located behind the characters to be written is blinked. I can't do it one by one
It is not possible to emphasize the advertising property by displaying the three letters or marks individually. Further, since the liquid crystal panel 53 and the separate film-like sheet 55 are stacked to form the liquid crystal advertising medium 58, the film-like sheet 55 and the adhesive layer 57 are interposed between the liquid crystal panel and the pattern layer. As a result, the amount of transmitted light is reduced and light is scattered, so that a clear display cannot be made, which is insufficient for public notice display that attracts attention.

Furthermore, if even one conductive dust enters the panel, the voltage drop or short circuit occurs due to the shape of the panel entire surface electrode, and the voltage leaks.
The liquid crystal does not receive enough voltage, and defective lighting is likely to occur.
Further, since it is not possible to identify the short-circuited portion of the full-surface electrode, it is very difficult to repair the portion and regenerate the panel.

An object of the present invention is to solve the above problems and to provide a novel liquid crystal panel which is thin and hard to break, and which can display a message, a warning, a pop-up display or the like composed of clearer letters and patterns. The purpose of the present invention is to provide a liquid crystal advertising medium that is equipped with the liquid crystal panel and can make a strong impact on the viewer.

[0014]

In order to solve the above-mentioned problems, the present invention adopts the following technical constitution.

That is, the first means for solving the above-mentioned problems in the present invention is to provide first and second transparent substrates on the inner surfaces of the first transparent substrate and the second transparent substrate that sandwich the liquid crystal. A liquid crystal panel provided with electrodes, wherein at least a first transparent substrate is a plastic substrate whose surface is covered with a gas barrier layer and a slippery treatment layer, and further reactive curing is applied to the outer surface of the first plastic substrate. That is, the mold ink layer is formed.

According to a second means, a desired pattern is formed on the first transparent electrode, and the pattern of the second transparent electrode is the same or more than that corresponding to the first transparent electrode pattern. Is to be formed in a large pattern.

Further, in a third means, the reactive curable ink layer is composed of a material containing a reflective metal and a resin component whose curing is accelerated by heat, and the ink layer comprises:
A fourth means is that the reactive curable ink layer is made of a material containing a pigment and a resin component whose curing is accelerated by ultraviolet rays, and absorbs a specific wavelength of light. However, it has a function of reflecting other wavelengths. A fifth means is that the liquid crystal is composed of a polymer network type liquid crystal material.

A sixth means is a liquid crystal advertising medium having a liquid crystal panel, and the liquid crystal panel is arranged such that the second plastic substrate is on the viewing side.

[0019]

DETAILED DESCRIPTION OF THE INVENTION

The structure of the liquid crystal panel of the present invention will be described below with reference to the drawings. FIG. 1 is a structural sectional view of a liquid crystal panel in which a reactive curable ink layer according to the present invention is arranged outside a polymer network type liquid crystal panel. It should be understood that the present invention is applicable not only to the polymer network (hereinafter, referred to as PN) type liquid crystal panel but also to liquid crystal panels having other configurations.

The liquid crystal panel 1 of the present invention is surrounded by the sealing material 17, and the beads 32 for evenly forming the cell gap.
The first transparent substrate 11 made of a plastic material for sandwiching the PN liquid crystal 19 dispersed therein and the second transparent substrate 12 made of a plastic or another material have first and second inner surfaces.
The transparent electrodes 13 and 14 are formed on the panel. A first lead-out electrode 15 is formed from the first transparent electrode 13 so as to extend on the first transparent substrate, and a conductive adhesive inside the sealing material 17 is formed from the second transparent electrode 14. The second extraction electrode 18 is provided to the first transparent substrate 11 via the material 16, and the reactive curable ink layer 20 is formed on the outer surface of the first transparent substrate.

The liquid crystal panel 1 includes a first transparent substrate 1
In addition to 1, it is preferable to use a plastic substrate for the second transparent substrate 12. This is because when the liquid crystal panel of the present invention is used as a liquid crystal advertising medium or the like, the liquid crystal panel 1 is exposed in front of the public, so it is preferable not to use glass or the like, which is a material that is easily damaged. is there.

The liquid crystal panel 1 is preferably a PN type liquid crystal panel. This is because the PN type liquid crystal panel is not suitable for high resolution display, but has a structure effective for a panel that does not require intermediate color display for turning on / off the entire surface electrode or an electrode pattern of an arbitrary shape by static driving. Further, the PN type liquid crystal panel does not need a polarizing plate and has an advantage that the thickness of the liquid crystal panel itself can be reduced.
Therefore, it can be said that the PN type liquid crystal panel is suitable as a liquid crystal advertising medium when a liquid crystal panel is applied to the liquid crystal advertising medium and a rough display such as a pop-up display that attracts attention is made.

Next, the means for impressing the viewer more strongly on the liquid crystal panel 1 used as the liquid crystal advertising medium will be described. Not only is it possible to draw characters or designs directly on the back surface of the liquid crystal panel 1 so that the liquid crystal panel 1 on which the entire surface electrodes are arranged may or may not be seen like a liquid crystal shutter, but the characters and patterns are also applied to the electrodes of the liquid crystal panel 1. By arranging electrode patterns such as, and coating the reactive curable resin layer 20 corresponding to the characters and patterns on the back surface of the substrate, a clearer display is possible and a strong impression can be given to the viewer.

That is, when a voltage is applied to the place where the transparent electrode pattern is present in the panel, light is transmitted and the reactive curable ink layer 20 formed on the back surface of the first transparent substrate 11 is formed.
Can be recognized by the viewer. However, since light does not pass through and is scattered in a place where there is no transparent electrode, the reactive curable ink layer 20 disposed on the back surface of the substrate cannot be recognized. As described above, the liquid crystal panel 1 of the present invention enables a clear display by combining the reactive curable ink layer 20 having the electrode pattern, the reflection function and the color. Further, if the reactive effect type ink layers 20 of different colors are formed in accordance with the respective character / design patterns,
A more emphasized display is possible.

A specific structure of the electrode pattern will be described below with reference to FIG. FIG. 2 is a panel plan view for explaining an example of an electrode pattern on the first transparent substrate 11 made of the plastic substrate used in the embodiment of the present invention. In this panel, in addition to the character / design pattern 21, the number pattern of the seven segment pattern 22 is added,
It has a structure that incorporates the amount display function, clock, and counter function, and the panel can be applied as a public notice display. Further, since each pattern is formed with the separate routing lines 23a and 23b for each block to be displayed, the respective patterns can be displayed separately on the panel.

Further, if the second transparent electrode 14 formed on the second transparent substrate 12 is formed on the upper surfaces of the wiring lines 23a and 23b formed on the first transparent substrate 11, respectively. When both electrodes are turned on, light is also transmitted to that portion for display. Therefore, the most preferable embodiment of the present invention is that the characters on both the first and second transparent electrodes 13 and 14 are
Electrode patterns corresponding to the pattern pattern 21 and the seven segment pattern 22 are formed, and the lead lines 23a and 23b are not displayed. The electrode pattern configuration will be described with reference to FIG.

FIG. 3 is a perspective view for explaining the relationship between the reactive curable ink layer pattern of the present invention and the transparent electrode pattern. “A”, “ka”, and “o” shown in the figure are examples of patterns for explaining the shape of the electrode pattern,
It is not particularly limited to this.

First transparent electrode 1 on first transparent substrate 12
In FIG. 3, the patterns of “a”, “ka”, and “o” and the wiring lines 23a and 23b for driving the respective patterns,
It is formed independently of each character. Furthermore, the pattern dimensions of the first and second transparent electrodes 13 and 14 may be the same, but the second transparent electrode 14 pattern located on the viewing side is slightly larger than the first transparent electrode 13 pattern. It is preferably formed. Even if the viewer sees it from different directions, the characters and
This is because the pattern can be recognized.

Further, the first transparent electrode 12 pattern has separate wiring lines 23a and 23b for each character and pattern, but the second transparent electrode 13 pattern character and
All the drawing lines 24 of the design may be connected together.
With this configuration, it is possible to control the lighting of each character independently, and the wiring line 23 from the character can be used.
Since a, b, and 24 can be arranged so as not to overlap with each other on the upper and lower substrates when viewed from the viewing side, they are not reflected on the liquid crystal panel. Therefore, only the characters to which the voltage is applied to the electrode pattern can be clearly displayed.

With the above configuration, each character can be driven independently, and each "A", "ka", and "O" character can be made to blink independently. Only the design can be displayed clearly.
Further, a reactive curable ink layer 20 corresponding to each pattern is arranged on the back surface of the first transparent substrate 11, and its color is changed to a different color for each of the letters "a", "ka", and "o". By changing it, it becomes possible to further emphasize the advertising property. Further, by forming an electrode pattern as shown by “o” in FIG. 3, it is possible to display hollow characters. Needless to say, it is also possible to form the reactive curable ink layer 20 on the entire surface of the substrate and display and specify each character / design in a single color.

Next, the reflective curable ink layer 20 which can be directly printed on the plastic substrate will be described. First,
A case where a thermosetting ink having a reflecting function is used for the reactive curable ink layer will be described. This thermosetting ink is formed by mixing a small amount of silver powder or aluminum powder. The resin component is a vinyl chloride resin, an acrylic resin, an acrylic resin having a urethane bond, or a copolymer resin of vinyl chloride and vinyl acetate, and among them, a copolymer resin of vinyl chloride and vinyl acetate is preferable. This is because the concentration can be easily adjusted from the molar ratio of both resins and the degree of polymerization. For example, increasing the proportion of vinyl chloride improves chemical resistance and film strength, and increasing the proportion of vinyl acetate improves solubility, flexibility, and adhesiveness. Can be specified. Therefore, when the reactive curable ink mixed with the resin is used, the gas barrier layer, the liquid crystal film on which the slipperiness-treated layer is formed,
The reactive curable ink layer 20 can be reliably fixed in a stable state.

As described above, since the heat ray curable ink layer having a reflection function can be applied to the outside of the first plastic substrate by a well-known screen printing method and cured at a low temperature, it can be cured as in the prior art. A new component (film-like sheet 55) other than the liquid crystal panel and an adhesive layer 57 for attaching it are unnecessary. Further according to the invention,
Since it is possible to print directly on the back of the liquid crystal film substrate,
Since only the first transparent substrate 11 is provided between the ink layer and the transparent electrode, it is possible to display clear reflected characters.

Next, the case where the ultraviolet curable ink having a function of absorbing a specific wavelength of light and reflecting other wavelengths is used for the reactive curable resin layer 20 will be described. This ultraviolet curable ink is an acrylic resin having photosensitivity or an epoxy acrylate resin having photosensitivity, and among them, an acrylic resin having photosensitivity is preferable. This ultraviolet curable ink is a resin component whose curing is accelerated by ultraviolet rays, for example, phthalocyanine for blue,
Chlorinated copper phthalocyanine is used for green, and organic pigments such as quinacridone are used for red. This can be printed and cured on the outside of the first transparent substrate 11 by the above method, and the reactive curable ink layer 20 can be reliably and stably fixed to the liquid crystal film.

Further, it is possible to easily perform multicolor printing of characters, patterns, etc. drawn with color inks of different colors arbitrarily selected at desired positions on the back side of the first transparent electrode 11 of the plastic substrate. , It becomes possible to display with a higher advertising property.

A twisted nematic liquid crystal may be used for the liquid crystal panel 1. The difference from the PN type liquid crystal panel is that the first and second electrode patterns are formed in a matrix shape, that a twisted nematic type liquid crystal is used for liquid crystal molecules, and a retardation plate and a polarizing plate are provided. That is the point. With this configuration, fine display by matrix display is possible, and display quality of the panel can be improved. However, since there is a problem that the thickness of the panel itself becomes larger than that of the PN type liquid crystal panel, it is only necessary to properly use the liquid crystal panel according to the application and configure the liquid crystal advertising medium.

(Example) Next, a method for manufacturing a PN type plastic liquid crystal panel having a reactive curable ink layer of the present invention will be described with reference to the drawings. 4 to 9 are process cross-sectional views showing the method for manufacturing the PN type plastic liquid crystal panel used in the examples. 4 to 5, only a portion corresponding to one cell is shown, but in the following manufacturing process, it is confirmed that a large number of plastic substrates are used and a large number of these shapes are simultaneously formed on the same substrate. I want you to understand.

First, although not shown in the figure, a transparent electrode is formed on the first transparent substrate 11 which is a plastic substrate having a thickness of 0.1 to 0.4 mm by a low temperature sputtering method or a vacuum deposition method. A film is formed with a sheet resistance of -100Ω / □.
Thereafter, a photomask prepared in advance is used for the transparent electrode on the first transparent substrate 11, and a letter / design pattern or a seven segment pattern of a desired shape is formed by a photolithography / etching process. Further, the second transparent electrode 14 corresponding to the first transparent electrode 13 is formed in a predetermined pattern on the second transparent substrate 12 made of any one of the base materials. The plastic substrate used had a gas barrier layer and an easy-slip treatment layer formed on one of polycarbonate resin, epoxy resin, polyether sulfone resin, and acrylic resin.

Next, as shown in FIGS. 4A and 4B, a solvent volatilizing type JALS1024-R9 (JSR) is formed on the transparent electrode patterns of the first and second transparent electrodes 13 and 14.
Printed), and the alignment film 31 is printed using 90 ° C. to 120 ° C.
To cure. In the case of the PN type liquid crystal, this is performed in order to improve the uniformity of the wettability and the scattering property at the time of injecting the liquid crystal.

Next, as shown in FIG. 5A, a sealing material 17 is formed on the first transparent substrate 11 by using a thermosetting adhesive. Similarly, as shown in FIG. 5B, a conductive adhesive 18 is formed on the second transparent substrate 12 using Rexbond T-700 (manufactured by Toyo Ink Mfg. Co., Ltd.). Further, a gap material is applied to the second transparent substrate 12 by using a spacer sprayer of a dry method or a wet method, and beads 32 in which a plastic material having a sphere diameter of 7 μm to 10 μm is coated with an adhesive material for uniform cell gap are provided. Disperse at a rate of 150 to 200 pieces / mm ² . Then, the 1st transparent substrate 11 and the 2nd transparent substrate 12 are piled up, and a cell is completed. The cell gap at this time is 9 μm to 15 μm.

Next, as shown in FIG. 6, the cells 33 are
The dust-free paper 35 is inserted between the cells so that the cells 33 do not stick to each other due to heat, and the plurality of cells 33 are stacked and fixed by the jig shown in the figure. Next, 0.4 to 1.2 kg / cm is applied to the airbag 34.
Apply pressure of ² for 1 to 2 hours in the baking furnace 120 to 1
Sealing material 1 placed between the substrates by heating at a temperature of 60 ° C
Harden 7.

Next, before cutting the cell 33 taken out from the firing furnace into individual outer sizes, as shown in FIG. 7, the first transparent substrate 11 of the cell 33 is placed on the upper side, and the reactive curable ink layer is formed. 20 is printed with a predetermined pattern by a known screen printing method. The character / pattern pattern at this time is the first
When it is desired to emphasize the characters and patterns of the first transparent electrode 13 on the transparent substrate 11, the screen printing accuracy is taken into consideration, and the character outline of the first transparent electrode pattern is about 300 to 1000 μm.
The reactive curable ink layer 20 is formed by printing using a large screen mask 40. If you want to emphasize proper nouns, instructions, warning words, marks, symbols, etc., you can change them to different screen masks. Further, when the characters or patterns to be emphasized are arranged in almost the entire area of the liquid crystal display panel, screen printing may be performed in the same color on the entire back surface of the first transparent substrate 11.

Here, when the reactive curable resin layer 20 having a reflection function is formed, a specular ink silver No. 2 (Seiko. Co., Ltd.) which is a thermosetting ink based on an aluminum pigment and a small amount of vinyl chloride resin is used. (Advance)
Squeegee 41 with a screen mask 40 of 325 line / inch mesh.
Then, the reactive curable ink layer 20 having a reflective function can be formed by moving to 2 and printing. Further, in the case of forming a reflection film with higher performance, it is preferable to mix a small amount of silver powder with the thermosetting ink for printing.

Thereafter, the resin is heated at a temperature of 60 ° C. to 80 ° C. for about 20 minutes to 30 minutes to volatilize the solvent contained in the reactive curable ink layer 20 to cure the resin, and outside the first transparent substrate 11. Make sure that the silver color is fixed on.

When it is desired to arrange a specific color pattern, ultraviolet curable ink is printed on the outer surface of the first transparent substrate 11. For example, when printing red, UV curable ink UVA510 / American Red (Seiko
(Made by Advance) is used to print on the screen of the mesh 325. After that, about 2,000 nm of 365nm UV
By irradiating up to 3,000 mJ, the red color can be fixed on the outside of the first transparent substrate 11 substrate. Further, when it is desired to display another color, after the previously applied color is dried, another ink is printed with another pattern and the same method is used.
The transparent substrate 11 is fixed.

Next, although not shown in the figure, a single cell is punched into a predetermined size by using a Thomson blade according to the outer size of each cell.

Further, as shown in FIG.
In order to expose the external take-out terminal using, the extra portion of the second transparent substrate 12 is cut, and the plastic panel 2 is completed.

FIG. 9 is a structural plan view of a completed body of the liquid crystal panel 1 of the present invention. Next, the plastic panel 2
Using a vacuum injection method, PN liquid crystal PN-170 (manufactured by Dainippon Ink and Chemicals, Inc.) 19 is injected into the panel at 19 ± 0.5 ° C. At this time, the PN type liquid crystal 19 is a mixed liquid crystal precursor containing an organic monomer in the liquid crystal.

Further, after the PN liquid crystal 19 is injected, an acrylic ultraviolet curing adhesive 45 for closing the injection hole 44.
After being applied to the injection hole, the organic monomer and the sealing material in the PN liquid crystal 19 are simultaneously cured by irradiating with ultraviolet rays.
At this time, by irradiating about 3000 mJ of ultraviolet light having a wavelength of 365 nm, the organic monomer forms a solid substance in the liquid crystal as an organic polymer and also cures the sealing material. The liquid crystal panel 1 of the present invention is completed through the above steps.

Next, an example of the configuration of a liquid crystal advertising medium, which is an application example of the liquid crystal panel of the present invention, will be described with reference to FIG.
