Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a liquid crystal display device vC11 in which when the liquid crystal panel is illuminated from behind, the display section of the liquid crystal panel displays multicolor display in at least two or more colors.

In recent years, the application of liquid crystals has progressed, and twisted nematic (hereinafter referred to as T
As DT (hereinafter abbreviated as GH) (hereinafter abbreviated as I) liquid crystal display and DT (hereinafter abbreviated as GH) become available on the market, the demand for multi-color display has increased. This is the transmission m
The backlight is illuminated as necessary, and the display within the partition of the backlit liquid crystal panel is a multi-color display of at least two colors.

It is ideal for functional display, decorative effects, and various applications and usage development.

Conventionally, in order to display multiple colors, the polarizer l was made multicolored as shown in 111WIJ. , 12
It consists of 2 is an upper photon, 3 is an upper substrate, 4 is a lower base f, 5Fi spacer, 6 is a liquid crystal, and these are collectively called a liquid crystal panel, 8 is a semi-transmissive reflector or light scatterer, and 9 is a transmissive reflector or light scatterer. It is a light source for backlight. Liquid crystal 6 is TM liquid crystal and VcG1! There are liquid crystals, DτN liquid crystals, etc. In the case of GH liquid crystal, the lower polarizing plate 2 is omitted. Here, the case where the liquid crystal 6 is a TN liquid crystal will be explained as an example. b is a GH or DTM liquid crystal.
The same applies to the case of . The same applies to the description of the drawings below.

The light emitted from the light source 9 passes through a semi-transmissive reflector or light scatterer 8 and illuminates the liquid crystal panel 7. However, since the upper photon 1 of the liquid crystal panel is divided into three parts 10.11°12 and each part is composed of a polarizer of a different color,
．． Different colors appeared depending on the color of each polarizer.

However, in the conventional example shown in Fig. 111, Fi and polarizer l are divided into h parts (10, 11, 12)K.

Prepare 6 different colored polarizers IQ, 11.12.

A method of pasting them together was used. With this method, each polarizer 10, 11, 12 can be cut into an arbitrary shape! upper board 3
Generally, adhesive is used to bond the upper substrate 3 and the upper photon 1, but after applying the adhesive to the polarizer 1 and cutting it into an arbitrary shape,
Cutting out arbitrary shapes is not only unsuitable for mass production, especially for small batches, but also air bubbles in the adhesive layer at the edge of the cutout.
2-pronged or split polarizers 10, 11.1 are prone to uneven coating, peeling, and cracks on the edges of the polarizer itself.
When attaching 2 to the upper substrate 3, make sure that there is no space between them.
II! It was difficult to match and the yield was low or zero. Furthermore, it is difficult to obtain polarizers with various color characteristics. This means that the polarizer l is generally
The bottom is made by stretching a film such as P Mum and adsorbing bwt purple and other dyes, but due to the process of mass production of polarizers, it is difficult to produce polarizers with various color characteristics using a black cloth. Cos F high and 0. # [Crystal display devices have become extremely expensive. As explained above, the conventional polarizer l shown in Figure 1 is divided and pasted together.
It was extremely expensive and difficult to manufacture.

Diagram 2 Fi is an example of [2] of a conventional multicolor liquid crystal display device. In FIG. 2, the liquid crystal display device is explained as a transmission type G1111.
T violet! I! The same explanation applies to the 1st class. 13 is a polarizer, which is placed on the upper substrate 14. 15 is the lower substrate, 16 is a spacer, and the liquid crystal 17 is the spacer 1.
By 6, 1 is divided into 3 rooms, 18.19°20. 18.19.20 Each liquid crystal has a different color. The liquid crystal panel 21 is configured and discussed above. 2
2a is a transflective reflector or light diffuser, and is a 23ij light source. The light emitted from the light source is scattered by a semi-transmissive reflector or light diffuser 22, and illuminates the liquid crystal panel 21.

However, since the liquid crystal 17 is composed of three types of liquid crystals 1g and 19.20 which have different colors due to the spacer 16,
The light passing through the polarizing plate 13 exhibits different hues depending on where each liquid crystal 18, 19, 20 is housed.

In this case, since the spacer 16 falls within the display section, the width of the spacer allows the light emitted from the party source to be scattered by the semi-transmissive reflector or light diffuser 4 to be directly seen clearly, so the display is 1. The appearance is bad, and the inside shape of the spacer 16 is not necessarily straight.
The appearance of the display is poor because the K type is not released, and it is necessary to inject several types of liquid crystals 17 (in Figure 2, three types of 1g, 19, and 20), which causes problems in man-hour yield. Due to the design of the inlet, it is impossible to shape the bottoms of 18, 19, and 20 in any pattern in any part.

There were a number of problems.

The multi-color liquid crystal display device of the present invention overcomes the drawbacks of the conventional multi-color liquid crystal display device shown in FIG. This will contribute to expanding the field of application of liquid crystals.

FIG. 3 shows the first a of the multicolor display liquid crystal display device of the present invention.
It's a mistake. 24 is an upper photon, 25 is an upper substrate, 26 is a substrate, 27 is a lower substrate, 28 is an upper photon, 29 is a liquid crystal, and the liquid crystal panel 30 is composed of 11 or more.
Note that the liquid crystal panel 30 is.

Although the 1M type is shown in the figure, the same applies to GH type, DaM type, DiN dust, etc., and depending on the liquid crystal display method, the upper and lower polarizers 2
Although one or both of 4.28 may be absent, the same explanation as in this specification applies to FM.

There is no problem in explaining multicolor display due to differences in liquid crystal display methods. The same applies not only to FIGS. 1, 2, and 3, but also to the drawings illustrated and explained below.

31 is a semi-transmissive reflector or a light diffuser. 36 is a light source, and a dye element 32 is arranged between the semi-transmissive reflector or F1 element diffuser 31 and the light source 36. The pigment element 32 has multicolored color areas 33, 34, 35.

The dye elements must be translucent, excluding A3IM elements whose light is blocked by the dye element 32 and does not reach the liquid crystal panel 30. The meaning of translucency includes types that can reach the liquid crystal panel 30 even when dry, semi-transparent types such as 0 dye 32Fi, colored plastic films, various resins, plastic plates, and glass plates. In addition to bonding with the semi-transparent reflector or light diffuser 31, transparent ink with one color, lacquer 1 resin, adhesive, etc. are applied to the light source 36 side of the semi-transparent reflector or light diffuser 31. Spraying on the surface - Even if it is applied by dipping, printing, spinner coating, etc.
It is also possible to superimpose another color on a film, glass, etc. in an arbitrary part, or remove a color in an arbitrary part, resulting in two or more colors being released. Also 1 color element 32
The 0-divided parts 33, 34, and 35 are not integrated, but separate parts 1, for example, o1 inserted into each part. Even if each part has a different color, A0
Transflector or light diffuser 31Fi.

The liquid crystal panel 30 is illuminated by diffusing the light emitted from the light source 36 and passing through the single color element 32.

As a semi-transmissive reflector, there are semi-transmissive reflectors that are already commercially available and used in six types of liquid crystal display devices. It is reflective and uses 36 backlight sources in dark places.

It has transflective properties that illuminate the liquid crystal panel 30.

The light diffuser may be made of milky white plastic resin 1 such as milky white acrylic, milky white Delrin, milky white polycarbonate, milky white styrene, milky white plastic, milky white glass, milky white film, etc.

Colored materials such as milky yellow or milky blue that have light scattering properties can also be used. In any case, at least a portion of the display section of the liquid crystal panel 30 includes the 1-color element 32, which has light scattering properties and has the property that the light emitted from the light source 36 and passed through the 1-color element 32 is arranged. It's distributed as it should be. Pigment 3
2 is at least one color or more, and when the light emitted from the light source 36 passes through the color element 32 and illuminates the liquid crystal panel 30, [Illumination color-coded within the partition of the crystal panel 30 into at least two areas] will be done. Among the regions of at least two colors, the region of at least one color may be colorless. When all the light that illuminates the display section of the liquid crystal panel 30 is the source that has passed through the color element 32, the source that emitted the 1 color element 32Fi light source 36 is colored at least in one place, and the display section of the liquid crystal panel 30 is colored. The circle must be colored so that at least two or more color divisions can be created.At least one or more places in the area of two or more color divisions may be white, black, or gray. . Namely, among the colors in this specification.

Also includes white, black, and gray. Further, when the light illuminating the display parting area of the liquid crystal panel 30 does not entirely pass through the color element 32, but only a part of it passes through the color element 32, and the rest does not pass through the color element 32. , for example, the liquid crystal panel 3
If the color element 32 is arranged only in a part of the 0 display section, or if part of the 1 color element 32 is cut out, part of the light emitted from the light source 36 will pass through the color element 32. However, some of the light passes through the semi-transmissive reflector or light diffuser 31, but some of it does not pass through the color element 32, and even though it passes, part A and B are scattered by the light scatterer 31 without being colored, and are reflected on the liquid crystal panel 30. Two or more areas within a display partition are illuminated with different colors. In this case, if the dye element 32 is colored in at least one place with a color different from that of the light scattering element 31, including the case where the entire dye element 32 is colored, lu. As described above, the liquid crystal display device of the present invention (FIG. 3) is subjected to lateral pressure.

When constructed like this, the light emitted from the light source 36 is! 13.
The color-coded areas of the single color element 32 pass through the color-coded color element 32 at 34.35, are scattered by the light scatterer 31, and then illuminate the crystal panel 30.33.34.
Even if the boundaries of 35 have gaps due to printing or overlapping of one color, the light that is scattered and illuminates the liquid crystal panel 30 is the color element 32.
The boundaries between the color-coded parts 11, 33, 34, and 35 do not create gaps or overlap colors, resulting in unsightly lines.

Since the colors gradually become different Kf, beautiful colors are displayed. That is, unlike the conventional method of pasting together a plurality of polarizing plates as shown in FIG. Since there is no problem even if a gap is created, a multicolor liquid crystal display device is very easy to manufacture, and the yield rate is also improved. In addition, it was very difficult to cut and paste the polarizing plates, and to display the areas of the A and B colors, but with the liquid crystal display device of the present invention shown in Fig. 3, printing, casting, pasting, etc. are very difficult. Simple Mik
Manufactured with a yield of 4hL. We also have inks of various colors, adhesives, films, plastics, etc.

Not only can combinations of commonly used and commercially available colors be easily made, but also free color combinations can be easily, reliably, and inexpensively realized. In addition, to the human eye, it is natural for the boundaries on the color segments to change in an analog manner, and it is perceived as beautiful, but the conventional analog color boundaries shown in Figure 1 and Figure 2 have been completed. Boundary changes were realized easily, reliably, and inexpensively. In addition, each color liquid crystal of the conventional example shown in Fig. 2 is separated by 16 spaces,
Method #-1t of storing in each chamber, spacer 16 part is clearly visible.

Although it was unsightly, there is no need to worry about the liquid crystal display device of the present invention shown in No. 3 rp0J. In addition, when the spacer 16 is crushed, the crushed edge of the spacer 16 will not be jagged, the crushed edge will not be too large, too small, or waved. Since the structure with one color element 32 added may be used without changing the conventional structure, the reliability of the liquid crystal panel 30 and the ease of manufacturing are improved. In addition, since it is sufficient to add the dye element 32 in an extra row, if any error occurs in the manufacturing of the first dye element 32, only the first dye element 32 need be replaced. 7.2
Since 1 itself becomes defective, it is inexpensive as a whole and is easy to manufacture.

When the dye element 32 is integrated with a semi-transmissive reflector or a light scatterer 31 - for example, even when printed or pasted together, if the transflective type or light scatterer 31 is discarded, the price is generally low. This is very cheap compared to the price of the liquid crystal panel 30 itself, making it possible to produce a liquid crystal display device that is inexpensive overall. Also, the color combination is also the polarizing plate 1-? It was very difficult to manufacture the liquid crystal 17 shown in FIG. 2 in any color and required direct mounting, but the present invention can be manufactured at low cost. Furthermore, by replacing only the color element 32 without changing the liquid crystal panel 30, if the replaced color element 32 has a different color scheme than the one before replacement, the liquid crystal display can be easily and inexpensively reliably displayed in a different color scheme. The device can be realized. Also, it is easy to change the color pattern of the two-color element 32,
6 It meets the various requirements of various applications.

Furthermore, in the conventional examples shown in Figures 11 and 2, there are fine color patterns and color patterns.

Producing a dot or line color pattern has been very simple and expensive, but it can be easily realized with the liquid crystal display device of the present invention shown in FIG. In addition, when the IW crystal panel 3o is of a reflective type or a transflective type, and a backlight is not required in the daytime when a certain b is bright b under daylight, the 1-dye element 31 is a transflective reflector and an XFi element scatterer. For discussion, the light source 36 is placed under
Even if I erase A and L! ! Light received from above the crystal panel 30 is reflected by the semi-transmissive reflector or light scatterer 31, and the lighting state of the liquid crystal panel 30 can be clearly seen. In addition, in a dark place, when the light source 86 is turned on, the IL liquid crystal panel 30 changes to 1 color element 32 and displays 2 to 0 colors in different color lines, resulting in a beautiful display.In other words, a starry night display is possible. Under normal daylight conditions, the light source 36 can be set to a non-lit MIC mode, making it possible to reduce power consumption.

Under insufficient lighting, the light source 36 can be turned on to provide a richly colored display. Furthermore, the liquid crystal display device f of the present invention can display one color in the area within the partition of the liquid crystal panel 30.

It is possible to display the area within the section by function and to display the color for each function. Therefore, it is possible to provide an h display device that is easy to see and reduces the possibility of misreading the function display.

Diagram 4 is a second embodiment of the present invention. 37 is an upper polarizer, 38 is an upper substrate, 39 is a spacer, 40 is a lower base &, 41
42 is a liquid crystal, and from the above, the liquid crystal panel 4
3 are made up. 44 is a semi-transmissive reflector or light scatterer, which is a 47Fi dye element, and two color parts 45 and 46.
Release from the area. 48 is a light source. The color element 47 is large enough to cover the entire display section of the liquid crystal panel 43.
Or, there is no configuration, and a portion of the light emitted from the light source 48 is not colored by the color element 47, but is scattered upon hitting the tangent transflector or light scatterer 44, illuminating at least a portion of the display circle on the liquid crystal panel 43. do. The color element 47 emits at least one color different from the color of the transflector or light scatterer 44. The other configuration is the same as that described in the third embodiment of the present invention, @Fig. This has the advantage that the cost of materials can be reduced, and that the light intensity does not weaken because the curved portion that requires coloring does not pass through the color element 47. Generally, even if any of the 470 color regions 1545 and 46 of the color element is transparent, the transmission source strength will be lower by several to several tens of meters compared to before transmission, but there is no need to worry about that in Figure @4.

FIG. 5 is an embodiment of the invention shown in FIG. 49 is an upper polarizer, 50 is an upper substrate, 51 is a spacer, 52 is a lower substrate, 5
3 is a submerged photon, 54 is a liquid crystal, and the above constitutes a liquid crystal panel 55; 56 is a semi-transmissive reflector or light scatterer; and 62 is a light source. 61 is a color element, and a color area of 57.58.59.60 is left open. Of these, 5
9#'i is a through hole and is cut out! The shapes are manufactured by punching, press punching, heat cutting, two-removal molding, etc.

A portion of the light emitted from the zero light source 62, which can be any arbitrary shape such as a circle, an ellipse, or a square, passes through the majority of the color elements 59 and is not colored by the color element 61, but directly passes through the semi-transparent reflector or light scatterer 56. I won. Since the light is scattered and highlights at least a portion of the liquid crystal panel 55, this is the second embodiment of the present invention in terms of material cost and light transmission. The same effect as in Fig. 4 can be obtained. Other effects are the same as in the first embodiment of the present invention, FIG.

FIG. 6 shows a fourth embodiment of the present invention. 63 is the upper polarizer, 64Fi upper group 165t! Spacer, 66 is the lower substrate, 6
7#i lower polarizer, 68a liquid crystal, e70Fi semi-transmissive reflector or light scatterer that constitutes the liquid crystal panel 69, 76 is color area 71.72.73.74.75
It is a pigment composed of It is a 77Fi light source. The dye element 76 is directed to the surface of the light source 77 of the transflector or light scatterer 7o.

Printing with colored ink, resin, adhesive, lacquer, etc. There may be areas that are not colored and printed, such as 9 colored areas 73 consisting of 10 non-colored areas 73, or As shown in Figure 5, there may be no single color element, or there may be a through hole. In this manner, the same effect as explained using Figure 3 of the first embodiment of the present invention can be obtained. When printing on the lower surface of the semi-transmissive reflector or light scatterer 70 as shown in Fig. 6, it will be difficult to print one color element 76.

The number of parts is fewer than in the case of casting or bonding. i [There is an advantage that mutual alignment between the pattern of the crystal panel 69 and the pattern of the dye element 76 is easy and accurate. Furthermore, printing is a unique technology and is technically established. Suitable for low-cost mass production, color combinations are arbitrary and easy. It has the advantage of being able to print with fine precision, and of course the dye particles used for printing are transparent or semi-transparent, and the light source 77
The light emitted must pass through the single color element 76 and be scattered by the light scatterer 70 to illuminate the liquid crystal panel 69.
If there is an unintended printing gap or color area 71
Even if an unintended overlap of the printing occurs at the boundary between One-color areas 74 and 75 with no visible gaps or overlaps.
．． The boundary between 71 and 72 changes in an analog manner, producing beautiful multicolor colors that are clearly visible.The printing itself is therefore very easy to work with, mass production is easy, the yield is good, and the cost is low. Other effects similar to those shown in FIG. 3 can be obtained.

FIG. 7 shows a fifth embodiment of the present invention. 78 is an upper polarizer, 79#'i is an upper substrate, 80#'i is a spacer, 81 is a lower substrate, 82 is a lower polarizer, and 83i1 is a liquid crystal.

The liquid crystal panel 84 is constructed from the above. 85 is a semi-transmissive reflector or a light scatterer. Reference numeral 86 denotes a transparent, semi-transparent or semi-transparent reflective film (hereinafter abbreviated as a transparent film), on which a dye element 90 is printed. The color element 90 is divided into at least two color regions 87, 88, 89. There are 91 light sources. In this way, the transparent film 86 is thin and can be printed from a roll, making it suitable for mass production. Printing on the film 86 can be performed not only by screen printing, but also by gravure printing, etc., and can be produced in large quantities at a very low cost, and the printing accuracy can also be finer and more accurate. If the semi-transmissive reflector or light scatterer 85 is expensive, the semi-transmissive reflector or light scatterer 85 can be made by combining a transparent film 86 with dye particles 90 printed on it, which is very inexpensive compared to it.
The goal is to prevent costs from increasing due to printing errors on the top.

Note that one color element 90 is the liquid crystal panel 8 of the transparent film 86.
Even if you print it on 4@, it will be more than 1. Other mechanisms Fi Fig. 3 ~ @
It is the same as Figure 6. In addition to this, it has the effects shown in Figure 3.

Figures 1 and 8 show a sixth embodiment of the present invention, in which 692 is an upper polarizer, 93 is an upper substrate, 94 is a spacer, 95 is a lower substrate, and 9
6 is a lower polarizer, and 97 is a liquid crystal.

The liquid crystal panel 98 is constructed from the above. 99.100 is a semi-transmissive reflector or light scatterer, and 104 is at least two or more color regions; in this example, three color regions 101, 102;
．． It is a pigment element having 103-. 105 is a light source. The other configurations are the same as those shown in FIGS. 3 to 7. In this way, the light emitted from the light source 105't is colored by the vk1 dye element 104 scattered by the transflector or light scatterer 100, and further colored by the transflector or light scatterer 9.
9, the analog color change at the boundaries of each color area 101, 102, and 103 becomes noticeable.

In particular, there are unintended gaps in the boundaries between color areas 101 to 103,
When colors overlap, the inconvenience, unnaturalness, and discontinuity are less noticeable, and it is possible to realize a multicolor display with analog aesthetic changes. Other effects are similar to the embodiment shown in FIG.

FIG. 9 shows ft11! using a liquid crystal display device having the structure of the first to sixth embodiments shown in FIGS. 3 to 8 of the present invention.
This is an application example. The display functions are IARM, M, PM, hours and minutes, each with a different color backlight, and AL, RMIS, and minutes.
06 Lingbin is red, Mu M section 107 is blue, PM section 108 is purple,
Hour display section 109 is yellow, colon flashing second display section 110#'i
It is assumed that the minute display section 111Fi is green and has a white backlight. Then, each function is color-coded and displayed, so when the 106 MULARs or ARMs are displayed, they can be immediately recognized. In addition, it is possible to make a decorative display using only one color. 106 more, -11
For each color in 1, the border of the area changes color continuously in an analogous manner, giving a natural appearance.

I feel like cum. In the conventional polarizing plate type shown in Fig. 1, the joining part of the polarizing plate IQ, 11.12 is noticeable.
It could not be called a sim display device. 10 polarizing plates of each color
, 11.1 Cutting and pasting goose into arbitrary shapesF
! This resulted in an increase in man-hours, a decrease in yield, and an increase in costs. Sara [Polarizing plate 10. II, 12 colors are also limited to 9 loaves.

In the conventional method shown in FIG. 2, in which the liquid crystals 18, 19, 20 are divided into respective chambers by spacers 16 to display multiple colors, the spacers 16 stand out, making the display unnatural and aesthetically unsightly. In Figure 9, Mbm KM, AM.

PM, 2. :, 31. If a spacer is inserted into each boundary, the 1 display will be very hard to see^9 and the aesthetic appearance will be impaired. It was. It is very difficult to install injection ports for each of the liquid crystals 18, 19, and 20, which increases cost and reduces yield.

In addition, it is difficult to manufacture because it requires preparing 1 g and 19.20 g of liquid crystal for each color. In this method, the conventional method shown in Figs. 1 and 2 not only impairs the aesthetic appearance but also has difficulty in manufacturing and has a poor yield in order to display functional color H as shown in Fig. 9. However, the liquid crystal display device of the present invention shown in Figs. 3 to 8 would be a boost in terms of material costs.

The material cost is low, and it is highly reliable and mass-producible, and can be easily manufactured at a high yield and at low cost. It was. Any color can be produced in any pattern, and the color changes at the boundaries of each color area 106 to 111 are analog, continuous, and natural, making it visually appealing. For example, if the color element 32 is removed from the iris 3 diagram, there is an advantage that any place can be illuminated with any coloring pattern without changing the liquid crystal panel 30. It can be applied not only to a single clock but also to a variety of fields.1 For example, it can be applied to gA meters, various low-grade meters, automobile meter 1% warning devices, various indicators, etc.

With these devices, it is often necessary to always pay attention to the display, which often increases mental fatigue, nerves, and internal physical exertion. However, as shown in FIG. 9, if colors are displayed for each function, the attention of one person will be reduced accordingly, and fatigue will also be reduced. Furthermore, human Fi, tJ! LWhen you see something ugly, use B characteristics to help you feel less tired. Liquid crystal display device #-i1 having the structure shown in Fig. 11E3 to Fig. g8 of the present invention Since it has the structure of the conventional Fig. 1 to Fig. It has an attractive and decorative appearance outside the display, and therefore reduces fatigue.

FIG. 1O shows a second applied embodiment of the present invention.

11E9! This will be explained using a clock display similar to IQ. The liquid crystal panel has a negative display, and the 1 lit part is displayed due to light leakage from the 7 parts of the putter.

10th! ! Similar to FIG. 9, it is assumed that the display blocks are divided according to function and each is illuminated by a backlight of a different color. 112 Mummu RM part has red, 11
The 35M section has a backlight, the 114P wing section has a purple backlight, the 115 hour display section has a yellow backlight, the 1160 seconds display section has a green backlight, and the 1170 minute display section has a white backlight. Then,
When all the displays are blank, the entire screen shows the background color of the negative display.

Then, when a certain display is made, the color illumination corresponding to the display pattern is removed from the negative part of the liquid crystal display, and the color is also displayed at the same time as the pattern.For example, the RM display is performed. Then, the MU DARM is displayed in a negative pattern, and the red backlight behind it leaks into the negative pattern shape of the 1 MU LARM. That is,
Since the display displays colors as well as patterns, the display effect for each function is doubled. Rich in decoration! Il! Cb
It is important to not only display information, but also to provide a small amount of information that can be read from a distance. In the case of a negative display, unnecessary parts are not displayed, so only the necessary display is provided with dual display of patterns and colors, making it possible to convey more accurate and reliable information.

In the case of negative display, TM1w is explained using Fig. 3.
In the case of a crystal display, align the polarization axes of the upper and lower polarizers 92 and 96 with the orientation of the liquid crystal 97 to make a negative display (DTM@
The same applies to crystal displays; in the case of a transmission 11GH display, it is sufficient to use only one of the upper and lower polarizers 92 and 96, and the polarization axis is aligned to match the orientation of the liquid crystal 97. In the case of (2), both the upper and lower polarizers 92.96Fi are required, and in the case of other liquid crystal display devices, negative display is also performed in accordance with each display method. For negative display, black is the best color for the background of the negative. Since black absorbs all colors, it is the most efficient display, but it does not matter if other negatives are colors.

Now, as a conventional example, various polarized lights shown in Figure IIEi [10].

11.1 Negative display is performed by pasting k. Since the polarizing plates 10 and 11.12 are themselves color polarizers, each area has a color [a!] corresponding to each polarizer. tfte1
There are some drawbacks. In addition, unless the boundaries between the polarizers 10, 11, and 12 are made perfect, the boundaries will not be displayed negatively and will appear transparent, but it is difficult to bond the polarizers together without any gaps.

Also, the liquid crystals 18, 19, 20 shown in Fig. 2 are connected to the spacer 1.
6, in order to display multicolor display in each room, method Fi, even if you try to display negative, even if the LCD 1g, 19°20 part can display negative, the spacer 16s will not display negative and the part will be missing. There was a drawback. Therefore, the conventional negative display shown in FIGS. 1 and 2 is essentially difficult to make completely negative, and is also difficult to manufacture. However,
In the case of the liquid crystal display device of the present invention shown in FIGS. 3 to 8.

For example, in the liquid crystal display device of the present invention shown in Fig. tIK3, when the liquid crystal 29 is 7 mm and the upper and lower polarizers 24 and 28 are aligned to match the orientation of the liquid crystal 29 to make the background of the display part black, 112 to 1
17, the background color of each display section cannot be changed. Therefore, 112~
There is no need to worry about colors being cut out from the color display boundaries of 117 or parts of the background being partially defective. . Therefore, it is possible to realize a liquid crystal display device in which there is no boundary between 112 and 1170 m of one display block, and the entire display surface of one display block is uniformly black, and the block 112! ~117, it is possible to provide a completely uniform negative display screen rather than a pre-colored display screen. Also, what if the base of display car j was colored blue, green, or red instead of black? 1. Or, when the black background is thin, each of the block portions 112 to 117 has a different color background, but in that case also, as shown in FIGS.
If it is configured with the liquid crystal display device shown in FIG.
The A1 display screen, where the 117 boundaries are analog-like and continuously changes, is beautiful and rich in decoration, so it is not only a watch, but also a watch.
Various public expenses 1 For example, measurement a, various meters 1 car meters, various alarm devices.

It can be applied to various indicators, etc., and it reduces the number of errors in reading the display of these display devices, reduces fatigue during reading, and has other effects similar to those described in Figure 9.

As described above, the liquid crystal display device of the present invention is highly mass-producible, can be produced with high yield, and is inexpensive. In addition, it is suitable for various applications such as illumination in any color and in any pattern, and displays for each function.
It is a great contribution to the development of industry.
