BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device,
The present invention relates to a field-effect liquid crystal display device having particularly excellent time-division driving characteristics and capable of monochrome and multicolor display.

[0002]

2. Description of the Related Art As one type of liquid crystal display device, a so-called twisted nematic type (TN) is a spiral structure twisted by 90 degrees by a nematic liquid crystal having a positive dielectric anisotropy between two electrode substrates. In addition, a polarizing plate is disposed outside both electrode substrates such that the polarization axis (or absorption axis) thereof is orthogonal or parallel to the liquid crystal molecules adjacent to the electrode substrate (Japanese Patent Publication No. -136
No. 66).

In such a liquid crystal display device having a twist angle (α) of 90 degrees, there are problems in terms of the steepness (γ) of the change in the transmittance of the liquid crystal layer versus the voltage applied to the liquid crystal layer and the viewing angle characteristic. ,
The number of time divisions (corresponding to the number of scanning electrodes) was 64, which was a practical limit. However, in order to cope with the recent demands for improving the image quality and increasing the display information amount for liquid crystal display elements, a super twisted nematic (STN) has been proposed in which the twist angle α of liquid crystal molecules is larger than 180 degrees, and the birefringence of this STN is Applied Physics is to improve the time-division drive characteristics and increase the number of time-division by utilizing the effect.
Letter 45, No.10, 1021 1984 (Applied Physics Lette
r, TJScheffer, J.Nehring: "A new, highly multiplexab
le liquidcrystal display "), and a super twisted birefringence effect (SBE) liquid crystal display device has been proposed.

This type of liquid crystal display device includes a liquid crystal display panel including an upper frame having a display window, a liquid crystal plate in which a drive circuit board is integrated, a light guide assembly including a light diffusion plate and a light guide plate, This light guide assembly is housed and at least one side has an intermediate frame on which a linear Bakulite light source is mounted and a lower frame, and these are laminated in the above order,
The upper frame and the lower frame are connected and fixed.

[0005]

In the above-mentioned conventional liquid crystal display device, one surface of a sponge spacer with a double-sided tape is attached to the inside of the upper frame as a spacer to be inserted between the upper frame and the liquid crystal display panel. Then, by sticking the other surface to the terminal part of the liquid crystal display panel,
The upper frame, which is a metal plate, and the liquid crystal display panel are joined and fixed to each other to perform impact-resistant superposition.

However, the above-mentioned sponge spacer with double-sided tape has a poor linear holding property, and it is difficult to attach the sponge spacer along the upper frame so as to be accurately positioned on the terminal portion of the liquid crystal display panel, and it takes time to perform the work. When it is meandered and pasted, a gap remains between the upper frame and the liquid crystal display panel, or the upper frame directly faces the liquid crystal display panel, and the liquid crystal display panel is damaged by the application of impact. There was a problem.

The object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a liquid crystal display in which the upper frame and the liquid crystal display panel are joined with impact resistance using spacers having good workability and not meandering. To provide a device.

[0008]

A liquid crystal display device in which a frame-shaped intermediate frame 42 for mounting a light source 36 and a lower frame 2 are laminated in this order, and the upper frame 1 and the lower frame 2 are connected and fixed to each other. It has a jetty 67-A, 67-B which projects along the long side toward the liquid crystal display panel side, and is made of a resin thin plate having adhesive layers formed on both sides between the jetty and the terminal portion of the liquid crystal display panel. The stripe-shaped spacers 14-A and 14-B are inserted.

[0009]

The jetty 67-A, 67-B formed along at least the long side of the upper frame 1 prevents the portion of the upper frame 1 facing the liquid crystal display panel 62 from directly contacting the liquid crystal display panel. The striped spacers 14-A and 14-B made of a resin thin plate interposed between the jetty 67-A and 67-B and the terminal portion of the liquid crystal display panel 62 maintain the linearity by themselves. Along with the jetty of the frame 1 and the terminal portion of the liquid crystal display panel, the both are fixed by the adhesive material.

Hereinafter, a specific example in which the above configuration is applied to a liquid crystal display device of a super twisted nematic (STN) system will be described. In the following drawings, components having the same function are designated by the same reference numeral, and repeated description thereof will be omitted. "Specific Example 1" FIG. 4 shows the alignment direction (for example, rubbing direction) of liquid crystal molecules, the polarization direction (or absorption axis) direction of a polarizing plate, when the liquid crystal display device 62 according to the present invention is viewed from above. FIG. 5 shows the optical axis direction of the member that produces the birefringence effect, and FIG.
The principal part 2 perspective view is shown.

Twisting direction 10 of liquid crystal molecules and twist angle θ
Is the rubbing direction 6 of the alignment film 21 on the upper electrode substrate 11, the rubbing direction 7 of the alignment film 22 on the lower electrode substrate 12, and the nematic liquid crystal layer 50 sandwiched between the upper electrode substrate 11 and the lower electrode substrate 12. It is defined by the type and amount of the optically active substance added. In FIG. 5, in order to align the liquid crystal molecules between the two upper and lower electrode substrates 11 and 12 sandwiching the liquid crystal layer 50 so as to form a twisted spiral structure, the upper and lower electrode substrates 11 and 12 are A so-called rubbing method, which is a method of rubbing the surfaces of the alignment films 21 and 22 made of an organic polymer resin made of polyimide in contact with the liquid crystal with a cloth, for example, in one direction, is adopted. The rubbing direction at this time, that is, the rubbing direction, the rubbing direction on the upper electrode substrate 11 and the rubbing direction 7 on the lower electrode substrate 12 are the alignment directions of the liquid crystal molecules.

On the two sheets thus oriented,
The lower electrode substrates 11 and 12 are respectively rubbed in directions 6 and 7
Are opposed to each other with a gap d ₁ so that they cross each other at about 180 to 360 degrees.
Is bonded by a frame-shaped sealing material 52 having a notch 51 for injecting liquid crystal, and a nematic liquid crystal having a positive dielectric anisotropy and a predetermined amount of an optical rotatory substance added is sealed in the gap, whereby liquid crystal molecules are Is the twist angle θ between the electrode substrates in the figure.
The molecular arrangement has a helical structure. In addition, 31 and 32 are upper and lower electrodes, respectively.

A member (hereinafter, referred to as a birefringent member) 40 for providing a birefringence effect is disposed above the upper electrode substrate 11 of the liquid crystal cell 60 thus constructed, and further, the member 40 and the liquid crystal. Upper and lower polarizing plates 15 and 16 are provided with the cell 60 interposed therebetween. The twist angle θ of the liquid crystal molecules in the liquid crystal 50 is preferably 200 degrees to 300 degrees, but excellent time division characteristics are avoided by avoiding the phenomenon that the lighting state near the threshold value of the transmittance-applied voltage curve is an orientation that scatters light. From the practical viewpoint of maintaining the above condition, the range of 230 degrees to 270 degrees is more preferable.

This condition basically acts to make the response of the liquid crystal molecules to the voltage more sensitive and to realize an excellent time division characteristic. In order to obtain excellent display quality, the product [Delta] n ₁ · d ₁ of the refractive index anisotropy [Delta] n ₁ and a thickness d ₁ of the liquid crystal layer 50 is preferably from the 0.5 [mu] m 1.0 micron
m, more preferably 0.6 μm to 0.9 μm.

The birefringent member 40 acts so as to modulate the polarization state of the light passing through the liquid crystal cell 60, and converts the display which is only colored by the liquid crystal cell 60 into a black and white display. For this purpose, the product [Delta] n ₂ · d ₂ of the refractive index anisotropy [Delta] n ₂ and the thickness d ₂ of the birefringent member 40 is extremely important, 0.8 micron preferably from 0.4μm
m, more preferably 0.5 μm to 0.7 μm.

Further, since the liquid crystal display device 62 according to the present invention uses the elliptically polarized light due to the birefringence, the polarizing plate 15,
When the uniaxial transparent birefringent plate is used as the birefringent member 40, the relationship between the 16 axes and the liquid crystal alignment directions 6 and 7 of the electrode substrates 11 and 12 of the liquid crystal cell 60 is extremely important. . Here, the action and effect of the above relationship will be described with reference to FIG. This figure shows the relationship between the axis of the polarizing plate, the optical axis of the uniaxial transparent birefringent member, and the liquid crystal alignment direction of the electrode substrate of the liquid crystal cell when the liquid crystal display device having the configuration of FIG. 5 is viewed from above. is there.

In FIG. 4, 5 is the optical axis of the uniaxial transparent birefringent member 40, 6 is the liquid crystal alignment direction of the birefringent member 40 and the upper electrode substrate 11 adjacent thereto, and 7 is the liquid crystal alignment of the lower electrode substrate 12. Direction 8 is the absorption axis or polarization axis of the upper polarizing plate 15, the angle α is the angle between the liquid crystal alignment direction 6 of the upper electrode substrate 11 and the optical axis 5 of the uniaxial birefringent member 40, and the angle β is the upper direction. The angle γ between the absorption axis or polarization axis 8 of the polarizing plate 15 and the optical axis 5 of the uniaxial transparent birefringent member 40 is the absorption axis or polarization axis 9 of the lower polarizing plate 16 and the lower electrode substrate 1.
2 is the angle formed by the liquid crystal alignment direction 7.

Here, a method of measuring the angles α, β and γ will be defined. In FIG. 9, the intersection angle between the optical axis 5 of the birefringent member 40 and the liquid crystal alignment direction 6 of the upper electrode substrate 11 will be described as an example. The intersection angle between the optical axis 5 and the liquid crystal alignment direction 6 can be represented by φ ₁ and φ ₂ as shown in FIG. 8, but the smaller angle of φ ₁ and φ ₂ is adopted here. That is, since φ ₁ <φ ₂ in FIG.
₁ is the intersection angle between the optical axis 5 and the liquid crystal alignment direction 6, and since φ ₁ > φ ₂ in FIG. 9B, φ ₂ is the intersection angle between the optical axis 5 and the liquid crystal alignment direction 6. Of course, either _one may be adopted when φ ₁ = φ ₂ .

In this type of liquid crystal display device, the angles α, β and γ are extremely important. The angle α is preferably 5
0 to 90 degrees, more preferably 70 to 90 degrees,
The angle β is preferably 20 to 70 degrees, more preferably 30 to 60 degrees, and the angle γ is preferably 0 to 70 degrees.
It is desirable to set the angle to 0 degree, more preferably to 0 degree to 50 degree.

If the twist angle θ of the liquid crystal layer 50 of the liquid crystal cell 60 is in the range of 180 ° to 360 °, the above angle α is set regardless of whether the twist direction 10 is clockwise or counterclockwise. , Β, γ may be within the above range. In FIG. 5, the birefringent member 40 is provided between the upper polarizing plate 15 and the upper electrode substrate 11, but instead of this, it is provided between the lower electrode substrate 12 and the lower polarizing plate 16. Good. In this case, the entire configuration of FIG. 5 is inverted. "Specific example 2" The basic structure is the same as that shown in FIGS. In FIG. 6, the twist angle θ of the liquid crystal molecule is 2
A liquid crystal cell having a parallel orientation (homogeneous orientation), that is, a twist angle of 0 degree was used as the uniaxial transparent birefringent member 40.

Here, the ratio d / p of the thickness d (μm) of the liquid crystal layer and the helical pitch p (μm) of the liquid crystal material added with the optical rotatory substance was set to about 0.53. The alignment films 21 and 22 were formed of a polyimide resin film and used after being rubbed. The tilt angle (pretilt angle) at which the alignment film subjected to the rubbing process causes the liquid crystal molecules in contact with the alignment film to be tilted with respect to the substrate surface is about 4 degrees. Δn ₂ · d ₂ of the uniaxial transparent birefringent member 40 is about 0.6 μm.
On the other hand, Δn ₁ · d ₁ of the liquid crystal layer 50 in which the liquid crystal molecules are twisted by 240 degrees is about 0.8 μm.

At this time, by setting the angle α to about 90 degrees, the angle β to about 30 degrees, and the angle γ to about 30 degrees, the voltage applied to the liquid crystal layer 50 via the upper and lower electrodes 31 and 32 is increased. It was possible to realize light non-transmission, that is, black display when the voltage was below the threshold, and light transmission, that is, white and black display when the voltage was above a certain threshold. Further, when the axis of the lower polarizing plate 16 is rotated from the above position by 50 to 90 degrees, when the voltage applied to the liquid crystal layer 50 is below the threshold value, it is white, and when the voltage is above the threshold value, it is black. Black and white display was realized.

FIG. 7 shows a change in contrast during time-division driving at 1/200 duty when the angle α is changed in the configuration of FIG. Although the contrast was extremely high when the angle α was in the vicinity of 90 degrees, the contrast decreased as the angle deviated. Moreover, when the angle α becomes small, both the lit part and the non-lit part become bluish, and when the angle α becomes large, the non-lit part becomes purple and the lit part becomes yellow, and in any case black and white display is impossible. Similar results are obtained for the angle β and the angle γ, but in the case of the angle γ, when the image is rotated from 50 degrees to 90 degrees, the opposite black and white display is performed. The basic structure of "Specific Example 3" is the same as that of "Specific Example 2". However, the twist angle of the liquid crystal molecules of the liquid crystal layer 50 is 260
The difference is that Δn ₁ · d ₁ is about 0.65 μm to 0.75 μm. Δn ₂ · d ₂ of the parallel alignment liquid crystal layer used as the uniaxial transparent birefringent member 40 is about 0.58 μm, which is the same as in “Specific Example 2”.

At this time, by setting the angle α to about 100 degrees, the angle β to about 35 degrees, and the angle γ to about 15 degrees, the black and white display similar to the "concrete example 1" can be realized. Also, the reverse black-and-white display is possible by rotating the position of the axis of the lower polarizing plate from the above value by 50 to 90 degrees, which is also the same as "Specific example 2". The inclinations of the angles α, β, and γ with respect to the shift are almost the same as in “Specific Example 2”.

In each of the above embodiments, a parallel alignment liquid crystal cell having no twist of liquid crystal molecules is used as the uniaxial transparent birefringent member 40, but a liquid crystal layer in which liquid crystal molecules are twisted by about 20 to 60 degrees is used. When used, the color changes less depending on the angle. This twisted liquid crystal layer is the liquid crystal layer 5 described above.
Like 0, it is formed by sandwiching a liquid crystal between a pair of transparent substrates that have been subjected to the alignment treatment so that the alignment treatment directions intersect a predetermined twist angle. In this case, the bisected angle of the two alignment treatment directions sandwiching the twisted structure of the liquid crystal molecules may be treated as the optical axis of the birefringent member.

A transparent polymer film may be used as the birefringent member 40 (in this case, a uniaxially stretched film is preferable). In this case, as the polymer film, PET
(Polyethylene terephthalate), acrylic resin, and polycarbonate are effective. Further, in the above specific example, the single birefringent member was single, but in FIG.
In addition to the birefringent member 40, the lower electrode substrate 12 and the lower polarizing plate 1
It is also possible to insert another birefringent member between 6 and 6. In this case, Δn ₂ · d ₂ of these birefringent members may be readjusted. "Specific example 4" The basic structure is the same as that of "specific example 2." However, as shown in FIG. 10, red,
Multicolor display is possible by providing the green and blue color filters 33R, 22G, 33B and the light shielding film 33D between the filters. FIG. 8 shows the relationship among the alignment direction of the liquid crystal molecules, the twisting direction of the liquid crystal molecules, the direction of the axis of the polarizing plate, and the optical axis of the birefringent member in “Specific Example 4”.

In FIG. 10, a smoothing layer 23 made of an insulating material is formed on each of the color filters 33R, 22G, 33B and the light shielding film 33D to reduce the influence of these irregularities. The upper electrode 31 and the alignment film 21 are formed. FIG. 11 shows a block diagram in which the liquid crystal display module 63 according to the present invention shown in FIG. 1 is used for a display portion of a laptop personal computer, and FIG.

In FIG. 11, the microprocessor 49
The liquid crystal display module is driven by the drive IC 34 via the control LSI 48 based on the result calculated in (4). According to the present embodiment configured as described above, the work of attaching the stripe-shaped spacers becomes extremely easy, and the spacers are accurately arranged along the sides of the upper frame without the meandering attachment unlike the conventional sponge spacers. Therefore, the upper frame and the liquid crystal non-panel can be fixed with impact resistance.

The invention described in the claims of the present invention is not limited to the above-mentioned STN type liquid crystal display device, but can be similarly applied to other type liquid crystal display devices equipped with a backlight. Is.

As described above, according to the present invention,
By inserting a striped spacer made of a thin resin plate between the jetty provided on the upper frame and the terminal part of the liquid crystal non-panel, the part of the upper frame facing the liquid crystal display panel should be in direct contact with the liquid crystal display panel. Since the above-mentioned stripe-shaped spacer itself maintains linearity, it is possible to provide a liquid crystal display device that improves workability and sufficiently withstands an external impact.
