No. 07216, U.S. Pat. No. 4,367,924, U.S. Pat. No. 4,563,059, etc., surface-stabilized FLC (Surface-stabilized fC)
erroelectric liquid crystal
A bistable FLC device according to l) was revealed. This bistable FLC element is composed of a pair of sufficiently small intervals for controlling the formation of a helical alignment structure of liquid crystal molecules in a bulk chiral smectic C phase (SmC ^* phase), H phase (SmH ^* ), etc. It was realized by arranging liquid crystals between the substrates and arranging vertical molecular layers organized by a plurality of liquid crystal molecules in one direction.

Regarding a display element using such an FLC, as disclosed in Japanese Patent Laid-Open No. 94023/1986, a cell gap of about 1 to 3 μm is maintained on the inner surfaces of two sheets. It is known that FLC is injected into a liquid crystal cell formed by facing glass substrates on which transparent electrodes are formed and subjected to orientation treatment.

The characteristics of the FLC device are that the FLC has spontaneous polarization, so that the coupling force between the external electric field and the spontaneous polarization can be used for switching, and the long axis direction of the FLC molecule is the polarization direction of the spontaneous polarization. Since it corresponds to the pair 1, it is possible to switch depending on the polarity of the external electric field. That is, in the state of the chiral smectic phase, one of the first optical stable state and the second optical stable state is taken in response to the applied electric field, and when the electric field is not applied, the state is changed. It is expected to be widely used in the field of display devices that have a property of maintaining, that is, bistability, and have a fast response at a change in an electric field, a high speed, and a memory type.

As described above, since FLC generally uses chiral smectic liquid crystals (SmC ^* , SmH ^* ), the liquid crystal molecule has a twisted orientation in the bulk state, but the above-mentioned cell gap of about 1 to 3 μm. The twist of the long axis of the liquid crystal molecule can be eliminated by putting it in a cell (p.213 to 234, NA Clark et.
al, MCLC, 1983, vol. 94).

A liquid crystal display device provided with a display panel formed of such FLC elements is disclosed in, for example, US Pat. No. 465 of Kamibe et al.
An image can be formed on the display screen of large-capacity pixels by using the multiplexing driving method described in the specification of No. 5561. The above liquid crystal display device,
It can be used for display screens of word processors, personal computers, micro printers, televisions and the like.

The FLC element is mainly used as a binary (white / black) display element in which two stable states are set to a light transmitting state and a light blocking state, but multi-value display, that is, halftone display is also possible. One of the halftone display methods is to create an intermediate light transmission state by controlling the area ratio of bistable states in a pixel. Hereinafter, this method (area modulation method) will be described in detail.

FIG. 5 is a diagram schematically showing the relationship between the switching pulse amplitude and the transmittance of the FLC element. A single-polarity single-shot pulse is applied to a cell (element) that was initially in a completely light-blocking (black) state. 7 is a graph in which the amount I of transmitted light after being plotted is plotted as a function of the amplitude V of a single pulse. When the pulse amplitude is less than or equal to the threshold value V _th (V <V _th ), the amount of transmitted light does not change, and the transmission state after the pulse application is the state before the application as shown in FIG. 6 (b). Does not change. When the pulse amplitude exceeds the threshold value (V _th <V <V _sat ), a part of the pixel transits to the other stable state, that is, the light transmission state shown in FIG. 7C, and shows an intermediate amount of transmitted light as a whole. Further, the pulse amplitude becomes larger, and the saturation value is V _sat or more (V _sat <V).
Then, as shown in FIG. 7D, all the pixels are in the light transmitting state, so that the light amount reaches a constant value. That is, in the area modulation method, the voltage is controlled so that the pulse amplitude becomes V _th <V <V _sat ) and the halftone is displayed.

However, in such a simple driving method,
Since the relationship between the voltage and the amount of transmitted light in FIG. 5 also depends on the cell thickness and the temperature, if there is a cell thickness distribution or a temperature distribution in the display panel, different gradation levels are displayed for the applied pulse of the same voltage amplitude. There is a problem that it will be done.

FIG. 7 is a diagram for explaining this, and is a graph showing the relationship between the voltage amplitude V and the transmitted light amount I as in FIG. 5, but the relationship at different temperatures, that is, high temperature and low temperature, is shown by curves. Shown by H and curve L. That is, in a display (display element) having a large display size, it is not uncommon for a temperature distribution to occur in the same panel (display portion), and therefore, even if an attempt is made to display a halftone with a certain voltage V _ap , it is shown in FIG. As described above, the halftone level varies over the range from I ₁ to I ₂ , and a uniform display cannot be obtained.

What has been devised there is the "4-pulse method" proposed by the present inventor in Japanese Patent Laid-Open No. 218022/1992. This driving method applies a plurality of pulses (A, B, C, D in FIG. 9) for a low threshold portion and a high threshold portion on the same scanning line in the panel as shown in FIGS. 8 and 9. As a result, the same inverted area is finally obtained ((D) in FIG. 8).

The inventor of the present invention is further in Japanese Patent Application No. 3-320542.
In this issue, the "pixel shift method" is proposed in which the writing time is shorter than the "4 pulse method".

The pixel shift method is a method in which different scanning signals are input to a plurality of scanning signal lines at the same time and selected, thereby creating a distribution of electric field intensity across a plurality of scanning signal lines and displaying in gradation.

The outline of the pixel shift method will be described below.

A liquid crystal cell that can be used has a distribution of threshold values within one pixel, as shown in FIG. In the cell shown in FIG. 10, the FLC layer 55 between the electrodes is
Since the layer thickness of is changed, the switching threshold of FLC also has a distribution. When the voltage applied to such a pixel is increased, switching is performed in order from the portion having the smallest cell thickness.

This state is shown in FIG. 11 (a). Figure 11
In (a), T ₁ , T ₂ , and T ₃ indicate the temperatures of the observed portion in the panel. The switching threshold voltage of the FLC decreases as the temperature increases, and the relationship between the applied voltage and the light transmittance at the above three temperatures is shown by three curves.

Although there are other causes of the threshold value fluctuation than the temperature change, for convenience of explanation, the mode will be described mainly by using the temperature change.

As can be seen from FIG. 11A, when the voltage of V _i is applied to the pixel at the temperature T ₁ after _first resetting the entire pixel to the dark state, the transmittance of X% can be obtained. Increases to T ₂ or T ₃ , the same V _i
Even if the voltage of 2 is applied to the pixel, the transmittance becomes 100%, and the gradation display cannot be performed correctly. Figure 11
(C) shows the inverted state of the pixel after writing at each of the above temperatures. Under such a condition, the written gradation information is lost due to the temperature change, so that the application range as a display element is extremely limited.

Therefore, as shown in FIG.
By displaying the pixel information across the _two scanning signal lines S ₁ and S ₂ , it is possible to perform stable gradation display against temperature fluctuations.

The drive system will be described in detail below.

FLC having a continuous threshold distribution within a pixel
Prepare Cell: The liquid crystal cell may have a structure in which the cell thickness in the pixel is continuously distributed as shown in FIG. In addition, the applicant of the present invention has disclosed that
A configuration having a potential gradient in a pixel or a configuration having a capacitance gradient may be used as proposed in Japanese Patent Laid-Open No. In any case, by continuously distributing the threshold values in the pixel, the region (domain) corresponding to the bright state and the region (domain) corresponding to the dark state can be mixed in the pixel. The gradation ratio can be displayed by the area ratio.

This method can be used even when the light quantity is modulated stepwise (for example, 16 gradations), but continuous light quantity change is necessary for analog gradation display.

Selecting two scanning signal lines simultaneously: This operation will be described with reference to FIG. Figure 12 (a)
Shows the transmittance-applied voltage characteristics when the pixels on the two scanning signal lines are grouped together. In FIG. 12A, the transmittance 0% to 100% is shown as the display area of the pixel B on the scanning signal line 2, and the transmittance 100% to 200% is shown as the display area of the pixel A on the scanning signal line 1. ing. That is, since one scanning signal line constitutes one pixel, when two scanning lines are simultaneously scanned, the transmittance is 200% when both the pixel A and the pixel B are in the light transmitting state. here,
Two scanning signal lines are simultaneously selected for one gradation information, but an area having an area of one pixel is allocated to display one gradation information. This will be described with reference to FIG.

At the temperature T ₁ , the inputted gradation information is written in a range corresponding to 0% when the applied voltage V ₀ and ₁₀₀ % when the applied voltage V 100. As is apparent from the figure, at the temperature T ₁ , this range (pixel area) is entirely on the scanning signal line 2 (see the shaded portion in FIG. 12B). However, the temperature is T
_{When the} voltage is increased from ₁ to T ₂ , the threshold voltage of the liquid crystal is lowered, so that when the same voltage is applied to the pixel, a wider region in the pixel is inverted than when the temperature is T ₁ .

In order to correct this, the pixel area at the temperature T ₂ is set over the scanning signal line 1 and the scanning signal line 2 (the shaded portion showing the case of the temperature T _{2 in} FIG. 12B). ).

Next, when the temperature further rises to T ₃ , the applied voltage is changed from V _{0 to} V ₁₀₀ to set the pixel area to be drawn only on the scanning signal line 1 (FIG. 12).
The shaded portion showing the case of the temperature T _{3 in} (b)).

As described above, by setting the pixel regions for gradation display depending on the temperature so as to be shifted on the two scanning signal lines, it is possible to maintain correct gradation display in the temperature range from T ₁ to T _3. become.

It is assumed that the scanning signals applied to the two scanning signal lines selected at the same time are different from each other: As described above, the threshold variation of liquid crystal inversion due to the temperature change is 2
In order to compensate by simultaneously selecting two scanning signal lines, the scanning signals applied to the two selected scanning signal lines must be different from each other. This point will be described with reference to FIG.

The scanning signals applied to the scanning signal lines 1 and 2 are set so that the thresholds of the pixels B on the scanning signal line 2 and the pixels A on the scanning signal line 1 continuously change. In FIG. 11B, the transmittance-voltage curve when the temperature is T ₁ shows that the transmittance is displayed up to 100% in the area on the scanning signal line 2, and then 200% is scanned signal line. 1 is displayed in the upper area. As described above, it is necessary to set the transmittance-voltage curve from the pixel B to the pixel A continuously and with an equal gradient.

Therefore, as shown in FIG. 13, the cell shapes of the pixel A on the scanning signal line 1 and the pixel B on the scanning signal line 2 (see FIG. 13).
Even if (b) is set to be equal, the same display as in the case where substantially continuous threshold characteristics are given to the pixel A and the pixel B (cell in FIG. 11B) is possible.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
When gradation display is performed using, the propagation delay of the electric signal in the liquid crystal panel becomes a problem. LCD panel (input I
The propagation delay of the voltage waveform of the resistance component inside C (including 1 kΩ / line) is determined by the capacitance of the liquid crystal layer, the amount of current associated with the reversal of spontaneous polarization, the wiring resistance of the electrodes, the internal resistance of the IC, and the like. .

If the spontaneous polarization of the FLC is about 6 nc / cm ² , the influence on the rise of the pulse can be neglected. Therefore, the rounding of the voltage waveform (delay of the rise of the applied voltage pulse) is equal to the capacitance of the liquid crystal. In a display having a display area of 280 mm x 220 mm, which is determined by the wiring resistance, one signal line has a capacitance of about 1314 pF, the wiring resistance is about 4.1 kΩ, and the internal resistance of the IC is about 1 kΩ, so the wiring resistance is About 5.1kΩ
It becomes (common side), and the rounding of the waveform is about 15.4 μs at the rise from 0% to 90%. In the same cell, the segment side (information signal input side) has a wiring resistance of 6.4 kΩ, I
The C internal resistance is 1.0 kΩ, and the rounding is about 22.0 μs at the rise from 0% to 90%.

The dullness inside the panel is distributed from about 2.7 μs to about 22.0 μs. As shown in FIG. 10, when the gradation display is performed by changing the electric field strength by the method of changing the liquid crystal layer thickness (cell thickness), there is the following relationship with the rounding.

[0034]

[Table 1]

Therefore, since a difference (variation) of 18% or more occurs in the inside of the panel, the display quality is remarkably deteriorated.

[0036]

The present invention has been achieved in view of the above-mentioned problems, and by providing a thick film metal wiring embedded in an organic resin layer on an electrode substrate constituting a liquid crystal cell, The wiring resistance in the liquid crystal panel is lowered to reduce the rounding of the input waveform to the pixel. That is, the present invention is a method of manufacturing a liquid crystal element in which a ferroelectric liquid crystal is sandwiched between a pair of electrode substrates arranged to face each other, and the intersections of the scanning electrode groups and the information electrode groups provided on the respective electrode substrates are pixels. Therefore, the UV curable resin is placed on the substrate on which the metal wiring is formed, and the mold having a predetermined shape is pressed to fill the UV curable resin between the metal wirings, and the UV curable resin is exposed to expose the UV curable resin. After being cured, a transparent electrode is formed on the transparent electrode, which is a method of manufacturing a liquid crystal element.

By thus reducing the rounding of the voltage waveform, it is possible to reduce the unevenness of halftone display in the liquid crystal cell.

【Example】

Example 1 As a first example of the present invention, a liquid crystal substrate as shown in FIG. 1 (c) was produced. In FIG. 1, 11 is a die whose KN surface is ground, 12 is a thick film (2 μm) wiring metal, 13 is a UV curable resin, 14 is a glass substrate, and 15 is I.
The TO electrode 16 is an alignment film.

FIG. 1C shows an electrode substrate for providing a distribution of upper and lower electrode intervals in the pixel, where the surface of the ITO film 15 has an angle with respect to the surface of the glass substrate 14.

1 (a) and 1 (b) show the manufacturing process of this embodiment, in which the KN surface is ground with a diamond cutting tool as the mold 11, and the dimensions are A = 200 μm and B = 40.
μm, C = 0.5 μm, D = 20 μm, E = 2.0 μm
And

As the manufacturing procedure, the metal wiring 12 is formed on the glass substrate 14, the UV curable resin is dropped, and then the mold 1 is used.
1 is brought into contact with the metal wiring 12 and pressure is applied.
It is desirable that the resin layer on the metal wiring 12 be removed or be sufficiently thin (about 2000 Å or less). The strength of the pressure required for that depends on the viscosity of the UV curable resin, but it is approximately 19k
By applying a pressure of about gf / cm ² , the resin on the metal wiring 12 could be made sufficiently thin.

In this manner, the mold 11 and the glass substrate 14 are adhered to each other with the UV curable resin 13 sandwiched therebetween, using the metal wiring as a spacer, and ultraviolet rays are emitted from the direction of the surface of the glass substrate 14 on which the metal wiring 12 is not formed. The UV curable resin is cured by irradiation (UV intensity is about 500 mJ / cm
² ). After that, the mold 11 was peeled off from the glass substrate 14 to form an electrode substrate in which metal wiring was embedded in UV curable resin. In this step, silane coupling treatment was performed on the glass substrate side to improve the adhesiveness with the UV resin.

An acrylic resin manufactured by Nippon Kayaku Co., Ltd. was used as the UV curable resin, and A-174 manufactured by Nippon Yunika Co., Ltd. was diluted to 5% with methanol and used as the silane coupling material.

An ITO film is sputtered and patterned on the metal wiring embedded substrate thus manufactured,
Furthermore, an alignment film L manufactured by Hitachi Chemical Co., Ltd.
Q-1802 was formed to a thickness of about 300Å to form the electrode substrate shown in Fig. 1 (c).

The electrode substrate on the opposite side is formed by forming the same alignment film on the stripe electrode, and does not have an uneven shape.

The rubbing directions of the upper and lower substrates were parallel to each other, and the rubbing direction of the lower substrate was shifted by about 6 ° from the rubbing direction of the upper substrate to form a cell.
Cell thickness control is about 1.10 μm in the thin part,
The thick portion was set to 1.64 μm. In addition, the stripe electrode of the lower substrate was patterned in a stripe shape along the ridges so that one side of the saw shape was one pixel.

The width of the stripe electrode was set to 300 μm, and the pixel size was set to a rectangle of 300 μm × 200 μm.

As the material of the metal wiring in this embodiment, Al has a ρ of about 3.5 × 10 ^-6 Ωcm, and Mo has a ρ of about 1.2 × 10 ^-5 Ωcm. When the metal wiring was made of Al, the rounding amount (0 to 90% voltage rising amount) was improved to about 2 μm.

The liquid crystal materials used are shown in Table 1.

[Table 2]

On the other hand, FIG. 2 is a block diagram of the display device according to this embodiment, and FIG. 3 is a communication timing chart of image information.

The operation will be described below with reference to the drawings. The graphics controller 102 displays the scanning line address information designating the scanning electrodes and the image information (PD0 to PD3) on the scanning lines designated by the address information on the display drive circuit (the scanning line drive circuit 104 and the information line) of the liquid crystal display device 101. It is configured by the driving circuit 105) and transferred to 104/105. In the present embodiment, the image information having the scanning line address information and the display information is transferred through the same transmission line, so that the two types of information must be distinguished. The signal for this identification is AH / DL, and this AH / DL signal is H
At the time of level, it indicates that it is scanning line address information,
At the L level, it indicates that the information is display information.

The scanning line address information is used for the liquid crystal display device 10.
The image information PD0 to PD on the side of the drive control circuit 111 in 1
After being extracted from the image information transferred as 3,
It is output to the scanning line driving circuit 104 at the timing of driving the designated scanning line. This scanning line address information is input to the decoder 106 in the scanning line driving circuit 104, and the designated scanning electrode of the display panel 103 is driven by the scanning signal generating circuit 107 via the decoder 106. On the other hand, the display information is guided to the shift register 108 in the information line driving circuit 105 and is shifted in units of 4 pixels by the transfer clock. When the shift register 108 completes the shift of one scanning line in the horizontal direction, the display information for 1280 pixels is transferred to the line memory 109 provided side by side and stored for one horizontal scanning period, and the information signal generating circuit 110 is displayed. Is output as a display information signal to each information electrode.

Further, in this embodiment, since the driving of the display panel 103 in the liquid crystal display device 101 and the generation of the scanning line address information and the display information in the graphics controller 102 are performed asynchronously, the image information is transferred between the devices. It is necessary to synchronize (101/102). The signal that controls this synchronization is SYNC, which is generated in the drive control circuit 111 in the liquid crystal display device 101 every horizontal scanning period. The graphics controller 102 always monitors the SYNC signal, and transfers the image information if the SYNC signal is at the L level, and conversely when the SYNC signal is at the H level, transfers after the transfer of the image information for one horizontal scanning line. Do not do. That is, in FIG. 2, when the graphics controller 102 detects that the SYNC signal has become L level, it immediately sets the AH / DL signal to H level and starts the transfer of image information for one horizontal scanning line. The drive control circuit 111 in the liquid crystal display device 101 sets the SYNC signal to the H level during the image information transfer period. After the writing to the display panel 103 is completed after a predetermined one horizontal scanning period, the drive control circuit (FLCD controller) 111 displays SY.
The NC signal can be returned to the L level again to receive the image information of the next scanning line.

(Embodiment 2) FIG. 4 shows a second embodiment of the present invention.

When the liquid crystal cell becomes large, the adhesion area between the UV curable resin and the mold increases, and it becomes very difficult to separate the mold after curing the resin, which causes a reduction in process yield.

The present embodiment is an example in which this problem is solved by providing a release layer (41 in FIG. 4) on the surface of the mold. As the resin used for this release layer, it is preferable that the adhesive force with the UV curable resin is weak and the strength of the resin itself is low. For example, a water-soluble PVA (polyvinyl alcohol) resin or a positive resist is suitable.

In this embodiment, the PVA resin layer was provided as described below, but it is considered that the mold surface may be vapor-treated with a liquid that is incompatible with the Langmuir film or the UV curable resin. Alternatively, the first layer may be formed of an alkylfluoride-based thin film, and a resin layer for peeling may be formed thereon.

The PVA resin in this example is 3 at 80 °.
What was baked for 0 minutes was used.

In the present embodiment, the metal wiring reduced the rounding of the voltage waveform and at the same time improved the yield in the manufacturing process.

(Embodiment 3) FIG. 14 shows a third embodiment of the present invention.
Shown in. First, about 1 μm of metal wiring is formed on the glass substrate 14 (a). Next, a color filter layer (R, G, B) is formed on the substrate (b). A metal wiring having the same pattern as the metal wiring formed in (a) is formed on the already formed metal wiring 12 (about 5000 Å) (c). UV curable resin was dropped on the substrate (d), and a light-shielding metal layer at the time of exposure was provided on the surface in the same shape as the metal wiring. From above, a transparent substrate having a smooth surface is pressed as the mold 11 (e). After the glass substrate 14 and the mold 11 are pressed against each other with sufficient force, UV light is irradiated from the mold 11 side for exposure (the condition is 700 mJ / cm ² for 1 min). After the UV resin is cured, the mold 11 that has been pressed is separated from the glass substrate 14 (f).

The amount of resin remaining on the metal wiring 12 is determined by the smoothness of the mold and the pressure during pressure bonding, but 10 kgf
When a force of / cm ² was applied, a resin layer of about 3000 Å remained partially. However, since the resin layer remaining on the metal wiring in this way is not cured, it can be removed by washing. Therefore, after cleaning, an ITO film can be formed and patterned to make electrical contact with the metal wiring.

Depending on the thickness of the residual resin layer on the metal wiring, the ITO layer and the metal wiring may be electrically insulated, but in this case, the ITO-metal disconnection portion contains Cr.
Can be made conductive by vapor deposition and patterning with a thickness of about 1000Å (h).

In this embodiment, the width of the metal wiring is about 20 μm.
set to m. The same UV curable resin as in Example 1 was used, and the glass substrate side was subjected to silane coupling treatment.
