Abstract

A liquid crystal is arranged between a pair of substrates. One substrate has a plurality of stripe electrodes extending parallel to each other, and the other substrate has a transparent electrode covering substantially the whole surface of the other substrate. An oblique electric field is formed between the stripe electrodes and the transparent electrode, so that the liquid crystal molecules are aligned along the oblique electric field. In addition, a dielectric layer is arranged between the transparent electrode and the alignment layer.

Description

B7 V. Description of the Invention (i) The present invention relates to a liquid crystal display device using a gradient electric field. TN (Twisted Nematic) type liquid crystal display devices have been widely used, for example, as display units for personal computers. However, a potential problem of these TN-type liquid crystal display devices is that when the screen is viewed from an oblique direction, the contrast is reduced or the brightness is reversed. Therefore, there is an urgent need for a liquid crystal display device whose contrast does not decrease when viewed in an oblique direction. For example, Japanese unexamined patent applications Nos. 10-153782 and No. 10186186351 disclose that an IPS (Planar Switching) type liquid crystal display device 'does not decrease in contrast when viewed obliquely. In such a jpg type liquid crystal display device, a liquid crystal system is disposed between a pair of substrates, and one of the substrates has a first electrode and a second electrode, and a voltage is applied between the two electrodes. The other substrate is not provided with electrodes. Therefore, a lateral electric field approximately parallel to the surface of the substrate is generated between the first electrode and the second electrode. Its liquid crystal is driven by the lateral electric field. The liquid crystal display device disclosed in the aforementioned application uses a vertical alignment type liquid crystal having a positive dielectric anisotropy. When no voltage is applied, its liquid crystal is aligned in a direction perpendicular to the surface of the substrate, and when a voltage is applied, it is aligned in a direction parallel to the lateral electric field. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In the IPS-type liquid crystal display device described above, the first and second electrodes are made of thin metal strips, and extend parallel to one of the substrates. Once a voltage is applied, the power line of the transverse electric field will extend from the first electrode toward the second electrode in an arc shape. Assuming that the first electrode is located on the left side of the second electrode, the liquid crystal molecules near the first electrode will be aligned to the upper right along the power line, and the liquid crystal molecules near the second electrode will be aligned along the electrical G-scale scale. National Country of Finance (CNS) A4g (21GX297 public director ----- 4 587191 V. Description of the invention (2) The force line is aligned to the upper left. Liquid crystal molecules in the middle zone between the first electrode and the second electrode , It will be aligned along the power line in a direction parallel to the substrate surface. However, the liquid crystal molecules between the first electrode and the second electrode will be affected by the liquid crystal molecules aligned to the upper left and upper right. It is impossible to align in a direction parallel to the surface of the substrate. This unstable alignment will cause disorder. As a result, a black line will be generated between the first and second electrodes, which will reduce the transmittance. The occurrence of such disturbances depends on voltage or interference, and may cause irregular display or image retention. The object of the present invention is to provide a liquid crystal display device which has excellent viewing angle characteristics without Disorderly The liquid crystal display device according to the present invention includes a pair of substrates, a liquid crystal is disposed between the pair of substrates, a plurality of strip electrodes of each pixel are disposed on one of the foregoing substrates, and a transparent electrode is disposed on the substrate. The other substrate substantially covers the entire surface of the other substrate (at least covers its display area). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 丨 In the aforementioned structure, a single electrode and the wide transparent electrode An electric field will be formed between them. This electric field is an oblique electric field, which will extend from each type of electrode to the wide transparent electrode in an oblique direction. Therefore, when no voltage is applied to it, its liquid crystal will be perpendicular to the substrate surface When a voltage is applied, it will be aligned in a direction parallel to the oblique electric field. In this situation, almost all the liquid crystal molecules will be properly aligned along the electric field. Therefore, the disorder will not occur.

Many electric fields (electric power lines), as indicated by the arrow F0, extend obliquely from each type of electrode 22 toward the transparent electrode 18. Therefore, the liquid crystal molecules with positive dielectric anisotropy will be aligned parallel to the inclined electric field F0 when a voltage is applied to them. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs As a result, the liquid crystal molecules will be inclined to the surface of the substrate in an oblique direction and birefringent, thus changing the polarization of the incident light. Therefore, most of the liquid crystal molecules will be properly aligned along the inclined electric field without causing disturbance. The polarizing plates 26, 28 are arranged in a crossed Nicols, so when a voltage is applied, a white display will be produced. In the vicinity of the strip electrode 22, the electric field (power line) is perpendicular to the surface of the substrate, such as an arrow? Shown as 1 ^. The strip electrode 22 is made of metal, and therefore has a shielding function. Therefore, there is no problem in the operation of the liquid crystal in this part. The viewing angle characteristics of this type of liquid crystal display device are better than those of the TN type liquid crystal display device. 5A to 5C are comparative examples of a liquid crystal display device. In the fifth step, the first substrate 12 is not provided with an electrode, and only the second substrate 14 is provided with a first electrode 23a and a second electrode 23b. The liquid crystal layer 16 includes a liquid crystal of a vertical alignment type and has a positive dielectric anisotropy.

Once a voltage is applied, 'as shown in Section 5B ，, a horizontal electric field will be formed by the first- The second electrode 23b extends. The liquid crystal molecules will be aligned parallel to the horizontal electric field. However, it cannot be determined that the liquid crystal molecules in the middle position between the two electrodes 23 & 23b will follow the right or left Alignment of liquid crystal molecules, resulting in unpredictable alignment of liquid crystal molecules. Therefore, as shown in Figure 5C 囷, a disordered region D will occur in the central portion of the pixel region 10b of one of the liquid crystal display devices. The areas C are shielded by the first electrode 23a and the second electrode 23b made of metal. According to the present invention, the disordered areas D will be reduced.

FIG. 7A shows a cross-sectional view of the liquid crystal display device 10 of FIG. 6 when a voltage is applied. Opposite first and second transparent glass The glass substrates 12, 14, a liquid crystal layer 16 is provided between the first and second substrates 12, 14, and the polarizing plates 26, 28, and the like.

The first substrate 12 includes a wide or whole piece of transparent electrode 18 covering the entire surface of the first electrode 12 and a vertical alignment layer 20. The second substrate includes a plurality of first and second extending in parallel and in parallel. The group-shaped electrodes 22 a and 22 b ′ and a vertical alignment layer 24. The first and second groups of strip electrodes 22a, 22b are applied with different voltages. In this embodiment, an AC data voltage (i.e., 5 V) is applied to the strip electrodes 22a of the first group, and the same voltage as the transparent electrode 18 is applied to the strip voltage 22b of the second group. In this example, the transparent electrode 18 is supplied with a voltage (ground) that is substantially between the AC.

Description of Invention (19) Between voltage and data. In addition, the dielectric layer (insulating layer) 36 is disposed between the transparent electrode 18 and the vertical alignment layer 20. The transparent electrode 18 is disposed on the inner surface of the first substrate 12, and the dielectric layer 36 is disposed on the transparent electrode 18. Basically, the dielectric layer 36 is interposed between the transparent electrode 18 and the liquid crystal layer 16. Preferably, the dielectric layer 36 is made of an optically curable resin, a thermoplastic resin, a positive or negative anti-surname agent, a polyamino acid, or another organic resin (such as an epoxy resin, an acrylic resin, or a fluorinated resin). Or made of SiO, SiO2, SiN and other groups. In this structure, as shown in FIG. 6, when no voltage is applied, the liquid crystal molecules are aligned in a direction perpendicular to the surface of the substrate. However, as shown in Section 7 ', when a voltage is applied, an electric field (power line) is formed by the strip-shaped electrodes 22a of each first group toward the transparent electrode 18. Many electric fields (power lines), as indicated by arrow F0, extend obliquely toward the transparent electrode 18 from the modified electrodes 22a of the first group. Therefore, when a liquid crystal molecule with positive dielectric anisotropy is applied with a voltage, it will be aligned in a direction parallel to the oblique electric field knife. Moreover, a lateral or horizontal electric field FT is generated, and the strip electrodes 22a of each first group extend toward the strip electrodes 22b of each second group. This lateral electric field Ft can assist in forming an oblique electric field F0 extending from each first ping strip electrode toward the transparent electrode. In particular, in the structure shown in Fig. 2, the oblique electric field FQ decreases significantly with the horizontal distance from the strip electrode 22. However, the intensity of the oblique electric field F0 in FIG. 7 does not decrease much with the distance from the strip electrode 22a. The liquid crystal molecules will be aligned parallel to the oblique electric field F0, and applicable to the substrate surface paper size.

Description of the invention Therefore, 'most of the liquid crystal molecules will be properly aligned along the oblique electric field, and the disordered area in Fig. 5D can be avoided considerably. The dielectric layer 36 is interposed between the transparent electrodes. Between 18 and the liquid crystal layer μ, the formation of the oblique electric field F0 can be more promoted, and an excellent display effect can be achieved. The effect of the oblique electric field 36 will be described with reference to 8 and 9). Figure 9 is for explaining the operation of the dielectric layer 36. The eighth figure shows how an electric field is formed without the dielectric layer 36, and the ninth figure shows how an electric field is formed when the dielectric layer 36 is present. In .8 and 9 囷, isopotential lines are shown formed around the strip electrodes 22a. In Figure 8, the electric field is excessively concentrated In the vicinity of each of the first group of strip electrodes 22a, and the equipotential lines remain only in the liquid crystal layer 16. In the liquid crystal layer 16, the electric field will strongly tend to extend along the vertical direction of the transparent electrode 18, Therefore, the oblique electric field has a strong vector along the vertical direction, but it will not be tilted enough. Therefore, the liquid crystal will not fully display birefringence characteristics. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in Figure 9. The equipotential lines extend from the liquid crystal layer 16 to the dielectric layer 36, so the concentration of the electric field in the liquid crystal layer 16 is relatively loose. Therefore, in the liquid crystal layer 16, the vertical direction of the transparent electrode 18 The strength of the electric field extending in the downward direction will be weakened. As a result, the vector of the oblique electric field along the vertical direction will be weakened and become sufficiently inclined. Therefore, its liquid crystal molecules can be inclined sufficiently. Figure 10A shows a similar In the liquid crystal display device of the 6th digit, the dielectric layer 36 is not provided.

Description of the Invention (Printed by the Consumer Cooperative Office of the Intellectual Property Bureau of the Ministry of Economic Affairs) As the thickness of the dielectric layer 36 increases, its transmittance will increase. When the thickness of the electrical layer 36 is about 3 to 4 / zm, its transmittance is the highest, and when the thickness of the dielectric layer 36 exceeds 4 # m, its transmittance will gradually decrease. However, 'when the dielectric layer When the thickness of 36 exceeds 4 μm, the role of the entire transparent electrode is reduced. Therefore, in theory, the thickness of the dielectric layer 36 is preferably in the range of 3 β m ± 3 // m. Φ This dielectric The thickness of the dielectric layer 36 depends on its dielectric constant. If the dielectric constant of the dielectric layer 36 is in the range of 3 ± 1, the thickness of the dielectric layer 36 should be not less than 0.1 m but not more than 5 / zm. If the dielectric constant of the dielectric layer 36 is in the range of 5 ± 1, its thickness should be not less than 0.5 / ζπ1 but not more than 10 # m. In particular, if the dielectric layer 36 When the dielectric constant is about 3, its thickness should be 1 β m to 4. If the dielectric constant of the dielectric layer 36 is about 7, its normal thickness is 3 # m to 6 # m. This is determined based on the way in which the equipotential lines of the 9th line are formed. Figures 18 to 21 show various examples of the dielectric layer 36.

In this example, polyimide with vertical alignment characteristics is used as the basic material of the color filter 38 to form the above-mentioned structure. In the structure of FIG. 18, the dielectric layer 36 is required However, in the structure of Figs. 19 to 21, the dielectric layer 36 is not required. If the dielectric layer 36 is added, manufacturing steps need to be added to form the dielectric layer 36 'to form a transmission electrode. This transparent electrode 18 is connected to a lead electrode of the second substrate 14. Further, the dielectric layer 36 is likely to have the properties of a phase film as described later. FIG. 22 shows an example of the first and second strip electrodes 22a, 22b and the active substrate provided in the second substrate 14. As shown in FIG.

Moreover, the strip electrodes 22a, 22b of the first and second groups are each divided into two sub-groups of linear portions, extending in a direction of 90 degrees between the portions. Specifically, the connection electrode 22c includes a connection electrode portion 22cx extending parallel to the gate bus line 30, and a connection electrode portion 22cy extends parallel to the data bus line 32 along the center line of the pixel. This connection electrode 22d also has connection electrode portions 22dx and 22dy. The strip electrodes 22a, 22b of the first and second groups are divided into two subgroups on both sides of the connection electrode portions 22cy, 22dy. In each subgroup, the liquid crystal molecules located on both sides of each of the electrode electrodes 22a of the first group are tilted in opposite directions (No. 7), so the liquid crystals are aligned in different directions. As a result, the pixel will be divided into four regions of 2X2. With this structure, its liquid crystal molecules will be inclined in four directions, so its viewing angle characteristics will be more improved.

The common voltage is determined by assuming that the average value of the voltage VLC applied to the liquid crystal has taken into account the voltage drop. Since the liquid crystal system is moved by the AC voltage Between the first and second electrode 22a and 22b, the DC voltage component is normally not applied for a long time.

Description of Invention (32), * * In the 36A and 36Bffl, ¥ 1 The difference from 乂 2, that is, the DC voltage component applied to the liquid crystal layer 16 will decrease at any time, and will return to zero after 10 to 20 seconds. Therefore, if the insulating layer 50 is provided therein, With the presence of DC voltage components, the feasibility of causing screen image retention will also be reduced. In 36C 囷, the voltage difference between 乂 1 and 乂 2 does not decrease with time, so the screen image may be stuck. In order to avoid image stagnation, the insulating layer 50 should be provided and the following items > should be considered. (A) The time required to absorb the voltage difference between ¥ 1 and 乂 2, that is, the time when the DC voltage component is applied to the liquid crystal layer 16 to return to zero, is several seconds to hundreds of seconds. The shorter the time before the voltage difference between ▽ 1 and 乂 2 becomes zero, the less time the DC voltage component is applied to the liquid crystal layer 16. This is very beneficial to avoid the lingering image of labor. However, if the reset time is too short, the voltage retention of the liquid crystal will be reduced. Therefore, the proper zeroing time is several seconds to hundreds of seconds. 0) The voltage difference between 乂 1 and 乂 1, that is, the strength of the electric field near the alignment layer 22, is as close as possible to 0. As a result, at the boundary between the liquid crystal layer 16 and the alignment layer 22, the residual DC voltage due to ion absorption will decrease. By properly selecting the volume resistivity of the constituent materials of the liquid crystal cell, these two conditions can be satisfied.

The first and second straight parts of the first group of strip electrodes 22a are parallel to the data bus line 32. A connection electrode portion 22cq of a connection electrode 22c is connected. The drive correction electrode portion 22ml extends in a straight line to form a body with the connection electrode portion 22cq.

Part (47) of the description of the invention (referred to as the center Straight line portion) In view, the connecting electrode portion 22cq connects the central straight line portion and the straight line portion above it, but the drive correction electrode portion injury does not connect the central straight line portion and the straight line portion below it. The drive correction electrode portion 22ml forms an acute angle with a straight portion of the second group of strip-shaped electrodes 22b located below the central straight portion. The driving correction electrode portion 22ml and the linear portion of the second group of strip electrodes 22b located below it are applied with different voltages. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy In other words, one of the first and second straight portions of the first group of strip electrodes 22a is a connection electrode portion connected to the first connection electrode 22c parallel to the data bus line 32 The portion 22cq of the first connection electrode 22c will extend in a direction from the junction between the special straight portion and the connection electrode portion, and the drive correction electrode portion 22ml will converge with the data The line-parallel connection electrode portion 22cq extends in the opposite direction and ends at a position that overlaps with the closest one of the straight portions of most of the second type electrodes 22b. Therefore, the linear portion of the second group of strip electrodes 22b crosses the driving correction electrode portion 22rnl at an acute angle, but the two are applied with different voltages. As a result, the portion where the liquid crystal can be driven is increased, so that a bright display can be produced. As shown in Fig. 62, the driving correction electrode portion 22ml, when viewed from above, is projected inwardly by a protruding amount L from the connecting electrode portion 22dq of the second connecting electrode 22d. The drive correction electrode portion 22ml protrudes inward from the connection electrode portion 22dq of the second connection electrode 22d, and the straight portion of the drive correction electrode portion 22ml and the second group of strip electrodes 22b forming an acute angle therewith.

In Figures 60 and 63, a straight portion of the second group of strip electrodes 22b is connected to a connection electrode portion 22dq of a second connection electrode 22d parallel to the gate bus line, and the drive correction electrode portion 22m2 It is connected to the inside of the connection electrode portion 22dq of the second connection electrode 22d. Therefore, a straight portion of the > group of strip electrodes 22a crosses the driving correction electrode portion 22m2 at an acute angle, but the two are applied with different voltages. Therefore, the portion where the liquid crystal can be driven is increased to form a brighter display. As shown in Fig. 63, when viewed from above, the driving correction electrode portion 22m2 protrudes inwardly by an amount of L from the straight portion of the first group of strip electrodes 22a.

However, a recessed portion is formed on the inner edge of the connection electrode portion 22dq of the second connection electrode 22d, that is, where the drive correction electrode portion 22ml is located. Therefore, the drive correction electrode portion 22ml protrudes more horizontally than the connection electrode portion 22dq of the second connection electrode 22d.

The electrode 22b, and a second insulating layer 50b cover the first group of stripe electrodes 22a to which the data voltage is applied. In section 73F, the insulating layer 50 is partially removed after formation. Specifically, in this A part of the insulating layer 50 around the second group of strip-type electrodes 22b will be removed by etching. Fig. 78A is a plan view showing a portion near the second strip-type electrode 22b in Fig. 73. The insulation layer 50 includes an open portion 50X to expose the second group of strip electrodes 22b. Therefore, the horizontal electric field formed between the first group of strip-type electrodes 22a and the second group of strip-type electrodes 22b is blocked to a lesser extent by the insulating layer 50, thereby preventing the liquid crystal driving voltage from being reduced. Fig. 74 shows a modified example of the 73th LCD device. In Section 74 (i), the insulating layer 50 is partially removed after fabrication. That is, a portion of the insulating layer 50 (second insulating layer 50b) in the peripheral portion of the first group of strip-shaped electrodes 22a is removed by etching. Therefore, the oblique electric field formed between the first group of strip-shaped electrodes 22a and the entire solid transparent electrode 18 will not be blocked by the insulating layer 50, and the liquid crystal driving voltage can be prevented from being reduced. After the insulating layer 50 is made, the portion of the insulating layer 50 around the first group of strip electrodes 22a and the portion of the insulating layer 50 around the second group of strip electrodes 22b can also be effectively removed. .

5. Description of the invention (52) The transmittance is about 20%, which is significantly different from the result shown in Figure 74. It seems to reduce the driving voltage. In the liquid crystal display device shown in FIG. 72, an oblique electric field is generated and extends from the first strip-shaped electrode 22a toward the entire solid transparent electrode 18 of the opposing substrate 12. The electric field is approximately perpendicular to the transparent electrode 18 near the first group of strip-shaped electrodes 22a. Seen here, as shown in FIG. 79, at the position of the substrate 12 relative to the second group of strip electrodes 22b, the entire solid transparent electrode 18 is replaced by a third group of strip electrodes 18a. . In this way, an oblique electric field can be efficiently formed between the first group of strip electrodes 22a and the third group of strip electrodes 18a. However, in the 79th structure, if a displacement occurs between the substrates 12 and 14, the electrodes will be displaced, and the relationship between the voltage and the transmittance will be quite irregular. Fig. 80 is a sectional view showing a liquid crystal display device according to a seventh embodiment of the present invention. In this embodiment, a substrate 14 includes a first group of strip electrodes f 22a and a second group of strip electrodes 22b, and another substrate 12 includes the entire solid transparent electrode 18, and a third group of The strip electrode 18a is opposite to the strip electrode 22b of the second group. In detail, only the portion of the transparent electrode 18 includes a high-resistance electrode portion 18x, and the portion where the transparent electrode 18 and the third group of strip electrodes 18a overlap each other is a low-resistance electrode portion Made of 18y. The transparent electrode 18 is made of ITO sputtering, for example, at a thickness of 200 to 300 A, and is heat-treated so as not to be removed by the etching solution. Alas, the third group of strip-shaped electrodes is sputtered to a thickness of, for example, 2000 A, and is etched using a cover.

Description of the invention (53) When a voltage is applied, its charge will be stored in the bottom resistance electrode part first. 18y, therefore, an electric field will be formed between the low-resistance electrode portion I8y and the first group of strip electrodes 22a, and the liquid crystal will initially operate based on this electric field. In fact, the potential of the high-resistance electrode portion 18x is equal to the low-resistance electrode portion 18y. Therefore, after a period of time, its charge is also stored in the high-resistance electrode portion 18x. In other words, an electric field will be formed in the range of the liquid crystal reaction. Therefore, the 80th LCD device can be operated with the same low driving voltage as the 79th LCD device. The liquid crystal display device shown in FIG. 8 includes the solid transparent electrode 18 as a whole. Therefore, if there is any displacement between the substrates, the relationship between the voltage and the transmittance will not be changed significantly. Circles 81 to 84 show modified examples of the liquid crystal display device of FIG. 80. As shown in FIG. 81, these modified examples use a single-type structure or a net-like structure to replace the entire solid transparent electrode, which includes most of the transparent bars with the same resistance, and constitutes a high-resistance electrode portion 18χ and A low resistance electrode portion 18y. The low-resistance electrode portion 18y is represented by a thick line, and the high-resistance electrode portion 18x is represented by a thin line. An example is shown in sections 82 and 83, where the high-resistance electrode portion 18x and the low-resistance electrode portion 18y It consists of a strip-shaped straight structure. The thin line structure is provided so as to cover the first group of strip electrodes 22a, and the structure shown by the thick line is provided so as to be opposed to the second group of strip electrodes 22b. The thick line is preferably as wide as the second group of strip electrodes 22b. Specifically, the thick line can be effectively set to a width of the second group of electrodes 22b which is not less than half but not more than twice.

Printed by the Consumer Cooperatives of Xihui Property Bureau of the Ministry of Economic Affairs, No. 84 (i) shows an example in which the high-resistance electrode portion 18χ and the low-resistance electrode portion 18y are composed of a linear network structure. In Figs. 83 and 84, a portion "above the wavy line" indicates a case on the opposite substrate, and a portion below the wavy line indicates a case on the TFT substrate. The portion corresponding to the second group of strip-shaped electrodes 22b having a wide and thick strip-shaped electrode is set to have a low resistance. In the space between them, there are fine strip-shaped electrodes, whose electric resistance is high, so that electric charges are not stored immediately, and an electric field cannot be easily formed. On the other hand, in the mesh linear structure shown in FIG. 84, an electric field can be formed more uniformly than the strip linear structure of 83 直线. In the high-resistance electrode portion 18x, the width of the strip-like or mesh-like linear structure is not greater than 3 # calendar, while in the low-resistance electrode portion 18y, the strip-like or mesh-like linear structure has a length of not less than 3 # m width.

The liquid crystal display device includes first and second substrates 12, 14 (see, for example, the first circle), and is fixed to each other by a peripheral seal 66. The peripheral seal 66 has a liquid crystal injection hole 68 at one end, and is sealed after the liquid crystal is injected. The liquid crystal is injected through the injection hole 68, and when it flows from the injection hole 68 to the far end, the impurities flowing out of the alignment layer will be concentrated at the other end away from the injection hole 68 along with the liquid crystal flow. Therefore, a region 70 far from the liquid crystal injection hole 68 may form a display failure region due to a decrease in the voltage holding ratio.

Moreover, a black matrix 72 covers the area 70 away from the injection hole 68, so the special area is set as a non-display area. The dielectric layer 36 is made of PC403 resin manufactured by JSR and has a thickness of up to 5em. The insulating layer is made of SiN. The liquid crystal layer 16 has a thickness of 4 # m, and the size of the chamber space of the region 70 away from the injection hole 68 is about 8 # m. Therefore, the width of the region 70 far from the injection hole 68 can be reduced from 4 mm to 2 mm. Therefore, the area 70 far from the injection hole 68 can be covered by the black matrix 72 without changing the area of the display area.

Fig. 91A shows four pixels arranged vertically. It is assumed that pixel a is the person who has just been written, pixel B is the person who is being written, pixel c is the person who will be written to the next data, and pixel D is the person who will be written after C. Profiler. In Figures 88 to 90, the gate bus line 30 is marked with GiSG5 _, the data bus line 32 is marked with 〇 丨 and D2, and the TFTs are shown with TFT ^ TFT4: 4. The second type electrode 22b is marked as follows. Marked. In this liquid crystal display device, many gate bus lines Gi, g2, etc. are arranged in a vertical direction, and at the same time point as the vertical synchronization signal, a scanning signal is sequentially fed from top to bottom. The picture element sent into the scanning signal is sent into the data signal through data bus lines D !, D2, etc., and a specific display data can be written in a specific picture element. For example, to write data in pixel B, a + 15V pulse signal voltage (scanning signal) will be applied to the gate bus line g2 to turn on the signal for a predetermined length of time. On the other hand, when the Df2 is 011, the data bus line 01 will be supplied with a voltage of _5V to + 5V as display data.

Description of the invention (59) Signals in the range of ± 5V) are written in the first electrode. At the same time, in the pixels A and D, since the gate bus lines 〇1 and 〇4 are both _i0V, so what? Ding 1 and Ding? Ding 4 will all be closed. Therefore, the display data sent to the data bus line Di will not be written into the pixels A and D. On the other hand, in pixel C, the inter-electrode voltage of TFT3 is ov. Therefore, when the voltage of the display data applied to the data bus D1 is negative, TFT3 will be turned on and the display data will be unnecessary. Ground is written to the first electrode. However, during the next vertical synchronization signal, the display data is written into the pixel C. Even when the display data is written into the pixel B, the display data is erroneously written into the pixel C, but during the next vertical synchronization signal, the correct display data is written into the pixel c. Therefore, the shadow cell of its erroneous write operation can be almost ignored. After the operation of writing the display data into the pixel B is completed, during the next vertical synchronization signal, the gate bus line A will be applied with a voltage of-丨 0V, and the gate bus line G3 will be applied with + A voltage of 15V is applied to the gate bus line G4. As a result, the TFL of the pixel B is turned off, and the first-type electrode h becomes a so-called floating state. At the same time, although the voltage of the second strip electrode q is changed from 0V to · 10v, an electric field having an intensity corresponding to the display data written in the first strip electrode S2 will be generated in the first strip electrode 1 and the first strip electrode q. One type of electrode C: between 2. Since the first type electrode S2 is floating, this state is maintained. Therefore, the liquid crystal molecules of pixel B will be aligned with the direction and intensity corresponding to the electric field to determine the transmittance of pixel B. The electric field strength between the first type electrode S and the second type electrode q is maintained until the gate bus line G2 forms 0V.

Description of the Invention (60) In this embodiment, the first The voltage difference between the stripe electrode 22a (Si, S2 ..., etc.) and the second stripe electrode 22b (G1, G2, etc.) will change during the data writing operation and during the data retention period. . However, for example, if it has 600 gate bus lines, the same voltage difference will be kept fixed within the time equivalent to 598> 600 of one frame period. Therefore, because the first type electrode 22a (Si, S2 ·· ··· etc.) The deterioration in display quality caused by the voltage difference between the second electrode 22b (Gi, G2, etc.) can be ignored. According to the liquid crystal display device of this embodiment, the second type electrode 22b is connected to the gate bus line 30, so the common bus line required in the conventional technology (for example, the one marked as 40 in FIG. 20), It is no longer necessary to maintain the fixed potential of the second strip electrode 22b. Therefore, the portion of the pixel area that can be used for display will be relatively increased, which can increase the aperture ratio. In this way, brightly displayed and high-contrast images can be formed. Moreover, according to this embodiment, the second type electrode 22b is partially > the data bus line 32 is overlapped, so there is an advantage that the second type electrode 22b and the data bus line 32 are not overlapped. There is light leakage. Preferably, the first and second strip electrodes 22a and 22b are provided as upper-layered conductive members. Alternatively, the second strip-type electrode 22b may be made into a lower-layer guide. If the second-type electrodes 22b are made into a lower-layer conductive member, the second-type electrodes 22b are preferably provided to partially overlap the data bus line 32. This will prevent light leakage from occurring in the gap between the second type electrode 22b and the data bus line 32.

Description of the invention (67) Width W1 Is 4 # m, and the width W2 of the black matrix 80 is set to 8m. A blue color filter 82B, a red color filter 82R, and a green color filter 82G are provided on the glass substrate. The inner surface of 12. In this example, for example, the blue color filter 82B is provided in the pixel region of the 3nth row (n = 1, 2 ....), and the red color filter 82R is provided in In the pixel region of the 3n + l row, the green color filter 82G is set in the pixel region of the 3n + 2 row. The width W4 of these color filters is 110 # m. It is shown that the color filters 82B, 82R, 82G, etc. extend to adjacent pixels under the black matrix 80. Specifically, under the black matrix 80, the blue and green color filters 82B, 82G Will overlap each other, or the blue and red color filters 82B, 82R overlap each other, or green It overlaps with the red color filters 82G and 82R.

In this particular example, the thickness of these color filters 82B, 82R, 82G is assumed to be 1 / zm. Please refer to FIG. 99 for the system. The effect of this embodiment will be explained. In the liquid crystal display device, the alignment direction of the liquid crystal molecules is determined by the distance between the first strip electrode 22a and the second strip electrode 22b. Electric field control. The alignment direction of liquid crystal molecules exists between the second type electrode 22b and the data bus line 32 on its left side, and between the second type electrode 22b and the data bus line 32 on its right side, However, it cannot be controlled by the electric field between the first stripe electrode 22a and the second stripe electrode 22b. Therefore, the light entering the liquid crystal layer through the gap (about 2 / zm wide) between them may pass through Leaked on the opposite side. 70 This paper size applies to China National Standard (CNS) A4 210X297 mm) 587191 A7 B7 V. Description of the invention (68) In this embodiment, two different color filters (color filters 82R, 82G in Fig. 99) will be weighted under the black matrix 80 *. Therefore, if light entering from the bottom surface of the glass substrate 14 is to leak through the glass substrate 12, the specific bubble leakage light will follow the path shown by the arrow No. 99 囷. Specifically, the light entering the liquid crystal layer through the gap between the second type electrode 22 b and the data bus line 32 passes through the overlapping portion of the filter materials 82R and 82G, and is on the surface of the black matrix 80. reflection. The reflected light passes through the overlapping portions of the color filters 82R and 82G, and is reflected on the second electrode 22b. The reflected light passes through the color filters 82R and 82G and is projected on the glass substrate 12. Under this condition, the leaked light will pass through the overlapping portions of the color filters 82R, 82G three times. The cold cathode ray tube usually used as the bottom light of the liquid crystal display device has a high peak when the wavelength corresponds to red, green, and blue, and the light passing through the red color filter 82R may be absorbed in green or blue. Among the color filters 82G and 82B. In the same way, the light passing through the green color filter 82G may be absorbed in the red or blue color filters 82R, 82B, and the light passing through the blue color filter 82B may be absorbed in the red or blue colors. Among the green color filters 82R and 82G. Therefore, in the liquid crystal display device of this embodiment, the intensity of the leaked light is considerably reduced, and a reduction in display quality can be avoided.

Description of the invention (69) 4 · 3, and the brightness of the resin black matrix is about 1.6. The brightness of this embodiment A is very low 0.1 or less. This clearly shows that this embodiment is very effective in reducing crosstalk. As described above, this embodiment exists in the black of the metal or metal compound.

The color matrix 80 is characterized in that it can block light between the pixel region and the color filters 82R, 82G, and 82B, and allows each pixel region to determine the color of transmitted light. Another feature is that the color filters 82R, 82G, 82B, etc. will extend from a pixel region across the black matrix 80 to adjacent pixel regions, and the black matrix 80 will be covered by at least two color filters, and The width W3 of the overlapping portion of the two color filters is larger than the width W2 of the black matrix. In this configuration, since at least two color filters are stacked on the black substrate, the amount of light reflected on the black substrate can be considerably reduced. The overlapping parts of the color filters are used as a part of the black matrix, so crosstalk can be prevented from being induced by the reflection of the black matrix, and additional manufacturing steps must be avoided. This embodiment is also characterized in that it can be applied not only to a liquid crystal display device having first and second strip electrodes 22a, 22b, but also to a TN type liquid crystal display device having an auxiliary capacitor electrode made of metal. In a liquid crystal display device, pixels having the same color of color filters are juxtaposed in a vertical direction. The color filters are strips of red, blue, and green, and the overlapping portions of the color filters are parallel. At the gate bus. On the other hand, if the liquid crystal display device has first and second strip-type electrodes 22a, 22b,% by extending the overlapping portion of the color filters over the second strip-type electrode, the black matrix Crosstalk caused by reflections above can be more reliably prevented.

Description of the Invention (70) 107 and 108 囷 can be used to explain the generation of crosstalk. For example, if a white rectangle is displayed on the black background, a white band will be generated above and below the white rectangle (the oblique line in the figure), as shown in Figure 107. This artifact is particularly noticeable when viewing the image from an oblique direction. As shown in FIG. 108, this phenomenon occurs because the light passing through the gap between the second type electrode 22b and the data bus line 32 penetrates the liquid crystal display device. > Assuming that the entire screen is all black, the voltage of these data bus lines 32 is substantially equal to the second type electrode 22b. The liquid crystal between the data bus lines 32 and the second type electrode 22b is not subjected to an electric field, so that no light leaks. Conversely, if a white rectangle is displayed on a black background, a voltage is applied to the data bus lines, so an electric field will be generated between the second type electrode 22b and the data bus line 32, that is, when displaying the Above and below the white rectangle. Therefore, its liquid crystal molecules will be aligned along this electric field. As shown in FIG. 108, the polarized light entering the liquid crystal layer from the bottom surface of the substrate 14 will be reflected on the surface of the black matrix 80, and then reflected on the surface of the second strip electrode 22b, and pass through the color filter 82 and glass. Substrate 12. This leaked light causes the portions that should appear black to form slightly white portions. This phenomenon is called crosstalk. To avoid crosstalk, a resin mixed with a black pigment can be used to form the black matrix. The black matrix made of this resin has a very low light absorption rate, and therefore does not have a sufficient effect of preventing light leakage, but may cause a problem that the overall contrast becomes low. In another method, a resin black matrix is coated on a metal black matrix.

On the other hand, the source I electrode 34s extends parallel to the gate bus line 30 and is connected to the two first strip electrodes 22a. A SiN protective film (insulating film) 50b is provided above the upper conductive layer. The upper conductive layer is provided with a data bus line 30, a drain electrode 34d, a source electrode 34s, a first type electrode 22a, and an auxiliary capacitor electrode 23. An alignment layer 24 having a thickness of 500 A is provided on the protective film 50b. The surface of the alignment layer 24 is rubbed in a direction (e.g., in a direction of 75 ° or 34 °) that is substantially perpendicular or parallel to the first strip-shaped electrode 22a. According to this embodiment, the alignment layer 24 has a volume resistivity of about 101 G to 1 OUQm. An example is an alignment layer using a polyamino group. The glass substrate 12 is also provided with an alignment layer 20 having a thickness of 500A. The surface of this alignment layer 20 is also subjected to rubbing treatment in the same direction as the alignment layer 24. However, the alignment layer 20 is preferably made of a material having a higher volume resistivity than the alignment layer 24. In this embodiment, the volume resistivity of the alignment layer 20 is about 1013Ω cm. It is an alignment layer that can be made using soluble polyimide. An example is polyimide with a five-ring ring provided by JSR. Even using a polyurethane-based alignment film, by setting a high burning temperature, its paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) --------- ^ --- --- II ------ ^ (Please read the notes on the back before filling out this page) 77 587191 A7 B7 V. Description of the invention (75) The characteristics of holding voltage can also be improved. In addition, by using an inorganic material such as a silicon-based silicon lake bonding agent (OA-003, etc.) manufactured by Nissan Chemical Co., Ltd. as an alignment layer having a high voltage holding capability, excellent characteristics can be achieved . In addition, this embodiment uses a liquid crystal having a bulk resistivity close to the alignment layer 24. An example of the liquid crystal is one of the CN (t) groups and has a volume resistivity of about 101 GQcm. In the above configuration of this embodiment, the substrate 14 uses an alignment layer 24 with a low bulk resistivity. The liquid crystal 16 and the alignment layer 24 have almost the same volume resistivity. Therefore, it is possible to prevent the charge from staying between the alignment layer 24 and the liquid crystal 16. In this method, the phenomenon that charges do not easily accumulate in layer boundaries with almost the same 鳢 resistivity is widely known in the field of electromagnetics. The alignment layer 20 on the substrate 12 has a large ship resistivity, and therefore has a high voltage holding ratio. As a result, the display data written between the first type electrode 22a and the second type electrode 22b is maintained for a long period of time, and deterioration of display quality can be avoided. Here, the research results of the liquid crystal display device according to this embodiment with or without combustion will be described in comparison with a reference example. The liquid crystal display device according to this embodiment and the reference example has the first one. The structure shown in Fig. 5 was fabricated using an alignment layer having a volume resistivity shown in Table 1 below and a liquid crystal. In the liquid crystal display devices of this embodiment and the reference example, a white rectangular image was displayed on a black background for 48 hours. After that ‘grey (level 16 is displayed on level 64) is displayed on the entire screen (please read the precautions on the back before filling out this page)

The brightness difference between the two parts is shown in Table 1 below in%.

Printed by the Intellectual Property Bureau employee consumer cooperative of the Ministry of Economic Affairs It can be seen from iL that in the first and second embodiments, ρ is particularly low. When the liquid crystal having the same volume resistivity as that of the alignment layer 24 is used, image retention is very low by only 3%. On the other hand, the first reference example basically has a structure similar to that of a conventional liquid crystal display device, and has a high image retention of 20%. In general, a TN-type liquid crystal display device uses an alignment layer having a high volume resistivity. This is to improve its voltage retention. However, even if there is a high voltage retention rate, if image retention occurs due to charge stagnation between the alignment layer and the boundary of the liquid crystal, the display quality will be significantly reduced. In view of this, according to the actual target example, the volume resistivity of the alignment layer 24 provided on the glass substrate 14 having the first stripe type electrode 22a and the second stripe type electrode 22b is reduced. Under this condition, the volume resistivity of the alignment layer 20 on the glass substrate 12 will be relatively south, so the deterioration in display quality caused by the decrease in the voltage holding ratio will be avoided. The results of the voltage retention studies will now be explained. As shown in Section 106 圊, two glass-based threads with driving electrodes 88a and 8 flutter. This paper is sized to the Chinese National Standard (CNS) A4 (210X297 mm).

5. Description of the invention (77) The plate is prepared, and the alignment layers 89a and 89b are provided on the electrodes 88a and 88b, respectively. The two glass substrates are arranged in parallel with each other so that the electrodes 88a and 88b are opposed to each other, and the liquid crystal 16 is encapsulated between the glass substrates. The alignment layers 89a, 89b have the volume resistivity shown in the following table. A voltage is applied between the electrodes 88a and 88b, and the voltage holding ratio is measured. After a voltage of 5V is applied between the electrodes 88a and 88b for a period of time (16ms), the voltage will be measured and expressed in% as the voltage holding rate.

This is compared with the volume resistivity of conventional liquid crystal display devices. It is 10ΐ3Ως: the aligning layer of π1 has a voltage holding ratio of about 98.5%. According to the present invention, an adjusting layer with a low voltage holding ratio is used in the first layer electrode and the second electrode. On the substrate (glass substrate 14), the two voltage holding ratio adjustment layers are used on the opposite substrate (glass substrate 12) to avoid the image retention phenomenon of the liquid crystal display device. As mentioned above, the second strip type The structure in which the electrodes are connected to the gate bus lines will improve the aperture ratio, and can form a high-contrast bright image display. These gate bus lines are applied with a reference voltage to determine the size of the paper available for writing in China. standard( CNS) A4 size (210X297 mm) 80

Description of the invention (78) The potential of the second type electrode entered in the display data, and the first voltage supply to turn on the thin film transistor, and the second voltage supply to turn off the thin film transistor at an appropriate point, so that the The liquid crystal display device of the second type electrode connected to the gate bus line can be driven. In addition, at least two color filters are stacked on each other on a black substrate made of a metal or a metal compound, and the width of the overlapping portion of the color filters is set to be greater than the width of the black substrate. Therefore, it is possible to prevent light leakage and avoid deterioration of display quality which may be caused by crosstalk. The first alignment layer provided on the first substrate and the second alignment layer provided on the second substrate have different electrical characteristics, so it can avoid image retention caused by the charge cap stored on the adjustment layer. At the same time, it can cause an excellent voltage retention and high-quality image display.

The liquid crystal 16 is added with a spin agent that determines the direction in which the liquid crystal molecules twist. The glass substrate 14 includes first and second strip electrodes 22a, 22b. These electrodes 22a and 22b are arranged parallel to each other.

Description of the invention (79) Chromium (Cr), aluminum (A1) or similar metals, etc. The first and second strip electrodes 22a, 22b are covered by an insulating film 50 made of silicon oxide or silicon nitride. A vertical alignment layer 24 is disposed on the insulating film 50. The vertical alignment layer 24 is made of, for example, polyamic acid or polyimide having an alkyl group as a side chain. The first type electrode 22 a is sent from a data bus line 32 to a data through a TFT 34. The gate of the TFT 34 is fed with a scanning signal via a gate bus line 30. The second electrode 22b is connected to the common bus line 40. The glass substrate 12 is provided with a horizontal alignment layer 90. The horizontal alignment layer 90 is made of a linear soluble polyimide, and its surface is subjected to rubbing treatment in a direction approximately perpendicular to the first and second strip electrodes 22a, 22b. Further, a polarizing plate 28 is provided outside the substrate 14, and a polarizing plate 26 is provided outside the substrate 12. The polarizing plates 26, 28 are arranged such that their polarization axes are vertical (intersecting Nicols) or parallel (parallel Nicols). In this case, the polarization axis of the polarizing plate 26 is set to be perpendicular to the directions of the first and second strip electrodes 22a, 22b (the directions indicated by arrows in FIG. 112), and the polarizing plate The polarization axis of 28 is set parallel to the directions of the first and second strip electrodes 22a, 22b. With a liquid crystal display device having this structure, as long as a voltage is applied between the first and second strip electrodes 22a, 22b, as shown in FIG. 112, the liquid crystal molecules 16 thereof will be aligned perpendicular to the substrate 14. Alignment of the alignment layer 24, and alignment along the rubbing direction of the alignment layer 90 on the substrate 14, so that the liquid crystal molecules 16 gradually tilt from the vertical direction to the horizontal, (this paper The scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 82 587191 Printed by the Ministry of Economic Affairs, Intellectual Property Office, Industrial and Consumer Cooperatives _ A7 _ _B7 _ ^ _ Description of the invention (80) View from substrate 14 toward substrate 1) While gradually twisting in the direction determined by the spin agent. The polarized light entering the liquid crystal layer from the bottom surface of the glass substrate 14 through the polarizing plate 28 passes through the liquid crystal layer, and its polarization axis is gradually twisted in the twisting direction of the liquid crystal molecules 16 and penetrates the polarizing plate 90 in total. That is, in this liquid crystal display device, if no voltage is applied between the electrodes 22a and 22b, a bright display can be obtained. On the other hand, when a voltage is applied between the electrodes 22a and 22b, as shown in FIG. 113, the liquid crystal molecules 16 are aligned along the direction of the electric field, that is, perpendicular to the direction of the electrodes 22a and 22b. In this case, the polarization axis of the polarized light entering the liquid crystal layer from the bottom side of the substrate 14 through the polarizing plate 28 will not be changed by the liquid crystal layer, so it will be shielded by the polarizing plate 26. In other words, if a voltage is applied between the electrodes 22a, 22b, a dark display can be obtained. In this embodiment, the electric field generated by the voltage applied between the electrodes 22a, 22b can eliminate the twist of the liquid crystal. During this process, the alignment direction of the liquid crystal molecules near the horizontal alignment layer 90 and pinned by the horizontal alignment layer 90 will be consistent with the direction of the electric field, so the alignment of the liquid crystal molecules will not be pinned. Disturbed. Therefore, it is even possible to align the liquid crystal molecules 16 along the direction of the electric field with a lower voltage, thereby reducing the driving voltage. In addition, since the liquid crystal molecules 16 between the electrodes 22a and 22b are all aligned in one direction, no disturbance occurs and a bright image can be displayed.

In this embodiment, a horizontal alignment layer 92 is disposed on the substrate 14 and a vertical alignment layer 20 is disposed on the substrate 12. The surface of the horizontal alignment layer 92 is rubbed in a direction substantially perpendicular to the electrodes 22a, 22b. In a liquid crystal display device having this structure, the liquid crystal molecules 16 near the horizontal alignment layer 92 on the substrate 14 are substantially perpendicular to the electrodes 22a, 22a, 22 when no voltage is applied between the electrodes 22a, 22b. The direction of 22b (that is, the direction of friction) is aligned, as shown in FIG. 119. On the other hand, the liquid crystal molecules 16 near the vertical alignment layer 20 on the substrate 12 are aligned in a direction perpendicular to the alignment layer 20. When the liquid crystal molecules 16 'interposed between the substrates 12 and 14 are advanced from the substrate 14 toward the substrate 12, the liquid crystal molecules 16' will gradually twist in a direction determined by the spin agent, and at the same time gradually rise from the horizontal direction to the vertical direction.

Liquid crystal molecules in the vicinity of the horizontal alignment layer 92 will be strongly restrained by the alignment layer 92. However, in this embodiment, the pinching direction is substantially the same as the alignment direction when the liquid crystal molecules are applied with a current. Therefore, according to this embodiment, the liquid crystal molecules can be aligned with the direction of the electric field at a low voltage.

It will be rubbed in one direction. After the horizontal alignment layer in area b is covered with an impedance film, it will be rubbed in the direction opposite to area A. In this way, since the A region and the B region are rubbed in different directions, the liquid crystal molecules 16 in the regions A and B will be tilted in the opposite direction in advance, as shown in FIG. 121, to complete the so-called segment Alignment.

The same components in FIGS. 122 and 123 as those in FIG. 110 are denoted by the same reference numerals, and will not be described in detail. Figure 122A shows a state where no voltage is applied between the electrodes, and Figure 123 shows a state where a voltage is applied between the electrodes.

On the contrary, if a voltage is applied between the first and second electrodes, an electric field is generated in a direction parallel to the substrates, and the liquid crystal molecules are aligned along the electric field. In this case, the polarized light entering the liquid crystal layer passes through the liquid crystal layer without changing the direction of its polarization axis.

Description of the invention (87) The liquid crystal molecules can be adjusted along the direction of the electric field at a lower voltage While reducing the driving voltage of the liquid crystal display device. In addition, the electric field generated between the first and second electrodes eliminates the twisting of the liquid crystal molecules, and prevents the display from being disturbed and causing a bright display. The d / p ratio between the thickness d of the liquid crystal layer and the natural twist pitch p of the liquid crystal is most in the range of 0.125 to 3. If the d / p ratio is less than 0.125, the transmittance is reduced and a bright image cannot be produced. Conversely, if the d / p value is greater than 3, its alignment may be disturbed or reflected in the liquid crystal, and a good image cannot be produced. The larger d / p range is 0.2 to 3, and the better range is 0.35 ± (κ1. The birefringence Δη of the liquid crystal and the thickness of the liquid crystal layer (1 Δη (1 is preferably at Within the range of 0 · 7 ± 0 · 2.

Fig. 124 is a plan view showing a liquid crystal display device according to still another embodiment of the present invention, and Fig. 125 shows an equivalent circuit of the liquid crystal display device of Fig. 124. Fig. 126 is A cross-sectional view of the liquid crystal display device of Fig. 124. The liquid crystal display device includes a semi-transparent glass substrate 12, a glass substrate 14 is disposed opposite the glass substrate 12, and a liquid crystal 16 is inserted into the glass substrates 12 and 14. The glass substrate 12 has a vertical alignment layer 20. The glass substrate 14 includes a reflective layer 94, first and second parallel strip electrodes 22a, 22b, and a vertical alignment layer 24. In FIG. 126 , The first type The electrodes 22a and the second strip electrodes 22b are alternately arranged with each other. If a voltage is applied between these electrodes, horizontal electric fields E1 to E3 will be generated. In this example, a first strip electrode 22a and The part between the left and right second type electrodes 22b, that is, the part shown by the dot chain line 52, represents a pixel. The boundary of the adjacent pixel area is located at > The second type electrode The center of 22b. The first and second strip electrodes 22a and 22b alternately arranged at the same interval. Therefore, if a voltage is applied to the adjacent first strip electrode 22a at the same time, the entire pixel area includes adjacent The alignment direction of the liquid crystal at the boundary between the pixel regions will change, so the liquid crystal at the boundary portion of the adjacent pixel regions will be constantly driven to achieve a high contrast. The reflective layer 94 is provided under the first and second strip electrodes 22 a and 22 b of the glass substrate 14. The light entering the liquid crystal layer from the top of the 124th page will be reflected by the reflective layer 94. On the other hand, the data bus lines 32 and the TFT 34 are provided under the second type electrode 22b. This is to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) for this paper size. I Assemble (please read the precautions on the back before filling this page) 91 587191 A7 B7 The second strip electrode 22b is used to screen the thin film transistor to prevent incident light from irradiating it, thereby reducing the light leakage current of the TFT 34. The data voltage applied to the data bus 32 will be transmitted from the data via the contact hole 96.

The source electrode of the I TFT 34 is applied to the first strip electrode 22a, and horizontal electric fields E1 to E3 are generated. The p-type liquid crystal molecules that are not aligned in the vertical direction but applied with voltage will be aligned in the horizontal direction by the electric fields E1 to E3. Therefore, the polarization direction of light passing through the liquid crystal layer and reflected by the reflective layer 94 is rotated by 90 degrees. Therefore, by supplying linearly polarized light passing through the polarizing plate into the liquid crystal layer, the reflected light can be converted. In 125th, the first and second type electrodes 22a and 22b and the liquid crystal therebetween are equivalently represented by capacitors Cl to C4. Fig. 126 shows a state where no voltage is applied between the first and second strip electrodes 22a and 22b. A reflective layer 94 is disposed on the glass substrate 14, and the first and second strip electrodes 22a, 22b are disposed on the reflective film 94 through an insulating layer 50c. Further, a vertical alignment layer 24 is provided on the first strip-type electrode, the second strip-type electrode, and the insulating film 50c. In Figure 126, the data buses 32 are not shown. On the other hand, a polarizing plate 26 is provided on the outside (display surface) of the glass substrate 12, and a vertical alignment layer 20 is provided on the inside of the glass substrate 12. A P-type liquid crystal 16 is interposed between the glass substrates 12 and 14. If no voltage is applied between the first and second strip electrodes 22a, 22b, the vertical alignment layers 20, 24 will align the liquid crystal 16 in a direction perpendicular to the glass substrates 12, 14. When no voltage is applied to The first type electrode 22a and the second type electrode 22b The paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm)

In the description of the invention (90), the alignment direction of the liquid crystal will remain vertical, and the polarization state of the incident light 111 will remain unchanged. As a result, the light 111 passing through the polarizing plate 26 is reflected on the reflective layer 94 and passes through the polarizing plate 26 again. In other words, when no voltage is applied, the display on the liquid crystal panel is white. Fig. 127 is a diagram for explaining the operation when a voltage is applied to the liquid crystal display device. When a voltage is applied between the first strip-type electrode 22a and the second strip-type electrode 22b, the p-type liquid crystal 16 is inclined in a horizontal direction. In this example, > its liquid crystal 16 is tilted horizontally and its function is similar to a λ / 4 plate, and the polarization direction of the incident light can be rotated by 90 degrees, which in turn is the wavelength of the incident light. Therefore, the light 111 that has passed through the polarizing plate 26 and reflected on the reflective layer 94 cannot pass through the polarizing plate 26 because its polarization plane has been rotated by 90 degrees. In this way, when a current is applied, the liquid crystal display device displays black. As described above, according to the liquid crystal display device of the present invention, all the first stripe electrodes 22a and second stripe electrodes 22b need is to generate an electric field in the horizontal direction, so it is not necessary to face the glass through the liquid crystal layer. The substrate 14 > is provided with a counter electrode on the glass substrate 12. Therefore, the glass substrate 14 is provided with only the first type electrode 22a, the second type electrode 22b, the data bus line 32, the gate bus line 30, the TFT 34, and the like. Therefore, the manufacturing process of the liquid crystal display device can be simplified. Fig. 128 is a plan view showing a modified example of the liquid crystal display device of Fig. 124, and shows a structure in which each pixel region is driven by two first strip-type electrodes 22a. The data voltages supplied to the data bus lines 32 are applied to the first type electrode 22a via the TFT 34, which has a gate bus line 30 to which a gate voltage is supplied.

Description of Invention (91) The second electrode 22b is applied with a predetermined voltage. Because the voltage difference between the electrode 22a and the second strip electrode 22b, an electric field will be generated therebetween. This electric field will control the alignment direction of the liquid crystal 16. According to this embodiment, the liquid crystal 16 in a pixel region corresponding to a reflective layer 94 is moved by three second type electrodes 22b and two first type electrodes 22a arranged therebetween. Therefore, the voltage applied to a predetermined electric field to the liquid crystal 16 can be reduced, thereby saving power consumption. The reflective layer 94 is made of a metal or an insulating material, and is provided under the first and second strip electrodes 22a and 22b. According to this embodiment, in order to facilitate the formation of the data bus lines 32, the reflective layer 94 is partitioned by the boundary portion of the pixel. Specifically, the data buses may be provided at the boundary portion of the pixel, in which the reflective layer 94 is divided. If the reflective layer 94 is made of a metal, it is preferably an aluminum film or similar high reflectivity metal. If it is an insulating material, a pigment-containing acrylic resin may be used. On the other hand, if it is an insulating material, red, green, and blue pigments can be used to form the reflective film 94 as an alternative color filter, thereby simplifying the structure of the color liquid crystal display device. Section 129th is a cross-sectional view taken along line 129-129 of FIG. 128. The reflective layer 94 is electrically insulated from the first and second strip electrodes 22a and 22b by an HRC-001 insulating layer 50c made by Japan Synthetic Rubber Company, for example, having a thickness of 1 to 10 #m. Therefore, an aluminum film or similar highly reflective film can be used as the reflective layer 94. If the reflective layer 94 is made of a conductive material such as an aluminum film, the data bus lines 32 will be surrounded by the reflective layer 94 and the first type electrode 22b, so the data bus lines 32 leak (please first Please read the notes on the back and fill in this page.)

Description of the invention ( 92) The leaked electric field can be shielded by the conductive material. As a result, the liquid crystal 16 will not be disturbed by the electric field leaked by the data bus line 32, and the display contrast can be improved. * These vertical alignment layers 20 and 24 are used to align the liquid crystal 16 in a direction perpendicular to the glass substrates 12 and 14 when no voltage is applied. RN-783 made by Nissan Chemical is an example of a usable material. The TFT 34 and the data bus line 32 are provided under the second type electrode 22b. Therefore, the TFT 34 is shielded by the opaque second strip electrode 22b, and the light leakage current of the TFT 34 can be reduced. Moreover, the data bus lines 32 and the TFT 34 which are not applied to the display are provided under the second type electrode 22b. Therefore, almost the entire surface of the panel can be covered by the reflective layer 94 and the second type electrode 22b. Therefore, it can increase the reflection area of the entire liquid crystal display panel. Specifically, the first strip-type electrode 22a and the second strip-type electrode 22b are a metal conductor such as a metal, and are shaped like a reflector. Therefore, they are used in combination with the original reflective layer 94 to improve the reflectivity of the liquid crystal display panel. At the same time, since the second type electrode 22b series is disposed above the boundary of the adjacent reflective layer 94, so that light can also be reflected at the boundary of the reflective layer 94, the reflective area of the panel will be increased. As described above, when a voltage is applied between the first and second strip electrodes 22a and 22b, the p-type liquid crystal 16 will be inclined in the same direction as the electric field, that is, perpendicular to the first and second strip electrodes. The electrodes 22a and 22b are parallel to the glass substrates 12,14. In this example, the polarizing plate 26 is disposed at a position such that its transmission axis or absorption axis is parallel to the glass substrates 12, 14 and is perpendicular to the directions of the first and second strip electrodes 22a, 22b. At a 45-degree angle.

Description of Invention (93) Therefore, the polarization direction of the light passing through the liquid crystal 16 to which a voltage is applied Order rotation 90. . Moreover, the hysteresis And of the product of the refractive index anisotropy Δη of the liquid crystal 16 and the cavity gap d, when a voltage is applied, will be adjusted to be equal to ηλ / 4 (n = natural odd number, l = wavelength of light ). In this example, the refractive index anisotropy Δη of the liquid crystal 16 changes with the applied voltage. In detail, if a voltage is applied between the first type electrode 22a and the second type electrode 22b, the liquid crystal 16 thereof will be tilted in the direction of the electric field, and the refractive index anisotropy Δη of the liquid crystal 16 will increase. Therefore, the value of the delay Ληοΐ also gradually increases from zero. For example, assuming the wavelength of the light being converted; I has the greatest illumination efficiency at 550 nm; then the 1/4 system is about 140 nm. The hysteresis And value of the liquid crystal 16 at a predetermined applied voltage is 140 nm, so the function of the liquid crystal 16 is the same; the 1/4 plate can rotate the polarization direction of light by 90 degrees. On the other hand, if the retardation Δ !! of the liquid crystal 16 is not equal to η λ / 4, the error can be inserted between the glass substrate 12 and the polarizing plate 26 by inserting a delay Δικ! Equal to The difference is corrected by the phase filter. Moreover, if the black and white of the liquid crystal 16 are opposite, a phase filter can be inserted, and the retardation And of the liquid crystal 16 will become zero at a predetermined voltage. The figure is a plan view showing a liquid crystal display device of the 128th frame. The difference between this embodiment and the embodiment of FIG. 124 is that a partitioned reflective layer 94 is provided at a position corresponding to each pixel region, so each pixel region Will be driven by three second stripe electrodes 22b and two first stripe electrodes 22a. Therefore, the liquid crystal 16 can be effectively driven with a lower voltage, and the driving voltage (please read the Note: Please fill in this page again) This paper size is applicable to Chinese National Standard (CNS) A4 specification (210X297 mm) 96 Printed by the Consumers' Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 587191 A7 _ B7 And this liquid crystal 16 is equal to η and / 4 It can reduce the power consumption of the liquid crystal display panel. In addition, the first stripe electrodes 22a and the second stripe electrodes 22b are arranged equidistantly on the adjacent pixel area, and the adjacent pixels The boundary of the region is located at the center of the second stripe electrode 22b. Therefore, if a voltage is simultaneously applied to the first stripe electrode 22a of an adjacent pixel region, the second stripe electrode 22b will be replaced by the pixels on both sides thereof. The area is shared, and the alignment direction of the liquid crystal in the entire pixel area > including the boundary of adjacent pixel areas will be changed, so a high contrast can be obtained.

The metal layer (Ti / Al / Ti) 103 of the electrode is arranged layer by layer. The resistive contact layer 102 is used to improve the resistive contact between the metal layer 103 and the amorphous silicon 100. The metal layer (Ti / Al / Ti) 103 is a multilayer structure including a titanium film with a thickness of about 500A and an aluminum film (underlayer) with a thickness of about 1500A.

In this example, as shown in FIG. 134A, the reflective layer 94 is disposed on the back surface (bottom surface in the figure) of the glass substrate 14, so the second electrode 22b and the gate bus 30 can be disposed at the same time.

In this embodiment, the second strip electrode 22b of the embodiment shown in the 129th stage is provided on the back surface of the glass substrate 12. The second strip electrode 22b is provided on the display side of the reflective layer 94, and therefore a transparent electrode of indium tin oxide (ITO) having a thickness of about 1000 A is used. > In Section 135 (b), the electric field between the first and second type electrodes 22a and 22b forms a direction substantially parallel to the glass substrates 12, 14 (more strictly speaking, there are some parallel oblique Tilt direction), so when a voltage is applied to the liquid crystal 16, the alignment direction is also substantially parallel.

Description of the invention (97)

LA-121) manufactured by Chemical Co., Ltd. and a two-color pigment are added as a liquid crystal. In this embodiment, although the structure is similar to that shown in Fig. 129, a polarizing plate is not provided on the glass substrate 12. Specifically, the polarizing plate is not required because the function of the λ / 4 plate is provided by the insulating layer 50c. The insulating layer 50c is produced by polymerizing a liquid crystal prepolymer. The prepolymer of this liquid crystal can be aligned and can function as a λ / 4 plate with optical anisotropy. The liquid crystal display panel according to this embodiment can achieve high contrast without any polarizing plate. When a voltage is applied between the first and second strip electrodes 22a, 22b, the guest-host liquid crystal 16 is aligned in a horizontal direction and absorbs incident light polarized in a predetermined direction. This incident light is reflected on the reflective layer 94 to form reflected light. When the reflected light passes through the insulating layer 50c of the 1/4 plate, its polarization direction will be rotated by 90 degrees, and it will be absorbed in the guest-host liquid crystal 16 again. As a result, the guest-host liquid crystal 16 can sufficiently absorb light and improve the contrast of the liquid crystal display panel. According to this embodiment, the first strip-type electrode 22a and the second strip-type electrode 22b do not form a mutually opposite relationship. Therefore, the capacitors formed between these electrodes will decrease, and the electrostatic capacitance between these electrodes will also decrease. As a result, the ratio of the electrostatic capacitance to the electrostatic capacitance between the auxiliary electrodes is reduced, so that the charge leakage effect of the pixel region can be reduced. Although the charge leakage of the guest-host liquid crystal will increase in this way, An azo pigment with excellent optical characteristics, such as a better dichroic ratio. The optical characteristics of the guest-host liquid crystal 16 are the size of the paper used in the vertical direction. The Chinese national standard (CNS) A4 specification (210X297 mm) is applicable. ----- (Please read the precautions on the back before filling (This page) 4 Order printed by the Consumers' Cooperative of Xihui Property Bureau of the Ministry of Economic Affairs 100 587191 Α7 Β7 V. Description of the invention (98) The two-color ratio between the light absorbed by the two-color pigments and the light absorbed by the two-color pigments arranged in the horizontal direction is expressed. . Among them, the guest-host liquid crystal 16 having an insoluble two-color pigment having a high two-color ratio can achieve a high reflectance. The two-color material is largely divided into the even II group and the onion brewing group. Although the azo group has a higher two-color ratio, it will increase the charge leakage, while the anthracene group has a lower two-color ratio, but it will reduce the charge leakage. According to this embodiment, it has become possible to use an azo I-based pigment having a high two-color ratio, even though the guest-host liquid crystal has a large charge leakage, as long as the effect of the charge leakage is reduced. Therefore, approximately 20% higher reflectance than the conventional technique can be achieved. It can also be confirmed from experiments that the guest-host liquid crystal 16 added with an azo-based pigment can restore a reduced voltage holding ratio by long-term annealing. Therefore, if the voltage holding ratio is reduced, the liquid crystal display panel can be subjected to long-term operation by repeated annealing treatment. In the embodiment shown by circle 136, the second strip electrode 22b may use an azo-based pigment having excellent optical properties. The guest-host liquid crystal added therein, even if there is a large charge leakage, It is sufficient that a substantially parallel electric field is generated between the second stripe type electrode 22b and the first stripe type electrode 22a.

In this example, the horizontal alignment layers 90 and 92 are rubbed in a direction of approximately 45 degrees with respect to the directions of the first and second strip electrodes 22a and 22b. As a result, when no voltage is applied, The liquid crystal molecules are aligned in the same horizontal direction as the rubbing direction. On the other hand, when a voltage is applied between the first strip-type electrode 22a and the second strip-type electrode 22b, the liquid crystal molecules rotate about 45 degrees in a plane parallel to the glass substrates 12, 14 and thus form The state parallel or perpendicular to the first strip-type electrode 22a and the second strip-type electrode 22b. This state is similar to the corresponding state in the first embodiment, in which the polarization direction of light is rotated by about 90 degrees. Therefore, by setting the absorption axis or the transmission axis of the polarizing plate 26 at a position parallel or perpendicular to the alignment direction where the liquid crystal is not applied with voltage, the light can be switched and controlled.

When a voltage is applied between the first and second strip electrodes 22a, 22b, the liquid crystal molecules will rotate about 90 degrees in a plane parallel to the glass substrates 12, 14 to form approximately parallel or perpendicular to the The state of the electrode direction. In this method, by setting the absorption axis or transmission axis of the polarizing plate 26 to 1, parallel or perpendicular to the alignment direction when the liquid crystal is not applied with voltage, the light can be switched and controlled.

Description of the invention (102) Sections 144 and 145 囷 are the invention Sectional view and plan view of a modified example of the liquid crystal display device of FIG. The structure is substantially similar to the embodiment shown in FIG. 129, in which the second strip electrode 22b and the reflective layer 94 are connected by a contact hole 97. Since the reflective layer 94 is made of a conductive material such as aluminum, the reflective layer 94 and the second strip-type electrode 22 b can be connected by the contact hole 97. In this example, the contact hole 97 is made by irradiating a purple > outside line at a selected time, such as the contact hole 96. Since the reflective layer 94 and the second strip-type electrode 22b are connected to each other with a contact hole 97, the first strip-type electrode 22a passes through the insulating layer 50 to form a large storage capacitor with the second strip-type electrode 22b. This auxiliary capacitor will improve the retention rate of the data voltage applied to the first type electrode 22a, and can display the image with less fluctuation. This auxiliary capacitor can also be provided in the embodiment of FIG. 136, so an azo-based pigment having a high two-color ratio, although having a large charge leakage, can be added to the guest-host liquid crystal 16 as described above. According to the foregoing description of the present invention, it should be understood that the > liquid crystal existing between the pixels can be driven, so the reflectance and contrast of the liquid crystal display panel can be improved. In addition, the first and second strip electrodes are provided on a substrate _, so the electrostatic capacitance of the pixel region will be reduced, so that it can use a liquid crystal material with excellent optical characteristics such as transmittance. In addition, the opposite parallel tubular electrodes are not used, so the manufacturing process can be simplified and a low-cost liquid crystal display panel can be provided. Furthermore, according to the present invention, a reflective liquid crystal display device with low power consumption and high light usage rate can be made. In particular, a common first paper size is provided at the boundary between two adjacent pixels.

Description of the invention (1Q3) The strip electrode can be changed The liquid crystal alignment direction of the entire pixel region including the boundary between adjacent pixel regions, provided that these adjacent pixel regions are driven simultaneously. Therefore, the liquid crystals at the boundary portions of adjacent pixel regions are constantly driven to achieve a high contrast. In addition, an insulating layer is provided between a conductive reflective layer and the second strip electrode, and the reflective layer and the second strip electrode are connected by a contact hole. The reflective layer is provided so that at least a portion on the first type electrode is closer to the liquid crystal. Figures 146 and 147 show a liquid crystal display device similar to Figure 6 and show the alignment state of the liquid crystal in more detail. 148A and 148B show portions of the liquid crystal display device in Figs. 146 and 147 near the surface of the dielectric layer 36. Figs. In the liquid crystal display device in Figs. 146 to 148B, a color filter substrate 12 has a transparent electrode 18 covering the entire surface of the dielectric layer 36, and a TF butyl plate 14 has first and second strip electrodes 22a, 22b. The first type electrode 22a is connected to a TFT 34 and is fed with a data voltage. The second type electrode 22b is connected to a common bus line 40 and is fed with a common voltage. The surface of the dielectric layer 36 is flat and parallel to the substrate surface. In addition, a liquid crystal layer 16 is provided with positive dielectric anisotropy, and vertical alignment layers 20, 24 and polarizing plates 26, 28, and the like. The polarizing plates 26 and 28 are adhered to the outer sides of the substrates 12 and 14 so that their transmission axes are perpendicular to each other. An insulating layer is shown as a whole at 50. When no voltage is applied (Figures 146 and 148A), the liquid crystal molecules are aligned perpendicular to the substrates 12, 14 so that light cannot penetrate the liquid crystal panel. When applying this paper, the Chinese National Standard (CNS) A4 specification (210 × 297 mm) applies (please read the precautions on the back before filling this page). Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives 106 587191 A7 B7 V. Description of the invention (104) When a voltage is applied (Nos. 147 and 148B), the liquid crystal molecules are aligned along the tilt electric field F0 formed between the first stripe electrode 22a and the transparent electrode 18, and the tilt is adjusted. Aligned to the substrates 12, 14, so that light can pass through the liquid crystal panel by the birefringence of the liquid crystal 16. That is, if the surface of the dielectric layer 36 is flat, all liquid crystal molecules are aligned perpendicular to the surface of the dielectric layer 36 when no voltage is applied, as shown in 148A148. When a current is applied, the liquid crystal molecules are aligned along the oblique electric field Fo, and are inclined to the surfaces of the substrates 12, 14. > When the liquid crystal molecules are tilted on the surfaces of the substrates 12 and 14 along the tilting electric field F0, it takes a little time to change from the state of FIG. 148A to 148B due to the alignment regulation force of the alignment layer 20. status. Therefore, the response to drive the liquid crystal is slow, and it is necessary to increase the driving voltage. Figures 149A to 151 show another embodiment of the present invention, which is helpful to solve the problems shown in Figures 146 to 148A. In FIGS. 149A to 151, the surface of the dielectric layer 36 is formed into a curved shape. The alignment layer 20 is also curved, and is the same as the dielectric layer 36. The crossbow shape of the surface of the dielectric layer 36 is set such that a vertical vector at a point on the surface of the dielectric layer 36 will be closer to the vertical vector when the dielectric layer 36 forms a flat surface. A line that is parallel to the line of power passing through that point. That is, the surface of the dielectric layer 36 is inclined in one direction, so that the vertical vector on the surface of the dielectric layer 36 will be close to a power line parallel to F0. Section 149A 囷 shows the alignment state of the liquid crystal molecules when no voltage is applied. When no voltage is applied, the liquid crystal molecules are aligned perpendicular to the surface of the substrate 12.14 and inclined to the surface of the dielectric layer 36. In this way ', by laying obliquely the liquid crystal molecules near the surface of the dielectric layer 36 in advance, when the voltage is applied, the liquid crystal molecules can more easily apply the Chinese national standard (CNS> A4 specification (210X297) on this paper scale) (Mm) --------- ^ .-- (Please read the notes on the back before filling this page) Printed by Xiao Gong Consumer Cooperative, Intellectual Property Bureau, Ministry of Economic Affairs 107 587191 __— 乂 _ ~. ~ .........: ~ ..—. __B7 __% · /.

Preferably, the convex portion 36b includes the width of the slope portion, which is equal to or smaller than that of the second strip electrode 22b. Width, and the width of the recessed portion 36a including the slope portion is also equal to or smaller than the width of the first strip electrode 22a. In this example, the area curved along the surface of the dielectric layer 36 is only in The part on the first and second strip electrodes 22a, 22b. If it is driven by the active substrate, a selected pulse voltage will be applied. Apply to the gate bus line 30, and when When this pulse voltage is not applied, a voltage of negative several volts is usually applied. Therefore, the gate bus 30 and the first and second type electrodes 22a and 22b (or the first and second electrodes in FIG. 50) A large electric field will be generated between the connecting electrodes 22c, 22d), so a problem will occur, that is, because the distance between the gate bus 30 and the first and second strip electrodes 22a, 22b increases, so The aperture ratio will decrease, or a shield electrode is sometimes required. Figure 153 is used to explain the problem of liquid crystal alignment caused by the electric field between the gate bus line 30 and the second electrode F22b. Figure 153 The alignment of the liquid crystal in the RA and RB regions is irregular. Fig. 154 shows an example, and the alignment problem of the winter liquid crystal shown in Fig. 153 can be obtained by bending the surface of the interlayer 36. Prevent the surface of the dielectric layer 36 from being set so that the electric field between the gate bus line 30 and the second electrode 22 b can be adjusted with the alignment regulation of the alignment layer 20 on the dielectric layer 36. The force is flattened so that the liquid crystal molecules near the dielectric layer 36 (in the RC region) are aligned perpendicular to the substrate. In this example The surface of the dielectric layer 36 is curved in the RC region, so it has the relationship of L1> L2.

Description of the invention (107) Question The thickness of the portion of the Yali line 30 is B, and the thickness of the portion of the dielectric layer corresponding to the second type electrode 22b is L2. It is expedient to balance the electric field between the voltage of the inter-electrode bus line 30 and the common voltage with the alignment regulation force, because the second type electrode 22b is applied with a substantially constant common voltage. In addition, regarding the first type electrode 22 &, an AC voltage will be supplied to the first type electrode 22a, and its intermediate voltage is the same as the common voltage, so its electric field will be balanced with the regulation regulatory force, if a substantially A voltage equal to the common voltage is applied to the first strip electrode. As a result, 'the distance between the gate electrode 3 (> and the stripe electrode') and the width of the shield electrode can be reduced to increase the aperture ratio. Fig. 155 is for illustration. If the surface of the dielectric layer 36 is bent, then It will add a lens-like function. The dielectric layer 36 in Figure 155 is a concave lens. Therefore, 'the dielectric layer 36 has the function of a concave lens, and the light directed to the second strip electrode 22b will be concentrated in the first section. The gap portion between the first and second strip electrodes 22a, 22b can increase the actual aperture ratio.-A 15-type XGA liquid crystal display device according to Example 152 圊 is made by the following method.

The insulating layers 50a and 5Ob have openings 50h above the second strip electrode 22b, and the side walls of the openings 50h are pushed obliquely from above. That is, the equal openings 50h are formed by one side of the TFT substrate 14. It extends to one side of the color filter substrate 12. The profiles of the openings 50h are also shown in FIG. 156.

The horizontal electric field is generated between the first and second strip electrodes 22a, 22b, which can assist the alignment of the liquid crystal driven by the inclined electric field f0. The electric field formed near the second strip electrode 22b does not have to be the same as the oblique electric field F0, and the liquid crystal molecules will be biased along the oblique electric paper.

However, the liquid crystal molecules located near the pushing wall 50i of the opening 50h will be aligned perpendicular to the pushing wall 50i. As a result, the alignment state of these liquid crystal molecules will be aligned with the liquid crystal molecules aligned along the inclined electric field F0. Consistent. Therefore, the alignment of the liquid crystal can be improved. Fig. 158 (i) shows a modified example of the opening 50h of the insulating layers 50a and 50b. The openings 50h are provided in the insulating layers 50a and 50b above the second strip electrode 22b, and the openings 50j are provided in the insulating layers 50a and 50b above the first strip electrode 22a. The ends of the openings 50h and 50j are narrower than the first and second strip electrodes 22a and 22b.

The dielectric layer 36 includes the transparent resin layer 36 x. In FIG. 161, the transparent electrode 18 is provided on the surface of the substrate 12, the color layer 38 is provided on the transparent electrode 18, and the alignment layer 20 is provided on the ocher layer 38. The dielectric layer 36 includes the color filter layer 38. The black matrix is substantially provided on the substrate 12. When the dielectric layer 36 is manufactured, if the ratio (d / ε) of the thickness d to the relative dielectric constant e of the dielectric layer 36 is inappropriate, sufficient brightness required for display cannot be obtained. Moreover, if it is a 160th device, wherein the dielectric layer 36 includes a transparent resin layer 36x, after the liquid crystal panel is manufactured, when the liquid crystal panel is used to form an image, image retention of the screen may occur. If it is the device of FIG. 161, where the dielectric layer 36 includes a color filter layer 38 ', the screen image retention will not occur, but only the thin alignment film 20 exists in the liquid crystal layer 16 and the color filter layer 38. Therefore, there is a problem that the voltage holding ratio may be reduced by the contamination of the liquid crystal layer 16 caused by the color filter layer 38. The relative dielectric constant e of the color filter layer 38 is higher than that of the transparent resin. For example, the relative dielectric constant e of the transparent resin is approximately 3 to 3 · 3, and the color filter layer 38 is 3.5 to 4. The voltage applied to the liquid crystal by the transparent electrode 18 is affected by the neodymium dielectric layer 36 because the transparent electrode 18 is disposed under the dielectric layer 36. When the relative dielectric constant? Of the dielectric layer 36 is changed, the thickness of the dielectric layer 36 needs to be relatively changed so that the voltage applied to the liquid crystal layer is kept constant.

V. Description of the invention (111) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs If the relative dielectric constant is a high value, the thickness of the dielectric layer 36 must be increased accordingly. In particular, 'if the dielectric layer 1 has a di-degree and a relative dielectric constant e 1 and the dielectric layer 2 has a d 2 thickness and a relative dielectric constant e 2, it is best to keep the voltage applied to the liquid crystal layer constant. The following 歹 f relationship can be satisfied: (dl / ε 1) = (d2 / e 2) As a result of research on actual use of various resins, it has been found that the display brightness is related to the relative dielectric constant and the thickness of the dielectric layer. Section 162 囷 shows the relationship between the ratio of the thickness to the relative dielectric constant (d / ε 'unit is f // zm) and the transmittance when a voltage of 10V is applied, where ε (unit f) is the relative dielectric constant, d (unit is the thickness of the dielectric layer 36. The ratio (d / ε) is shown on the X-axis and the transmittance is shown on the γ-axis. When the d / ε ratio is close to 0.7 f / # m, its brightness (Transmittance) is the southernmost β. When the d / ε ratio exceeds 0.7 f / m, the brightness will decrease slightly. When the d / ε ratio is lower than 0 · 7 f /// m, the brightness will vary with d. / e value decreases. From the result of 162 第, the d / e value is preferably equal to or greater than 0f / βm. In the range of d / ε value higher than 0.7f // zm, the medium The transmittance and brightness of the electrical layer 36 itself will decrease. Therefore, it is also important that the d / e is not too high, and it is preferable that the d / ε value be lower than o.Qf / em. The dielectric layer 3 The burning of 6 is also related to its resistivity. There is a trend that the lower the resistivity of the dielectric layer 36, the lower the degree of screen image retention. As the thickness of the dielectric layer 36 increases, the resistivity will increase. Becomes taller and the screen image retention process changes In the structure of the dielectric layer 36 containing the transparent resin layer 36x, the dielectric layer 36 needs to have a certain thickness to meet the required brightness, so its resistivity is based on the Chinese National Standard (CNS) A4 specification (210 X 297 Public Love 7 III Γ II Surface III — I · IIIIIII — — — — — — — I® (Please read the notes on the back before filling out this page) 114 587191 A7 B7 V.

Conversely, in the structure of the dielectric layer 36 containing the color filter 38, when the color filter 38 has a conventional thickness At this time, it cannot be said that sufficient brightness can be obtained. However, the resistivity is not too high, and screen image retention does not occur. Therefore, in the structure of the dielectric layer 36 including the color filter 38 and the transparent resin layer 36x, As shown in Section 159 (b), the aforementioned problems can be solved at the same time. Under this condition, the transparent resin layer 36x is preferably thinner than the color filter 38. The thickness of the dielectric layer 36 in this example is more than Single layer color filter The dielectric layer 36 of 38 is thicker to form a thickness capable of ensuring sufficient brightness. In addition, in this example, the resistivity of the dielectric layer 36 is smaller than that of the dielectric layer 36 ′ containing a single transparent resin layer 3 ′. No screen image retention will occur. In addition, the liquid crystal layer 16 will not be contaminated by the color filter layer 38 because the transparent resin layer 36x having a higher concentration than the color filter 38 is provided outside the color filter 38 Therefore, it is possible to solve the problem of reduced voltage holding ability. In the dielectric layer 36 including the color filter 38 and the transparent resin layer 36x, it is desirable to satisfy 0 · 5 < (ο! 1 / ε 1) + ( The relationship of (12 / ε 2) is similar to the single-layer dielectric layer 36. More preferably, it can satisfy the relationship of 0.5 < ((11 / ε 丨) + ((12 / ε 2) < 9). Figure 163 shows the thickness of the transparent resin layer 36χ of the dielectric layer 36 and the screen image. The relationship between the stagnation, where the thickness of the color filter 38 is 2 ν m. The image stagnation of the screen is expressed as the sum of the squares (ST) of the difference between the brightness before the voltage is applied and the brightness after the 3 V voltage is applied It will be seen that the larger the thickness of the transparent resin layer 36x, the greater the degree of screen image retention.

Description of the invention (113) The larger the ratio becomes, the more The role of the low-resistance color filter 38 under the transparent resin layer 36x becomes low, so that the charge is easily accumulated. That is, if the low-resistance color filter 38 in the transparent resin layer 36x is used as a medium, The ratio of the color filters 38 and the like of the electric layer 36 is not very large, so that the work of preventing the screen image from staying It is not very large.
