Abstract

An electric field controlling electrode overlaying an edge of a source line is provided on a counter substrate to generate a vertical electric field in a gap region between the source line and a common electrode. Thereby, liquid crystal molecules are raised and the gap region is turned to be a black state, which eliminates a light leakage problem and thereby improves a contrast. The use of electric field for preventing the light leakage allows the device to have an increased margin for misalignment of a light blocking region. It is therefore made unnecessary to extend the light blocking region to a pixel region. An aperture ratio is thereby increased.

Description of the invention (2) If printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, it is structured, because an electric field parallel to the substrate can drive the liquid crystal, so that liquid crystal molecules will not stand up from the substrate surface during display, and can see the field of vision. JP-A-9-269504 discloses a structure in which a black matrix of an opposing substrate is formed of a conductive material in the lps mode, and this structure is connected to a common electrode. FIG. 28 shows the structure. The black matrix formed around the color filter Η] is provided with a conductive material. The conductive material 153, such as a conductive adhesive, is short-circuited with the common electrode 154 of the opposite substrate. The housing is obtained by using vertical electricity% The effect of increasing the degree is also described. It also has the effects of preventing afterimages from falling out and shielding the external electric field to suppress the decline in display quality. However, the following problems remain as in the above-mentioned liquid crystal display device. (1) The potential corresponding to the source wiring The display data of other parts changed, resulting in an unwanted electric field between the source wiring and the pixel electrode (or common electrode) on the outermost side of the address pixel. The leakage of light in the gaps causes the contrast to drop or the display to be distorted. (2) When rubbing the liquid crystal for orientation, the gap between the source wiring and the pixel electrode (or common electrode) on the outermost side of the pixel and the gap between the pixels are relatively rough. 'Insufficient orientation of the liquid crystal will cause a decrease in contrast. (3) In order to hide the light-shielding layer (black matrix) on the opposite substrate in order to hide the problematic gaps (1) and (2) above, it is necessary to consider bonding the array substrate The position of the light-shielding layer and the source wiring or the pixel electrode (or the common electrode) is staggered when facing the opposite substrate, so that the marginal light-shielding portion needs to be enlarged, which invites a decrease in the opening efficiency.

Description of the invention (using thin film transistors (TFT: Thln-FUm • Dingchuan). Dynamic matrix LCDs are thin, lightweight, and can be driven at low voltage. These advantages have been used in various fields such as Ding V 'or monitors for camera recorders, personal computers, and personal word processor displays, forming a large market. Especially in recent years, with the increasing use of computers or TVs, The demand for liquid crystal display panels with wider viewing angles is increasing. For the purpose of expanding the viewing angle of liquid crystal display panels, proposals such as Japanese Unexamined Patent Publication No. 160878 have formed pixel electrodes and opposing electrodes on the same substrate. The electric field is a transverse electric field method that causes liquid crystal molecules to move. This method is called IPS (In-Plane-Switching) mode or comb electrode method, and in this display mode, the long axis of the liquid crystal molecules and the substrate are always slightly parallel and not vertical. Therefore, when the viewing angle direction is changed, the brightness change is small to obtain a wide viewing angle. In the liquid crystal display panel, since an unnecessary electric field generated from the source wiring affects the electric field area that controls the display of the liquid crystal, there is a problem that the electric field changes and the display is poor due to the brightness tilt or intermodulation distortion. The 1N5242〇 proposal includes a liquid crystal display device in which a conductive light-shielding film is formed on the opposite side of the source wiring to suppress the influence of the electric field generated from the source wiring on the display, and the left and right brightness differences and intermodulation distortion of the liquid crystal display panel are eliminated. That is, the conventional liquid crystal display device is illustrated by using a diagram.

As shown in the picture of the printed dagger printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the electric field generated from the source wiring 52b can prevent the electric field variation of 4 μm. Therefore, a conductive layer is formed at the position where the opposite wiring b! Light-shielding film (BM ·· black short array) 58. According to the above configuration, an electric field P1 in the vertical direction is generated between the conductive light-shielding film 58 and the source electrode 52 to suppress an unnecessary electric field in the horizontal direction and suppress the influence on the display. And because the potential of the source wiring 52a fluctuates, the potential of the conductive light shielding film 58 above it also changes, so a reverse polarity signal is given to the adjacent source wiring 52b to eliminate the potential variation of the conductive light shielding film and promote conductivity The potential of the light-shielding film 58 is stabilized to obtain the above-mentioned effect.

fruit. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs < 4 Known liquid crystal display device is a stable conductive light-shielding potential, although a reverse polarity signal is applied to the adjacent source wiring, but the source voltage is added to the [Number voltage as shown in the figure] The image often changes, so although the polarity is changed in turn, the signal voltage value varies with each source wiring, which can fully eliminate the potential variation of the light-shielding film. For example, when the g-line pattern is promoted for each g-line along the source wiring direction, although each source wiring is blown to reverse the polarity of the signal voltage, it is applied to the source distribution and the spring in the positive display and the negative display. The voltage values of the children are very different, and the conductive light-shielding film is affected by the potential change in one direction ', so that the potential change cannot be eliminated. Therefore, the electric field of the source wiring cannot be terminated by the conductive light-shielding film. In addition, according to the simulation tests and experiments by the inventors, it was found that when a conductive light-shielding film was formed only for the BM used as a color filter substrate, and a signal voltage of polarity inversion was applied to each source wiring with the same amplitude, it was found that many were insufficient. Suppression of intermodulation distortion. That is, by changing the electrode I degree, the electrode interval, the thickness between the substrates, and the amplitude of the source signal by changing the parameters of the constituent elements of the liquid crystal element, unwanted electric fields leaking from the source wiring cannot be suppressed, and intermodulation distortion will still occur. An example of this result is shown in FIG. 31.

Next, the second invention group will be described. Regarding the second invention group, it is the result of repeated intensive review by the present inventor that the influence of the electric field from the source wiring on the electric field of the display section and the electrode width, electrode interval, and substrate-to-body parameters which are the constituent elements of the liquid component are found. There is a joint relationship between the distance and the amplitude of the source signal. Specifically, it is found that the following ① ~ ④ are related. ① Since the unnecessary electric field strength generated from the source wiring is increased in proportion to the source signal amplitude king, the common electrode shielding the electric field needs to widen its electrode width in proportion to the source signal amplitude strength. In general, although the strength of the electrical boundary occurring from the source wiring is proportional to the amplitude value of the source signal, it is found that there is a proportional relationship between ln (the meaning of L0g with a constant natural logarithm) and the common electrode that shields the electric field. ② In addition, the electric field strength is inversely proportional to the distance. When the distance between the pixel electrode driving the liquid crystal and the electrode of the shared private electrode is widened, the width of the common electrode can be narrowed because it is less susceptible to the influence of the electric field from the source wiring. ③ If the distance between the substrates is small, the width of the common electrode can be reduced because it is less likely to be affected by the electric field from the source wiring. ④ For the electric field shielding electrode arranged on the source wiring, if the width of the electric field shielding electrode is narrower than that of the source wiring, the effect of fully shielding the electric field from the source wiring cannot be obtained.

Description of the invention (20) Printed by the Consumer Consumption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Source wiring 4 and gate wiring 12 have The bifurcated portion, together with the semiconductor layer 15 and the end of the electrode 5 constitutes a thin pseudotransistor 14. However, a thin-film transistor can also be formed on the gate wiring as in the conventional example (Figure 14). 6 is an edge film It has the function of the gate insulating film of the thin film transistor 14. At the same time, it can source the wiring 4. The pixel electrode 5 and the gate wiring 12. The common wiring 3 is isolated 7 is the electric field control electrode, and is formed in the opposite direction to the source wiring 4 Substrate 2. In this embodiment, the electric field control electrode 7 is formed by a transparent π force, such as 1 to 〇. As shown in this embodiment, the electric field control electrode 7 is provided in the opposite substrate 2 to the source wiring 4 On the side, the electric field generated between the source wiring 4 and the electric field control electrode 7 can promote the source wiring 4 The nearby liquid crystal molecules are vertically oriented to prevent light leakage from the source wiring 4 and the common electrode 3 to enhance the contrast. The principle, function, and effect of the electric field control electrode 7 will be described in detail later. 8 for color display The required color filter. Although not shown, the innermost surface of each plate 1, 2 is formed with an orientation film to regulate the orientation direction of the liquid crystal molecules on the plane of the liquid crystal layer. The orientation direction of the liquid crystal is parallel to the pixel The direction of electrode extension or a direction inclined by several degrees. ⑺ and 丨 丨 are polarizing plates, and the polarization axes of the two are slightly orthogonal to each other, and any one of them is arranged to be slightly parallel to the orientation direction of the liquid crystal. The operation of the liquid crystal display device. When the selection voltage (approximately 15 to 20 volts) is applied to the gate wiring 12, the thin film transistor μ is ON. At this time, the source wiring 4 is supplied with a positive signal voltage corresponding to the display ^ ~ 7 volts). This signal voltage charges the pixel electrode 5. The potential of the common electrode ^ is formed to zero volts through the common common wiring 13.

State while maintaining the pixel potential. I ... Presented 0FF. The second frame is to supply the signal voltage of the source wiring 4 (page power (~ 0 volts)). The above 4 charges the liquid layer 9 with a negative signal voltage. As a result, the liquid crystal is driven by AC. The contrast enhancement effect of the liquid crystal display device of this embodiment will be described below. When Shitian applies the same potential (zero volt potential) to the common electrode 3 to the t 昜 control package electrode 7, the electric field distribution in the cross section of the liquid crystal display device is as shown in FIG. 2. That is, for the central part of the pixel related to the display, the horizontal electric field E1 is used as the control subject, and there is no direct relationship between the display and the source. The periphery of the 4 source wiring is controlled by the t-field E2 in the slightly vertical direction, which can make the structure known The undesired horizontal electric field component E3 is greatly reduced. As a result, the liquid crystal molecules in the gap portion 16 between the source wiring and the common wiring rise from the substrate surface. And because the polarizing axes of the light-preparing plates 10 and U are orthogonal, the display of the part becomes black, and the light leakage caused by the electric field of the passive wiring 4 can perform high-contrast display. In the conventional liquid crystal display device, the gap portion 16 is narrower than the gap between the common electrode 3 and the pixel electrode 5 in the display portion, which causes the liquid crystal to fail to damage the orientation. Therefore, light leakage / clearing occurs. In the liquid crystal display device of this embodiment, a vertical electric field is applied to the gap portion 16, so that the gap portion 16 can have a black matrix state regardless of the orientation. As a result, it is possible to perform display with high contrast without light leakage. As mentioned above, both the display pixel electrode 3 and the source wiring are -------- ^ --------- (Please fill in this page with the precautions on the back first) This paper size applies to China National Standard (CNS) A4 Specification (210 297 mm) 24 525008 A7 B7 < 1 Printed by the Consumers' Cooperative of the Ministry of Economic Affairs Intellectual Property Bureau V. Invention Description (22) is positive potential. Another advantage of this R-example liquid crystal display device is that it hardly causes a decrease in the opening efficiency to obtain the above-mentioned improvement effect of the ratio. This is explained below. First, a conventional liquid crystal display device will be described, and a technique for improving the contrast is to use a black matrix BM to shield the gap portion from light. Fig. 3 is a cross-sectional view illustrating the influence of the black matrix of the conventional example. In FIG. 3, 201 and 202 are substrates, 203 is a common electrode, 204 is a source wiring, 205 is a pixel electrode, 206 is an insulating layer, 209 is a liquid crystal layer, and 21 and 211 are polarizing plates. A color filter 208 and a BM217 are formed on the substrate 202. This BM is used to conceal light leakage from a gap between the source wiring 204 and its adjacent common electrode 203. However, the wide W B Μ is set to be D1 on both sides of the male than the distance between the edges of the common electrode display area adjacent to the source wiring due to staggered margins when the upper and lower substrates are attached. It is known that the liquid crystal display device cannot use the light of the part D !, but the opening efficiency decreases, and the display becomes darker. Instead of the black matrix, the liquid crystal display device of this embodiment uses an electric field control electrode made of a transparent envelope to shield the light source wiring and the gap between the adjacent common electrode. According to this structure, the opening efficiency can be improved for the following two reasons. In order to obtain a vertical electric field, the first electric field control electrode does not need to cover the entire width L2 of the gap. Therefore, the width W of the electric field control electrode can be set to be narrower than the width WBM of the BM of FIG. 3. Although the second ’electric field control electrode is exposed outside the picture due to its position shift, etc., it is also not transparent because it is a transparent electrode.

Description of the Invention (23) The printing of employee cooperatives in the Intellectual Property Bureau of the Ministry of Economic Affairs is only slightly reduced. When the width W of the electric field control electrode is too wide, a vertical horizontal electric field occurs in the pixel area, which is not sufficient with the liquid crystal. When it is too narrow, the area in which the vertical electric field can be obtained becomes smaller, and the electric field control effect is insufficient. . According to the experimental results of the present inventors, better results can be given in the range of L2-WC0M ^ L1 ⑴, more preferably in the range of L2S W $ L1 (2). In addition, if the electric field control electrode and the black matrix are used in combination, the shading effect can be improved and the display with a higher contrast can be ordered. At this time, it is not necessary to set the BM IteWBM to be larger than L1 as in the conventional example. The liquid crystal display device of this κ% example can be produced, for example, as follows. Baixian formed a first conductive film layer made of A1 alloy and the like on the first substrate and made a wiring pattern by spraying method to obtain the gate wiring I], ′, $ pole 3, and wiring 13. Secondly, after the insulating film is formed, a semiconductor layer ι5 formed by a-si etc. is formed by the c: VD method. Then, a second conductive film layer made of an a1 alloy or the like is formed by a spray method or the like and a wiring pattern is formed to obtain a source wiring 4 and a pixel electrode 5. After that, another insulating film may be formed to protect the switching element or the electrode. Further, a "color filter layer 8 in which RGB three colors are arranged in a dot shape" is formed on the second substrate 2 and, for example, an electric field control electrode 7 is formed using a transparent electrode material such as IT0. The two substrates thus made are coated with an orientation film to perform a predetermined direction.

After rubbing, the surrounding part was sealed with a sealant, and then the liquid crystal 9 was injected and sealed to obtain a liquid crystal panel printed by the Consumer Cooperative of the M-Jibu Intellectual Property Bureau. Then, an automatic circuit is connected around the liquid crystal panel to obtain a amorphous display device. According to the liquid crystal display device of this embodiment, the liquid crystal molecules in the gap portion between the source wiring and the common wiring can be caused to rise from the substrate surface due to the electric field control electrode. Hai injury. Back into a black state. Therefore, it is possible to eliminate light leakage caused by the electric field of the source wiring or light gap caused by insufficient orientation of the gap portion, so as to perform high-contrast display. In addition, in order to prevent light leakage, it is not necessary to block the light by a black matrix even in the display area, so the opening efficiency can be improved and a bright display can be performed. Although this example illustrates that the common wiring is adjacent to the source wiring, the pixel pen is connected to the source wiring and the electric field control electrode is formed at the edge of the source wiring. The same principle can be used to achieve high contrast and high opening efficiency. display. Although the electric field control electrode 7 is formed on the side of the color filter 8 near the liquid crystal layer 'in the above description, the order may be reversed. That is, the electric field control electrode 7 is formed on the inner side surface of the alignment substrate 2 first, and then the electric field control private electrode is formed to cover the electric field control private electrode to form a color filter 8. In this configuration, although the voltage loss may occur due to the color filter, However, since it is not necessary to form an electrode on the color filter, it has the advantage of being easy to manufacture. (Embodiment 1-2) This embodiment is formed by forming the electric field control electrode of the liquid crystal display device described in Embodiment 1-1 with a light-shielding metal. If the electric field control electrode 7 shown in Figs. 1 and 2 is formed of a metal film such as chromium instead of the transparent electrode, the contrast can be improved due to the light shielding effect on the electrode.

The parts with the same symbols in FIG. 1 are those who perform the same operations as those of the actual gun example M, and therefore the description is omitted. "The liquid crystal display device of this embodiment is provided with the electric field control electrode 7 so as to cover both the edge portion of the source wiring 4 and the edge portion of the gate wiring 12. Since the electric field formed by the vertical component is mainly described in Example 1-1, It also occurs around the gate wiring, so it can suppress light leakage from the periphery of the gate wiring to improve the contrast. The electric field control electrode can be formed by either a transparent electrode or a metal. The width of the electric field control electrode on the gate wiring side is wide. When the distance between the edge of the pixel electrode of the wiring between the support or the edge of the common electrode is L2, L2-WC0 "W (8) is better, and ^ (9) is satisfied, and good display characteristics can be obtained. The potential imparted to the electric field control electrode may be set to the same potential as the common electrode as in the embodiment, or it may be set to a potential with the opposite polarity to the source wiring as in the embodiment. As shown in Figure 4, the potential of the gate wiring is -10 volts in almost all periods. Therefore, applying a bias of about 1 volt to the positive side in any case can promote the electric field between the gate wiring and the electric field control electrode to become stronger. , And improve the shading effect of the gate wiring side. In the column inversion driving in FIG. 7 or the point inversion driving in FIG. 8, the potentials of the source distributions have opposite polarities in each column. At this time, in order to make the potential of the electric field control electrode opposite to the source wiring, it is necessary to isolate the electric field control electrodes of each column. If the liquid crystal display device of this embodiment is to be used for this kind of driving, the gate wiring can be used to isolate between the columns as shown in FIG.

This structure is effective when there is no light leakage on the source wiring side. The liquid crystal display device of Example 'has no gap between the source wiring 4 and the adjacent common electrode 3. Therefore, there is no light leakage from the source wiring side, and the electric field control electrode 7 can be formed only on the gate wiring side. As before. As explained, the gate wiring is applied with a non-selective voltage of about 10 volts almost all the time. The control electrode is more suitable to make volts or a little positive voltage. Also, although the common electrode 3 is formed on the lower layer than the source wiring 4 in the figure, the third electrode layer is formed on the common electrode 3, for example. If the layer is higher than the source wiring 4, the electric field from the source wiring can be shielded, so that the light leakage on the line side can be reduced.

The difference from the embodiment M (Fig. 1) is that the liquid crystal display device of this embodiment replaces the electric field control electrode 7, and a vertical alignment area 21 is provided around the source wiring 4 and the gate wiring port. In this way, the gap between the source wiring and the common wiring, or the peripheral portion of the gate wiring, or the day and night knife, is the state where the king stands up from the substrate surface. Since the polarized light of the polarizing plates 10 and 11 is more orthogonally arranged, the display in this part becomes a black background state, and a high contrast display can be performed. The liquid crystal display device of this embodiment 1-b can be manufactured, for example, as follows.

On the second substrate 2, a color filter layer 8 in which three RGB colors are arranged in a dot shape is formed. The two substrates thus produced were coated with a first alignment film and polished in a predetermined direction.

On the second substrate 2, a black to black layer 8 is formed. The coffee is arranged in a dot pattern. The two substrates thus produced are coated with an orientation film and polished in a predetermined direction. Then, the peripheral portion was adhered with a sealant to obtain a panel (hollow panel) without liquid crystal injection. The hollow panel is formed with an electric field control current r, a, as shown in a plan view of FIG. 9, for example. A liquid crystal containing a hardening polymer at a weight ratio of 0.1% πν is injected and sealed in the hollow panel. Then, the gate wiring 12 and the source wiring [the common wiring 13 are all set to the ground state, and an electric voltage of 电极 volts to several tens volts is applied to the electric field control electrode and the panel is irradiated with νv light to promote polymer hardening. Since the AC voltage is applied to the liquid crystal molecules under the field control electrode 7 in an upright state and is fixed by the UV-cured polymer, a vertical alignment field can be formed only under the electric field control electrode 7. Electric field control electrode? When it is transparent, the electric field control electrode 7 side is used, otherwise, the thin film transistor substrate side is provided with a UV irradiation device. The periphery of the liquid crystal panel thus obtained is then connected to drive a circuit to form a liquid crystal display device.

And there is no case where the vertical alignment area extends into the display area due to the misalignment when forming the vertical alignment film, and the opening efficiency is reduced. Also, if a mask covering each pixel's display area is used during UV light irradiation, the polymer in the display portion will not harden, and better and better display characteristics can be obtained.
