Description

  The present invention relates to a liquid crystal display element.

  FIG. 5 is a conceptual diagram based on a micrograph showing a malfunction of liquid crystal between lead lines of a segment electrode pattern substrate of a conventional liquid crystal display element. In this figure, the orientation direction of the liquid crystal in the central portion of the liquid crystal layer is the vertical direction.

  As shown in the figure, the liquid crystal between each of the plurality of drawing lines on the segment electrode pattern substrate may malfunction and the area may appear to be displayed. The area between the two lead lines appears to be displayed when, for example, different voltages of ON / OFF are applied to each of the two lead lines.

  Even if the ON / OFF state is different in DUTY drive, the voltage difference is very small. For example, the voltage difference is approximately 2V or less. Note that the distance between the lead wires used here is 30 μm or more. The reason why the lateral electric field malfunctions with such a wide line-to-line distance and a slight voltage difference is considered to be that the liquid crystal alignment state of the liquid crystal layer is inclined with respect to the electric field direction.

  To support this, the portion where the liquid crystal alignment direction at the center of the liquid crystal layer and the direction of the transverse electric field generated between the lead lines are shifted by about 45 ° (in FIG. 5, three lead lines 2W surrounded by a one-dot chain line are divided into three. Malfunctions tend to be noticeable at the folded central part, and the liquid crystal in the central part of the liquid crystal layer is aligned parallel to or perpendicular to the transverse electric field direction (in FIG. 5, there are three lead lines 2W surrounded by a two-dot chain line). There is a tendency to be inconspicuous in the bottom part of the fold.

  That is, the malfunction is most noticeable when the liquid crystal alignment state in the vicinity of the cell center of the liquid crystal layer is shifted by 45 ° with respect to the horizontal electric field direction, and the least noticeable when the liquid crystal layer is parallel or orthogonal to the horizontal electric field direction. .

  Conventionally, it has been known that when the alignment state of liquid crystal molecules in the vicinity of the center of the cell with respect to the electric field direction is inclined in advance in the plane direction, an electro-optical characteristic having no threshold is exhibited. In addition, it is known that the behavior of liquid crystals responds not by electric field strength but by voltage difference. However, this is an ideal case. Actually, when the distance between the electrodes is about 100 μm or more, the response does not occur with a slight voltage difference. The malfunction as described with reference to FIG. 5 is considered to have occurred because the above conditions are met.

  Here, since the malfunctioning portion is very thin, it is usually not observed unless a microscope is held, and does not cause a problem. However, as shown in FIG. 5, when the lead lines are dense and there are some malfunctioning parts, or when the background is negative and the backlight is bright, there is a tendency that the lines become conspicuous.

  As a measure for eliminating the above-described malfunction, it is conceivable to increase the distance between the drawing lines. When the distance is approximately 100 μm or more, malfunction does not occur. However, due to the wiring design, there is a case where it is inevitably necessary to carry out dense wiring, and such a measure cannot always be taken. In the case where the liquid crystal is 90 ° twisted and the rubbing direction is selected from 45 °, 135 °, 225 °, and 315 °, the wiring direction of the portion where the wiring is dense is 45 ° with respect to the rubbing direction. If the angle is set, the display due to the malfunction becomes inconspicuous, but it is very difficult to make sure that the direction is aligned in design.

  Furthermore, as a countermeasure for eliminating the above-described malfunction, it has been proposed to provide a light shielding film or the like on the lead line of the segment electrode (see Patent Documents 1 and 2). However, the provision of a light shielding film or the like has a problem in that the manufacturing cost increases. In addition, providing a light-shielding film can cope only with a malfunction in a normally black (normally off) liquid crystal display device.

  An object of the present invention is to suppress a malfunction of a liquid crystal display between lead lines of a liquid crystal display element while suppressing an increase in cost.

According to an aspect of the present invention, a liquid crystal display element includes a first glass substrate on which a segment electrode pattern and a lead line pattern are formed, a counter electrode disposed on the first glass substrate, a common electrode pattern, A second glass substrate having a dummy pattern formed in a region facing between the lead line patterns, the gap between the lead line patterns formed on the first glass substrate being 100 μm or less ; A film structure including an alignment film formed to cover a pattern formed on the second glass substrate; and a liquid crystal layer sandwiched between the first and second glass substrates. The first and second glass substrates are overlapped, and the portion where the lead line pattern and the dummy pattern overlap in plan view is 20 μm or less and faces the lead line pattern of the second glass substrate. In the region, the film configuration is directly formed at a position on the substrate other than the position where the dummy pattern is formed.

  ADVANTAGE OF THE INVENTION According to this invention, the malfunctioning of the liquid crystal display between the drawing lines of a liquid crystal display element can be suppressed, suppressing an increase in cost.

  FIG. 1 is a cross-sectional view of a liquid crystal display element 101 using a segment electrode pattern substrate and a common electrode pattern substrate according to a first embodiment of the present invention.

  The patterned segment electrode pattern substrate with ITO 1A and the common electrode pattern substrate 1B (hereinafter, both substrates are simply referred to as a glass substrate 1) are washed, and an insulating film (organic oxide) is formed on the glass substrate 1 by flexographic printing. (Silicon film) 4 is formed to a thickness of 500 to 2000 mm. The insulating film 4 is not essential, but is desirably formed to prevent a short circuit between the upper and lower substrates. In addition to flexographic printing, an insulating film may be formed by a method such as vapor deposition or sputtering using a metal mask.

  A horizontal alignment film 5 having the same pattern as that of the insulating film 4 is formed on the insulating film 4 by flexographic printing or the like. In the case of TN-LCD, it is preferable that the pretilt angle is low (2 ° or less with respect to the substrate plane). For example, the horizontal alignment film 5h is formed with SE-410, which is available from Nissan Chemical, with a thickness of 500 to 800 mm and subjected to rubbing treatment. Rubbing is a process in which a cylindrical roll wound with a cloth is rotated at high speed and rubbed on the horizontal alignment film 5h. The rubbing process direction is set so that the twist angle of the liquid crystal 3x between the upper and lower substrates is 90 ° (left twist).

  A seal material 6 is screen-printed in a predetermined pattern on the segment electrode pattern substrate 1A. A dispenser may be used to form the sealing material 6 instead of screen printing. For the sealing material, for example, thermosetting ES-7500 available from Mitsui Chemicals is used. It may be a photo-curing material or a light / heat combination type sealing material. The sealing material 6 includes 2 wt% of glass fiber having a diameter of 6 μm and 1 wt% of styrene balls subjected to Au plating having a diameter of 6.5 μm.

  A gap control material is sprayed on the common electrode pattern substrate 1B by a dry spraying method. A 6 μm plastic ball is used as the gap control material. A true sphere made of silica may be used.

  The two substrates 1A and 1B are overlapped at predetermined positions so that the horizontal alignment film 5h is on the inside to form a cell, and heat treatment is performed in a pressed state to cure the sealing material 6. In addition, when using a photocurable sealing material, light processing is performed and the sealing material 6 is hardened.

  A glass substrate is scratched with a scriber device, and is divided into a predetermined size and shape by breaking to create empty cells.

  Liquid crystal 3x is vacuum injected into the empty cell. Here, for example, nematic liquid crystal (mixture: Δn = 0.082) manufactured by Dainippon Ink and Chemicals, Inc. having a positive Δε is used. Thereafter, the inlet is sealed with an end seal material. Thereafter, the glass substrate is chamfered and cleaned to form a liquid crystal cell 101c. A polarizing plate 8 is attached to the liquid crystal cell 101c in a crossed Nicol arrangement to complete a TN mode normally white (normally on) type liquid crystal display element 101.

  FIG. 2 is a schematic cross-sectional view of the liquid crystal display element 101 for explaining the configuration and manufacturing method of the segment electrode pattern substrate and the common electrode pattern substrate according to the first embodiment of the present invention.

  First, the segment electrode pattern substrate 1A is manufactured by a known method. On the other hand, when the common electrode pattern substrate 1B is manufactured, the inter-electrode distance of the lead wire 2W in the segment electrode pattern 2 formed on the electrode surface of the segment electrode pattern substrate 1A is 100 μm or less (in practice, the line A region having a width of 100 μm and a line-to-line distance of 30 μm, and an angle Φ formed by the rubbing direction and the drawing line direction is −30 ° <Φ <30 ° or 60 ° <Φ <120 ° (that is, a liquid crystal layer) In the vicinity of the center, the liquid crystal alignment state is a region that is displaced by 45 ° or 135 ° (about ± 30 °) with respect to the horizontal electric field direction caused by the voltage difference between two adjacent lead lines, and is rubbed In the direction excluding the direction where the angle Φ between the direction and the lead line direction is around 45 °), the portion corresponding to the electrode of the lead line 2W on the common electrode pattern substrate 1B facing each other A dummy transparent electrode film 2D (hereinafter, simply referred to as dummy electrode pattern 2D) to form an island shape. That is, as described above, the distance between the electrodes is 100 μm or less, and the liquid crystal alignment state in the vicinity of the cell center of the liquid crystal layer 101q is shifted by 45 ° with respect to the horizontal electric field direction due to the voltage difference between two adjacent lead lines. Since the malfunction tends to be most noticeable, the dummy electrode pattern 2D is formed in the region.

  Since the pattern of the dummy electrode pattern 2D can be formed at the same time when the common electrode pattern is created by adding the pattern when designing the photomask pattern of the common electrode pattern, no additional process is required. Note that the dummy electrode pattern 2D is preferably not overlapped with the pattern of the lead wire 2W when the segment electrode pattern substrate 1A and the common electrode pattern substrate 1B are overlapped and viewed from above the substrate plane. In consideration of the above, it is desirable that the wiring line is formed so as to be separated from the pattern of the drawing line 2W by about 5 to 20 μm. In addition, even if they overlap, if the amount of overlap is set to 0 to 20 μm, even if a malfunction occurs, lighting due to the response in this size range is very observable visually, and malfunction due to static electricity It is considered that there is no practical problem because is temporary.

  Hereinafter, an example of a method for producing the segment electrode pattern substrate 1A and the common electrode pattern substrate 1B will be described.

First, an indium tin oxide (ITO) film, which is a transparent electrode film, is formed on the surface of a glass substrate using alkali-free glass (white plate glass) or soda lime glass (blue plate glass) by CVD, vapor deposition, sputtering, etc. The ITO film is patterned into a predetermined pattern using photolithography. For patterning, a photoresist material is first formed on the ITO film with a thickness of several microns using a roll coater or a slit coater. Here, a positive resist (OFPR-800) manufactured by Tokyo Ohka Co., Ltd. is formed with a thickness of 1.5 μm using a roll coater. Next, a pre-bake process is performed at 110 ° C. for 3 minutes on a hot plate, and ultraviolet rays are irradiated at 100 mJ / cm ² through a mask having a predetermined pattern using an exposure machine. Thereafter, development is performed using an alkaline solution (1 wt% KOH), and post-baking is performed at 130 ° C. for 3 minutes on a hot plate. Further, wet etching is then performed using an etchant for ITO (Nitrogen / chlorine-based, ferric chloride-based (FeCl ₃ ), etc. such as ITO series (ITO-02, ITO-06N, ITO-07N) manufactured by Kanto Kagaku). Finally, the resist material is removed using a strong alkaline solution (3 wt% NaOH). Although a general exposure machine is used here, a maskless exposure method using a laser may be used.

  When the liquid crystal display element according to the first embodiment of the present invention manufactured as described above is driven by applying a 5V AC voltage by static drive and visually observed, the malfunction due to the lead line observed in FIG. It was not confirmed.

  The reason for eliminating the malfunction will be considered below.

  As shown in FIG. 3, in the state where there is no dummy pattern between the lead lines 2W, when a potential difference occurs between the lead lines 2W, the electric field crosses the liquid crystal layer 101q in the horizontal direction as shown by arrows in the figure. It takes. When a voltage is applied in the horizontal direction with respect to the liquid crystal alignment of TN, the liquid crystal molecules operate sensitively, and even a slight voltage difference is inclined in the direction of the electric field, causing malfunction.

  In the first embodiment of the present invention, as shown in FIG. 2, even if a potential difference occurs between the routing lines 2W, each routing line 2W and the counter substrate (common electrode pattern substrate) are more than the distance between the routing lines 2W. ) The distance from the dummy pattern 2D formed on 1A is shorter (distance between the lead lines 2W: 30 to 100 μm, distance between the lead lines 2W and the dummy pattern 2D: 6 to 30 μm). Accordingly, since the ITO resistance is overwhelmingly lower than the resistance of the liquid crystal, the direction of the electric field is applied between the lead-out line 2W and the dummy pattern 2D, that is, substantially in the cell thickness direction, as indicated by an arrow in the figure. Since the liquid crystal molecules in the cell thickness direction are arranged in a state of being substantially lying with respect to the electric field direction (not substantially inclined with respect to the electric field direction), even if a voltage of a threshold value (2.16 V) or less is applied, The liquid crystal does not operate at all, and it is considered that no malfunction occurs. That is, in the first embodiment, the liquid crystal is prevented from malfunctioning between the lead lines 2W by allowing the electric field to escape in a direction in which the liquid crystal does not malfunction even when a slight voltage difference is applied.

  When a large charge is applied to the dummy pattern 2D due to external static electricity or the like, the liquid crystal between the lead line 2W and the dummy pattern 2D may malfunction and a new display defect may occur. In order to avoid this, in this embodiment, the dummy pattern 2D and the routing line 2W are not overlapped when the substrate plane is viewed from above, so that even if a malfunction occurs, it cannot be visually observed. The distance between the dummy pattern 2D and the routing line 2W when the substrate plane is viewed from above is ideally 0 to 20 μm. Even if it overlaps, if it is 0-20 micrometers which is a grade which cannot be visually confirmed, since malfunction by static electricity is a temporary problem, it is thought that there is no problem.

  FIG. 4 is a schematic cross-sectional view of the liquid crystal display element 102 for explaining the configuration and manufacturing method of the segment electrode pattern substrate and the common electrode pattern substrate according to the second embodiment of the present invention. In addition, the same reference number is attached | subjected to the member similar to 1st Example, and the description is abbreviate | omitted.

  The basic manufacturing method of the liquid crystal display element 102 according to the second embodiment is the same as that of the first embodiment described above. The differences from the first embodiment are the following three points.

  (1) The thin dummy patterns 2D2 are formed on the common electrode pattern substrate 1B when the substrate plane is viewed from above, between the routing lines 2W that may cause malfunction on the segment electrode pattern substrate.

  (2) The dummy pattern 2D2 is connected to the takeout terminal and connected to the circuit.

  (3) The voltage connected to the dummy pattern 2D2 is the same as the voltage applied to one of the two lead wires 2W formed at the boundary between the ground and the dummy pattern 2D2, or both lead wires 2W. One of the intermediate voltages applied to the. The voltages applied to the plurality of dummy patterns 2D2 are the same.

  In the second embodiment, the width of the dummy pattern 2D2 formed between the routing lines 2W is preferably 5 to 20 μm. In this case, the line width of the dummy pattern 2D2 becomes very thin and a sufficient voltage may not be applied. However, since display is not performed using this voltage, there is no problem.

  In the second embodiment, the portion where the dummy pattern 2D2 is formed is the distance between the electrodes of the lead-out line 2W in the segment electrode pattern 2 formed on the electrode surface of the segment electrode pattern substrate 1A, as in the first embodiment. Is 100 μm or less (actually manufactured with a line width of 100 μm and a distance between lines of 30 μm), and the angle Φ formed by the rubbing direction and the drawing line direction is −30 ° <Φ <30 ° or 60 ° <Φ < In the region of 120 °, in other words, the region in which the orientation between the lead lines and the liquid crystal alignment orientation at the center of the liquid crystal layer form an angle of 45 ° ± 30 °, the electrodes of the lead lines 2W on the common electrode pattern substrate 1B facing each other It is a part corresponding to between. The difference from the first embodiment is that, in the first embodiment, one dummy pattern 2D is formed in an island shape with respect to two adjacent lead lines 2W, whereas the second embodiment is different from the first embodiment. Then, a thin dummy pattern 2D2 is formed for each of two adjacent lead lines 2W.

  The connection line for applying a voltage to the dummy pattern 2D2 is routed on the common electrode pattern substrate 1B corresponding to the space between the lead lines 2W of the segment electrode pattern 2 where the distance between the lead lines 2W is larger than 100 μm. . If the user cannot observe the display of the liquid crystal display (outside the display part), the connection line for applying a voltage to the dummy pattern 2D2 can be freely routed on the common electrode pattern substrate 1B.

  The dummy pattern 2D2 and the connection line pattern for applying a voltage to the dummy pattern 2D2 can be produced at the same time when the common electrode pattern 2 is formed by adding the pattern at the time of designing the photomask pattern. The dummy electrode pattern 2D2 is preferably not overlapped with the pattern of the lead-out line 2W when the segment electrode pattern substrate 1A and the common electrode pattern substrate 1B are overlapped and viewed from the substrate plane. In consideration of the above, it is desirable that the wiring line is formed so as to be separated from the pattern of the drawing line 2W by about 5 to 20 μm.

  When the liquid crystal display element according to the second embodiment of the present invention manufactured as described above is driven by applying a 5V AC voltage by static drive and visually observed, the malfunction due to the lead line observed in FIG. It was not confirmed.

  In the second embodiment of the present invention, as shown in FIG. 4, even if a potential difference occurs between the routing lines 2W, the routing lines 2W and the counter substrate (common electrode pattern substrate) are more than the distance between the routing lines 2W. ) The distance from the dummy pattern 2D2 formed on 1A is shorter (distance between the lead lines 2W: 30 to 100 μm, distance between the lead lines 2W and the dummy pattern 2D2 (cell thickness): 6 to 30 μm). Therefore, as shown in FIG. 4, the direction of the electric field is applied between the lead line 2W and the dummy pattern 2D2, that is, approximately in the cell thickness direction. Since the liquid crystal molecules in the cell thickness direction are arranged in a state of being substantially lying with respect to the electric field direction (not substantially inclined with respect to the electric field direction), even if a voltage of a threshold value (2.16 V) or less is applied, The liquid crystal does not operate at all, and it is considered that no malfunction occurs. That is, also in the second embodiment, the liquid crystal is prevented from malfunctioning between the lead lines 2W by allowing the electric field to escape in a direction in which the liquid crystal does not malfunction even if a slight voltage difference is applied. Furthermore, in the second embodiment, it is possible to apply a voltage that is the same as or very close to the voltage applied to any one of the routing lines 2W through the connection line to all of the dummy patterns 2D2. An even greater malfunction suppression function than in the embodiment can be expected.

  When a large charge is applied to the dummy pattern 2D2 due to external static electricity or the like, the liquid crystal between the lead line 2W and the dummy pattern 2D2 may malfunction and a new display defect may occur. In order to avoid this, in this embodiment, the dummy pattern 2D2 and the routing line 2W are not overlapped when the substrate plane is viewed from above, so that even if a malfunction occurs, it cannot be visually observed. The amount of overlap between the dummy pattern 2D2 and the routing line 2W when the substrate plane is viewed from above is ideally 0 to 20 μm. Even if they overlap, if they are 20 μm or less, which cannot be confirmed by visual observation, malfunction due to static electricity is a temporary problem, so it is considered that there is no problem.

  Furthermore, in the second embodiment, since the dummy pattern 2D2 is connected to the circuit through the connection line, it can be considered that the circuit can be discharged through the connection line even if static electricity is applied. Actually, no malfunction was confirmed even when static electricity was positively applied to the manufactured liquid crystal display element.

  As described above, according to the embodiment of the present invention, among the segment electrode patterns formed on the electrode surface of the segment electrode pattern substrate, the distance between the lead lines is 100 μm or less, and the angle formed between the rubbing direction and the lead line direction In a region where Φ is −30 ° <Φ <30 ° or 60 ° <Φ <120 °, in other words, in a region where the orientation between the lead lines and the liquid crystal alignment direction in the central portion of the liquid crystal layer form an angle of 45 ° ± 30 °. By forming a dummy transparent electrode film (dummy electrode pattern) in a portion corresponding to between the electrodes of the lead lines on the common electrode pattern substrate facing each other, it is possible to suppress malfunction of the liquid crystal display between the lead lines. Can do.

  Further, since the dummy transparent electrode film (dummy electrode pattern) can be formed at the same time when the common electrode pattern is formed only by adding the pattern when designing the photomask pattern, no additional process is required. Therefore, an increase in cost can be suppressed.

  In addition, the dummy pattern and the lead-out line are not overlapped when the substrate plane is viewed from above, and even if a malfunction occurs, the dummy pattern and the lead line cannot be visually observed, thereby reducing the influence of malfunction due to static electricity. Further, by connecting the dummy transparent electrode film (dummy electrode pattern) to the circuit through the connection line, it is possible to prevent the malfunction due to static electricity.

  The embodiment of the present invention can be applied to information display-related in general, such as an in-vehicle display, a display for play, a display for a mobile phone / digital camera, and a display for audio equipment. In addition, the case where this embodiment is applied to a part of the display instead of the entire display is included. In particular, it is effective when applied to a negative display and a display with a bright backlight.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.

  For example, the relationship between the lead wire 2W and grounding / non-grounding is not limited to the combination of the above embodiments. Further, the shape and size of the dummy pattern are not limited to those of the above embodiments. Furthermore, the cell conditions of the liquid crystal cell are not limited to those of the embodiment.

  In addition, when the inter-electrode distance between the lead lines in the segment electrode pattern formed on the electrode surface of the segment electrode pattern substrate is 100 μm or less, the angle Φ formed by the rubbing direction and the lead line direction is −30 ° <Φ <30. Even in a region where ° or 60 ° <Φ <120 °, a dummy transparent electrode film (dummy electrode pattern) is formed on a portion corresponding to the electrode between the lead lines on the common electrode pattern substrate facing each other.
