2. Description of the Related Art Conventionally, liquid crystal devices have been widely used in various electronic devices such as digital cameras, portable telephones, portable information terminals and the like. For example, liquid crystal devices are used to display numbers, characters, and other visible images.

As a conventional liquid crystal device, as shown in FIG. 8, for example, an element substrate 3a and a counter substrate 3b, which are a pair of substrates, are adhered to each other with a sealing material 2, and a gap formed between the substrates is formed. A liquid crystal device having a structure in which liquid crystal is sealed in a so-called cell gap is known. Now, assuming that this liquid crystal device is a TFD (Thin Film Diode) liquid crystal device, pixel electrodes 6 are formed in a dot matrix on the inner surface of the element substrate 3a.
On the inner surface of the counter substrate 3b, a plurality of stripe-shaped counter electrodes 8, that is, straight lines arranged in parallel with each other, that is, conductive lines are provided.

In a liquid crystal device using a stripe-shaped counter electrode 8 as shown in FIG.
Is often provided so as to be interposed between the sealing material 2 and the counter substrate 3b. The reason is as follows. That is, the input-side portion 8b of the counter electrode 8 has to be interposed between the sealing material 2 and the counter substrate 3b in terms of its function.
If the terminal 8a of the counter electrode 8 is not interposed between the sealing material 2 and the substrate 3b, an error occurs in the cell gap between the input portion 8b and the terminal 8a by the thickness of the counter substrate 8, and As a result, the cell gap becomes non-uniform. When the terminal 8a of the counter electrode 8 is interposed between the sealing material 2 and the counter substrate 3b in this manner, the counter electrode 8
Is often exposed to the outside of the sealing material 2.

[0005]

By the way, when manufacturing a liquid crystal device, an empty liquid crystal panel is immersed in a container storing the liquid crystal to inject the liquid crystal into a cell gap between the substrates. Injection methods are often employed. When this method is adopted, it is common to wash the periphery of the liquid crystal panel to remove unnecessary liquid crystals after the liquid crystal injection process is completed.

However, even when the above-described cleaning treatment is performed, it is often observed that the liquid crystal cannot be completely removed from the periphery of the liquid crystal panel. In this case, the liquid crystal partially remains around the liquid crystal panel, In addition, the liquid crystal often contains a dirt component.

As described above, when the liquid crystal remains around the liquid crystal panel and the remaining liquid crystal remains on the counter electrode 8 exposed to the outside of the sealing material, each of the counter electrodes 8 is interrupted. When a voltage is applied, electrolytic corrosion occurs in each of the electrodes 8 in the presence of the remaining liquid crystal, and the electrolytic corrosion proceeds along the counter electrode 8 toward the inside of the substrate. Defects may occur and display quality of the liquid crystal device may be impaired.

The present invention has been made in view of the above-mentioned problems, and has a terminal portion of a conductive wire, such as a stripe-shaped counter electrode, interposed between a sealing material and a substrate, and is provided with a spacer material. An object of the present invention is to prevent a display defect such as a linear defect from occurring even if liquid crystal is left unwashed around a liquid crystal panel in a liquid crystal device having a structure used as a liquid crystal panel.

[0009]

(1) In order to achieve the above object, a first liquid crystal device according to the present invention comprises a pair of substrates joined to each other by a sealing material, and a stripe formed on at least one of the substrates. A plurality of conductive lines formed in a shape, the conductive lines traversing a part of the sealing material at an input side portion thereof, and an end portion thereof extends to a vicinity of another part of the sealing material. The other end of the sealing material corresponding to the end portion, between the sealing material and the substrate, disposed on an extension of the conductive line and having substantially the same thickness as the conductive line; It is characterized in that a spacer material electrically insulated from the conductive wires is provided.

(2) A second liquid crystal device according to the present invention comprises:
It has a pair of substrates joined to each other by a sealing material, and a plurality of conductive lines formed in stripes on at least one of the substrates, and the conductive lines traverse a part of the sealing material at an input side portion thereof. In a liquid crystal device, the terminal end of which extends to the vicinity of the other part of the sealing material, the ends of the plurality of conductive lines extend outside the inner edge of the sealing material, and the conductive lines are inside the outer edge of the sealing material. Divided at a position outside the effective display area,
A part separated from the conductive line by the division is used as a spacer material for the substrate.

According to each of the liquid crystal devices having the above-mentioned structure according to the present invention, the extension of the conductive line is provided between the substrate and the sealing material corresponding to the terminal portion of the conductive line crossing the sealing member at the input side portion. Since the spacer material on the line and having substantially the same thickness as the conductive line is provided, the gap between the pair of substrates facing each other is made uniform at the position corresponding to the input side portion and the terminal end of the conductive line. Therefore, uniform dimensions can be set for the entire substrate. Note that the term “substantially” includes a case in which dimensions vary due to manufacturing or other reasons.

When a spacer material is provided between the sealing material and the substrate near the end of the conductive wire, the tip of the spacer material is exposed outside the sealing material due to a manufacturing error or the like. Sometimes. In this case, if the spacer material exposed to the outside of the seal material is in conduction with the conductive line, when the liquid crystal remains on the exposed portion of the spacer material after the cleaning process of the liquid crystal, the electrolytic corrosion proceeds and the line defect is caused. May occur. On the other hand, if the conduction between the spacer material and the conductive wire is cut off as in the present invention, even if liquid crystal remains in the exposed portion of the spacer material, the conductive wire can be prevented from being electrolytically corroded. .

(3) In each of the above liquid crystal devices, the pair of substrates can be constituted by an element substrate on which a non-linear element is formed and an opposing substrate opposed thereto. In that case, the conductive line can be considered as a stripe-shaped counter electrode formed on the counter substrate. As a non-linear element, a TFT (Thin Film Transistor) which is a three-terminal type non-linear element
And TFD (Thin Film Diod)
e) and so on.

Here, the TFD has a structure in which an insulating layer is sandwiched between a first electrode and a second electrode. Considering a liquid crystal device using this TFD, the liquid crystal device is formed by the TFD. The element substrate thus formed and the opposing substrate facing the element substrate are bonded to each other with a sealing material. When the present invention is applied to this TFD type liquid crystal device, a stripe-shaped counter electrode formed on the surface of a counter substrate may be used as the “conductive line”.

A sealing material forming step of forming a material, and a substrate bonding step of bonding the substrates via the sealing material, wherein when the pair of substrates are bonded to each other, the conductive wire is sealed at the input side thereof. In a liquid crystal device in which the terminal portion extends across the portion of the sealing material and extends near the other portion of the sealing material, the sealing material and the sealing material correspond to the other portion of the sealing material corresponding to the terminal portion of the conductive wire. A spacer material forming step of forming a spacer material having substantially the same thickness as the conductive lines and electrically insulating the conductive lines from the substrate. You. According to this method of manufacturing a liquid crystal device, the liquid crystal device described in (1) can be reliably formed.

(5) In the method of manufacturing a liquid crystal device according to the above (4), the spacer material forming step can be performed simultaneously with the conductive line forming step. In this case, when the conductive line is formed in a predetermined pattern, the spacer material is formed in a predetermined pattern using the same material as the conductive line. According to this method, since the spacer material is formed at the same time as the formation of the conductive line, the manufacturing process is simplified.

(6) The method for manufacturing a liquid crystal device described in the above (4) can be carried out as follows. That is, in the conductive line forming step, a conductive line is formed such that ends of the plurality of conductive lines extend outside the inner edge of the sealing material, and the spacer material forming step is performed after the conductive line forming step. At this time, the spacer material is formed by dividing the formed conductive line at a position inside the outer edge of the sealing material and outside the effective display area. According to this method, it is necessary to execute a dedicated process for forming the spacer material, but it is possible to simplify the mask pattern when forming the conductive lines. The cutting of the conductive wire can be performed by, for example, a cutting process using a laser beam.

(7) The method of manufacturing each of the above liquid crystal devices is as follows.
The present invention can be used to manufacture a liquid crystal device including an element substrate on which a non-linear element is formed and an opposing substrate facing the element substrate. In that case, the conductive line can be considered as a stripe-shaped counter electrode formed on the counter substrate. As the nonlinear element, a three-terminal type nonlinear element T
An FT (Thin Film Transistor), a TFD (Thin Film Diode) which is a two-terminal type nonlinear element, and the like are conceivable.

(8) An electronic apparatus according to the present invention is an electronic apparatus including the liquid crystal device having the above-described configuration. In many cases, it will be used as a visible image display part of the electronic device, that is, a part for displaying numbers, characters, and other information. However, the present invention is not limited to this. Examples of such an electronic device include a digital camera, a mobile phone, and a portable information terminal.

Hereinafter, a method for manufacturing the liquid crystal device 1 will be described with reference to an embodiment. FIG. 5 is a flowchart showing an embodiment of the manufacturing method. In this manufacturing method, the element substrate forming step including the steps S1 to S5 and the opposing substrate forming step including the steps S6 to S11 are separately performed.

First, an element substrate forming step (steps S1 to S1)
In S5), a large-area translucent substrate base material 23a as shown in FIG. 4 is prepared. The substrate base material 23a is formed of a translucent material such as glass, plastic, or the like. A plurality of liquid crystal panels, in this embodiment, four wirings 4 and TFD elements 7 are formed on the substrate base material 23a (Step S1).

In the ordinary method, the wiring 4 and the TFD element 7 are formed by, for example, the following processing. That is, the first layer of the wiring 4 and the first electrode of the TFD element 7 are formed by forming a predetermined pattern of tantalum (Ta) on the surface of the element substrate base material 23a. Next, an anodic oxidation treatment is performed using the Ta pattern as an anode, thereby forming an anodic oxide film on each of the first layer of the wiring 4 and the first electrode of the TFD element 7. Further, wirings 4 are formed on the anodic oxide films by, for example, chromium (Cr).
Is formed and the second electrode of the TFD element 7 is formed, thereby forming the wiring 4 and the TFD element 7.

After that, a pixel electrode 6 having a predetermined shape is formed by ITO (Indium Tin Oxide) or the like so as to overlap the tip of the second electrode of the TFD element 7 (step S2). Here, in the step of forming the TFD element 7, I
When TO or the like is used, the pixel electrode 6 can be formed integrally at the same time, so that the step of forming the element substrate can be shortened. Thereafter, an alignment film 17 is formed by forming a uniform thickness of polyimide, polyvinyl alcohol, or the like on the surface of the substrate on which the pixel electrode 6 is formed (Step S3).
Further, a rubbing process and other alignment processes are performed on the alignment film 17 (step S4). After that, the sealing material 2 is formed in a square ring shape by a method such as screen printing (step S5). An opening 2a for injecting liquid crystal is formed in a part of the annular sealing material 2.

A counter substrate forming step (steps S6 to S11) is performed separately from the above-described element substrate forming step. First, in FIG. 4, a large-area light-transmitting substrate base material 23b formed of a light-transmitting material such as glass or plastic is prepared, and the surface of the substrate base material 23b (see FIG.
(On the lower surface) of the liquid crystal panel, and in this embodiment, four color filters 11 are formed.
6). Next, an overcoat layer 14 (see FIG. 3) is formed on the color filter 11 to have a uniform thickness to smooth the surface (Step S7). Thereafter, a plurality of linear counter electrodes 8 are formed by ITO or the like. They are formed parallel to each other at regular intervals, that is, in a stripe shape (step S8).

In the above-described counter electrode forming step, first, as shown in FIG.
a is formed so as to extend outside the inner edge 2 c of the sealing material 2. Then, in step 9, as shown in FIG. 1, the opposing electrode 8 is cut off at a position inside the outer edge 2 b of the sealing material 2 and outside the effective display area V as shown by reference numeral D, As a result, a spacer material 9 that is electrically insulated from the counter electrode 8 is left between the sealing material 2 and the counter substrate 3b.

Since the opposing electrode 8 passes between the sealing material 2 and the opposing substrate 3b at the input side portion 8b, it is assumed that the opposing electrode 8 is near the end of the opposing electrode 8 (the area indicated by the symbol A). Unless the spacer material 9 is provided between the counter electrode substrate 3b and the input electrode portion 8b of the counter electrode 8 and the vicinity of the end thereof, the gap between the element substrate 3a and the counter substrate 3b, That is, there is a possibility that the cell gap becomes non-uniform and the display quality deteriorates.

On the other hand, as in the present embodiment, a spacer material 9 having substantially the same thickness as the counter electrode 8 is provided between the sealing material 2 and the substrate 3b in the vicinity A of the terminal end portion of the counter electrode 8. By intervening, it is possible to prevent the cell gap from becoming non-uniform as described above. Although various methods for cutting the counter electrode 8 can be considered, for example, a method of cutting by irradiating a laser beam can be used.

After the opposing electrode 8 is divided and the spacer material 9 is formed as described above, an alignment film 16 (see FIG. 3) having a uniform thickness is formed on the opposing electrode 8 and the like using polyimide or the like. (Step S10) Further, the alignment film 16 is subjected to an alignment process such as a rubbing process (Step S11). Thereby, the counter substrate base material is completed.

Thereafter, as shown in FIG. 4, the element substrate base material 23a and the opposing substrate base material 23b are joined to each other with the sealing material 2 interposed therebetween (step S12). 2 is cured (step S13). As a result, an empty liquid crystal panel substrate preform having a substrate structure for four liquid crystal panels and no liquid crystal sealed therein is formed.

Thereafter, scribe grooves, that is, cutting grooves are formed at predetermined positions of the completed empty liquid crystal panel substrate base material, and the substrate base material is broken, that is, cut based on the scribe grooves (step S14). . As a result, a long empty liquid crystal panel base material in which the liquid crystal injection opening 2a of the sealing material 2 of each liquid crystal panel portion is exposed to the outside is formed.

Thereafter, liquid crystal is injected into each liquid crystal panel through the exposed liquid crystal injection opening 2a, and each opening 2a is sealed (step S15). In a normal liquid crystal injection process, for example, a liquid crystal is stored in a storage container under a reduced pressure (substantially vacuum) state, and a long empty liquid crystal panel is immersed in the stored liquid crystal. In this state, the pressure reduction is released and the liquid crystal in the storage container is pressurized. Since the liquid crystal adheres around the liquid crystal panel base material after the liquid crystal injection processing, the liquid crystal panel base material after the liquid crystal injection processing is subjected to the cleaning processing in step S16.
As a result, unnecessary liquid crystal containing a dirt component is removed from around the liquid crystal panel base material.

Thereafter, a scribe groove is formed again at a predetermined position in the elongated liquid crystal panel base material after the liquid crystal injection and washing are completed, and the liquid crystal panel base material is cut with reference to the scribe grooves. Thus, four liquid crystal panels are individually manufactured (Step S17). By mounting the liquid crystal driving ICs 18a and 18b on the individual liquid crystal panels thus manufactured, the target liquid crystal device 1
(FIG. 1) is completed.

With respect to the individual liquid crystal devices 1 manufactured as described above, as described above with reference to FIG.
Counter electrode 8 formed on light-transmitting substrate for counter substrate 3b
Since the spacer material 9 having the same thickness as the counter electrode 8 is interposed between the sealing material 2 and the substrate 3b located near the terminal portion (the area indicated by the arrow A) of the substrate 3a, between the substrates 3a and 3b The formed cell gap can be formed uniformly over the entire effective display region V.

The outer end of the spacer member 9 formed between the seal member 2 and the substrate 3a is hidden inside the seal member 2 or exposed to the outside of the seal member 2 according to the dimensional variation. Sometimes. Further, the removal of the liquid crystal remaining around the elongate liquid crystal panel base material in the cleaning step of step S16 in FIG. 5 is as described above. However, in some cases, the cleaning is not completely performed. In some cases, liquid crystals may remain.

If it is assumed that liquid crystal remains at the spacer material 9 exposed outside the sealing material 2 and that the spacer material 9 and the counter electrode 8 are electrically connected, the plurality of counter electrodes 8 For example, when a relatively high voltage such as a selection voltage is alternately applied, an electric erosion occurs in the spacer material 9 connected to the opposing electrodes 8, and the electric erosion gradually occurs in the opposing surface of the liquid crystal panel. It is conceivable to proceed to the electrode 8. In this case, a so-called line defect occurs, and the display quality of the liquid crystal device 1 is significantly reduced.

On the other hand, according to the liquid crystal device 1 of the present embodiment, since the spacer material 9 and the counter electrode 8 are electrically insulated by the dividing portion D, the spacer material 9 is not eroded. In addition, even if electrolytic corrosion occurs, the electrolytic corrosion does not propagate to the counter electrode 8. As a result, the occurrence of the line defect can be reliably prevented.

In the above description, the stripe-shaped counter electrode 8 formed on the light-transmitting substrate for counter substrate 3b was considered as a conductive line requiring a spacer material. However, in FIG. 1, the wiring 4 formed on the translucent substrate 3a for an element substrate is considered as a conductive line.
The sealing material 2 and the substrate 3a located near the end of the wiring 4
The spacer material 9 may be provided between them, and the dividing portion D may be formed between the spacer material 9 and the wiring 4.

The spacer material 9 was formed by cutting the counter electrode 8 outside the effective display area V.

On the other hand, in the manufacturing method of this embodiment shown in FIG. 6, steps S8 and S9 in FIG.
In step 18, both the counter electrode 8 and the spacer material 9 (see FIG. 1) are simultaneously patterned by a well-known patterning process, for example, a photolithography process. That is, the spacer material 9, the counter electrode 8, and all of the dividing portions D between them are formed simultaneously.

Since the thickness of the spacer material is substantially the same as the thickness of the conductive line, the cell gap of the liquid crystal panel can be maintained at a uniform thickness over the entire effective display area. In addition, since the conduction between the spacer material and the conductive wire is interrupted, even if the liquid crystal remains in the exposed portion of the spacer material and the spacer material is thereby eroded, the erosion does not occur. Propagation to the line can be prevented, and thus the occurrence of linear defects can be prevented. Further, according to the method for manufacturing a liquid crystal device of the present invention, the liquid crystal device according to the present invention can be reliably manufactured.
