Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a liquid crystal cell using various liquid crystals such as a smectic liquid crystal such as an antiferroelectric liquid crystal and a nematic liquid crystal, and a method of manufacturing the same.

[0002]

2. Description of the Related Art A liquid crystal cell is manufactured as follows. That is, a band-shaped seal is formed on the outer peripheral portion of the inner peripheral surface of one of the two electrode substrates, and spacers and adhesion fine particles are sprayed on the alignment film which is the inner surface of the other electrode substrate. Then, the two electrode substrates are overlapped with a seal made of a thermosetting resin, a spacer and an adhesive fine particle interposed therebetween. Thereafter, a liquid crystal is manufactured by vacuum injection of liquid crystal between the two electrode substrates from a liquid crystal injection port of the seal. I do.

[0003]

By the way, in such a liquid crystal cell, the two electrode substrates are overlapped with each other in a softly sealed state, and are heated under pressure. Accordingly, the seal hardens while being crushed to a predetermined thickness by both electrode substrates. Therefore, in such a process, the inner peripheral surface 1a of the seal (see reference numeral 1 in FIG. 5) is used.
Are formed in an uneven shape in a direction along the inner surface of the electrode substrate. This means that the seal 1 is formed on the inner peripheral surface 1a in a form with extremely poor linearity.

Therefore, when the liquid crystal is injected into the space between the two electrode substrates by vacuum, bubbles (see reference numeral 2 in FIG. 5) are apt to be caught along the inner surface 1a of the seal 1, and as a result, both the bubbles 1 Unfilled regions of the liquid crystal are likely to occur due to the residue between the electrode substrates. In particular, when a smectic liquid crystal is adopted as the liquid crystal, due to residual bubbles between the two electrode substrates,
A liquid crystal unfilled region tends to grow in the layer direction of the smectic liquid crystal. Further, when the smectic liquid crystal directly contacts the inner peripheral surface 1a of the seal 1, an abnormal alignment of the smectic liquid crystal occurs at the interface between the smectic liquid crystal and the inner surface 1a of the seal 1. Along with this, this alignment abnormality grows in the layer direction of the smectic liquid crystal in the non-aligned region (the region between the seal 1 and the alignment film 4) in FIG. 5 (see the hatched region indicated by reference numeral 3 in FIG. 5). ).

Furthermore, when a negative pressure state is created between the two electrode substrates due to the volume shrinkage of the smectic liquid crystal due to the presence of residual air bubbles and an abnormal orientation at the interface between the smectic liquid crystal and the seal, the smectic liquid crystal becomes Opening between adjacent layers results in unfilled areas of smectic liquid crystal. In view of the above, the present invention has devised a structure between the seal and the liquid crystal in order to cope with the above-described problems, thereby preventing the generation and growth of alignment defects of the liquid crystal near the inner surface of the seal. It is an object to provide a liquid crystal cell and a method for manufacturing the same.

[0006]

In order to solve the above-mentioned problems, according to the first to fifth aspects of the present invention, the liquid crystal cell is a two-electrode substrate which is superimposed on each other, and each of the alignment films (21) is provided. The two electrode substrates (1
0, 20), a band-shaped seal (30) interposed between the two electrode substrates at the periphery thereof, and a liquid crystal sealed between the two electrode substrates via a seal.

Here, this liquid crystal cell is interposed between the two electrode substrates along a strip along the inner peripheral surface of the seal, and the inner peripheral surface is formed of a liquid crystal portion of the liquid crystal corresponding to the effective display area of the two electrode substrates. And an isolation partition (40) for isolating the partition. in this way,
Since the liquid crystal portion is isolated from the inner peripheral surface of the seal by the separating partition, the inner peripheral surface of the seal was formed into an uneven shape in the manufacturing process of the liquid crystal cell. Even if the liquid crystal is wound between the substrates along the inner peripheral surface of the seal, the liquid crystal does not directly contact the inner peripheral surface of the seal.

As a result, an abnormal alignment of the liquid crystal, which would occur when the liquid crystal comes into direct contact with the inner peripheral surface of the seal, the growth of an alignment defect caused by the abnormal liquid crystal, and a residual air bubble between the two electrode substrates. It is possible to provide a liquid crystal cell in which the generation and growth of an unfilled region of liquid crystal are reliably prevented. here,
According to the second aspect of the present invention, both alignment films are formed wider than the effective display area of both electrode substrates toward the inner peripheral surface of the seal, and the separating partition is formed on the outer periphery of both alignment films. It is interposed between clubs.

Thus, it is possible to provide a liquid crystal cell in which the alignment of the liquid crystal is more preferably ensured while achieving the function and effect of the first aspect. According to the third aspect of the present invention, there are provided a plurality of spacer partition walls (50) interposed between the two alignment films inside the partition wall, and the liquid crystal is a smectic liquid crystal. The film is formed wider than the effective display area of both electrode substrates toward the inner peripheral surface of the seal. The partition for isolation is interposed between the peripheral edges of both alignment films.

As described above, even when the liquid crystal is a smectic liquid crystal and a plurality of spacer partition walls are provided, the same operation and effect as the second aspect of the invention can be achieved. According to the fourth aspect of the present invention, the partition for isolation is made of a resist material. Accordingly, in the partition wall made of the resist material, irregularities are hardly formed on the inner peripheral surface in contact with the liquid crystal, so that the wettability with the liquid crystal is improved, and the prevention of entrapment of bubbles at the time of liquid crystal injection can be further improved.

According to the fifth aspect of the present invention, the separating partition and the plurality of spacer partitions are integrally formed of the same resist material. Thereby, in addition to the operation and effect of the invention described in claim 4, it is possible to simplify the manufacturing process of the partition for isolation and the partition for multiple spacers. According to a sixth aspect of the present invention, in the method for manufacturing a liquid crystal cell, the two electrode substrates (10, 20) are each provided with an alignment film (2).

S2), a rubbing step (S3, S6) of rubbing each alignment film (21) of both electrode substrates, and a thermosetting seal (30) on the inner surface peripheral portion of one (10) of both electrode substrates. Seal forming step of forming a band with resin (S4)
And an overlapping step of overlapping both electrode substrates (S8)
After this overlapping step, a seal curing step (S) in which a seal is cured while applying heat and pressure to both electrode substrates.
9) and after the seal hardening step, a liquid crystal injection step (S10) of injecting a liquid crystal between both electrode substrates via a part of the seal.

Here, this manufacturing method includes a partition forming step of forming a partition (40) in the form of a strip from a resist material along a portion corresponding to the inner peripheral surface of the seal on one inner surface of both electrode substrates. S5), and after this partition wall forming step,
A rubbing process is performed in a rubbing step.

In the case of manufacturing a liquid crystal cell in this way, even if liquid crystal is injected between the two electrode substrates in the liquid crystal injection step, a portion of the liquid crystal corresponding to the effective display area of the two electrode substrates remains. It is isolated from the inner peripheral surface of the seal by the isolation partition. Here, the partition wall made of the resist material is hardly formed with irregularities on the inner peripheral surface in contact with the liquid crystal, and has excellent linearity.
Good wettability of liquid crystal. For this reason, bubbles are not involved when the liquid crystal is injected.

Therefore, since the inner peripheral surface of the seal is formed in an uneven shape along the inner surface of the electrode substrate during the heating and pressurizing process in the seal curing step, air bubbles are generated between the two electrode substrates with the above injection. Even when the liquid crystal is wound along the inner peripheral surface of the seal, the liquid crystal does not directly contact the inner peripheral surface of the seal when the liquid crystal is injected. As a result, the alignment abnormality of the liquid crystal, which would occur when the liquid crystal directly contacts the inner peripheral surface of the seal, the growth of the alignment defect caused by the liquid crystal, and the liquid crystal not being caused by the residual bubbles between the two electrode substrates. The formation and growth of the filling region can be reliably prevented.

According to a seventh aspect of the present invention, in a method of manufacturing a liquid crystal cell, an electrode substrate forming step (S1) of forming both electrode substrates (10, 20) so as to have an alignment film (21), respectively. , S2) and a plurality of spacer partition walls (50) on the alignment film of one of the electrode substrates (20).
Forming step using a resist material (S12)
And a rubbing step of rubbing the alignment film of one electrode substrate through a plurality of spacer partition walls (50) and rubbing the alignment film of the other electrode substrate (S3, S6A)
And a seal forming step (S4) of forming a seal (30) in a strip shape from a thermosetting resin on one of the inner peripheral edges of both electrode substrates; and sealing both electrode substrates and a plurality of spacer partition walls. And a seal curing step (S9A) of curing the seal and the plurality of spacer partition walls while applying heat and pressure treatment to both electrode substrates after the overlapping step. After the seal hardening step, a liquid crystal injection step (S10A) of vacuum injection of liquid crystal between the two electrode substrates via a part of the seal is provided.

Here, in this liquid crystal cell manufacturing method, in the partition wall forming step (S12), the inner surface of one of the electrode substrates is formed along the inner peripheral surface of the seal between the seal and the plurality of spacer partition walls. Then, a partition wall (40) for isolation is formed in a strip shape with a resist material together with a plurality of spacer partition walls, and then a rubbing treatment in the rubbing step is performed.

In this way, unlike the invention according to claim 6, the isolation partition may be formed between the seal and the plurality of spacer partitions together with the plurality of spacer partitions. Accordingly, the same function and effect as the invention described in claim 6 can be achieved. According to an eighth aspect of the present invention, in the method for manufacturing a liquid crystal cell according to the sixth or seventh aspect, in the electrode substrate forming step, both alignment films are oriented toward the inner peripheral surface of the seal. Formed wider than the effective display area,
In the partition wall forming step, the partition wall for isolation is formed along the inner peripheral surface of the seal on one of the alignment films along the inner peripheral surface of the seal, and between the seal and the partition walls for plural spacers, together with the plural barrier ribs for the resist material. To form a strip.

As described above, since the partition for isolation is formed on the alignment film, the operation and effect of the invention according to claim 6 or 7 can be achieved while ensuring the alignment of the liquid crystal more favorably. According to a ninth aspect of the present invention, in the method for manufacturing a liquid crystal cell according to the sixth or seventh aspect, in the electrode substrate forming step, the two alignment films face the inner peripheral surface of the seal.

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 shows an example of a liquid crystal cell according to the present invention. This liquid crystal cell includes a lower electrode substrate 10,
And an upper electrode substrate 20.
Between 0 and 20, smectic liquid crystal is a band-shaped seal 30.
On the inner peripheral side, a partition 40 constituting a main part of the present invention, a number of spacers, and adhesive fine particles are interposed.

The electrode substrate 10 is formed by sequentially forming a plurality of color filter layers, a plurality of transparent electrodes, and an alignment film on the inner surface of a transparent substrate. On the other hand, the electrode substrate 20
A plurality of transparent electrodes and an alignment film 21 are sequentially formed on the inner surface of a transparent substrate. In addition, both electrode substrates 10,
The plurality of transparent electrodes 20 are arranged crossing each other to form a plurality of matrix-shaped pixels together with the smectic liquid crystal.

Here, as shown in FIG. 1, the alignment film 21 of the electrode substrate 20 has an area larger than the effective display area of the liquid crystal cell together with the alignment film of the electrode substrate 10. The partition wall 40 for isolation is formed in a U-shape on the inner surface of the alignment film 21 along the periphery thereof and inside the seal 30, and the partition wall 40 is formed of the alignment film 21 and the alignment film of the electrode substrate 20. And serves as a partition between the smectic liquid crystal and the seal 30. In addition,
In FIG. 1, reference numeral 31 indicates a liquid crystal injection port of the seal 30.

Next, a method of manufacturing the liquid crystal cell having the above-described structure will be described with reference to FIG. In the lower electrode substrate forming step S1 in FIG.
On the other hand, in the upper electrode substrate forming step S2, the upper electrode substrate 20 having the above configuration is formed.

Next, in a rubbing step S3, a rubbing process is performed on the alignment film of the lower electrode substrate 10. Then, in the seal printing step S4, a thermosetting resin is printed in a U-shape on the inner surface peripheral portion (located on the outer peripheral side of the alignment film of the electrode substrate 10) of the electrode substrate 10 to form the seal 30.
At this time, the liquid crystal injection port 31 is also formed. In the partition forming step S5, the partition 40 is formed on the peripheral portion of the alignment film 21 of the upper electrode substrate 20 as follows.

That is, a photoresist made of a phenolic resin is applied to the entire inner surface of the upper electrode substrate 20 including the inner surface of the alignment film 21 to form a photoresist film. Then, this photoresist film is subjected to exposure and development processing in a predetermined pattern (a pattern corresponding to the U-shaped partition wall 40) to form the partition wall 40 in a U-shape on the peripheral portion of the alignment film 21.

Thus, as described later, the two electrode substrates 1
When 0 and 20 are overlapped, the partition wall 40 is located on the outer peripheral surface so as to face the inner peripheral surface of the seal 30 when viewed from the portion corresponding to the effective display area on the inner surface of the electrode substrate 20. . Next, in a rubbing step S <b> 6, a rubbing process is performed on the alignment film 21 of the upper electrode substrate 20 via the partition wall 40. The rubbing direction for both alignment films is
When the two electrode substrates 10 and 20 are overlapped, the orientation direction of the smectic liquid crystal is regulated.

After this rubbing treatment, in the spacer / adhesion fine particle dispersing step S7, the alignment film 2 of the upper electrode substrate 20 is removed.
A large number of spacers and two electrode substrates 10 and 20 for regulating the cell gap of the liquid crystal cell inside the partition 40 on 1
A large number of adhesive fine particles are dispersed to hold the adhesive. Thereafter, in the superposition step S8, the two electrode substrates 10,
20 are superimposed via the seal 30, the partition wall 40, the spacer, and the adhesive fine particles. Then, in the seal hardening step S9, the seal 30, the partition wall 40, and the respective adhesive fine particles are hardened while applying heat and pressure to both of the electrode substrates 10, 20.

As a result, the distance between the two electrode substrates 10 and 20, that is, the cell gap is regulated by the spacers, and the two electrode substrates 10 and 20 are adhered and held by the respective adhesion fine particles. In addition, the partition wall 40 is sandwiched between the peripheral portions of the respective alignment films of the electrode substrates 10 and 20, and the inner peripheral surface of the seal 30 corresponds to the effective display area of the electrode substrates 10 and 20 of the smectic liquid crystal. Separated from the liquid crystal part.

Next, in a liquid crystal injection step S10, the smectic liquid crystal is heated and the two electrode substrates 10, 20 are heated.
The liquid crystal is injected from the liquid crystal injection port 31. Then, in the liquid crystal enclosing step S11, the liquid crystal injection port 31 is sealed.
Thus, the manufacture of the liquid crystal cell ends. In the liquid crystal cell manufactured as described above, in the liquid crystal injection step S10 as described above, the smectic liquid crystal is applied to both electrode substrates 10, 20.
The liquid crystal portion of the smectic liquid crystal, which corresponds to the effective display area, is sealed by the partition
0 is isolated from the inner peripheral surface.

Therefore, the inner peripheral surface of the seal 30 is heated during the heating and pressurizing process in the seal hardening step S9.
Is formed in an uneven shape along the inner surface of the substrate. Therefore, even if air bubbles are caught between the two electrode substrates 10 and 20 along the inner peripheral surface of the seal 30 due to the above-described injection, the effective display area of the smectic liquid crystal is The corresponding liquid crystal portion does not directly contact the inner peripheral surface of the seal 30 during the injection.

Here, since the partition wall 40 is formed by subjecting the photoresist film to exposure and development processing in a predetermined pattern, and then to heating and pressurizing processing, the inner peripheral surface of the partition wall 40 is
As compared with the above, irregularities are less likely to be formed and become linear. Thereby, the wettability between the smectic liquid crystal and the partition 40 is improved. As a result, the misalignment of the smectic liquid crystal that would occur when the smectic liquid crystal directly contacts the inner peripheral surface of the seal 30 and the growth of the alignment defect caused by the smectic liquid crystal, and the residual of the bubbles between the two electrode substrates 10 and 20. Therefore, it is possible to reliably prevent the generation and growth of an unfilled region of the smectic liquid crystal due to the above.

(Second Embodiment) FIG. 3 shows a liquid crystal cell according to a second embodiment of the present invention. This liquid crystal cell is
The liquid crystal cell described in the first embodiment has a configuration in which a plurality of spacer partition walls 50 are employed instead of a large number of spacers and a large number of adhesive fine particles.

Each of the partition walls 50 is sandwiched between the alignment film of the lower electrode substrate 10 and the alignment film 21 of the upper electrode substrate 20 corresponding to the effective display area. Thereby, each partition 50 performs the same function as each spacer and each adhesive fine particle described in the first embodiment. Other configurations are the same as those of the liquid crystal cell described in the first embodiment.

Next, a method of manufacturing the liquid crystal cell having such a configuration will be described with reference to FIG. As in the first embodiment, the lower electrode substrate forming step S1, the upper electrode substrate forming step S2, the rubbing step S3, and the seal printing step S
4 is performed. Thereby, the lower electrode substrate 10
, The upper electrode substrate 20, the rubbing treatment of the alignment film of the lower electrode substrate 10, and the formation of the seal 30 on the inner surface of the lower electrode substrate 10 are performed in the same manner as in the first embodiment.

Thereafter, in a partition forming step S12, the partition 40 and the plurality of partitions 50 are formed on the inner surface of the alignment film 21 of the upper electrode substrate 20 as follows. That is, a photoresist made of a phenolic resin is applied to the entire inner surface of the upper electrode substrate 20 including the inner surface of the alignment film 21 to form a photoresist film. Then, the photoresist film is subjected to exposure and development processing to a predetermined pattern (a pattern corresponding to the U-shaped partition wall 40 and the plurality of partition walls 50) to form the U-shaped partition wall 40 and the plurality of partition walls 50 integrally. Is formed on the inner surface of the alignment film 21. At this time, the U-shaped partition wall 40 is formed on the peripheral portion of the inner surface of the alignment film 21, and the plurality of partition walls 50 are formed inside the U-shaped partition wall 40 and in the effective display area. (See FIG. 3).

Thus, as will be described later, both electrode substrates 1
When 0 and 20 are overlapped, the partition wall 40 is located on the outer peripheral surface so as to face the inner peripheral surface of the seal 30 when viewed from the portion corresponding to the effective display area on the inner surface of the electrode substrate 20. At the same time, a plurality of partition walls 5
It is located to face 0. Then, rubbing step S6A
In the above, a partition wall 40 is formed on the alignment film 21 of the upper electrode substrate 20.
A rubbing process is performed along the longitudinal direction of the partition walls 50 through a plurality of partition walls 50. The rubbing direction for both alignment films regulates the alignment direction of the smectic liquid crystal when both electrode substrates 10 and 20 are overlapped.

After this rubbing treatment, a superposition step S8
In A, the two electrode substrates 10 and 20 are overlapped via a seal 30, a partition wall 40 and a plurality of partition walls 50. This overlapping is performed so that the partition 40 and the plurality of partitions 50 have the positional relationship shown in FIG. Then, in the seal hardening step S9A, the seal 30, the partition wall 40, and the plurality of partition walls 50 are hardened while applying heat and pressure to both the electrode substrates 10, 20.

As a result, the regulation of the cell gap between the two electrode substrates 10 and 20 and the adhesion and holding of the two electrode substrates 10 and 20 are performed by the partition walls 50. Further, similarly to the first embodiment, the partition wall 40 is sandwiched between the peripheral portions of the alignment films of both the electrode substrates 10 and 20, and the inner peripheral surface of the seal 30 is disposed between the two electrode substrates of the smectic liquid crystal. It is isolated from the liquid crystal portions corresponding to the effective display areas 10 and 20.

Next, in the liquid crystal injection step S10A,
When the smectic liquid crystal is heated, the two electrode substrates 10, 2
The liquid crystal is injected from the liquid crystal injection port 31 along the longitudinal direction of each partition 50 during 0. Thereafter, as in the first embodiment, in the liquid crystal enclosing step S11, the liquid crystal injection port 31 is sealed. Thus, the manufacture of the liquid crystal cell ends.

In the liquid crystal cell thus manufactured,
Even if the smectic liquid crystal is injected between the two electrode substrates 10 and 20 in the liquid crystal injection step S10A as described above, the liquid crystal portion of the smectic liquid crystal corresponding to the effective display region is formed around the inner periphery of the seal 30 by the partition wall 40. Isolated from the surface. Accordingly, since the inner peripheral surface of the seal 30 is formed in an uneven shape along the inner surface of the electrode substrate 20 during the heating and pressurizing process in the seal curing step S9A, air bubbles are generated with the above-described injection. Even if the liquid crystal portion of the smectic liquid crystal corresponding to the effective display area is not directly in contact with the inner peripheral surface of the seal 30 during the injection, even if the liquid crystal portion is wound along the inner peripheral surface of the seal 30 between the two. As a result, the same functions and effects as those of the first embodiment can be achieved.

In practicing the present invention, the liquid crystal cell may be composed of an electrode substrate without using a color filter layer, and the liquid crystal is not limited to a smectic liquid crystal but may be a liquid crystal such as a nematic liquid crystal. You may.
