Description of the Related Art In recent years, liquid crystal display elements used in display devices such as office automation equipment have been improved in performance such as size and color, as well as high contrast, wide visualization, and uniform display. Higher display quality is required.

色純度、表面の平坦性の向上と共に、液晶表示素子の電
極基板の間隔を均一に保持する事が重要な要素となって
いる。In order to meet the demands for higher performance and higher display quality of this liquid crystal display element, the retardation film, the liquid crystal material, the cell structure are optimized, the color purity of the color filter, and the surface flatness. It is an important factor to keep the distance between the electrode substrates of the liquid crystal display device uniform as well.
【０００４】このため液晶表示素子にあっては、通常、
対向する電極基板間に所望の径を有する間隙剤を均一に
散布し、両電極基板間の間隔を均一に保持している。Therefore, in a liquid crystal display device, normally,
A space agent having a desired diameter is uniformly dispersed between the opposing electrode substrates to maintain a uniform space between both electrode substrates.
【０００５】しかしながら、一般に製造過程において、
両電極基板間に間隙剤を均一に散布する事は比較的容易

入工程等において、振動や液晶組成物の流動により間隙
剤が、散布時に配置された位置から動いてしまい、散布
状態が均一にならず片寄ってしまう場合を生じていた。However, in the manufacturing process,
Although it is relatively easy to evenly disperse the gap agent between the two electrode substrates, vibration or liquid crystal composition may occur in the liquid crystal cell assembling process or the liquid crystal composition injecting process that is performed until the liquid crystal display element is completed. Due to the flow of the substance, the interstitial agent moves from the position where it is disposed at the time of spraying, resulting in a case where the spraying state is not uniform and deviated.
【０００６】そして、間隙剤の片寄りによって両電極基
板間の間隔が不均一になると、液晶組成物による電気光

た。 更に、液晶セル中で間隙剤に片寄りを生じる際
に、配向膜表面が傷付けられ、配向不良を起こし、これ
によっても表示品位が低下されてしまう恐れが有った。
このため従来は、間隙剤表面に熱硬化型接着剤を付着

た後、パターニング処理を行い、所定の位置にレジスト
柱を形成する等により、所定の高さの間隙剤を電極基板
上に予め固定形成する方法等が検討されていた。When the gap between the two electrode substrates becomes non-uniform due to the deviation of the gap agent, the electro-optical characteristics of the liquid crystal composition become non-uniform, so that the display by the liquid crystal display element becomes non-uniform, resulting in a contrast. However, there is a problem in that display unevenness occurs, such as variations in image quality and wide visualization cannot be obtained, and display quality is significantly reduced. Further, when the gap agent is offset in the liquid crystal cell, the surface of the alignment film may be damaged, resulting in poor alignment, which may also deteriorate the display quality.
For this reason, conventionally, a thermosetting adhesive is attached to the surface of the interstitial agent, which is evenly dispersed on the electrode substrate, and then the electrode substrate is heated to adhere the interstitial agent to the electrode substrate and move the interstitial agent. Or a spacer with a predetermined diameter is mixed into the adhesive to print and solidify at a predetermined position on the entire surface of the substrate, or a resist material with a predetermined film thickness is applied and formed on the entire surface of the substrate, followed by patterning processing. Then, a method of forming a resist pillar at a predetermined position and fixing a gap agent having a predetermined height on the electrode substrate in advance has been studied.
【０００７】[0007]
【発明が解決しようとする課題】従来は、液晶セル内で
間隙剤が片寄るのを防止するため、熱硬化型接着剤を用
いて間隙剤を電極基板に接着したりあるいは所定の高さ
の間隙剤を電極基板上に予め固定形成する等していた。Conventionally, in order to prevent the gap agent from being unbalanced in the liquid crystal cell, the gap agent is adhered to the electrode substrate using a thermosetting adhesive, or the gap having a predetermined height is used. The agent was previously fixed and formed on the electrode substrate.
【０００８】このため、熱硬化型接着剤を使用する場合
にあっては間隙剤の均一な散布が難しく、間隙剤の散布
時に既に片寄りを生じてしまう惧れがあると共に、強力
な接着力を付与する事が出来ず、接着剤を使用するにも
かかわらず、間隙剤が動いてしまい、信頼性に劣るとい
う問題を生じていた。For this reason, when the thermosetting adhesive is used, it is difficult to evenly disperse the interstitial agent, and there is a risk that deviation will already occur during the dispersal of the interstitial agent and a strong adhesive force. However, despite the use of the adhesive, the interstitial agent moves, resulting in poor reliability.
【０００９】又所定高さの間隙剤を固定形成する場合に

いた。In the case of fixedly forming a space agent having a predetermined height, the step of forming the space agent is added to the step of forming the liquid crystal cell, the manufacturing process becomes complicated, and it takes time to manufacture. There was a problem of rising costs.
【００１０】そこで本発明は上記課題を除去するもの

提供する事を目的とする。Therefore, the present invention eliminates the above-mentioned problems. A liquid crystal display device that can be uniformly sprayed without impairing the dispersibility at the time of spraying a space agent, is easy to manufacture, and does not cause an increase in cost. It is an object of the present invention to provide a method for manufacturing the same and a liquid crystal display device.

In a method of manufacturing a liquid crystal display device, which comprises a space agent for holding the liquid crystal material, the space agent is sprayed by at least one of the electrode substrates by a spraying device through a space portion, and the spraying device causes the electrode substrate to disperse. The space agent is irradiated with ultraviolet light in the space.

On the other hand, the interstitial agent surface is irradiated by the ultraviolet light. By activating, after reaching the electrode substrate after spraying, the interstitial agent retains a strong adhesive force and is strongly reactively attached to the electrode substrate. Therefore, after being placed on the electrode substrate, the gap agent will not be biased due to vibration or liquid crystal inflow, and the alignment film will not be damaged, so that the contrast is uniform and a uniform wide viewing angle is achieved. It is possible to obtain a good display without image unevenness.

There is ZLI-2293
A liquid crystal composition 26 containing 0.7% by weight of S-811 as a chiral agent was injected into (manufactured by E.

良好であった。When the distribution state of the interstitial agent 27 of the liquid crystal display element 1 thus formed is examined by a microscope, it is found that the interstices 27 are uniformly dispersed in the vicinity of the injection port [A] as shown in FIG. About 10 interstitial agents 27 were arranged almost uniformly in the pixel portion of 0.3 mm square. Further, when this liquid crystal display device was used for black and white display and was driven and lit at 1/200 duty, the contrast ratio was 30: 1 and a very uniform display was obtained over the entire surface. In addition, as a vibration test, when a vibration of 100 Hz was applied at 1 atm for 20 minutes, the gap agent 2

Regarding the distribution of the porosity agent, in most places except for the vicinity of the injection port [B], about 10 porosity agents 27 were dispersed almost uniformly in the pixel portion of 0.3 mm square, but near the injection port [ B], 0.3 mm
About 6 pixels are arranged in the corner pixel portion, which is smaller than other portions.

At the time of spraying the interstitial agent 27 by the
No. 7 does not have adhesiveness, so the dispersibility and uniformity of spraying are not impaired. Moreover, the interstitial agent 27 after spraying is exposed to ultraviolet light before it reaches the second electrode substrate 11. Is activated, it is surely reactively adhered to the surface of the second alignment film 21. Therefore, the dispersion of the interstitial agent 27 on the surface of the second alignment film 21 is made uniform, and the liquid crystal is dispersed after the disposition. There is no fear of deviation in the liquid crystal cell due to the manufacturing process of the display element 1 or an impact such as vibration during display use.
