Description

【０００１】
【発明の属する技術分野】
本発明は、電気光学装置に関する。詳しくはカラーフィルター層を有する電気光学装置の構造に関する。
【０００２】
【従来の技術】
従来、カラーフィルター上に透明電極を形成する方法として特開昭６１−２３３７２００号公報、特開昭６１−２６０２４号公報や特開昭６１−１９８１３１号公報又は特開昭６２−１５３８２６号公報の様にカラーフィルター及び、保護層等の形状、材質について種々提案されている。
【０００３】
【発明が解決しようとする課題】
しかしながら前述の従来技術では、細密パターンに対応し、形成を容易にする為カラーフィルター及び保護層が有機樹脂で形成されており、実際にカラーフィルター上に直接又は、前述の従来技術で提案されているように保護層を介して透明電極を形成する場合、有機樹脂の耐熱性が低くせいぜい２２０〜２３０℃の為、成膜時に温度が上げられず透明電極の膜質が弱く、例えば表面硬度が低く物理的強度が無い、水等の電界質が存在している環境下で電界をかけると電蝕反応が起こり化学的強度が無い等の問題を有していた。この問題は電気光学装置の信頼性が低いという大きな問題ともなっている。そこで、カラーフィルター自体の耐熱性向上の為、従来染色法により形成されていたカラーフィルターを顔料にする事が行われているが保持する樹脂自体の耐熱性に問題が有り飛躍的な向上は無い。また、樹脂の耐熱性を向上させる試みが成されているが、耐熱性を上げると短波長側での光の吸収が有り黄変してしまう、アルカリに対して耐性が劣る等の問題を有しており十分では無い。
【０００４】
他の方法として多孔質の無機層に顔料等の耐熱性の高い物を昇華させカラーフィルターを形成する方法等が提案されているがパターン精度、色純度等課題が多く検討の必要が有る。
【０００５】
そこで、本発明はこの様な問題点を解決するもので、その目的とする所は、カラーフィルター上に直接もしくは一層以上の有機、または無機層を介して透明電極を形成した電気光学装置の化学的耐性、特に電蝕反応に対して耐性を向上させ容易に信頼性の高い電気光学装置を提供する事にある。
【０００６】
【課題を解決するための手段】
本発明の液晶装置は、液晶装置において、一方の基板と、前記一方の基板の端部から張り出す張り出し部分を有する他方の基板と、前記一方の基板及び前記他方の基板間に狭持されるシール部材と、前記他方の基板の内面側に設けられ、前記シール部材の内側に位置する電極部分および前記シール部材の外側に位置する前記張り出し部分に延設される電極部分を有し、前記張り出し部分において信号入力部を有する電極と、前記シール部材の内側に位置する電極部分上および前記シール部材の外側に位置する前記張り出し部分に延設される前記電極部分上に設けられ、且つ前記信号入力部上に設けられない配向膜と、を備えることを特徴とする。
【０００７】
また、本発明は、前記他方の基板と前記電極との間に設けられる有機樹脂層を備え、前記有機樹脂層は、前記シール部材の内側位置、前記シール部材の位置に対応する位置および前記シール部材の外側位置に設けられ、前記有機樹脂層の端部は前記シール部材の外側に位置し、前記端部と前記他方の基板とで段差が形成されてなり、前記電極は前記段差をこえて前記他方の基板上まで連続して形成されてなり、前記配向膜は前記電極の前記段差の位置に対応する部分上に設けられるとよい。
【０００８】
また、本発明は、前記他方の基板と前記電極との間に設けられる有機樹脂層を備え、前記有機樹脂層は、前記シール部材の内側位置から前記信号入力部の位置に対応する位置まで連続して形成されてなるとよい。
また、本発明は、前記他方の基板と前記電極との間に設けられる有機樹脂層を備え、
前記有機樹脂層は、前記シール部材の内側位置から前記他方の基板の端部まで同一の層で形成されてなるとよい。
【０００９】
〔作用〕
本発明の上記構成によれば、少なくともカラーフィルターを有した基板の配向膜の領域を対向する基板と重なる領域より外側まで延長する事により洗浄等の行程中で付着したイオン性の汚れが一番残り易い上下基板の重なった部分に配向膜より成る遮断層を形成した事になり、前記イオン性の汚れに水分が吸着され電界の中で起こる電蝕反応に対して透明電極を接せず耐性を向上するという作用を生じる。
【００１０】
【実施例】
以下、本発明を実施例に基づき、より詳細に説明する。
【００１１】
カラーフィルタの形成方法により色々な保護層の形成方法が有るため、以下実施例毎にカラーフィルタの形成方法を分けて説明する。但し、本発明の電気光学装置は本実施例以外のカラーフィルタ形成方法や、保護層の形成方法にも適用できることはいうまでもなく、材料等にも限定されないことはいうまでもない。また、配向膜の厚みは外気との接触を遮断する為には膜厚は厚い方が良く、望ましくは５０オングストローム以上、更に効果を上げるには２００オングストローム以上有る事が望ましい。
【００１２】
〔実施例１〕
図１、図２を用いて説明する。図１に本発明のカラーフィルター付き基板の断面図を示す。ガラス基板１上に赤、青、緑、の各顔料を分散させたインクをオフセット法によりストライプ状に厚さ１．５μｍで印刷しカラーフィルター２を形成する。その後アクリル系の樹脂をスクリーン印刷法で１０μｍ厚みで形成し研磨して平坦化させたのち１８０℃で２時間乾燥させて保護層３をガラス基板１の全面に形成した。該ガラス基板１の前記保護層３上に低温マグネトロンスパッタ法により１８０℃の成膜温度で酸化インジュウム−酸化スズ（以下ＩＴＯ）よりなる透明導電性膜を２０００オングストローム形成し、フォトリソグラフ法にて透明電極４をカラーフィルター２と直交する様に形成した。次に図２を用いて本発明の電気光学装置の構造を説明する。図１で示したガラス基板１と同じくガラス基板６上にＩＴＯにてマトリックス状に成るように対向電極７を形成する。この後ポリイミドを用いて配向膜５、８を３００〜４００オングストロームで各々形成しシール９及び、ギャップ材１０を介して液晶１１を封入した。本実施例においては左ねじれ２３０°、セルギャップ６μｍとした。この時、カラーフィルターの付いている基板１の配向膜５の位置を信号入力部Ｂを除いて対向する基板６と重なる位置Ａより図２に示す様に寸法ａだけ延出して形成した。本実施例においてａの長さを振り比較したので以下に示す。まず、液晶を封入した電気光学装置をトリエタン等の有機溶剤中で洗浄し、次いで信号入力部等に付着した汚れを除去する為アルカリ水中（２〜４ｗｔ％）でブラッシングを行った。その後、時分割駆動による駆動波形を１／２００〜１／４０００デューティーで印加し５０℃−９０ＲＨ％下の環境下で２００時間連続通電試験を行い断線等の発生を調査した。５０時間毎に取り出し断線数とその内容を検査した。結果を表１にまとめる。今回のライン数は２００本で統一した。尚、電気光学装置の洗浄方法であるがアルカリ性の界面活性剤中で超音波洗浄をしても良く信号入力部等に傷の発生など物理的なダメージやシール部、保護層などへの洗浄剤からの化学的ダメージが無い限りその方法の選択には制限が無い。本実施例においてはアルカリ水中（２〜４ｗｔ％）でナイロン回転ブラシによるブラッシングを行った。回転ブラシによる傷付き性を考慮しブラシの当りは毛先が軽く接触する程度とした。

【００１５】
表１の結果より配向膜の位置がＡ部より少しでも外側に有れば本発明の効果が出る事が分かる。本実施例においては配向膜としてポリイミドを用いたが、他の配向剤、例えばプレイミド、ポリアミック酸、ポリアミド−イミド等制約は受けない。
【００１６】
〔実施例２〕
図３、図４を用いて説明する。図３に本発明のカラーフィルター付き基板の断面図を示す。ガラス基板１上に実施例１と同様にオフセット印刷法によりカラーフィルターをストライプ状に印刷後プレス加圧してカラーフィルター１２を平坦化して形成した。次に、エポキシアクリレート樹脂に紫外線感光性を付与してスピンコート法により１．２μｍ厚でコートした後、紫外線照射して保護層１３を選択的に形成した。その後、透明電極４を実施例１と同様に形成した。次に、図４を用いて電気光学装置の構成を説明する。本実施例においては実施例１と同様にカラーフィルター付き基板側の配向膜５の位置Ａと保護層１３の端部位置Ｃの双方を考慮して調査した。尚、電気光学装置のその他の構成は実施例１と同様にて形成した。電気光学装置の洗浄方法や試験方法については実施例１と同様に行い比較し易い様にした。
【００１７】
結果を表２にまとめる。Ｃ部位置についてはシール９の内側を（内）、外側を（外）とした。
【００１８】
表２：通電試験結果
【００１９】
【表２】

【００２０】
表２の結果より保護層１３が有る境界部が外気と接触し易い場合（シール９より外側）ＩＴＯの強度が弱く電蝕反応が発生し易い。この場合でも配向膜５が少なくともＡ部より外側に有れば効果を発揮する事が分かる。尚、シール９の下まで保護層１３を形成した方が液晶の厚みを制御し易く、その意味からも本発明の方法により保護層１３の形成位置の自由度が増す事も分かる。
【００２１】
実施例１，２を通じて説明してきたが、本発明の構造は他のカラーフィルター形成方法（例えば電着法、ポリイミド系基質等に顔料を分散させる方法、顔料を紫外線等の光感光性の有る基質に分散させフォト法によりパターニングする方法等）や保護層として他の材料（例えば熱硬化性メラミン樹脂、エポキシ樹脂、シリコーン系樹脂等）による制約は受けない。また、カラーフィルター付き基板の両側に信号入力部を形成する場合は同じ様に両側に配向膜を形成すれば良く、片側に有る場合、信号入力部と反対側は、特に制約は無くシールより外に出しても出さなくても良い。対向基板については何等制限を受けない。
【００２２】
〔実施例３〕
図５を用いて説明する。実施例１，２で説明してきた電気光学装置を調光用セル▲１▼とし、該調光用セル▲１▼と同じ光学特性（セルギャップ：ｄ／液晶もしくは光学的異方体の屈折率異方性：△ｎの積ｄｘ△ｎの値が同じ）を持つようにした光学的異方体▲２▼を偏光体１４，１５の間に設置した。本実施例では調光用セル▲１▼と同じ液晶を逆ねじれ（右）で同じセルギャップで形成し調光用セル▲１▼と光学的異方体▲２▼の相接する面の配向方向のなす角を９０°とし各々の偏光体の偏光軸と電気光学装置▲１▼と光学的異方体▲２▼各々の配向方向のなす角を２０〜５０°で振り全点灯時に白となる様に調整したところ、コントラストの高い、白、黒、表示可能な電気光学装置を形成できた。尚、光学的異方体としてフィルムでも同様の結果を得る事ができる。
【００２３】
【発明の効果】
上記のように、本発明のよれば、イオン性付着物に水分が吸着し、駆動時に印可される電界で発生する電蝕反応を遮断することにより電極の断線を防止し、信頼性が高く高品位の電気光学装置を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electro-optical device. Specifically, the present invention relates to a structure of an electro-optical device having a color filter layer.
[0002]
[Prior art]
Conventionally, a method for forming a transparent electrode on a color filter is disclosed in JP-A-61-2337200, JP-A-61-26024, JP-A-61-198131 or JP-A-62-153826. Various proposals have been made on the shape and material of the color filter and the protective layer.
[0003]
[Problems to be solved by the invention]
However, in the above-described prior art, the color filter and the protective layer are formed of an organic resin in order to correspond to a fine pattern and to facilitate formation, and are actually proposed directly on the color filter or in the above-described prior art. When a transparent electrode is formed via a protective layer as described above, the heat resistance of the organic resin is at most 220 to 230 ° C., so that the temperature is not increased during film formation and the film quality of the transparent electrode is weak, for example, the surface hardness is low. There is a problem that there is no physical strength, and when an electric field is applied in an environment in which an electrolyte such as water exists, an electrolytic corrosion reaction occurs and there is no chemical strength. This problem is also a major problem that the reliability of the electro-optical device is low. Therefore, in order to improve the heat resistance of the color filter itself, a color filter formed by a conventional dyeing method has been used as a pigment, but there is a problem in the heat resistance of the resin itself to be held and there is no dramatic improvement. . Attempts have been made to improve the heat resistance of the resin. However, increasing the heat resistance causes problems such as absorption of light on the short wavelength side and yellowing, and poor resistance to alkali. It is not enough.
[0004]
As another method, a method of sublimating a highly heat-resistant substance such as a pigment on a porous inorganic layer to form a color filter or the like has been proposed. However, many problems such as pattern accuracy and color purity need to be examined.
[0005]
Therefore, the present invention solves such a problem, and an object thereof is to provide a chemical reaction of an electro-optical device in which a transparent electrode is formed directly on a color filter or through one or more organic or inorganic layers. It is an object of the present invention to provide an electro-optical device which has improved electrical resistance, particularly resistance to an electrolytic corrosion reaction, and is easily and highly reliable.
[0006]
[Means for Solving the Problems]
A liquid crystal device of the present invention is a liquid crystal device, wherein one substrate, the other substrate having an overhang portion protruding from an end of the one substrate, and the one substrate and the other substrate are sandwiched between the one substrate and the other substrate. A sealing member, and an electrode portion provided on the inner surface side of the other substrate, the electrode portion extending inside the sealing member and the electrode portion extending outside the sealing member. An electrode having a signal input portion in the portion, and an electrode portion provided on the electrode portion located inside the seal member and on the electrode portion extending on the overhang portion located outside the seal member; and And an alignment film not provided on the portion.
[0007]
The present invention further includes an organic resin layer provided between the other substrate and the electrode, wherein the organic resin layer includes an inner position of the seal member, a position corresponding to the position of the seal member, and the seal member. An end of the organic resin layer is provided outside the member, and an end of the organic resin layer is located outside the seal member, and a step is formed between the end and the other substrate, and the electrode is over the step. The alignment film may be formed continuously on the other substrate, and the alignment film may be provided on a portion of the electrode corresponding to the position of the step .
[0008]
Further, the present invention includes an organic resin layer provided between the other substrate and the electrode, wherein the organic resin layer is continuous from a position inside the seal member to a position corresponding to the position of the signal input unit. It is good to be formed .
Further, the present invention includes an organic resin layer provided between the other substrate and the electrode,
The organic resin layer may be formed of the same layer from a position inside the seal member to an end of the other substrate.
[0009]
[Action]
According to the above configuration of the present invention, at least the region of the alignment film of the substrate having the color filter is extended to the outside of the region overlapping with the opposing substrate, so that ionic dirt adhered during a process such as cleaning is the most. A blocking layer made of an alignment film is formed in an overlapped portion of the upper and lower substrates, which is likely to remain, so that moisture is adsorbed by the ionic dirt and the electrode is resistant to an electrolytic corrosion reaction occurring in an electric field without contacting the transparent electrode. The effect of improving is produced.
[0010]
【Example】
Hereinafter, the present invention will be described in more detail based on examples.
[0011]
Since there are various methods of forming the protective layer depending on the method of forming the color filter, the method of forming the color filter will be described separately for each embodiment. However, it goes without saying that the electro-optical device of the present invention can be applied to a method of forming a color filter and a method of forming a protective layer other than those in this embodiment, and it is needless to say that the material is not limited. The thickness of the alignment film is preferably large in order to cut off contact with the outside air, more preferably 50 Å or more, and more preferably 200 Å or more for further improving the effect.
[0012]
[Example 1]
This will be described with reference to FIGS. FIG. 1 is a sectional view of a substrate with a color filter of the present invention. An ink in which red, blue, and green pigments are dispersed is printed on a glass substrate 1 in a striped shape with a thickness of 1.5 μm by an offset method to form a color filter 2. Thereafter, an acrylic resin was formed to a thickness of 10 μm by a screen printing method, polished and flattened, and then dried at 180 ° C. for 2 hours to form a protective layer 3 on the entire surface of the glass substrate 1. A transparent conductive film made of indium oxide-tin oxide (hereinafter referred to as ITO) was formed on the protective layer 3 of the glass substrate 1 at a film forming temperature of 180 ° C. by a low-temperature magnetron sputtering method at 2000 Å, and the transparent conductive film was formed by a photolithographic method. The electrode 4 was formed so as to be orthogonal to the color filter 2. Next, the structure of the electro-optical device of the present invention will be described with reference to FIG. The counter electrode 7 is formed on the glass substrate 6 in the same manner as the glass substrate 1 shown in FIG. Thereafter, alignment films 5 and 8 were formed at 300 to 400 angstroms using polyimide, respectively, and liquid crystal 11 was sealed through a seal 9 and a gap material 10. In this embodiment, the left twist was 230 ° and the cell gap was 6 μm. At this time, the position of the alignment film 5 of the substrate 1 having the color filter was extended by a dimension a as shown in FIG. In the present embodiment, the length a is compared and shown below. First, the electro-optical device enclosing the liquid crystal was washed in an organic solvent such as triethane, and then brushed in alkaline water (2 to 4 wt%) to remove stains attached to the signal input portion and the like. Thereafter, a drive waveform by time-division driving was applied at a duty of 1/200 to 1/4000, and a continuous energization test was performed for 200 hours in an environment under 50 ° C. and 90 RH% to investigate occurrence of disconnection and the like. Every 50 hours, the number of disconnections and the number of disconnections were examined. The results are summarized in Table 1. The number of lines this time was unified with 200 lines. The cleaning method of the electro-optical device may be performed by ultrasonic cleaning in an alkaline surfactant, or a cleaning agent for a physical damage such as generation of a scratch on a signal input portion or the like, a seal portion, a protective layer, or the like. There is no limit to the choice of method as long as there is no chemical damage from. In this example, brushing was performed with a nylon rotating brush in alkaline water (2 to 4 wt%). Considering the scratching property of the rotating brush, the contact of the brush was set to such a degree that the tip of the brush touched lightly.
[0013]
Table 1: Results of current test
[Table 1]

[0015]
From the results shown in Table 1, it can be seen that the effect of the present invention can be obtained if the position of the alignment film is slightly outside the portion A. In the present embodiment, polyimide is used as the alignment film, but there is no restriction on other alignment agents such as preimide, polyamic acid, and polyamide-imide.
[0016]
[Example 2]
This will be described with reference to FIGS. FIG. 3 shows a cross-sectional view of the substrate with a color filter of the present invention. A color filter was printed in a stripe shape on the glass substrate 1 by offset printing in the same manner as in Example 1, and then press-pressed to flatten the color filter 12 to form the color filter. Next, the epoxy acrylate resin was provided with ultraviolet sensitivity and coated by a spin coating method to a thickness of 1.2 μm, and then irradiated with ultraviolet light to selectively form the protective layer 13. Thereafter, a transparent electrode 4 was formed in the same manner as in Example 1. Next, the configuration of the electro-optical device will be described with reference to FIG. In the present embodiment, as in the case of the first embodiment, the investigation was performed in consideration of both the position A of the alignment film 5 on the substrate side with the color filter and the end position C of the protective layer 13. The other configuration of the electro-optical device was formed in the same manner as in Example 1. The cleaning method and the test method of the electro-optical device were performed in the same manner as in Example 1 so that comparison was easy.
[0017]
The results are summarized in Table 2. Regarding the position of the portion C, the inside of the seal 9 is (inside) and the outside is (outside).
[0018]
Table 2: Electricity test results
[Table 2]

[0020]
According to the results shown in Table 2, when the boundary portion where the protective layer 13 is present is likely to come into contact with the outside air (outside the seal 9), the strength of ITO is weak and an electrolytic corrosion reaction is likely to occur. Even in this case, it can be seen that the effect is exhibited if the alignment film 5 is at least outside the portion A. It should be noted that forming the protective layer 13 below the seal 9 makes it easier to control the thickness of the liquid crystal, and from this point of view, it is also understood that the method of the present invention increases the degree of freedom in the position at which the protective layer 13 is formed.
[0021]
Although described through Examples 1 and 2, the structure of the present invention can be applied to other color filter forming methods (for example, an electrodeposition method, a method of dispersing a pigment in a polyimide-based substrate, or the like, And the protective layer is not restricted by other materials (for example, thermosetting melamine resin, epoxy resin, silicone resin, etc.). When signal input portions are formed on both sides of the substrate with a color filter, the alignment films may be formed on both sides in the same manner, and when the signal input portions are on one side, the opposite side to the signal input portion is not particularly restricted and is outside the seal. You do not have to put it out. There is no limitation on the counter substrate.
[0022]

14 and 15. In the present embodiment, the same liquid crystal as that of the light control cell (1) is formed with the same cell gap by reverse twisting (right), and the alignment of the contact surfaces of the light control cell (1) and the optically anisotropic body (2). The angle between the directions is 90 °, the angle between the polarization axis of each polarizer, the orientation direction of each of the electro-optical device (1) and the optically anisotropic body (2) is changed at 20 to 50 °, and the white and As a result, an electro-optical device with high contrast, white, black, and display was able to be formed. Similar results can be obtained with a film as the optically anisotropic body.
[0023]
