【発明の詳細な説明】
本発明は、エレクトロクロミツク物質（EC）
を使用したEC調光体に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an electrochromic material (EC)
This is related to an EC light control body using.
光線を遮蔽するための調光体としては、従来は
ブラインド、カーテン等が用いられているが開閉
がめんどうであり、より細かい調整のきく調光体
が望まれている。 Conventionally, blinds, curtains, and the like have been used as light control bodies for blocking light rays, but they are troublesome to open and close, and a light control body that allows finer adjustment is desired.
近年、電気光学的に光線を遮蔽することにより
表示を行う素子として液晶表示素子（LCD）、エ
レクトロクロミツク表示素子（ECD）等が注目
されており、これらを調光体として使用するアイ
デアも種々提案されている。 In recent years, liquid crystal display devices (LCDs), electrochromic display devices (ECDs), and other devices have attracted attention as devices that display images by electro-optically shielding light, and there are various ideas for using these devices as light control devices. Proposed.
この内液晶では、液晶層は薄いという利点はあ
るが、偏光膜を使用すると耐候性が不充分でかつ
透過時の透過率が低いという欠点、基板間隙を一
定に保つのが困難である点、液晶が、熱、紫外線
に弱いという欠点等があり未だ実用化されていな
い。 Among these, liquid crystal has the advantage that the liquid crystal layer is thin, but the disadvantages are that the use of a polarizing film has insufficient weather resistance and low transmittance during transmission, and that it is difficult to maintain a constant gap between the substrates. Liquid crystals have disadvantages such as being sensitive to heat and ultraviolet light, so they have not yet been put into practical use.
ECを用いた表示体であるECDは、LCDに比し
て応答速度が遅い、着消色をくり返すと脱色、消
色不良等を生じ106〜107回程度の寿命しかなく時
計での秒表示ができない等の欠点があるため、そ
のコントラストが良い、着消色以外には電力を消
費しなくメモリー性があるという利点を有してい
るにもかかわらず、現在のところほとんど実用化
されていない。 ECD, which is a display using EC, has a slower response speed than LCD, and if it repeats coloring and decoloring, it will cause decolorization and decolorization failure, and has a lifespan of only about 10 6 to 10 7 times, so it cannot be used as a watch. Although it has the disadvantages of not being able to display seconds, it has the advantage that it has good contrast, does not consume power and has memory properties other than coloring and fading, but it has hardly been put into practical use at present. Not yet.
しかし、これらECDでは欠点となつた事項も
表示体でない調光体としてはほとんど問題となら
ない。即ち、調光体では１秒の何分の一という応
答速度は実質的に無意味で、通常数秒〜数分程度
の応答速度で充分であり、くり返し着消色による
寿命も１日10回着消して10年で約40000回と104〜
105回程度で実用に耐えるため何ら問題とならな
い。さらにECの利点であるコントラストが良い
こと、着消色以外には電力を要しないことはその
まま生かせる上に、液晶のように基板間隙の制御
がECと対向電極が短絡しない程度であれば良い
ため極めて容易にでき、調光体として製造するこ
とが容易である。 However, the drawbacks of these ECDs do not pose much of a problem when used as a light control body that is not a display body. In other words, for a light control body, a response speed of a fraction of a second is essentially meaningless, and a response speed of several seconds to several minutes is usually sufficient, and the lifespan due to repeated coloring and decoloring is limited to 10 times a day. Approximately 40,000 times in 10 years since I deleted it, 10 4 ~
10 It can withstand practical use after about 5 times, so there is no problem. Furthermore, the advantages of EC, such as good contrast and the fact that it does not require electricity for anything other than coloring and decoloring, can be utilized as is, and unlike liquid crystals, the gap between the substrates can be controlled as long as the EC and the counter electrode do not short-circuit. It is extremely easy to make and can be easily manufactured as a light control body.
これらの知見に基づき本発明者も調光体とし
て、その構成に関しすでに何件かの提案をしてき
ている。 Based on these findings, the present inventor has already made several proposals regarding the structure of a light control body.
しかし、EC調光体を実用化するためには、
ECDに比してはるかに大型化しなくてはならな
く新たな大きな問題が生じた。 However, in order to put EC dimmer into practical use,
It had to be much larger than the ECD, and a new big problem arose.
即ち、ECを使用したEC調光体では、着消色時
に一時的に大きな電力消費が行なわれ、電極に大
きな電流が流れる。このため調光体の周辺のリー
ド取り出し部付近では高い電圧が印加されるが、
そこから離れるに従い電圧が低下し、これにより
部分的に着色の濃淡があらわれることがあつた。 That is, in an EC light control body using EC, a large amount of power is temporarily consumed during coloring/decoloring, and a large current flows through the electrodes. For this reason, a high voltage is applied near the lead extraction part around the dimmer, but
The voltage decreased as the distance from the area increased, and as a result, the coloring sometimes appeared darker and lighter in parts.
本発明は、かかる色ムラを防止することを目的
としてなされたものであり、透明電極上にエレク
トロクロミツク物質層を形成した透明基板と、対
向電極を形成した透明基板とを電解質を介して積
層し、少なくとも一方の電極上に絶縁膜を形成し
たEC調光体において、該絶縁膜の膜厚を電極取
り出し部付近を厚くし、電極取り出し部から遠ざ
かるにつれて徐々に薄くしたことを特徴とする
EC調光体である。 The present invention was made with the aim of preventing such color unevenness, and consists of laminating a transparent substrate having an electrochromic material layer formed on a transparent electrode and a transparent substrate having a counter electrode formed thereon via an electrolyte. In an EC light control body in which an insulating film is formed on at least one of the electrodes, the thickness of the insulating film is thicker near the electrode lead-out part and gradually becomes thinner as it moves away from the electrode lead-out part.
It is an EC dimmer.
本発明のEC調光体は、電極上に設けられた絶
縁膜の厚さを電極取り出し部付近で厚く、そこか
ら離れるに従い薄くして、EC層と対向電極間に
印加される電圧が常にほぼ一定に保たれるように
されるためEC層が均一に着消色し、色ムラを生
じなく見栄えが良い。このことは調光体としては
極めて重要なことであり、大面積の調光時におい
て部分的に色ムラを生じた場合、極めて見ずらい
ばかりでなく、電極取り出し部付近は急速に濃く
着色するため、電極取り出し部から離れた部分を
所定の濃度に着色するように電圧を印加した場
合、電極取り出し部付近では著しい濃い着色が生
じ、過着色によりEC層が劣化し、着色不良を生
じたり、変色を生じたりする恐れがある。 In the EC dimmer of the present invention, the thickness of the insulating film provided on the electrode is thick near the electrode extraction part and becomes thinner as it moves away from there, so that the voltage applied between the EC layer and the counter electrode is always approximately Since the color is kept constant, the EC layer is uniformly colored and faded, resulting in a good appearance with no color unevenness. This is extremely important for a light control body, and if color unevenness occurs locally when dimming a large area, not only will it be extremely difficult to see, but the area around the electrode extraction part will quickly become darkly colored. Therefore, when a voltage is applied to color the part away from the electrode extraction part to a predetermined density, extremely dark coloring occurs near the electrode extraction part, and the EC layer deteriorates due to excessive coloring, resulting in poor coloring. There is a risk of discoloration.
又、EC調光体の特長である着消色時以外には
電力を消費しなく、かつ液晶のように精密なギヤ
ツプ制御も要しなく、両方の電極が短絡しないよ
うにされていれば良いため、生産性が良いもので
もある。 In addition, it does not consume power except when coloring or decoloring, which is a feature of the EC dimming device, and it does not require precise gap control like liquid crystals, as long as both electrodes are not short-circuited. Therefore, it is also highly productive.

縁膜が厚くなるようにされている。 FIG. 1 is a sectional view of a basic example of the EC light control body of the present invention, in which a transparent substrate 4 has an EC layer 2 and an insulating film 3 formed on a transparent electrode 1, an insulating film 5, and a counter electrode 6. The transparent substrates 7 are opposed to each other so as to sandwich the electrolyte 8, and the periphery thereof is sealed with a sealing material 9. In the present invention, this insulating film is thick near the electrode lead-out part, and gradually becomes thinner as it moves away from there. Since the part is on the right side of the figure, the insulating film is thicker on the left side on the EC layer side, and thicker on the right side on the counter electrode side.

色性からみて好ましい。 This insulating film may be formed on the EC layer and the counter electrode as in the example shown in Figure 1, but it may also be provided only on either one or between the EC layer and the transparent electrode below. , it is sufficient that the EC layer is formed with a difference in film thickness so that the EC layer is colored and erased almost uniformly. In particular, it is preferable to form an insulating film at least on the EC layer side from the viewpoint of uniform coloring.
