Abstract
Description
〔電極が形成された第1基板〕
図1(a),(b)に示す第1の実施の形態と同様にして、PET(ポリエチレンテレフタレート)製の第1基板(厚み250μm)を準備し、その第1基板の片面に、電極基部と直線状の電極とからなる銀製の電極体を、グラビアオフセット印刷により形成した。その際、電極の幅と、対となる電極の間の隙間幅とを変えた4例(実施例1〜4)を作製した。それら電極の幅と隙間幅とを、後記の表1に示した。
上記電極が形成された第1基板について、電圧を印加させない状態で、平行光の透過率を測定し、その結果を後記の表1に示した。なお、その測定には、可視光線透過率測定器(佐藤商事社製、ガラス可視光線透過率測定器ティントメーターMJ−TM100)を用いた。
液晶層として、九州ナノテック光学社製のKN−221W(厚み10μm、高分子:多官能アクリレート)を準備した。
第2基板として、PET製のもの(厚み50μm)を準備した。
上記第1基板の電極体と、上記第2基板とが対面するようにして、それら第1基板と第2基板とで、上記液晶層を挟持した。これにより、図1(a),(b)に示す第1の実施の形態と同様の実施例1〜4の調光フィルムを作製した。
実施例1〜4の調光フィルムにおいて、印加する電圧を変化させ、平行光の透過率を測定した。この測定は、上記と同様の可視光線透過率測定器を用いた。そして、その結果を下記の表1に示した。
2A,2B 電極
3 液晶層
4 第2基板
Claims (3)
- 絶縁性および透光性を有する基板と、この基板の片面に形成された一対ないし複数対の線状の電極と、上記基板の上記電極形成面に積層された、高分子および液晶の複合材料からなる液晶層とを備えていることを特徴とする調光フィルム。
- 上記液晶層の、上記基板と反対側の面に、絶縁性および透光性を有する他の基板が積層されている請求項1記載の調光フィルム。
- 上記電極が、印刷方式で形成されている請求項1または2記載の調光フィルム。
