Description
しかしながら、特許文献2に記載されたグレージングユニットにおいて立体的な画像を表示するためには、少なくともガラス板/プラスチックフィルム/ガラス板/プラスチックフィルム/ガラス板と、少なくとも3枚のガラス板を要する複雑な構造が必要となる。その結果、グレージングユニット全体として厚く、重くならざるを得ず、利用可能な自動車や建築物等の用途が限られるという問題があった。
以下に本発明を詳述する。
図1において、発光ディスプレイ1は、発光層11と反射層12とを有する。このような発光ディスプレイ1に、光源2を用いて可視光及び発光層11に含まれる発光材料を励起する光を含む光を発光層11側から照射する(図1(a))。その結果、励起光線により発光材料から発光することによる画像111が表示されると同時に、反射層12により反射された可視光による画像121が表示される。画像111と画像121とは、各層の厚みにより僅かな距離のずれが生じることから、発光層11側の観察者3には、立体的な画像として認識される。
上記発光材料としては、具体的には例えば、高い発光性を発揮できることから、ハロゲン原子を含む配位子を有するランタノイド錯体が挙げられる。
ランタノイド錯体のなかでも、ハロゲン原子を含む配位子を有するランタノイド錯体は光線を照射することにより高い発光強度で発光する。上記ハロゲン原子を含む配位子を有するランタノイド錯体としては、ハロゲン原子を含む単座配位子を有するランタノイド錯体や、ハロゲン原子を含む二座配位子を有するランタノイド錯体、ハロゲン原子を含む三座配位子を有するランタノイド錯体、ハロゲン原子を含む四座配位子を有するランタノイド錯体、ハロゲン原子を含む五座配位子を有するランタノイド錯体、ハロゲン原子を含む六座配位子を有するランタノイド錯体等のハロゲン原子を含む多座配位子を有するランタノイド錯体が挙げられる。
しかも、上記ハロゲン原子を含む二座配位子を有するランタノイド錯体又はハロゲン原子を含む三座配位子を有するランタノイド錯体は、耐熱性にも優れる。発光ディスプレイを例えば合わせガラス用中間膜として自動車ルーフ用ガラスや建築物用窓ガラスに用いた場合、太陽光の赤外線が照射されることにより、高温環境下で使用されることが多い。このような高温環境下では発光材料が劣化して、特に合わせガラスの端部において発光材料が劣化してしまうことがある。発光材料として上記ハロゲン原子を含む二座配位子を有するランタノイド錯体又はハロゲン原子を含む三座配位子を有するランタノイド錯体を用いることにより、高温環境下においても劣化を防止することができる。
上記R2は、炭素数1以上のアルキレン基であることが好ましく、炭素数1~5のアルキレン基であることがより好ましく、炭素数1のメチレン基であることが最も好ましい。上記炭素数1以上のアルキレン基は水素原子の一部が、水素原子以外の原子及び官能基と置換されていても良い。
上記ハロゲン原子を含むアセチルアセトン骨格を有する二座配位子を有するランタノイド錯体は、例えば、Eu(TFA)3phen、Eu(TFA)3dpphen、Eu(HFA)3phen、[Eu(FPD)3]bpy、[Eu(TFA)3]tmphen、[Eu(FPD)3]phen等が挙げられる。これらのハロゲン原子を含むアセチルアセトン骨格を有する二座配位子を有するランタノイド錯体の構造を示す。
上記ハロゲン原子を含む配位子を有するランタノイド錯体が粒子状である場合、ランタノイド錯体の平均粒子径の好ましい下限は0.01μm、好ましい上限は10μmであり、より好ましい下限は0.03μm、より好ましい上限は1μmである。

なお、上記照射する光線の出力は、光源より10cm離れた位置に配置したレーザーパワーメーター(例えば、オフィールジャパン社製、「ビームトラックパワー測定センサー3A-QUAD」等)を用いた照射強度測定により測定することができる。
本発明の発光ディスプレイを含む合わせガラス用中間膜もまた、本発明の1つである。
また、本発明の合わせガラス用中間膜が、一対のガラス板の間に積層されている合わせガラスもまた、本発明の1つである。
上記合わせガラス用中間膜が多層構造である場合、本発明の発光ディスプレイは合わせガラス用中間膜の全面に配置されていてもよく、一部にのみ配置されていてもよく、合わせガラス用中間膜の厚み方向とは垂直の面方向の全面に配置されていてもよく、一部にのみ配置されていてもよい。本発明の発光ディスプレイが一部にのみ配置されている場合には、該一部を発光エリア、他の部分を非発光エリアとして、発光エリアにおいてのみ画像を表示できるようにすることができる。
例えば、上記合わせガラス用中間膜に遮音性能を付与するために、本発明の発光ディスプレイにおける熱可塑性樹脂100重量部に対する可塑剤の含有量(以下、含有量Xともいう。)を、他の層における熱可塑性樹脂100重量部に対する可塑剤の含有量(以下、含有量Yともいう。)よりも多くすることができる。この場合、上記含有量Xは上記含有量Yよりも5重量部以上多いことが好ましく、10重量部以上多いことがより好ましく、15重量部以上多いことが更に好ましい。合わせガラス用中間膜の耐貫通性がより一層高くなることから、上記含有量Xと上記含有量Yとの差は、50重量部以下であることが好ましく、40重量部以下であることがより好ましく、35重量部以下であることが更に好ましい。なお、上記含有量Xと上記含有量Yとの差は、(上記含有量Xと上記含有量Yとの差)=(上記含有量X-上記含有量Y)により算出される。

上記アセチル基量は、主鎖の全エチレン基量から、アセタール基が結合しているエチレン基量と、水酸基が結合しているエチレン基量とを差し引いた値を、主鎖の全エチレン基量で除算して求めたモル分率を百分率(モル%)で表した値である。

上記ガラス板として、2種類以上のガラス板を用いてもよい。例えば、透明フロート板ガラスと、グリーンガラスのような着色されたガラス板との間に、上記合わせガラス用中間膜を積層した合わせガラスが挙げられる。また、上記ガラス板として、2種以上の厚さの異なるガラス板を用いてもよい。
本発明の合わせガラス用中間膜又は本発明の合わせガラスと、発光材料の励起波長の光線を照射する光源と、反射層が反射する可視光線を照射する光源とを有する発光ディスプレイシステムもまた、本発明の1つである。
