Description
1つの実施形態においては、本発明の光学積層体は、前記薄ガラスと前記偏光板との間に、接着層をさらに備える。
1つの実施形態においては、上記接着層が、エポキシ系樹脂を含む。
1つの実施形態においては、上記保護フィルムの23℃における弾性率が、1.5GPa〜10GPaである。
1つの実施形態においては、本発明の光学積層体は、反射防止層をさらに備え、該反射防止層が、前記薄ガラスの前記偏光板とは反対側に配置される。
図1は、本発明のひとつの実施形態による光学積層体の概略断面図である。この光学積層体100は、厚みが100μm以下の薄ガラス10と、薄ガラス10の一方の側に配置される偏光板20とを備える。偏光板20は、偏光子21と、偏光子21の薄ガラス10側の面(すなわち、偏光子21と薄ガラス10との間)に配置される保護フィルム22とを含む。図示していないが、偏光板は、偏光子の薄ガラスとは反対側の面に配置される保護フィルムをさらに含んでいてもよい。好ましくは、薄ガラス10と偏光板20とは接着層30を介して積層される。
上記薄ガラスは、板状のものであれば、任意の適切なものが採用され得る。上記薄ガラスは、組成による分類によれば、例えば、ソーダ石灰ガラス、ホウ酸ガラス、アルミノ珪酸ガラス、石英ガラス等が挙げられる。また、アルカリ成分による分類によれば、無アルカリガラス、低アルカリガラスが挙げられる。上記ガラスのアルカリ金属成分(例えば、Na2O、K2O、Li2O)の含有量は、好ましくは15重量%以下であり、さらに好ましくは10重量%以下である。
上記偏光板は、偏光子を備える。上記偏光板は、好ましくは、偏光子の片側または両側に保護フィルムをさらに備える。1つの実施形態においては、上記偏光板は、偏光子の上記薄ガラス側(すなわち、偏光子と薄ガラスとの間)にのみ保護フィルムを備える。このような構成であれば、偏光子の耐久性に優れ、かつ、軽量な偏光板を得ることができる。また、保護フィルムにより、上記薄ガラスの保護効果を高めることができる。
上記偏光子の厚みは特に制限されず、目的に応じて適切な厚みが採用され得る。当該厚みは、代表的には、1μm〜80μm程度である。1つの実施形態においては、薄型の偏光子が用いられ、当該偏光子の厚みは、好ましくは20μm以下であり、より好ましくは15μm以下であり、さらに好ましくは10μm以下であり、特に好ましくは6μm以下である。このように薄い偏光子を用いることにより、薄型の光学積層体を得ることができる。
上記保護フィルムとしては、任意の適切な樹脂フィルムが採用され得る。保護フィルムの形成材料としては、例えば、ポリエチレンテレフタレート(PET)等のポリエステル系樹脂、トリアセチルセルロース(TAC)等のセルロース系樹脂、ノルボルネン系樹脂等のシクロオレフィン系樹脂、ポリエチレン、ポリプロピレン等のオレフィン系樹脂、(メタ)アクリル系樹脂等が挙げられる。なかでも好ましくは、ポリエチレンテレフタレート(PET)である。なお、「(メタ)アクリル系樹脂」とは、アクリル系樹脂および/またはメタクリル系樹脂をいう。
D−1.樹脂フィルム
本発明の光学積層体は、上記薄ガラスの偏光板とは反対側に、樹脂フィルムをさらに備えていてもよい。1つの実施形態においては、樹脂フィルムは、剥離可能に(例えば、任意の適切な粘着剤層を介して)積層され、本発明の光学積層体が使用に供されるまで薄ガラスを保護する。
本発明の光学積層体は、反射防止層をさらに備えていてもよい。反射防止層は、薄ガラスの偏光板とは反対側に配置され得る。
上記薄ガラスと偏光板とは、接着層を介して積層され得る。上記接着層を構成する材料としては、例えば、熱硬化性樹脂、活性エネルギー線硬化性樹脂等が挙げられる。このような樹脂の具体例としては、例えば、エポキシ系樹脂;エポキシ基、グリシジル基またはオキセタニル基等を有する環状エーテル類;シリコーン系樹脂;アクリル系樹脂およびこれらの混合物が挙げられる。なかでも好ましくは、エポキシ系樹脂を含む接着層が形成され得る。エポキシ系樹脂を含む接着層が形成されば、薄ガラスが破損し難く、耐衝撃性により優れる光学積層体を得ることができる。また、上記接着層に上記カップリング剤を添加してもよい。
本発明の光学積層体の製造方法としては、任意の適切な方法が採用され得る。該製造方法は、例えば、(1)薄ガラス一方の面において、接着剤組成物を介して薄ガラスと偏光板とを貼り合わせる貼着工程と、(2)接着剤組成物を硬化させて、接着層を形成する硬化工程とを含む。
