Description
図1に示すように、光学補償板10は、基板11上に、位相差補償層12、中間層13、反射防止層14をこの順に積層して形成される。
第1実施形態の光学補償板10では、中間層13を、位相差補償層12または反射防止層14のいずれかと同じ材料からなる一つの膜で形成しているが、図2に示す光学補償板20のように、中間層21を第1薄膜21aと第2薄膜21bの2つの薄膜で形成することが好ましい。この場合、位相差補償層12に接する第1薄膜21aは、位相差補償層12と同じ材料からなる稠密膜にし、反射防止層14に接する第2薄膜21bは、反射防止層14と同じ材料からなる稠密膜にする。
第2実施形態の光学補償板20では、中間層21を第1薄膜21aと第2薄膜21bの二膜構成にしているが、中間層21を三膜構成の誘電体多層膜層(第1誘電体多層膜層)で構成しても良い。この場合、図3に示す光学補償板26の中間層27のように、第1薄膜21aと第2薄膜21bの間に第3薄膜28を加える。そして、この第3薄膜28は、第1薄膜21aと第2薄膜21bの中間の屈折率になるように材料や膜数を決定し、第1薄膜21aと第2薄膜21bの屈折率差を緩和することが好ましい。こうすると、中間層27は、位相差補償層12との密着性及び反射防止膜層14との密着性を良好に維持しつつ、光学補償板20の第1薄膜21aと第2薄膜21bの界面における反射も抑制することができる。中間層21を四膜以上で構成する場合には、第1薄膜21aと第2薄膜21bの間に設ける薄膜数を増やせば良い。
第1〜第3実施形態の各光学補償板10,20,26,30,33では、網目状多孔構造の反射防止層14が表面に露呈されているが、図6に示す光学補償板40のように、反射防止層14に耐油性コーティング41を施しておくことが好ましい。耐油性コーティング41は、例えば、フッ化マグネシウム(MgF2)で形成される。また、耐油性コーティング41は、フッ素樹脂でも良い。
