Abstract:
(EN) Provided are: an optical film which is sufficiently suppressed in interference irregularity, while having excellent keying durability and the like; and a front panel of an image display device, an image display device, a mirror with image display function, a resistive touch panel and a capacitive touch panel, each of which comprises this optical film. This optical film comprises at least a first resin film, an adhesive layer that is arranged on one surface of the first resin film, and a second resin film that is arranged on the adhesive layer. The refractive indexes nA, nB and nC and the tensile elastic moduli EA, EB and EC of the first resin film, the adhesive layer and the second resin film satisfy the formulae below; and the total thickness of the first resin film, the adhesive layer and the second resin film is more than 100 μm. |nA - nB| ≤ 0.03 formula (1) |nC - nB| ≤ 0.03 formula (2) |EA - EB| ≤ 4.0 GPa formula (3) |EC - EB| ≤ 4.0 GPa formula (4) 2.0 GPa ≤ EA formula (5) 2.0 GPa ≤ EB formula (6) 2.0 GPa ≤ EC formula (7)
(FR) L'invention concerne : un film optique qui est suffisamment supprimé dans une irrégularité d'interférence, tout en ayant une excellente durabilité de codage et similaire; et un panneau avant d'un dispositif d'affichage d'image, un dispositif d'affichage d'image, un miroir ayant une fonction d'affichage d'image, un panneau tactile résistif et un panneau tactile capacitif, dont chacun comprend ce film optique. Ce film optique comprend au moins un premier film de résine, une couche adhésive qui est disposée sur une surface du premier film de résine, et un second film de résine qui est disposé sur la couche adhésive. Les indices de réfraction nA, nB et nC et les modules d'élasticité de traction EA, EB et EC du premier film de résine, de la couche adhésive et du second film de résine satisfont les formules ci-dessous; et l'épaisseur totale du premier film de résine, de la couche adhésive et du second film de résine est supérieure à 100 µm.|nA-nB|≤ 0,03 formule (1)|nC-nB|≤ 0,03 formule (2)|EA-EB|≤ 4,0 GPa formule (3)|EC-EB|≤ 4,0 GPa formule (4) 2,0 GPa ≤ EA formule (5) 2,0 GPa ≤ EB formule (6) 2,0 GPa ≤ EC formule (7)
(JA) 干渉ムラが十分に抑制され、打鍵耐久性等に優れる光学フィルム並びにこれを有する画像表示装置の前面板、画像表示装置、画像表示機能付きミラ-、抵抗膜式タッチパネル及び静電容量式タッチパネルを提供する。光学フィルムは、第一の樹脂フィルムと、この第一の樹脂フィルムの片面に配された接着層と、この接着層上に配された第二の樹脂フィルムとを少なくとも有し、上記の第一の樹脂フィルム、接着層及び第二の樹脂フィルムの屈折率nA、nB及びnC並びに引張弾性率EA、EB及びECが下記式を満たし、上記の第一の樹脂フィルム、接着層及び第二の樹脂フィルムの合計厚みが100μmより大きい。 式(1)|nA-nB|≦0.03 式(2) |nC-nB|≦0.03式(3)|EA-EB|≦4.0GPa 式(4)|EC-EB|≦4.0GPa 式(5)2.0GPa≦EA 式(6)2.0GPa≦EB 式(7)2.0GPa≦EC
