Title: OPTICAL FILM, FRONT PLATE OF IMAGE DISPLAY DEVICE COMPRISING SAME, IMAGE DISPLAY DEVICE, MIRROR WITH IMAGE DISPLAY FUNCTION, RESISTIVE TOUCH PANEL AND CAPACITIVE TOUCH PANEL
Abstract:
Provided are: an optical film which has both excellent keying durability and excellent production adequacy; a front plate of an image display device, which comprises this optical film; an image display device; a mirror with image display function; a resistive touch panel; and a capacitive touch panel. This optical film is obtained by sequentially laminating at least a first resin film, a bonding layer and a second resin film in this order; the tensile elastic moduli EA, EB and EC of the first resin film, the bonding layer and the second resin film satisfy formulae (1)-(5) described below; and the total thickness of the first resin film, the bonding layer and the second resin film is more than 100 μm. |EA - EB| ≤ 4.0 GPa (1) |EC - EB| ≤ 4.0 GPa (2) 2.0 GPa ≤ EA (3) 2.0 GPa ≤ EB (4) 2.0 GPa ≤ EC (5)
