摘要 |
An optical film contains an acrylic resin, in which at least one of a modulus of elongation on a machine direction and a modulus of elongation on a direction vertical to the machine direction is less than 2.3×109 N/m2 and an in-plane retardation value Re (nm) of the optical film represented by the following formula (i) satisfies the following formula (ia):;Re=(nx−ny)×d Formula (i);ΔRe=Re(10)−Re(0)≦10 Formula (ia);wherein, in the formulae, nx represents a refractive index in an in-plane slow axis direction of the optical film, ny represents a refractive index in an in-plane fast axis direction of the optical film, d represents a thickness (nm) of the optical film, Re(10) represents a retardation value when the optical film is stretched 10%, and Re(0) represents a retardation value in an unstretched state of the optical film. |

1. An optical film which comprises an acrylic resin, in which at least one of a modulus of elongation on a machine direction and a modulus of elongation on a direction vertical to the machine direction is less than 2.3×109 N/m2 and an in-plane retardation value Re (nm) of the optical film represented by the following formula (i) satisfies the following formula (ia):
Re=(nx−ny)×d Formula (i) ΔRe=Re(10)−Re(0)≦10 Formula (ia)wherein, in the formulae, nx represents a refractive index in an in-plane slow axis direction of the optical film, ny represents a refractive index in an in-plane fast axis direction of the optical film, d represents a thickness (nm) of the optical film, Re(10) represents a retardation value when the optical film is stretched 10%, and Re(0) represents a retardation value in an unstretched state of the optical film. |
