| abstract |
The purpose of the present invention is to provide: a film having high resistance, high bending strength (tensile elongation), small retardation in the thickness direction, a low linear expansion coefficient, and high transparency; and a polyamic acid or varnish for obtaining the film. The film satisfies all of requirements (i)-(vi) below. (i) The average value of the linear expansion coefficient in the range of 100-200°C is 35 ppm/K or less. (ii) The absolute value of the retardation in the thickness direction is 200 nm or less per 10 μm of thickness. (iii) The glass transition temperature is 340°C or higher. (iv) The total light transmittance is at least 85%. (v) The b* value in the L*a*b* color system is 5 or less. (vi) The tensile elongation is at least 10%. |
