Polyimide film, laminate and surface material for display

A polyimide film comprising a polyimide containing a structure represented by the following general formula (1),

• wherein a total light transmittance measured in accordance with JIS K7361-1 is 85% or more;
• wherein a yellowness index calculated in accordance with JIS K7373-2006 is 30 or less;
• wherein a glass transition temperature is in a temperature range of from 150° C. to 400° C.;
• and
• wherein a tensile elastic modulus at 25° C. obtained by measuring a 15 mm×40 mm test piece at a tensile rate of 10 mm/min and a chuck distance of 20 mm in accordance with JIS K7127, is 1.8 GPa or more:
• where R1 is a tetravalent group that is a tetracarboxylic acid residue containing an aromatic ring or aliphatic ring;
• R2 is a divalent group that is a diamine residue;
• 10 mol % to 50 mol % of total R2s are diamine residues each containing one or two silicon atoms in a main chain thereof, and 50 mol % to 90 mol % of total R2s are diamine residues each containing no silicon atom and containing an aromatic ring or aliphatic ring;
• and n is a number of repeating units.
