The present invention relates to a polyimide precursor including a repeating unit expressed by chemical formula (1), wherein the polyimide precursor is characterized in that A includes at least two repeating units expressed by chemical formula (1) that is a group expressed by any of chemical formulas (2-1), (2-2), (3) or (4), and a polyimide obtained from the polyimide precursor has a linear thermal expansion coefficient of 50 ppm/K or less at 50 to 200 DEG C, and a transmittance of at least 75% at a wavelength of 400 nm and a polyimide film thickness of 10 mum (in the formula, A represents a bivalent group excluding an amino group from an aromatic diamine or an aliphatic diamine; and X1 and X2 individually represent hydrogen, a C1-6 alkyl group, or a C3-9 alkylsilyl group).
