Beschreibung
Zusammenfassung:	Provided is a polyimide precursor for a display substrate, said precursor having the structural units represented by general formula (1) and including a group containing an acidic group as at least some of a group represented by X1 in general formula (1), a group represented by Y1 in general formula (1), and a terminal group, the content of the acidic group being at least 15*10-3. (In general formula (1): X1 is a tetravalent aromatic group or an aliphatic group; Y1 is a divalent aromatic group; R1 and R2 are independently of each other a hydrogen atom, a C1-6 alkyl group, or a C3-9 alkylsilyl group.).
