<p>[Problem] To provide a resin composition for display substrates which is capable of forming a useful polyimide film with an appropriate linear expansion coefficient and an appropriate flexibility. [Solution] This resin composition for display substrates contains a polyamic acid which includes a structural unit represented by formula (1) and a structural unit represented by formula (3), or a polyimide which includes a structural unit represented by formula (2) and a structural unit represented by formula (4). [In formulae 1 through 4, X1 represents a tetravalent organic group having an aromatic group and two or more carbonyl groups, Y1 represents a divalent organic group, Y2 represents a divalent organic group having an alkali-soluble group, and n and m represent natural numbers.]</p> |
