THIN-FILM TRANSISTOR SUBSTRATE, LIQUID CRYSTAL DISPLAY ELEMENT, ORGANIC EL ELEMENT, RADIOSENSITIVE RESIN COMPOSITION, AND MANUFACTURING METHOD OF THIN-FILM TRANSISTOR SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide: a thin-film transistor substrate having an interlayer insulation film which is hard to cause the whitening in a high-temperature treatment and in which the occurrence of outgassing is suppressed; a liquid crystal display element and an organic EL element, each including the thin-film transistor substrate; a radiosensitive resin composition which enables the suitable formation of the interlayer insulation film as described above; and a method for manufacturing the thin-film transistor substrate.;SOLUTION: A thin-film transistor substrate comprises: a substrate; a thin-film transistor disposed on the substrate; and an interlayer insulation film disposed on the thin-film transistor. The interlayer insulation film includes a polymer having a structure represented by the formula (1) below. (In the formula (1), R¹ represents a divalent coupling group including a heteroatom, R² represents a monovalent organic group including an aromatic ring, and * represents a coupling portion.);SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
