(A) a resin composition comprising a polysiloxane and (B) a solvent, wherein (A) the polysiloxane contains at least one partial structure represented by any one of the following general formulas (1) to (3), and the resin composition is applied and wherein the relationship between the film thickness X after drying at 100° C. for 3 minutes and the film thickness Y after heating at 230° C. for 5 minutes is (XY)/X≤0.05. This resin composition is excellent in the applicability|paintability with respect to the uneven|corrugated part, and has the outstanding planarization performance even in a thin film. (R 1 is a single bond or an alkyl group having 1 to 4 carbon atoms, R 2 is an alkyl group having 1 to 4 carbon atoms, and R 3 is an organic group.) |
