(57) [Summary] [Structure] A coating composition containing a siloxane polymer obtained by hydrolyzing and condensing a hydrolyzable group-containing silane mixture and a film curing agent, wherein the silane mixture is a bifunctional silane. A coating composition comprising a mixture containing 1 to 20 mol of a trifunctional silane with respect to 1 mol. The coating composition of the present invention has excellent crack resistance and can be suitably used as a buffer coat of a semiconductor device requiring a thick film, a flattening agent, or a protective film of a liquid crystal display. |
