| description | To provide: polyamic acid soluble in a mild solvent; and a thermosetting composition, a cured film and a liquid crystal display element each using the polyamic acid. To provide a liquid crystal made of the polyamic acid of the present invention and to provide a thermosetting composition that has an orientation ability for a polymerizable liquid crystal and a flattening ability for a substrate. To provide a cured film made of the thermosetting composition of the present invention and having a high transmittance and a high voltage retention. And to provide an electronic component such as a liquid crystal display element and a solid-state imaging device each having the cured film.SOLUTION: Polyamic acid is provided which is obtained by reacting an aliphatic tetracarboxylic dianhydride of specific structure and a raw material including aliphatic diamine having specific structure. A thermosetting composition is provided which uses the polyamic acid.SELECTED DRAWING: None
【課題】穏和な溶剤に可溶なポリアミド酸およびそれを用いた熱硬化性組成物、硬化膜および液晶表示素子を提供すること。また、本発明のポリアミド酸を用いた液晶および重合性液晶に対する配向能力と下地に対する平坦化能力を有する熱硬化性組成物を提供すること。さらに、本発明の熱硬化性組成物からなる高透過率、高電圧保持率を与える硬化膜を提供すること。該硬化膜を有する液晶表示素子や固体撮像素子などの電子部品を提供すること。【解決手段】特定構造を有する脂肪族テトラカルボン酸二無水物と特定構造を有する脂肪族ジアミンを含む原料を反応させて得られるポリアミド酸。およびこのポリアミド酸を用いた熱硬化性組成物。【選択図】 なし |
