Provided is a semiconductor element having a semiconductor layer and an insulating layer adjacent to the semiconductor layer, in which the insulating layer is formed of a crosslinked product of a polymer compound having a repeating unit (IA) represented by the following General Formula (IA) and a repeating unit (IB) represented by the following General Formula (IB). n n n n n n n n n n In General Formula (IA), R 1a represents a hydrogen atom, a halogen atom, or an alkyl group. L 1a and L 2a each independently represent a single bond or a linking group. X represents a crosslinkable group. m2a represents an integer of 1 to 5, and in a case where m2a is 2 or more, m2a number of X's may be the same or different from each other, m1a represents an integer of 1 to 5, and in a case where m1a is 2 or more, m1a number of (-L 2a -(X) m2a )'s may be the same or different from each other. In General Formula (IB), R 1b represents a hydrogen atom, a halogen atom, or an alkyl group. L 1b represents a single bond or a linking group, and Ar 1b represents an aromatic ring, m1b represents an integer of 1 to 5. |
