US  10,031,419 B2  53  54  nylene group, a 1,3-phenylene group, a 1,2-phenylene  group, and a 1,4-naphthylene group, and more preferably a  1,4-phenylene group.  Examples of the trivalent linking group which is repre› sented by L$_{4 }$ in a case where L$_{4 }$ forms a ring by bonding with  R$_{42 }$ favorably include a group formed by removing one  arbitrary hydrogen atom from the specific examples of the  divalent linking groups which are represented by L$_{4 }$ described above.  R$_{44 }$is the same as R$_{3 }$ in General Formula (3) above and  additionally, the preferable ranges thereof are also the same.  M$_{4 }$ is the same as M$_{3 }$ in General Formula (3) above and  additionally, the preferable ranges thereof are also the same.  Q$_{4 }$ is the same as Q$_{3 }$ in General Formula (3) above and  additionally, the preferable ranges thereof are also the same.  Examples of a ring which is formed by at least two of Q$_{4}$ ,  M$_{4}$ ,  and R$_{44 }$ being bonded with each other include a ring  which is formed by at least two of Q$_{3}$ ,  M$_{3}$ ,  and R$_{3 }$ being  bonded with each other and additionally, the preferable  ranges thereof are also the same.  Specific examples of the repeating unit which is repre› sented by General Formula ( 4) will be given below; how› ever, the present invention is not limited thereto.
