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.
