A liquid crystal polymer includes at least one repeating unit having a spiro structure, and the repeating unit occupies 1 mol% to 20 mol% of the liquid crystal polymer. The liquid crystal polymer is composed of the following repeating units: 1 mol% to 20 mol% of (1) ；10 mol% to 35 mol% of (2) , 10 mol% to 35 mol% of (3) , 10 mol% to 50 mol% of (4) , and 10 mol% to 40 mol% of (5) . AR 1 nis or , wherein each of ring R and ring S is independently C 3-20 nring, ring R and ring S share a carbon atom, and each of K 1 nand K 2 nis independently C 5-20 nconjugated system. Each of AR 2 n, AR 3 n, AR 4 n, and AR 5 nis independently AR 6 nor AR 6 n-Z-AR 7 n. |
