Abstract: 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 10 mol % to 35 mol % of 10 mol % to 35 mol % of 10 mol % to 50 mol % of and 10 mol % to 40 mol % of AR1 is wherein each of ring R and ring S is independently a C3-20 ring, ring R and ring S share a carbon atom, and each of K1 and K2 is independently a C5-20 conjugated system. Each of AR2, AR3, AR4, and AR5 is independently AR6 or AR6—Z—AR7.
