Claim 0:
1. A liquid crystal polymer film, wherein a material of the liquid crystal polymer film is a liquid crystal polymer resin comprising a structural unit represented by Formula (1):

-L1-Ar-L2-  (1);

wherein -L1- and -L2- are respectively —O— or —CO—; —Ar— is an arylene group;
wherein Formula (1) comprises structural units as follows:, wherein based on a total molar number of the structural unit represented by Formula (1), a molar number of the structural unit represented by Formula (I) is in the range from 15 mole % to 40 mole %, and a sum of molar numbers of the structural units represented by Formulae (I) and (II) is in the range from 80 mole % to 100 mole %;
wherein the liquid crystal polymer film has a thickness in the unit of μm and a transmittance (TT %), wherein when values of the thickness and the transmittance are put into Formula (III): log(1/TT %)/(thickness)0.5, an obtained value is larger than 0.055 and smaller than 0.090;
wherein the liquid crystal polymer film comprises a first surface and a second surface opposite each other, and a Kurtosis (Sku) of the first surface is equal to or larger than 1 and smaller than or equal to 300.
