A liquid crystal alignment solution is provided. The liquid crystal alignment solution includes a first polyimide-polyamide acid and a second polyimide-polyamide acid. The first polyimide-polyamide acid is represented by formula (A), and the second polyimide-polyamide acid is represented by formula (B), in which T1, T2, T3 and T4 are each independently a tetravalent residue of a tetracarboxylic acid dianhydride; D1, D2, D3 and D4 are each independently a divalent residue of a diamine; and m, n, p and q are each independently an positive integer, wherein m/(m+n)<=0.5 and p/(p+q)>=0.5.
