The paper is concerned about a sharp form of Anisotropic Moser-Trudinger inequality which involves L n norm. Let λ 1 (Ω)= inf u∈ W 0 1, n (Ω), u≢ 0|| F (∇ u)|| L n (Ω) n/|| u|| L n (Ω) n be the first eigenvalue associated with n-Finsler-Laplacian. Using blow-up analysis, we obtain that sup u∈ W 0 1, n (Ω),|| F (∇ u)|| L n (Ω)= 1∫ Ω e λ n (1+ α|| u|| L n (Ω) n) 1 n− 1| u| n n− 1 d x is finite for any 0≤ α< λ 1 (Ω), and the supremum is infinite for any α≥ λ 1 (Ω), where λ n= n n n− 1 κ n 1 n− 1 (κ n is the volume of the unit wulff ball) and the function F is positive, convex and homogeneous of degree 1, and its polar F o represents a Finsler metric on R n. Furthermore, the supremum is attained for any 0≤ α< λ 1 (Ω).
