Representation theory of algebras is a new branch of algebra which began at the seventies of the last century. Tilting theory is an important tool to study representation theory of algebras. The main purpose of this paper is to study structural characteristics of the tilting module over path algebras of type D_n in theirs AR-quivers. It takes advantages of AR-quiver analysis. The paper shows that if T is a tilting A-module over a path algebra of type D_n, then there are at least three points corresponding indecomposable direct summands of T in the edges of Γ_A.
