The value distribution of differential polynomials is studied. The results in this paper improve and generalize some previous theorems given by Yang Chungchun (On deficiencies of differential polynomials, Math. Z., 116(1970), 197-204), H. S. Gopalakrishna and S. S. Bhoosnurmath (On distribution of values of differential polynomials, Indian J. Pure Appl. Math., 17(1986), 367-372), I. Lahiri (A note on distribution of nonhomogeneous differential polynomials, Hokkaido Math.J., 31(2002), 453-458) and Yi Hongxun (On zeros of differential polynomials, Adv.in Math., 18(1989), 335-351) et al. Examples show that the results in this paper are sharp.
