Abstract： By means of conformal field theory, we have related the degrees of freedom of microstates to the entropy of three dimensional charged black hole as well as the entanglement entropy of three-dimensional De Sitter spacetime. We have shown that the degrees of freedom of the conformal theory responsible for the entropy represent states on the horizon and localized in physical spacetime.
