An operator (Formula presented.) is called the dilation of a truncated Toeplitz operator if for two symbols (Formula presented.) and an inner function u, (Formula presented.) for (Formula presented.) where (Formula presented.) denotes the orthogonal projection of (Formula presented.) onto the model space (Formula presented.) and (Formula presented.) In this paper, we study properties of the dilation of truncated Toeplitz operators on (Formula presented.). In particular, we provide conditions for the dilation of truncated Toeplitz operators to be normal. As some applications, we give several examples of such operators.
