We investigate a particular aspect of the asymptotic expansion of the Wrightfunction ${}_1\Psi_1(z)$ for large $|z|$. The form of the exponentially smallexpansion associated with this function on certain rays in the $z$-plane (knownas Stokes lines) is discussed. The main thrust of the paper is concerned withthe expansion in the particular case when the Stokes line coincides with thenegative real axis $\arg\,z=\pi$. Some numerical examples which confirm theaccuracy of the expansion are given.
