  In this paper, we study the uniform regularity and vanishing viscosity limit
for the compressible nematic liquid crystal flows in three dimensional bounded
domain. It is shown that there exists a unique strong solution for the
compressible nematic liquid crystal flows with boundary condition in a finite
time interval which is independent of the viscosity coefficient. The solutions
are uniform bounded in a conormal Sobolev space. Furthermore, we prove that the
density and velocity are uniform bounded in $W^{1, \infty}$, and the director
field is uniform bounded in $W^{3,\infty}$ respectively. Based on these uniform
estimates, one also obtains the convergence rate of the viscous solutions to
the inviscid ones with a rate of convergence.
