We consider a model of liquid crystals, based on a nonlinear hyperbolic system of differential equations, that represents an inviscid version of the model proposed by Qian and Sheng. A new concept of dissipative solution is proposed, for which a global-in-time existence theorem is shown. The dissipative solutions enjoy the following properties: (i) they exist globally in time for any finite energy initial data, (ii) dissipative solutions enjoying certain smoothness are classical solutions, (iii) a dissipative solution coincides with a strong solution originating from the same initial data as long as the latter exists.
