  We present self-consistent models for the radiative transfer in
Shakura-Sunyaev accretion discs in bright low-mass X-ray binaries (LMXB). Our
calculations include the full effects of incoherent Compton scattering and the
vertical temperature structure within the disc, as well as the effects of
Doppler blurring and gravitational redshift. We find that the observed X-ray
spectra are well fit by exponentially cutoff power-law models. The difference
between the observed total spectrum and our calculated disc spectrum should
reveal the spectrum of the disc/neutron star boundary layer and other emitting
regions considered to be present in LMXB.
