We present Keck spectroscopic observations of z>6 Lyman-break galaxy (LBG) candidates in the Subaru Deep Field (SDF). The candidates were selected as i'-dropout objects down to z'=27 AB magnitudes from an ultra-deep SDF z'-band image. With the Keck spectroscopy we identified 19 LBGs with prominent Ly_alpha emission lines at 6 100 A. This well-defined spectroscopic sample spans a UV-continuum luminosity range of -21.8 ~6.2 after we correct for sample incompleteness. We find that our measurement… Expand
