We present UV properties and morphology of a large sample of bright galaxies at z = 5.6 7. The sample includes about 20 Lyman-alpha emitters (LAEs) and 10 Lyman-break galaxies (LBGs) that were spectroscopically confirmed in the Subaru Deep Field. Near-IR (or rest-frame UV) imaging data were obtained with HST WFC3. Here we focus on a few interesting aspects of these galaxies from our preliminary results. For example, many galaxies in this sample are likely merging/interacting systems with extended features or even resolved double cores, which is in contrary to the compact morphology of fainter LBG candidates at z > 6 found in the GOODS fields. These galaxies have steep UV slopes (< -2), consistent with previous studies. We did not find significant differences between LAEs and LBGs in the near-IR. We acknowledge NASA/STScI funding for HST programs 11149 and 12329.
