Abstract: In order to reveal the stellar mass distribution of z ∼ 3 galaxies, we are conducting deep imaging observations of U-dropout Lyman-break galaxies (LBGs) with Adaptive Optics (AO) systems in K-band, which corresponds to rest-frame V -band of z ∼ 3 galaxies. The results of the Subaru intensive-program observations with AO36/NGS/IRCS indicate that: 1) the K-band peaks of some of the LBGs brighter than K = 22.0 mag show significant offset from those in the optical images; 2) the z ∼ 3 M*V LBGs and serendipitously observed distant red galaxies (DRGs) have flat profiles similar to disk galaxies in the local universe (i.e., Sérsic with n < 2); and 3) the surface stellar mass densities of the M*V LBGs are 3-6 times larger than those of disk galaxies at z = 0 − 1.
