We present the results of deep K'- and J-band imaging of the field of a proto-cluster region near the radio galaxy 53W002 at z=2.390 with the Subaru Telescope. The data were analyzed together with deep optical and near-infrared (NIR) images taken with the Hubble Space Telescope to investigate the properties of ten optically compact emission-line galaxies and candidates. Excluding the three objects which may contain active galactic nuclei, many are faint or undetected at K'(λrest ≈ 6000 Å), and are therefore revealed to be intrinsically small starbursting objects. On the other hand, we detect few objects with colors and magnitudes expected for quiescent massive galaxies at z=2.4 in the field.
