The present invention provides a substrate tray for depositing a thin film and a thin film depositing apparatus including the same. Wherein, the substrate tray includes a tray body which includes an opening part which exposes the deposition surface of a substrate in the center thereof, a support plate which divides the opening part into an exposing area and a blocking area and supports the substrate loaded on the tray body, a cover plate which covers the support plate by interposing the substrate, and a means for closely bonding the substrate to the support plate and the cover plate.
