We present the atomically resolved room temperature scanning-tunneling microscopy study of bias dependent images of charge density waves (CDWs) in 1T-TaSe2. With the help of angle-resolved photoemission of the CDW-split Ta d(z)(2) band in 1T-TaSe2, we determine the electronic location of Ta d(z)(2) subbands on inequivalent atoms of the reconstructed Ta plane. We thus demonstrate the atomic origin of the CDW-formation related effects observed in the band structure of this material.
