There have been conflicting reports on the electronic properties of twin domain boundaries (DBs) in MoSe2 monolayer, including quantum well states, charge density wave, and Tomonaga-Luttinger liquid (TLL). Here we employ low-temperature scanning tunneling spectroscopy to reveal both confinement effect signatures TLL one-dimensional DBs. The data do not support CDW at temperatures down ~5 K.
