People clad in colourful clothes burst crackers and exchanged greetings and sweets with friends and neighbours.
Cinema remains a chief attraction during the festive holidays but this Deepavali, only two Tamil films starring big stars have hit the screens.
'Kodi', starring Dhanush in a dual role and Karthi's 'Kashmora,' both of which have seen heightened expectations among film buffs.
'Kadalai' and 'Thiraikku Varatha Kathai' were also released across screens in the state.
Tamil Nadu Governor Ch Vidyasagar Rao, state BJP leaders Pon Radhakrishnan and Tamilisai Sounderrajan and TNCC President Su Thirunavukkarasar among others have extended Deepavali greetings to the people.
