The £3,000 TV, the latest in the Japanese firm's Bravia range, is just 9.9mm thick. That is 60 TIMES slimmer than a typical set from the 1950s.
It is so thin because tiny LED lights usually illuminating the flat screen from behind have been placed round the sides.
Spokesman Christian Brown said: "Sony is continuously striving to lead the way with advanced innovations in TV technology and cutting edge design. We're excited to see our customers' reactions."
THE 1969 moon landing has been voted the best "World First" captured on TV, according to a Sony poll to promote its new tellies. Barack Obama's inauguration was second and the assassination of John F Kennedy third.
