LG and Samsung offer near border-less TVs, but not at that size (i don't think). Sharp offers 70'', but their bezels are usually a little thicker than LG/Samsung. Mitsubishi makes DLP TVs that have small bezels but DLP tvs are a pain to maintain and have worse PQ.
No TV is bezel-less yet, and don't expect that feature anytime soon, as securing a panel without a bezel is probably pretty hard to engineer.
Look for the LG LM Series:
And Samsung 8000 series:
UN55ES8000 (up to 65 inches)
Looks like you may want to downsize or look into DLP/Plasmas.
