The screen on this particular model has a matte finish. I don't know which models have a matte screen or a glossy screen. I would suggest going on the Samsung site and checking the specs there; if you can't discern the information from the Amazon description.
It's actually a semi gloss. If it were a true matte screen it would have no reflection at all. This TV has a slight reflection, not enough to notice when the set is on but when off, you can clearly see reflection though not as much as a true gloss screen.
