What you describe is the type of anti-reflection (AR) and anti-glare (AG)
coating that is applied to the front polariser. AFAIK no LCD has an extra
sheet of glass infront of the LCD, all have the front polariser exposed to
touch if you want to.
In the past, all LCDs were designed with AR and AG coatings to stop specular
reflections that bugged CRTs so badly. But a few years ago some marketing
guru realised that if you took off the AR coating some people actually
thought it looked "better" because it looked shinier. It didn't matter that
you would end up seeing a direct reflection of your window or lights in the
TV at home, it looked shinier in the shop so it sold more units.
AR and AG coatings don't affect the contrast ratio that you see quoted in
the specs (these must all be measured in a totally black room with no
ambient light), but in real life situations it will be different.
Basically, if you are going to be watching in a dark room with no direct
light sources it won't make any difference. But if you are going to be
watching in a bright room with a window and several lights, get the AGAR
coating (the non-shiny one), it will look much better than a CRT under
bright lights.
FWIW I took my LCD to my mum's house once and put it next to her CRT. When
there was direct sunlight shining on both of them the CRT was all but
unreadable, but with the LCD you could hardly notice which part was in sun
and which part wasn't, the "real life" contrast was definitely way better on
the LCD, even if the specs disagreed.
