Hi, Abou, ! صباح الخير
There are lot of different materials used for LCD's, read here: http://www.madehow.com/Volume-1/Liquid-Crystal-Display-LCD.html (text slighty obsolete). Every year thousands of new materials for LCD's are elaborated, some of them come to the production.
The producer of TV's frequently is not producer of the screen itself, and details about technology are not shared.
The life of LCD's is declared as tens of years, but there is no "hard" proof, because this technology is relatively young (in except of b/w screens in calculators and watches). You can expect the life of LCD as much longer than the life of TV receiver (or even a transmission standard).
Good maintenance? It's simple: no wet washing (لا ماء), no force (لا المطرقة) & no scratching (لا الرمال)! Some cleaners are commonly accessible (read recomendations of TV' producers).

thank you my freind and thx for arabic lang .. how did you know the lang ?

كنت أعمل السنوات القليلة في ليبيا

And you from where ?

I'm polish, but I've spend many years in different countries and therefore I know many languages. Now I'm old and retired ...

you are lucky man , i have 35 years and still stuck here .

You're a lucky man, you're young!
When I was in your age (40 years ago) I was 'stuck' much more!
There was no Internet and I didn't know any "international" language (in except of russian ...).

I'm sorry can i send pvt msg for you to tell about your story ?

OK!

The molecular structure of a liquid crystal matches that of a solid, but its molecules behave like a liquid. As a result, liquid crystals are at the heart of an LCD television. With backlighting (the crystals emit no light of their own), the millions of crystals in an LCD television provide a sharp, high-resolution color picture for their owner.
