When was the LCD TV invented?
In 1962, RCA researcher Richard Williams generated stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what is now called "Williams domains" inside the liquid crystal.

I don't know exactly who or when exactly they invented it. But I know that LCD screens have been around for quite a while. Remember all those little hand-held pocket TVs? they all have LCD screens, and they have been around for quite a while, way before regular home LCD TVs become popular with the advent of HDTV.
