TV display used to be of a Cathod Ray Picture tube. As the technology changed the display is changed to Liquid Crystal Display (LCD)
Some details as given at: http://en.wikipedia.org/wiki/Television
CRT: The most common displays are direct-view CRTs for up to 40 in (100 cm) (in 4:3) and 46 in (115 cm) (in 16:9) diagonally. These are still the least expensive, and are a refined technology that can still provide the best overall picture quality. As they do not have a fixed native resolution, in some cases they are also capable of displaying sources with a variety of different resolutions at the best possible image quality. The frame rate or refresh rate of a typical NTSC format CRT TV is 60 Hz, and for the PAL format, it is 50 Hz. A typical NTSC broadcast signal's visible portion has an equivalent resolution of about 640x480 pixels. It actually could be slightly higher than that, but the Vertical Blanking Interval, or VBI, allows other signals to be carried along with the broadcast.
Rear projection: Most very large screen TVs (up to over 100 inch (254 cm)) use projection technology. Three types of projection systems are used in projection TVs: CRT-based, LCD-based, and DLP (reflective micromirror chip) -based. Projection television has been commercially available since the 1970s, but at that time could not match the image sharpness of the CRT; current models are vastly improved, and offer a cost-effective large-screen display. A variation is a video projector, using similar technology, which projects onto a screen.
Flat panel LCD or plasma: Modern advances have brought flat panels to TV that use active matrix LCD or plasma display technology. Flat panel LCDs and plasma displays are as little as 1 inch thick and can be hung on a wall like a picture or put over a pedestal. Some models can also be used as computer monitors.

It means liquid crystal display. Normal Tv used cathode ray osciloscope to display image(cro) but in Lcd, there is a special liquid which under chemical reaction or under the action of electricity, behaves in way that gives different colour tones according to the required display type.

Full form of LCD:Liquid Crystal Display.
Color:LCD TVs are renowned for a sharp picture and vibrant color
Brightness:LCD TVs are said to do slightly better in bright-light conditions
Black Levels:LCD TV will produce a very dark charcoal gray.
Contrast Level:LCD TV have a great contrast level.
Cost:LCD TV cost are rapidly increasing.
LCD TVs are sometimes susceptible to a delay that causes the outline of figures or objects to appear jagged.

LCD stands for "Liquid Crystal Display" - it's the same type of screen found on most modern laptops.

Liquid crystal diode
Short for liquid crystal display, a type of display used in digital watches and many portable computers. LCD displays utilize two sheets of polarizing material with a liquid crystal solution
