A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display (LCD) that uses thin-film transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active-matrix LCD, in contrast to passive-matrix LCDs or simple, direct-driven LCDs with a few segments. These are more of the newer style ones.
Advantages and disadvantages
Thinner and lighter then CRT monitors making them suitable for portable
products.
The back lighting does not evenly light the screen causing dark and light patches.
Narrow viewing angle - Picture quality changes as the viewer moves
around.

A cathode ray tube (CRT) monitor is an analog computer display or television set with a large, deep casing. This type of monitor uses streams of electrons that activate dots or pixels on the screen to create a full image. These are the more older style ones.
Advantages and disadvantage
Cheap to buy.
Produces good colors.
Large footprint so takes up lots of desktop space.
Very heavy compared to other monitor types.
Screen is generally convex and this makes output at the edges slightly distorted.
