    They are non-toxic compared with CFLs (non mercury).

    They withstand shock a LOT better than CFLs.

    They don't require hi voltage supplies to drive them. (less likelihood of power-supply / modulation noise heard)

    Less flicker seen, and better performance in cold temperatures.

    Power consumption getting better and better - which equates to longer runtimes over CFLs.

    Lower heat generation than a CFL.

    Ability to space / locate as many sources as required for the display - instead of being limited by shape / length of a CFL tube.

    Edit: oops CFL = Compact Fluorescent Lamp.

    Old LCDs with CCFL backlights would take 20-30 minutes to fully 'warmup'. LCDs do not have this behavior, and are much brighter from the get-go. They also use less battery, have a longer lifetime, strain my eyes ;), and are more environmentally friendly
