The display does not flicker per-se*. Transflexive, non-backlit LCD's certainly have none. But most LCD's are backlit, and that lighting does flicker.

(*some early and even now badly-made LCD's can have issues with perception of the update, even at an unconscious level, but that's not very common)

Or rather, the commonly used CCFL's flicker, the LCD's which have begun reaching the market in the last two years don't, but they suffer their own issues, especially in LED aging and changing colour points, several technical issues relating to voltage and heat and currently high pricing.
