Two IBM ThinkPad laptop screens viewed at an extreme angle.
LCD panels using TN tend to have a limited viewing angle relative to CRT and plasma displays. This reduces the number of people able to conveniently view the same image – laptop screens are a prime example. Usually when looking below the screen, it gets much darker; looking from above makes it look lighter. This distorts the colors and makes cheap LCD monitors unsuitable for work where color is important, such as in graphic design work, as the colors change when the eyes are moved slightly up or down, or when looking either at the top of the screen or at the bottom from a fixed position. Many displays based on thin film transistor variants such as IPS, MVA, or PVA, have much improved viewing angles; typically the color only becomes a little brighter when viewing at extreme angles, though much of the improvements on viewing angles has been done[citation needed] on lateral angles, not on vertical ones.

Consumer LCD monitors tend to be more fragile than their CRT counterparts. The screen may be especially vulnerable due to the lack of a thick glass shield as in CRT monitors, i.e., poking an LCD will cause a ring of color (popular with young kids) that can damage the screen. CRTs have thick glass protecting them from scratches or 'poke' damage.
