Liquid crystal panel and liquid crystal display device

A liquid crystal panel comprising:

• a pair of substrates;
• and
• a liquid crystal layer sandwiched between the substrates,
• at least one of the substrates being provided with a first electrode and a second electrode, the liquid crystal layer being driven by a transverse electric field generated between the first and second electrodes,
• the liquid crystal layer containing liquid crystal molecules that align themselves perpendicularly to surfaces of the substrates when no electric field is applied,
• said liquid crystal panel having a rate of occupation by dead zones of 24% or higher and 35% or lower, the rate of occupation by dead zones being the proportion of portions whose respective tone-luminance ratios are 20% or lower to the total number of places into which a unit region has been divided equally along an X axis, obtained by normalizing the respective luminances of the places into which the unit region has been divided equally along the X axis.
