摘要： The present invention provides a liquid crystal display panel that suppresses the temperature dependence of transmittance-gradation characteristics and thus overcomes problems in which significant changes in transmittance-gradation characteristics are caused by the effects of environmental temperature and a light source to lead to the degradation of display performance, and a liquid crystal display device including the liquid crystal display panel. The liquid crystal display panel of the present invention includes a liquid crystal medium containing a plurality of liquid crystal compounds each having a negative dielectric constant anisotropy, the liquid crystal medium being held between a first substrate and a second substrate that are located opposite each other, and a side of each of the substrates in contact with the liquid crystal medium having vertical alignment properties for the liquid crystal compounds. The liquid crystal medium in the liquid crystal display panel contains a liquid crystal composition (1) or a liquid crystal composition (2) having a specific composition. In the liquid crystal display panel, Δγ which pertains to a transmittance-gradation characteristic curve coefficient and which is calculated from specific expressions is 0.2 or less.
