Abstract:
Disclosed is a liquid crystal display device, wherein u′on axis and v′on axis, u′max and v′max, and u′min and v′min satisfy following expressions (1), (2) and (3): u ave ′ = ( u max ′ - u min ′ 2 ) , v ave ′ = ( v max ′ - v min ′ 2 ) ( 1 ) Δ u ′ v ave - on axis ′ = ( u ave ′ - u on axis ′ ) 2 + ( v ave ′ - v on axis ′ ) 2 ≦ 0.04 ( 2 ) 0.35 ≦ v on axis ′ ≦ 0.55 ( 3 ) wherein u′on axis and v′on axis are hues in a black state observed in a front direction; u′max and v′max are maximum values of u′ and v′ in a black state among values observed in directions with an azimuth angle ranging from 0° to 360° and a polar angle of 60°; and u′min and v′min are minimum values of u′ and v′ in a black state among values observed in directions with an azimuth angle ranging from 0° to 360° and a polar angle of 60°.
