ABSTRACT:
To reduce viewing angle dependence of γ characteristics in a normally black liquid crystal display.Each pixel10has a first sub-pixel10aand a second sub-pixel10bwhich can apply mutually different voltages to their respective liquid crystal layers. Relationships ΔV12(gk)>0 volts and ΔV12(gk)≧ΔV12(gk+1) are satisfied at least in a range 0<gk≦n−1 if it is assumed that ΔV12=V1−V2,where ΔV12is the difference between root-mean-square voltage V1applied to the liquid crystal layer of the first sub-pixel10aand root-mean-square voltage V2applied to the liquid crystal layer of the second sub-pixel10b.
