To reduce viewing angle dependence of characteristics in a normally black liquid crystal display. Each pixel 10 has a first sub-pixel 10a and a second sub-pixel 10b which can apply mutually different voltages to their respective liquid crystal layers. Relationships V12 (gk)0 volts and V12 (gk)V12 (gk+1) are satisfied at least in a range 0 gkn-1 if it is assumed that V12=V1-V2, where V12 is the difference between root-mean-square voltage V1 applied to the liquid crystal layer of the first sub-pixel 10a and root-mean-square voltage V2 applied to the liquid crystal layer of the second sub-pixel 10b.
