Claim:
A liquid crystal display apparatus comprising: a liquid crystal cell of a mono domain vertical alignment type; and a driver apparatus which applies a multiplex driving waveform to said liquid crystal cell, wherein said liquid crystal cell of the mono domain vertical alignment type comprises: first and second substrates disposed facing each other; a liquid crystal layer sandwiched between said first and second substrates; and a first vertical alignment film formed above said first substrate on a side of said liquid crystal layer, and a second vertical alignment film formed below said second substrate on a side of said liquid crystal layer, wherein at least one of said first and second vertical alignment films has an aligning texture which gives liquid crystal molecules in said liquid crystal layer a pretilt angle θp in a range between 88.5° and 89.9° and mono domain alignment during no voltage application; wherein said driver apparatus applies, to said liquid crystal cell, a multiplex driving waveform having a frame frequency f, as a function of a duty number and said pretilt angle θp, said duty number being an inverse of a duty ratio; and wherein: said frame frequency f is not lower than F Hz at a pretilt angle of 88.5° ≦θp <Θ° and not lower than [A 1 ×(θp −Θ)+F] Hz at a pretilt angle of Θ°≦θp≦89.9°, when said duty number is not lower than 4 and not higher than 31, said frame frequency f is not lower than F Hz at a pretilt angle of 88.5°≦θp<Θ° and not lower than [A 2 ×(θp−Θ)+F] Hz at a pretilt angle of Θ°≦θp≦89.9°, when said duty number is not lower than 32 and not higher than D, and said frame frequency f is not lower than F Hz at a pretilt angle of 88.5°≦θp≦89.9°, when said duty number is not lower than (D+1); and wherein said frequency F is not lower than 60 Hz, said angle Θ is not higher than 89.6°, said gradient A 1 is not lower than 120, said gradient A 2 is not lower than 60, and said number D is not lower than 63.
