Abstract:
1. A liquid crystal display apparatus, comprising: an array substrate comprising a common electrode, an insulating film disposed on the common electrode, a plurality of pixel electrodes each disposed on the insulating film to be opposite to the common electrode and including a slit, and a first alignment film covering the insulating film and the pixel electrodes; a counter-substrate comprising a second alignment film arranged opposite to the first alignment film; and a liquid crystal layer held between the array substrate and the counter-substrate, and formed by a negative liquid crystal material, wherein the liquid crystal layer comprises liquid crystal molecules which form a bias angle in a direction substantially orthogonal to a direction of extension of the slit and which are initially aligned, and the first alignment film, the liquid crystal layer and the bias angle have a relationship of where a capacitance of the first alignment film is C_PI, a capacitance of the liquid crystal layer is C_LC, and the bias angle is θ, the capacitance of the first alignment film is a value obtained by dividing a dielectric constant of the first alignment film by a thickness of the first alignment film, and the capacitance of the liquid crystal layer is a value obtained by dividing a specific dielectric constant of the liquid crystal layer in a direction vertical to a longer axis of the liquid crystal molecules by a thickness of the liquid crystal layer.
