Patent ID: 7505105

Claim:
A liquid crystal display device comprising: first and second substrates laid out in such a way as to face each other; an insulating layer provided on that surface of said first substrate which lies on the second substrate side; a common electrode formed on said insulating layer; a pixel electrode formed on said insulating layer as so to be in parallel to said common electrode; a first alignment layer provided so as to cover said insulating layer, said pixel electrode and said common electrode, and subjected to an aligning treatment in a direction which forms an angle of 10 to 20° with a lengthwise direction of said pixel electrode and said common electrode; a second alignment layer provided on that surface of said second substrate which lies on the first substrate side, and subjected to an aligning treatment in a direction which forms an angle of 10 to 20° with said lengthwise direction of said pixel electrode and said common electrode; and a liquid crystal layer arranged between said first alignment layer and said second alignment layer, and comprised of a liquid crystal having a dielectric anisotropy of 8 to 20, wherein a distance between said first alignment layer and said second alignment layer is equal to or less than 2.7 μm, a voltage of 4 to 7V is applied to said pixel electrode when displaying white, and a following expression is satisfied: 11.8 > V white d - 0.6 × L 0.5 × Δ ⁢ ⁢ ɛ - 0.5 > 9.8 where V white (V) is said voltage to be applied to said pixel electrode when displaying white, Δ∈ is said dielectric anisotropy of said liquid crystal, d (μm) is said distance between said first alignment layer and said second alignment layer, and L (μm) is an interval between said pixel electrode and said common electrode.
