Abstract:
1. A liquid crystal display device comprising: an array substrate that comprises a comb-shaped first electrode, which is a pixel electrode, an insulating layer, and a comb-shaped second electrode arranged in this order, a first longitudinal direction of comb teeth of the comb-shaped first electrode and a second longitudinal direction of comb teeth of the comb-shaped second electrode being parallel to each other, and the array substrate being partitioned into pixel units or sub-pixel units; and a counter substrate that faces the array substrate via a liquid crystal layer and comprises a comb-shaped third electrode, the first longitudinal direction and a third longitudinal direction of comb teeth of the comb-shaped third electrode being parallel to each other, and the counter substrate being partitioned into the pixel units or the sub-pixel units, wherein the liquid crystal layer comprises liquid crystals that have negative dielectric constant anisotropy, and are vertically aligned in an initial state, in a cross-section perpendicular to the first through third longitudinal directions and parallel to a thickness direction of the liquid crystal layer, the first comb-shaped electrode and the third comb-shaped electrode are disposed in a state of facing one another via the liquid crystal layer, and the first through third comb-shaped electrodes are formed at respective positions symmetrical about a central axis in a cross-sectional view of the pixel or the sub-pixel, a position of the comb teeth of the second comb-shaped electrode disposed nearest to the comb teeth of the first comb-shaped electrode is shifted from a position of the comb teeth of the first comb-shaped electrode in a first direction being parallel to surfaces of the array and counter substrates from the central axis, a position of the comb teeth of the third comb-shaped electrode disposed nearest to the comb teeth of the first comb-shaped electrode is shifted from a position of the comb teeth of the first comb-shaped electrode in a second direction that is opposite to the first direction from the central axis, and the comb teeth of the comb-shaped second electrode facing to the comb teeth of the first comb-shaped electrode via the insulating layer comprises a protruding width that protrudes in the first direction from the comb teeth of the first comb-shaped electrode, and the comb teeth of the first comb-shaped electrode and the comb teeth of the second comb-shaped electrode comprise overlapping widths that overlap with each other.
