Liquid crystal display device

摘要

A liquid crystal display device is constituted such that sub-pixels are disposed in an array form in a first direction and a second direction orthogonal to each other, a plurality of gate lines are disposed in the second direction, an optical element for distributing the light to the second direction is disposed on the liquid crystal display device, liquid crystal molecules of the liquid crystal display device are controlled by an electric field almost in parallel to the surface of the liquid crystal display device, and a data line is disposed to obliquely divide the sub-pixels at a position different from the boundary between the sub-pixels neighboring in the second direction, where the data line can have a small angle with respect to the second direction, and the numerical aperture is not deteriorated greatly even when the lengths of apertures of the sub-pixels in the first direction are constant.

1. A liquid crystal display device, comprising: a first substrate; a second substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate, liquid crystal molecules thereof being controlled by an electric field that is almost in parallel to those substrates, wherein the liquid crystal display device includes:
sub-pixels disposed in an array form in a first direction and a second direction orthogonal to each other; an optical element which distributes light in the second direction; a gate line disposed by being extended to the second direction; a data line disposed to divide the sub-pixel obliquely at a position different from a boundary between the sub-pixels neighboring to each other in the second direction; the sub-pixel includes an aperture section where light is transmitted; a plurality of first electrodes, a plurality of second electrodes, and a single third electrode are disposed in the aperture section; the first electrodes and the second electrodes are disposed alternately at an equivalent interval obliquely at a first angle with respect to the second direction; the third electrode is disposed obliquely at a second angle with respect to the second direction; the data line is disposed under the third electrode via an insulating film; the first electrodes and the second electrodes have an intersection part intersecting with the third electrode and the data line in the aperture section; at the intersection part, a position in the second direction where the first electrodes intersect with one side of the third electrodes matches a position in the second direction where the first electrodes intersect with the other side of the third electrode, and a position in the second direction where the second electrode intersect with one side of the third electrode matches a position in the second direction where the second electrodes intersect with the other side of the third electrode.
