Abstract
A liquid crystal display device having 2 pixel multi-domain type pixels, in which columnar spacers are disposed in optimal positions. Each of plural video lines has a first portion in which an acute-angled crossing angle of two crossing angles crossing each of scanning lines becomes a positive angle in a clockwise direction from each of the scanning lines, and a second portion in which an acute-angled crossing angle of the two crossing angles crossing each of scanning lines becomes a negative angle in the clockwise direction from each of the scanning lines. The first and second portions are alternately disposed so as to hold the scanning line between them.
Claims20
A liquid crystal display device having plural pixels, comprising:
- a first substrate;
- and
- a second substrate,
- wherein said first substrate has:
- plural scanning lines disposed in a second direction so as to extend in a first direction perpendicular to the second direction;
- and
- plural video lines disposed in the first direction so as to extend in the second direction while they are bent,
- each of said video lines has:
- a first portion in which an acute-angled crossing angle of two crossing angles crossing each of said scanning lines becomes a positive angle in a clockwise direction from each of said scanning lines;
- and
- a second portion in which the acute-angled crossing angle of the two crossing angles crossing each of said scanning lines becomes a negative angle in a clockwise direction from each of said scanning lines,
- said first portion and said second portion are alternately disposed so as to hold the scanning line between them,
- said second substrate has columnar spacers which are respectively disposed in crossing portions where said plural scanning lines cross said video lines,
- each of said pixels is composed of a pixel of a first color, a pixel of a second color, and a sub pixel of a third color which are disposed in order along the first direction,
- said sub pixel of the second color is a sub pixel of a green color,
- each of said columnar spacers has a main columnar spacer and a sub columnar spacer, and
- when let a scanning line A be one of the odd-numbered scanning line and the even-numbered scanning line, and let a scanning line B be the other scanning line,
- said main columnar spacer is disposed in a crossing position where said scanning line A crosses the video scanning line provided between said sub pixel of the third color and said sub pixel of the first color which are adjacent to each other, and
- said sub columnar spacer is disposed in a crossing position where said scanning line B crosses the video scanning line provided between said sub pixel of the third color and said sub pixel of the first color which are adjacent to each other.
