    Abstract: The displacement between a TFT substrate and a counter substrate and the cut of an alignment film caused by a columnar spacer are prevented. A liquid crystal display device includes: a TFT substrate including a scanning line extending in a first direction, a picture signal line extending in a second direction, a pixel electrode formed in a region surrounded by the scanning line and the picture signal line, and a common electrode formed as opposed to the pixel electrode through an insulating film; a counter substrate disposed as opposed to the TFT substrate and having a spacer; and a liquid crystal sandwiched between the substrates. A common metal interconnection is formed to cover the picture signal line or the scanning line, and stacked on the common electrode. A through hole is formed on the common metal interconnection. The tip end of the spacer is disposed inside the through hole.

    Abstract: Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.

    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.
