no. 1 Embodiment

[0052] A liquid crystal display device according to a first embodiment of the present invention will be described below with reference to FIG. 1 . In FIG. 1 , the same constituent parts as those in FIG. 12 are denoted by the same reference numerals. Three subpixels corresponding to red, green, and blue (hereinafter referred to as R subpixels, G subpixels, and B subpixels, respectively) are regarded as one pixel, and a plurality of pixels are arranged in a matrix on a TFT substrate. In each of the R sub-pixel, G sub-pixel, and B sub-pixel, the gate line GL extends in the left-right direction (horizontal direction), and the display signal line DL extends in the vertical direction so as to cross the gate line GL ( vertical direction). A thin film transistor TR is disposed near the intersection of the gate line GL and the display signal line DL, and a subpixel electrode 60 connected to the thin film transistor TR for subpixel selection is provided. A common electrode 62-1 is provi...

[0056] Next, a second embodiment of the present invention will be described with reference to FIG. 2 . In FIG. 2 , the same constituent parts as those in FIG. 12 are denoted by the same reference numerals. In this embodiment, three sub-pixels of R sub-pixel, G sub-pixel, and B sub-pixel are regarded as one pixel, and a plurality of pixels are arranged in a matrix, but only four sub-pixels are shown in FIG. 2 .

[0057] The difference from the first embodiment is that a plurality of slits S2 are opened in the common electrode 62-2, and each slit S2 extends in the left and right directions with a width of 2 sub-pixels, and the slits S2 of this kind are arranged in a mutual Dots in the vertical direction are arranged so as to be shifted by the width of 1 sub-pixel in the horizontal direction. That is, the slits S2 in the second row below the slits S2 in the first row are shifted by the width of one sub-pixel in the left-right direction relative to the slits S2 in the first row. ...

no. 3 Embodiment

[0060] Next, a third embodiment of the present invention will be described with reference to FIG. 3 . In FIG. 3 , the same constituent parts as those in FIG. 12 are denoted by the same reference numerals. In this embodiment, three sub-pixels of R sub-pixel, G sub-pixel, and B sub-pixel are regarded as one pixel, and a plurality of pixels are arranged in a matrix, but only five sub-pixels are shown in FIG. 3 .

[0061] The difference from the first embodiment is that: a plurality of slits S3 are opened in the common electrode 62-3, and each slit S3 extends in the left and right direction with a width of 3 sub-pixels, and the slits S3 of this kind are mutually arranged in the left and right directions. The dots in the vertical direction are arranged such that the direction is shifted by the width of 1 sub-pixel. That is, with respect to the slit S3 in the first row, the slit S3 in the second row below it is shifted by the width of one sub-pixel in the left-right direction relat...

Abstract

The invention improves the penetration rate and contrast grade in a FFS mode liquid crystal display device; wherein, a Sub-pixel R, a Sub-pixel G and a Sub-pixel B are taken as a Pixel 1, and a plurality of pixels are arranged into a matrix shape. In each the sub-pixel, a grid line (GL) extends to the left and right, a display signal line extends to the upper and lower direction by intercrossing the grid line (GL). A thin film transistor TR is arranged near the crossing point of the grid line (GL) and the display signal line for the option of the sub-pixels, and a sub-pixel electrode (60), which is connected with the thin film transistor TR, is positioned near the crossing point. A common electrode (62-1) is arranged above the sub-pixel electrode (60), separated by an insulation film. A plurality of slots (S1) is positioned at the common electrode (62-1), traversing on the left and right direction in each pixel, and an edge (SE1) is arranged on a bound of each pixel.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device in which the alignment direction of liquid crystal molecules is controlled by a transverse electric field between electrodes on the same substrate. Background technique [0002] As one of the means to achieve a wide viewing angle of the liquid crystal display device, a method has been developed to generate a horizontal electric field between electrodes on the same substrate, so that the liquid crystal molecules can be rotated in a plane parallel to the substrate through the electric field, In this way, the liquid crystal display device has an optical switching function. As an example of this technology, there are known horizontal electric field control (In-Plane Switching, hereinafter referred to as "IPS") method, and fringe electric field control (Fringe-Field Switching, hereinafter referred to as "FFS") obtained by improving the IPS meth...
