Problems solved by technology

The IPS mode liquid crystal display panel 50 has the advantages of wide viewing angle and high contrast, but since the counter electrode 55 is formed of the same metal material as the common wiring 53 and even the scanning line 52, the aperture ratio and transmittance are low. Very low, and there is also the problem that the change of viewing angle will cause the color to change

Embodiment 1

[0093] The liquid crystal display panel of embodiment 1 has: array substrate, and this array substrate has common electrode, the insulating film that is formed on the common electrode, the pixel electrode that is formed on the insulating film; There is the color filter substrate of color filter layer; The liquid crystal layer sandwiched by the color filter substrate; the liquid crystal display panel drives the liquid crystal layer through the electric field generated between the common electrode and the pixel electrode, which is also called the so-called FFS mode liquid crystal display panel. use figure 1 The manufacturing flow of the FFS mode liquid crystal display panel 10A of the first embodiment will be described with reference to FIG. 3 . in, figure 1 It is a schematic plan view showing transparently one pixel of the color filter substrate and the alignment film of the FFS mode liquid crystal display panel of Example 1, figure 2 is along figure 1 Sectional view of ...

Embodiment 2

[0107] Then use Figure 4 The FFS mode liquid crystal display panel 10B of the second embodiment will be described. in, Figure 4 It is a schematic plan view showing transparently one pixel of the color filter substrate and alignment film of the FFS mode liquid crystal display panel of Example 2. and, Figure 4 neutralize figure 1 as well as figure 2 Portions of the FFS mode liquid crystal display panel 10A of the illustrated embodiment 1 having the same structure are given the same reference numerals, and detailed description thereof is omitted.

[0108] The difference in structure between the FFS mode liquid crystal display panel 10B of the second embodiment and the liquid crystal display panel 10A of the first embodiment is that the plurality of slits 20B arranged on the pixel electrodes 21 are arranged on the adjacent scanning lines 12 relative to each other. For the common wiring 13 between them, it is arranged in a state of inclination in different directions in a...

Embodiment 3

[0114] use below Figure 5 The FFS mode liquid crystal display panel 10C of the third embodiment will be described. in, Figure 5 It is a schematic plan view showing transparently some pixels of the color filter substrate and the alignment film of the FFS mode liquid crystal display panel of Example 3. And, for Figure 5 neutralize figure 2 and figure 2 Portions of the FFS mode liquid crystal display panel 10A shown in Embodiment 1 having the same structure are given the same reference numerals, and a detailed description thereof is omitted.

[0115] The difference in structure between the FFS mode liquid crystal display panel 10C of the third embodiment and the liquid crystal display panel 10A of the first embodiment is that each pixel is arranged in a triangle in a different manner on each row, and each pixel A plurality of slits 20C are inclined in opposite directions to each other on the odd-numbered rows and the even-numbered rows, and its other structure is the sa...

Abstract

The liquid crystal display panel 10A according to the present invention is in the FFS mode, and includes an array substrate having first electrodes 14 formed in regions divided by a plurality of scanning lines 12 and signal lines 17, and the above-mentioned first electrodes 14. A plurality of slits 20A provided on the second electrode 21 in parallel to each other in the direction intersecting with the signal line 17 described above; a color filter substrate having a color filter layer; The characteristics are: one end 20A' side of the plurality of slits 20A is open; the center line 30 of the color filter layer is along the direction of the signal line 17 corresponding to each pixel, and the center line 30 is viewed from a plane. The display center line shifted from the center line 31 of the second electrode 21 to the open end side of the slit matches. By having the above structure, it is possible to provide an FFS mode liquid crystal display panel that does not cause color mixing when one end side of the slit provided in each of the second electrodes is in an open state.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, that is, a so-called fringe field switching (Fringe Field Switching, hereinafter referred to as "FFS") mode liquid crystal display panel, which is provided with a pair of substrates that sandwich a liquid crystal layer. A common electrode on a substrate, and a pixel electrode formed with an insulating film between the common electrode, and the liquid crystal display panel drives the liquid crystal layer through an electric field generated between the common electrode and the pixel electrode, especially involving a bright liquid crystal The display panel prevents color mixture from occurring by checking the positional relationship between the pixel electrodes and the color filters when one end side of the slit provided in each pixel electrode is in an open state. Background technique [0002] In recent years, liquid crystal display panels are frequently used not only in information communi...
