[the first embodiment]
Fig. 3 A illustrates the partial cutaway schematic of the liquid crystal indicator of the first embodiment of the present invention.Fig. 3 B is according to the partial top view on the first substrate in Fig. 3 A.Referring to Fig. 3 A and Fig. 3 B, the liquid crystal indicator 300 of the present embodiment has multiple first pixel region 300B, multiple second pixel region 300G and multiple 3rd pixel region 300R, and wherein Fig. 3 A and Fig. 3 B only illustrates a first pixel region 300B, the second pixel region 300G and a 3rd pixel region 300R is example.In addition, liquid crystal indicator 300 liquid crystal layer 330 that comprises first substrate 310, second substrate 320 and be configured between first substrate 310 and second substrate 320.
First substrate 310 is configured with respectively at the first dielectric film 310M of the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R
1, the second dielectric film 310M
2with the 3rd dielectric film 310M
3.Wherein, the first dielectric film 310M
1specific inductive capacity be greater than in fact the second dielectric film 310M
2specific inductive capacity, and the second dielectric film 310M
3specific inductive capacity be greater than in fact the 3rd dielectric film 310M
3specific inductive capacity.
Hold above-mentioned, the first substrate 310 of the present embodiment is more configured with multiple pixel electrode 312, plurality of scanning wirings 314 (Fig. 3 B only illustrates a scan wiring 314 for example), many data wirings 316 and multiple active component 318, wherein the first dielectric film 310M

2with the 3rd dielectric film 310M
3such as be positioned at below pixel electrode 312.Scan wiring 314 is roughly along first direction D1 arrangement parallel to each other, data wiring 316 is roughly along second direction D2 arrangement parallel to each other, and data wiring 316 and scan wiring 314 define the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R.Each active component 318 is positioned at corresponding the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R, and is driven by the scan wiring 314 of correspondence.On the other hand, each pixel electrode 312 is positioned at corresponding the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R, and the signal that the active component 318 being electrically connected correspondence transmits to receive corresponding data wiring 316.
For penetration liquid crystal display device or half penetrated half-reflecting liquid crystal display, as shown in Figure 3A, the liquid crystal indicator 300 of the present embodiment also comprises backlight module 340, and first substrate 310, second substrate 320 and liquid crystal layer 330 are configured on backlight module 340, wherein backlight module 340 can provide the light source needed for liquid crystal indicator 300.Certainly, in other instances, the liquid crystal indicator 300 of the present embodiment can also be reflective LCD device.That is the liquid crystal indicator 300 of the present embodiment does not limit the mode or kenel that obtain light source.
Continue referring to Fig. 3 A, in the present embodiment, second substrate 320 is more configured with multiple first color filter film 320B, multiple second color filter film 320G, multiple 3rd color filter film 320R and common electrode layer 322, wherein the first color filter film 320B, the second color filter film 320G and the 3rd color filter film 320R are respectively in the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R.In addition, common electrode layer 322 covers the first color filter film 320B, the second color filter film 320G and the 3rd color filter film 320R.But in other embodiments, the first color filter film 320B in Fig. 3 A, the second color filter film 320G and the 3rd color filter film 320R are also configurable on first substrate 310.
In the present embodiment, the first color filter film 320B is such as blue filter film, and the second color filter film 320G is such as green filter film, and the 3rd color filter film 320R is such as red filter film.Because backlight module 340 can provide backlight to the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R, therefore, when the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R active component 318 by corresponding scan wiring 314 drive to make corresponding pixel electrode 312 receive the signal that corresponding data wiring 316 transmits time, liquid crystal indicator 300 is able to display frame.
Specifically, the light of part backlight can by the first dielectric film 310M of the first pixel region 300B
1and the first color filter film 320B (blue filter film), and the light in part of back source can by the second dielectric film 310M of the second pixel region 300G again

2on the actual cross-pressure experienced of liquid crystal layer, and the second dielectric film 310M
2on the actual cross-pressure experienced of liquid crystal layer be less than the 3rd dielectric film 310M
3the actual cross-pressure experienced of liquid crystal layer, that is when the light of backlight is when entering the first pixel region 300B, light penetration rate does not arrange the first dielectric film 310M
1time low, the light of small amount is by the first color filter film 320B, and the light of backlight is when entering the 3rd pixel region 300R, light penetration rate is higher, relatively large light is by the 3rd color filter film 320R, thus, the light penetration rate of the blue light, green glow and the ruddiness that are formed by the first pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R can be reached unanimity, and just can improve the color offset phenomenon that liquid crystal indicator 300 produces when display frame.
In addition, the first above-mentioned pixel region 300B, the second pixel region 300G and the 3rd pixel region 300R also can be applicable in multi-zone vertical alignment nematic (Multi-domainVerticalAlignment, MVA) liquid crystal indicator.Please refer to Fig. 3 A, in the present embodiment, the pixel electrode 312 being positioned at the first pixel region 300B has multiple first slit S
1, the pixel electrode 312 being positioned at the second pixel region 300G has multiple second slit S
2, the pixel electrode 312 being positioned at the 3rd pixel region 300R has multiple 3rd slit S

1, the second slit S
2with the 3rd slit S
3the change of neighbouring direction of an electric field can be caused, and then make the liquid crystal molecule of liquid crystal layer 330 be multiple domain arrangement, broader visual angle can be produced to make liquid crystal indicator 300.
Because the electric field of slit centre is more weak, the specification power therefore for liquid crystal molecule is less, and then light transmittance is declined.Thus, as the first slit S
1width W 1 be greater than in fact the second slit S
2width W 2 and the second slit S
2width W 2 be greater than in fact the 3rd slit S
3width W 3 time, the first slit S
1the degree that light transmittance is declined just is greater than the second slit S
2make the degree that light transmittance declines, and the second slit S
2the degree that light transmittance is declined is greater than the 3rd slit S
3make the degree that light transmittance declines, the object that the light penetration rate of blue light, green glow and ruddiness is reached unanimity can be reached further.
But the present invention does not limit the first slit S
