For symmetrical, the electrode zone formed with slit ST5 and the electrode zone formed with slit ST8 on vertical direction axisymmetricly
Distribution, the electrode zone formed with slit ST6 and the electrode zone formed with slit ST7 axisymmetricly divide on vertical direction
Cloth.
This multidomain, which shows that such as eight farmlands are shown, can increase display panel visual angle, and film crystal in control circuit 1101
Pipe T3 and charge share electric capacity Ccs1, Ccs2 setting can realize charge share and show big visual angle colour cast to improve multidomain.Its
In charge share general principle be:First when scan line SLa transmits scanning signal, thin film transistor (TFT) T1 and thin film transistor (TFT)
The respective drain electrodes of T2 and source electrode conducting, the number for making pixel electrode PE1 and pixel electrode PE2 voltage be transmitted in data wire DL
It is believed that number in the presence of reach identical current potential, then when scan line SLb transmits scanning signal, thin film transistor (TFT) T1 and film
The respective drain electrodes of transistor T2 and source electrode cut-off, while thin film transistor (TFT) T3 drain electrode and source electrode conducting, cause picture
Electric charge on plain electrode PE2 is shifted by charge share electric capacity Ccs2 to public electrode distribution VCOM LINE, makes pixel electrode
Voltage on PE2 produces voltage difference with the voltage on pixel electrode PE1, and then makes the liquid crystal point of pixel electrode PE2 regions
Son enters horizontal deflection from the liquid crystal molecule of pixel electrode PE1 regions with different deflection angles, and it is big to reach multidomain display compensation
The technique effect of visual angle colour cast.
Furthermore connection pixel electrode PE2 and extend across pixel electrode PE1 conductive connecting CL typically extend across
More pixel electrode PE1, PE2 stem portion MB regions, therefore it can be light tight plain conductor, it is impermeable to make full use of
The low resistance characteristic of light plain conductor.In other embodiments, conductive connecting CL is preferably electrically conducting transparent line such as ITO conductions
Line, influenceed with the light transmittance reduced on pixel cell 110.
In addition, in figure 3, pixel electrode PE1 and pixel electrode PE2 have different sizes.Implement as replacing

Area；So as to which public electrode region 10 is divided into four pairs in symmetrical point by two spaced pierced patterns 2101,2103 thereon
The public electrode sub-district of cloth.
Further, because human eye is more sensitive to the green glow in three primary colours, feux rouges takes second place, and less sensitive to blue light,
It thus can be designed so that the light transmittance at green color filter G is maximum, Red lightscreening plate R takes second place, and used technological means can
To be：Make the pierced pattern 2101 (and/or pierced pattern 2103) in public electrode region 210 corresponding with green color filter G
Than the size of the pierced pattern 2101 (and/or pierced pattern 2103) corresponding to Red lightscreening plate R in public electrode region 210
Greatly, compare the pierced pattern 2101 (and/or pierced pattern 2103) in public electrode region 210 corresponding with Red lightscreening plate R
The size of pierced pattern 2101 (and/or pierced pattern 2103) corresponding to blue color filter B in public electrode region 210 is big,
So the colored filter of different colours can have different light transmittances, to realize more preferably display effect.
In addition, referring to Fig. 8, for the display panel of specific application scenario, such as LCD TV, to increase its upward angle of visibility
Range, can in pixel cell pixel electrode carry out design for change.Such as previous embodiment is different from by pixel electrode
PE1 (PE2) area is substantially divided into the quartering to obtain four electrode zones, in embodiment is changed, by pixel electrode PE1
(PE2) top half (part of neighbouring control circuit 1101, scan line SLa and scan line SLb) is divided into four electrode zones
And the latter half (part away from control circuit 1101, scan line SLa and scan line SLb) is still divided into two electrode zones,
Because the downwards angle of visibility of LCD TV relatively takes less than, and so, the electrode district on same pixel electrode PE1 (PE2)
Slit differently- oriented directivity in domain be respectively 30 °, 60 °, 135 °, 225 °, 300 ° and, 330 °, realize that display panel is wider array of whereby
Upward angle of visibility.
