When corresponding with the 4th electrode branches 1421B field strength is identical, when the 3rd angle T3 is less than the 4th angle T4, i.e. the 3rd electrode point
Branch 1411B bearing of trend is less than the 4th electrode branches 1421B bearing of trend and data wire 12 with the angle of data wire 12
During angle, the component of the electric field that the 3rd electrode branches 1411B is formed in the X direction is more than the 4th electrode branches 1421B formation
The component of electric field in the X direction, for positivity liquid crystal, the component in X-direction is bigger, then the power that liquid crystal 161 is subject to is also bigger,
The angle that liquid crystal 161 deflects is bigger, when being deflected due to liquid crystal 161, and within the specific limits, deflection angle is bigger, then

1421B bearing of trend and the angle in the direction of scan line 13, due to the direction of an electric field E of electrode branches formation and prolonging for electrode branches
Direction is stretched perpendicular, therefore, in the corresponding field strength of the 3rd electrode branches 1411B field strength corresponding with the 4th electrode branches 1421B
When identical, when the 3rd angle T3 is more than the first angle T1, i.e. the 3rd electrode branches 1411B bearing of trend and scan line 13
When angle is less than the 4th electrode branches 1421B bearing of trend and the angle of scan line 13, the 3rd electrode branches 1411B electric field
Component in the Y direction is more than the component of the electric field of the 4th electrode branches 1421B formation in the Y direction, for negative liquid crystal, Y
Component on direction is bigger, then the power that liquid crystal 161 is subject to is also bigger, and the angle that liquid crystal 161 deflects is bigger, due to liquid crystal
161 when deflecting, and within the specific limits, deflection angle is bigger, then light is through the liquid crystal 161 and projects after display panel
Brightness is also bigger, therefore the deflection angle of the corresponding liquid crystal 161 of the 3rd electrode branches 1411B is corresponding more than the 4th electrode branches
