In embodiment tri-, referring to Figure 11, because the first electrode 42 and the second electrode 43 are all arranged on array base palte 22 inner sides, and the first electrode 42 and the second electrode 43 be arranged in parallel, therefore, the first electrode 42 and the second electrode 43 form the liquid crystal drive pattern of IPS type (In-Plane Switching, plane conversion type), the wide viewing angle drive pattern that liquid crystal drive pattern Ye Shi liquid crystal circle of this type is developed for solving large scale, high definition tabletop display and LCD TV application.In the embodiment of the present invention three, by the liquid crystal drive pattern of IPS type, can under "on" position, control the rotation of the liquid crystal molecule 231 of the first electrode 42 and the second electrode 43 formed electric field regions.
As described in embodiment mono-and embodiment bis-, display panels can be divided into normal black pattern and normal white mode according to residing state in the situation that not powering up.In order to reduce better the black state of display panels, to prevent opening 41 place's light leaks, the display panels of the liquid crystal drive pattern of IPS type adopts normal black pattern conventionally.Under normal black pattern, preferably, opening 41 is positioned at the first adjacent electrode 42 and the middle part of the second electrode 43, and to prevent that the voltage of the first electrode 42 and the second electrode 43 is subject to the impact of other voltages, making the pressure reduction between the first electrode 42 and the second electrode 43 is not 0.Even if being subject to the impact of other voltages, to make the voltage difference between the first electrode 42 and the second electrode 43 be not 0, but the transmitance of light that is positioned at the middle part of the first adjacent electrode 42 and the second electrode 43 is minimum, can prevent better like this opening 41 place's light leaks.
Preferably, the inner side of described array base palte 22 has public electrode 27, and described the first electrode 42 is identical with the current potential of public electrode 27.In embodiment tri-, liquid crystal drive pattern due to the first electrode 42 and the second electrode 43 formation IPS types, for the impact that makes the light tight while of liquid crystal molecule of the first electrode 42 and the second electrode 43 formed electric field regions can avoid again the current potential of the first electrode 42 to rotate the liquid crystal molecule of viewing area 31, the current potential of the first electrode 42 can be arranged to identical with the current potential of public electrode 27, the current potential that the current potential of the first electrode 27 is common electric voltage, meanwhile, also make that the first electrode 42 is applied to control signal and become more convenient.
In addition, the current potential of the first electrode 42 can be not identical with the current potential of public electrode 27 yet, and can set as required.It should be noted that, in embodiment tri-, the current potential of the first electrode 42 is not construed as limiting.
Current potential for the second electrode 43, can set as required, the electric field controls that makes between the first electrode 42 and the second electrode 43 to form is positioned at the rotation of the liquid crystal molecule of this electric field region, guarantee to make the liquid crystal molecule in this region light tight when display panels is worked, to prevent opening 41 place's light leaks.
Alternatively, the gap between described opening 41 and described the first electrode 42 and the second electrode 43 is overlapping in printing opacity direction.Due to the formed electric field of two electrodes of the gap location between the first electrode 42 and the second electrode 43 a little less than, therefore, can be controlled at better the rotation situation of this gap location liquid crystal molecule 231.If it is overlapping in printing opacity direction that the Yu Gai gap, position of opening 41 is set, by controlling better the rotation situation of this gap location liquid crystal molecule 231, can prevent better opening 41 light leaks.
Preferably, referring to Figure 11, described array base palte 22 inner sides are also provided with barrier bed 47, and described barrier bed 47 is at least arranged on the adjacent gap of described the first electrode 42 and described the second electrode 43.Owing to inevitably there is the settings such as cabling cross-over connection in the adjacent gap location of the first electrode 42 and the second electrode 43, this arranges and can cause the edge of electrode to occur step, and may produce light leak at step place, therefore, for fear of producing light leak at this step place, barrier bed 47 need be set, so that the effect of being in the light is played to by this step place.Further, described barrier bed 47 is amorphous silicon light blocking layer or metal light blocking layer.Preferably, described barrier bed 47 is amorphous silicon light blocking layer.Because metal light blocking layer can reflection ray, when barrier bed 47 is metal light blocking layer, the light shining it from metal light blocking layer top can be reflected, for example, after the light that is irradiated to opening 41 inwalls is reflected, shines on metal light blocking layer and be reflected, can cause like this opening 41 light leaks, yet amorphous silicon light blocking layer is better to the absorption of light, if barrier bed 47 is amorphous silicon light blocking layer, can weakens to a great extent and even avoid due to opening 41 light leaks that cause of reflection.
