Direction x is parallel with display panel.Illustrate that first substrate 201 is located at layer of liquid crystal molecule 202 close to display base plate 100 1 in Fig. 1
The light that side namely display base plate 100 are emitted initially enters first substrate 201, subsequently into layer of liquid crystal molecule 202.Optionally, originally
First substrate 201 can also go out positioned at layer of liquid crystal molecule 202 far from 100 side of display base plate namely display base plate 100 in invention
The light penetrated initially enters the second substrate 203, subsequently into layer of liquid crystal molecule 202, first substrate 201 is finally reached, for such
Situation, the present invention herein no longer illustrate by attached drawing.It only with first electrode group Z1 and second electrode group Z2 include two electrodes in Fig. 1
Illustrated for DJ, optionally, the number of electrode can identical not yet in first electrode group Z1 and second electrode group Z2
Together.Optionally, the making material of electrode is transparent material, for example, metal oxide materials, can be indium gallium zinc oxide.
Function structure of polarized light 300 is located at function liquid crystal cell 200 far from 100 side of display base plate, function structure of polarized light 300
The polarization direction for the light that light transmission shaft is emitted perpendicular to display base plate 100;Function structure of polarized light 300 can for glass polaroid or
Wire grating polaroid etc., the present invention to the specific implementation of function structure of polarized light 300 without limitation.It is illustrated in Fig. 1
Structure of polarized light 101 in display base plate 100, the light transmission axis direction of structure of polarized light 101 is (see in figureSignal) perpendicular to paper, then
The polarization direction for the light that display base plate 100 is emitted is perpendicular to paper, and the light transmission shaft f of signaling function structure of polarized light 300 is parallel in figure
In paper.
Display panel includes the first display state, all electrodes under the first display state, into first electrode group Z1
It is passed through first voltage signal, all electrodes into second electrode group Z2 are passed through second voltage signal, first voltage signal magnitude
It is different with second voltage signal magnitude.
As Fig. 2 illustrates, under the first display state, all electrode DJ into first electrode group Z1 are passed through first voltage
Signal then not will form electric field between two electrode DJ adjacent in first electrode group Z1, then two adjacent electrode DJ are corresponding
Layer of liquid crystal molecule in liquid crystal molecule will not rotate;All electrode DJ into second electrode group Z2 are passed through the second electricity
Signal is pressed, liquid crystal molecule of the same reason in the corresponding layer of liquid crystal molecule of electrode in second electrode group Z2 will not occur
Rotation.And since first voltage signal magnitude and second voltage signal magnitude are different, then in adjacent first electrode group Z1 and the
It will form parallel electric field between two electrode group Z2, the liquid crystal molecule for controlling its corresponding position rotates.As illustrated in figure
Under the first display state, layer of liquid crystal molecule is not divided into multiple regions A1 and region A2, wherein region A1 corresponds to liquid crystal molecule
The region to rotate, region A2 correspond to the region that liquid crystal molecule does not rotate.
Under the first display state, area is injected perpendicular to the linearly polarized light of paper in the polarization direction that display base plate 100 is emitted
After the A2 of domain, then penetrates function liquid crystal layer and reach function structure of polarized light 300, since the polarization direction of linearly polarized light does not change
Become, so the linearly polarized light cannot penetrate function structure of polarized light 300, namely there is no light outgoing in the corresponding region region A2;It is aobvious
After showing that region A1 is injected perpendicular to the linearly polarized light of paper in the polarization direction of the outgoing of substrate 100, due to liquid crystal molecule in the A1 of region
It rotates, the polarization direction of linearly polarized light can change, and liquid crystal molecule rotational angle is 0 °~45 ° (including 45 °).Work as liquid
When brilliant molecule rotates 45 °, 90 ° of the change of polarized direction of linearly polarized light, the polarization direction of linearly polarized light and function polarisation knot at this time
The light transmission axis direction of structure 300 is identical, and light is emitted after capable of penetrating function structure of polarized light 300;When liquid crystal molecule is rotated less than 45 °
When, the change of polarized direction angle of linearly polarized light is less than 90 °, the polarization direction of linearly polarized light and function structure of polarized light 300 at this time
Light transmission axis direction be in non-90 degree angle, linearly polarized light can penetrate the outgoing of function structure of polarized light 300, but have certain light loss
It loses, brightness can be less than the brightness for the light being emitted when liquid crystal molecule rotates 45 ° by the corresponding position region A1.Illustrate in such as figure by
The part that display base plate 100 is emitted is in the light of larger tilt angle due to inclined with direction e (for the direction perpendicular to display panel)
Vibration direction is vertical with the light transmission shaft of function structure of polarized light 300, and cannot be emitted through function structure of polarized light 300.Shape is shown first
Under state, in display panel: the corresponding position region A1 is equivalent to transparent area, and the corresponding position region A2 is equivalent to non-transparent
Area;In a first direction on x, region A1 is successively alternately arranged with region A2, is equivalent to and is formd equivalent grating in display panel
Structure.The linearly polarized light for being in larger tilt angle with direction e of display base plate outgoing cannot be inclined through function liquid crystal cell and function
It is emitted after photo structure, to realize the visible angle for the display panel that narrows.
Display panel provided by the invention is disposed with function liquid crystal layer and function polarisation knot on display base plate
Structure is provided with functional electrode layer in function liquid crystal layer, and the light transmission shaft that function structure of polarized light is arranged is emitted perpendicular to display base plate
Light polarization direction.Under the first display state, the electrode into first electrode group and second electrode group is passed through difference respectively
Voltage signal controlled in corresponding region so that forming parallel electric field between adjacent first electrode group and second electrode group
Liquid crystal molecule rotate, display base plate outgoing linearly polarized light penetrate this partial turn liquid crystal molecule rear polarizer direction hair
Raw to change, i.e. the polarization direction of the light of arrival function structure of polarized light and the light transmission axis direction of function structure of polarized light is in non-90 degree angle,
Luminous energy line penetrates the outgoing of function structure of polarized light, and the region that light can be emitted is transparent area;And the electrode in first electrode group
Between and second electrode group in electrode between not will form electric field, then the liquid crystal molecule in corresponding region will not occur
Rotation, linearly polarized light cannot penetrate function structure of polarized light, and the impenetrable region of light is alternatively non-transparent district.State is shown first
