Display panels includes first substrate 210 second substrate relative with first substrate 210 220, liquid crystal molecule 240, black matrix 221 and the first electrode layer.
First substrate 210 is optionally array base palte.In certain embodiments, array base palte 210 is formed with gate line, data wire, thin film transistor (TFT).Wherein, a plurality of gate line and the orthogonal setting of a plurality of data lines, thin film transistor (TFT) is used for carrying out on-off control.The region that a plurality of gate line and a plurality of data lines surround limits pixel region.Multiple pixel regions 230 that first substrate 210 includes in the row direction (X-direction) and column direction (Y-direction) arranges.In a preferred embodiment, line direction (X-direction) and column direction (Y-direction) are vertical.In some change case, line direction (X-direction) and column direction (Y-direction) can also out of plumb.Pixel region specifically described herein includes but not limited to Y-direction arrangement in X direction: multiple pixel regions align in the x-direction and the z-direction, the pixel region of different rows staggers in the Y direction, the pixel region of different lines staggers in the X direction.In other words, do not limit the arrangement of pixel region herein, only describe the bearing of trend of the arrangement of multiple pixel region with X-direction or Y-direction.
Second substrate 220 is optionally color membrane substrates.Second substrate 220 is provided with black matrix 221.Black matrix 221 has the opening of corresponding multiple pixel region 230, is provided with color blocking material 222 in each opening.Color blocking material 222 can include red color resistance material, green color blocking material and blue color blocking material.
Liquid crystal molecule 240 is between first substrate 210 and second substrate 220, and has initial alignment direction.In the first embodiment shown in Fig. 4, liquid crystal molecule 240 is negative liquid crystal molecule, and its initial alignment direction is parallel and Y-direction.
First electrode layer is arranged on first substrate 210.First electrode layer includes the first electrode 250 being arranged in each pixel region 230.First electrode 250 is optionally pixel electrode.First electrode 250 can be made up of transparent metal material.Data wire is sent to the voltage of the first electrode 250 and carries out on-off control by the thin film transistor (TFT) of first substrate 210.First electrode 250 can control the deflection of liquid crystal molecule 240.Each first electrode 250 includes first electrode 251 and multiple second electrode 252.
First electrode 251 is blocked by black matrix 221.First electrode 251 extends approximately along the bearing of trend of data wire.The initial alignment direction of liquid crystal molecule is arranged according to the bearing of trend of first electrode 251, so that the liquid crystal molecule 240 of first electrode 251 correspondence does not deflect substantially.In other words, the setting of first electrode 251 bearing of trend makes the liquid crystal molecule 240 of black matrix 221 correspondence between neighbor district 230 substantially not deflect, and then alleviates the colour mixture problem in neighbor district 230 under the big visual angle caused of liquid crystal molecule 240 of black matrix 221 correspondence.
Specifically, in the embodiment shown in fig. 4, the initial alignment direction of negative liquid crystal molecule 240 is parallel to Y-direction, in order to make the negative liquid crystal molecule 240 of first electrode 251 correspondence substantially not deflect, the bearing of trend of first electrode 251 is parallel to the initial alignment direction of negative liquid crystal molecule 240.That is, the parallel Y-direction of bearing of trend of first electrode 251, the electric field making negative liquid crystal molecule 240 place of correspondence is perpendicular to the initial alignment direction of negative liquid crystal molecule 240, and then makes negative liquid crystal molecule 240 when first electrode 251 energising, does not substantially deflect.Alternatively, interior first electrode 251 of each pixel region 230 width d in the row direction is be more than or equal to 1.5 microns, and less than or equal to 3.5 microns.First electrode 251 width d in the row direction can change with the demand of the resolution of display panels 100 and making technology.
Multiple second electrode 252 are connected with first electrode 251, and the bearing of trend of bearing of trend Z and the first electrode 251 of each second electrode 252 is angled.In the embodiment shown in fig. 4, multiple second electrode 252 in the first electrode 250 are parallel, and bearing of trend is identical.Alternatively, the included angle A between bearing of trend Z and the X-direction of each second electrode 252 is be more than or equal to 7 °, and less than or equal to 14 °.The liquid crystal molecule 240 that each second electrode 252 controls not blocked by black matrix 221 in pixel region 230 deflects.
Alternatively, in first electrode 250, the adjacent interval S between two second electrodes 252 is be more than or equal to 1.5 microns, and less than or equal to 4.5 microns.Interval S between two second electrodes 252 refers to the vertical dimension between two borders of adjacent two second electrodes 252.Alternatively, the width W of each second electrode 252 is be more than or equal to 1.5 microns, and less than or equal to 4.5 microns.The width W of second electrode 252 refers to the vertical dimension between two borders of single second electrode 252.Interval S and the width W of second electrode 252 between second electrode 252 can change with the demand of the resolution of display panels 100 and making technology.

Specifically, in conjunction with Fig. 2 and Fig. 3, the advantage that the first electrode pattern provided by the invention brings is described.According to Fig. 3, due to the first electrode provided by the invention, liquid crystal molecule 240 under black matrix 221 between neighbor district 230 is not deflected, and then the problem owing to first substrate 210 and second substrate 220 para-position deviation cause the liquid crystal molecule 240 of 221 times deflections of black matrix to produce colour mixture with neighbor district 230 in the situation of big visual angle can be alleviated.
Further, reference table 1.Table 1 is to show red picture, it is shown that first substrate 210 and the first deflection angle of the liquid crystal molecule 240 plane at display floater place under the different para-position deviation (MA) of second substrate 220, different black matrix 221 positions.If it will be understood by those skilled in the art that, the first deflection angle of liquid crystal molecule 240 is more big, then the luminous flux penetrating into neighbor district is more big, and during big visual angle, colour mixture is more obvious.According to table 1, under same para-position deviation (MA), 221 times F and G positions of black matrix (boundary position of E, G respectively black matrix 221, F is the point midway of E, G), the first deflection angle of the liquid crystal molecule 240 that the first deflection angle of liquid crystal molecule 240 both is greater than in the present invention in prior art.As can be seen here, the pattern of first electrode 250 of the present invention can be effectively improved big visual angle color colour cast.In like manner, compared to existing technology, F and the G position liquid crystal molecule 240 of embodiment illustrated in fig. 4 is also less at the second deflection angle of the plane at vertically displayed panel 100 place, the problem effectively improving big visual angle colour cast equally.

Further, reference table 2, after table 2 illustrates emulation, first substrate 210 and the light transmittance of display panels under the different para-position deviation (MA) of second substrate 220.According to simulation result it can be seen that under same para-position deviation, the light transmittance of display panels 200 provided by the invention is more than the light transmittance of display panels 100 compared to existing technology.When para-position deviation MA is 0, the penetrance of display panels 200 provided by the invention improves 11.7% than the display panels 100 of prior art.In other words, the present invention substantially increases the light transmittance of liquid crystal indicator by the setting of first electrode 251 and the bearing of trend of second electrode 252.

| Light transmittance of the present invention | 3.02% | 3.24% | 2.98% |
| Existing design light transmittance | 2.73% | 2.90% | 2.77% |
