Below in conjunction with accompanying drawing, the display panels provide the utility model embodiment and the embodiment of display device are described in detail.
Wherein, the actual proportions of the shape in the thickness of each rete and region not reflecting liquid crystal display panel in accompanying drawing, object just signal illustrates the utility model content.
The utility model embodiment provides a kind of display panels, as shown in Figure 2 a, comprise: the subtend substrate 10 be oppositely arranged and array base palte 20, and the liquid crystal layer 30 be filled between subtend substrate 10 and array base palte 20, be respectively arranged with the alignment films 40 (in Fig. 2 a, arrow shows frictional direction) with contrary frictional direction on the surface that subtend substrate 10 is relative with array base palte 20, this display panels has multiple pixel cell be arranged in array:
Two pixel region A and B are divided into along the frictional direction of alignment films 40, as shown in Figure 2 a at each pixel cell;
In each pixel cell, the subtend substrate 10 that at least arbitrary pixel region is corresponding or array base palte 20 are dip plane towards the surface of liquid crystal layer side, make the average of the angle of the major axis of the liquid crystal molecule in two pixel region A and B liquid crystal layer 30 corresponding respectively and subtend substrate 10 and array base palte 20 place surface level have identical absolute value, and and be zero.
Due in existing display panels, when the major axis of the liquid crystal molecule in liquid crystal layer and the angle direction of subtend substrate and array base palte place surface level all arrange along same direction, namely when liquid crystal molecule only has a kind of heeling condition, from during left sides and when observing from right side, the phase delay of the liquid crystal molecule in liquid crystal layer is different, cause the color observed slightly different, namely observe display panels respectively from visual angle, left and right and present blueness and yellow, in order to avoid respectively from left and right view to the different problem of color, the display panels that the utility model embodiment provides is divided into two pixel regions at each pixel cell along the frictional direction of alignment films, in each pixel cell, the subtend substrate that at least arbitrary pixel region is corresponding or array base palte are dip plane towards the surface of liquid crystal layer side, particularly, can comprise: pixel region is dip plane relative to the subtend substrate of the correspondence of another pixel region or array base palte towards the surface of liquid crystal layer side, or pixel region is dip plane relative to the subtend substrate of the correspondence of another pixel region and array base palte towards the surface of liquid crystal layer side, or pixel region is dip plane relative to the subtend real estate of the correspondence of another pixel region to the surface of liquid crystal layer side, another pixel region is dip plane relative to the array base palte of the correspondence of a pixel region towards the surface of liquid crystal layer side.Owing to having above-mentioned dip plane, liquid crystal molecule in liquid crystal layer has different heeling conditions at two pixel regions respectively, the average of the angle of the major axis of the liquid crystal molecule in two pixel regions liquid crystal layer corresponding respectively and subtend substrate and array base palte place surface level is made to have identical absolute value, and and be zero, when can ensure so respectively from left and right view, liquid crystal molecule in liquid crystal layer is consistent in the phase delay of two pixel regions, therefore respectively from left and right view to color be identical, thus viewing angle characteristic can be improved further, improve the picture quality of liquid crystal display.
In the specific implementation, in the above-mentioned display panels that the utility model embodiment provides, during in order to ensure further respectively from left and right view, the phase delay total in two pixel region A and B of liquid crystal molecule in the liquid crystal layer that two pixel regions are corresponding is respectively on all four, as shown in Figure 2 a, the size of two pixel region A and B in each pixel cell is traditionally arranged to be equal, when would not have so respectively from left and right view, the phase delay of the liquid crystal molecule in the liquid crystal layer of a part is inconsistent, there is the phenomenon that color is not identical.
Particularly, in one embodiment, in the above-mentioned display panels that the utility model embodiment provides, in two pixel regions, there is heeling conditions different separately in order to make the liquid crystal molecule in liquid crystal layer, in each pixel cell, pixel region can be set to dip plane relative to the subtend substrate of the correspondence of another pixel region or array base palte towards the surface of liquid crystal layer side, and the side that the friction that the height of dip plane point is alignment films starts, as shown in Figure 2 a, pixel region B is set to dip plane relative to the array base palte 20 of the correspondence of pixel region A towards the surface of liquid crystal layer 30 side, and the side that the friction that the height of dip plane point is alignment films 40 starts.
And, in order to the average of the angle ensureing the major axis of the liquid crystal molecule that two pixel regions are corresponding respectively and subtend substrate or array base palte place surface level has identical absolute value, and and be zero, as shown in Figure 2 a, when pixel region B is set to dip plane relative to the array base palte 20 of the correspondence of pixel region A towards the surface of liquid crystal layer 30 side, the tilt angle γ of the liquid crystal molecule in liquid crystal layer 30 is the angle of long axis of liquid crystal molecule corresponding to dip plane and this dip plane, this dip plane is traditionally arranged to be 4 times of the angle of long axis of liquid crystal molecule in corresponding liquid crystal layer 30 and dip plane relative to the tiltangleθ of array base palte 20 place surface level, namely this dip plane is relative to tiltangleθ=4 γ of subtend substrate 10 or array base palte 20 place surface level.When this dip plane is 4 γ relative to the tiltangleθ of array base palte 20 place surface level, then the major axis of the liquid crystal molecule that dip plane near surface is corresponding is 3 γ relative to the angle of array base palte 20 place surface level, and long axis of liquid crystal molecule corresponding near subtend substrate surface in pixel region B is-γ relative to the angle of subtend substrate 10 place surface level, the angle that the major axis of the liquid crystal molecule that pixel region B is corresponding with respect to the horizontal plane on average gets off is (-γ+3 γ)/2=γ, the major axis of liquid crystal molecule that can be corresponding with pixel region A offsets relative to the angle-γ of array base palte 20 place surface level, the tilt angle mean value of the liquid crystal molecule that then pixel region A is corresponding has identical angle absolute value with the tilt angle mean value of the liquid crystal molecule in pixel region B, namely the major axis of the liquid crystal molecule that two pixel region A and B are corresponding respectively has identical angle absolute value with the angle mean value of subtend substrate or array base palte place surface level, and, the major axis of liquid crystal molecule that two pixel region A and B are corresponding respectively and the angle mean value sum of subtend substrate or array base palte place surface level are zero, namely cancel out each other.Therefore, this dip plane is traditionally arranged to be 4 times of the angle β of long axis of liquid crystal molecule in corresponding liquid crystal layer 30 and dip plane relative to the tiltangleθ of subtend substrate 10 or array base palte 20 place surface level.
Or, in another embodiment, in the above-mentioned display panels that the utility model embodiment provides, in two pixel regions, there is heeling conditions different separately in order to make the liquid crystal molecule in liquid crystal layer, in each pixel cell, pixel region all can be set to dip plane relative to the subtend substrate of the correspondence of another pixel region and array base palte towards the surface of liquid crystal layer side, and the side that the friction that the height of dip plane point is alignment films starts, as shown in Fig. 2 b and Fig. 2 c, pixel region B is set to dip plane relative to the subtend substrate 10 of the correspondence of pixel region A and array base palte 20 respectively towards the surface of liquid crystal layer 30 side, and the side that the friction that the height of dip plane point is alignment films 40 starts.
And, in order to the average of the angle ensureing the major axis of the liquid crystal molecule that two pixel regions are corresponding respectively and subtend substrate or array base palte place surface level has identical absolute value, and and be zero, as shown in Fig. 2 b and Fig. 2 c, when pixel region B is set to dip plane relative to the subtend substrate 10 of the correspondence of pixel region A and array base palte 20 respectively towards the surface of liquid crystal layer 30 side, the tilt angle γ of the liquid crystal molecule in liquid crystal layer 30 is the angle of long axis of liquid crystal molecule corresponding to dip plane and this dip plane, this dip plane all can be set to 2 times of the angle of long axis of liquid crystal molecule in corresponding liquid crystal layer 30 and dip plane relative to the inclined angle alpha of subtend substrate 10 and array base palte 20 place surface level, namely this dip plane is relative to inclined angle alpha=2 γ of subtend substrate 10 and array base palte 20 place surface level.When this dip plane is 2 γ relative to the inclined angle alpha of subtend substrate 10 and array base palte 20 place surface level, then the major axis of the liquid crystal molecule of the near surface of dip plane is γ relative to the angle of subtend substrate 10 and array base palte 20 place surface level, the angle that the major axis of the liquid crystal molecule that pixel region B is corresponding with respect to the horizontal plane on average gets off is (γ+γ)/2=γ, the major axis of liquid crystal molecule that can be corresponding with pixel region A offsets relative to the angle-γ of array base palte 20 place surface level, the tilt angle mean value of the liquid crystal molecule that then pixel region A is corresponding has identical angle absolute value with the tilt angle mean value of the liquid crystal molecule in pixel region B, namely the major axis of the liquid crystal molecule that two pixel region A and B are corresponding respectively has identical angle absolute value with the angle mean value of subtend substrate and array base palte place surface level, and, the major axis of liquid crystal molecule that two pixel region A and B are corresponding respectively and the angle mean value sum of subtend substrate and array base palte place surface level are zero, namely cancel out each other.Therefore, the pitch angle sum of the dip plane of subtend substrate 10 and array base palte 20 should be 4 times of the tilt angle of liquid crystal molecule, therefore, this dip plane is traditionally arranged to be 2 times of the angle β of long axis of liquid crystal molecule in corresponding liquid crystal layer 30 and dip plane relative to the tiltangleθ of subtend substrate 10 and array base palte 20 place surface level.
Or, in another embodiment, in the above-mentioned display panels that the utility model embodiment provides, in two pixel regions, there is heeling conditions different separately in order to make the liquid crystal molecule in liquid crystal layer, in each pixel cell, pixel region can be set to dip plane relative to the subtend real estate of the correspondence of another pixel region to the surface of liquid crystal layer side, another pixel region is dip plane relative to the array base palte of the correspondence of a pixel region towards the surface of liquid crystal layer side, and the side that the friction that the height of this dip plane point is alignment films starts, as shown in Figure 2 d, pixel region A is set to dip plane relative to the subtend substrate 10 of the correspondence of pixel region B towards the surface of liquid crystal layer 30 side, pixel region B is set to dip plane relative to the array base palte 20 of the correspondence of pixel region A towards the surface of liquid crystal layer 30 side, and the side that the friction that the height of dip plane point is alignment films 40 starts.
And, in order to the average of the angle ensureing the major axis of the liquid crystal molecule that two pixel regions are corresponding respectively and subtend substrate or array base palte place surface level has identical absolute value, and and be zero, again because the pitch angle sum of the dip plane of subtend substrate 10 and array base palte 20 should be 4 times of the tilt angle of liquid crystal molecule, therefore, as shown in Figure 2 d, this dip plane can be set to 2 times of the angle of long axis of liquid crystal molecule in corresponding liquid crystal layer 30 and dip plane relative to the angle of inclination beta of subtend substrate 10 and array base palte 20 place surface level.
