Plain unit.Therefore, the effect which shows in dark-state is preferable, and the display effect of liquid crystal display panel is preferable.
Optionally, liquid crystal adjacent with array substrate in the liquid crystal in a region can be the first liquid crystal, with color film base
The adjacent liquid crystal of plate can be the second liquid crystal, and the differently- oriented directivity of first liquid crystal can be perpendicular to the differently- oriented directivity of the second liquid crystal.
Assuming that the differently- oriented directivity of the liquid crystal in a region is preset direction, then it is default can be parallel to this for the differently- oriented directivity of the first liquid crystal
Direction, and the differently- oriented directivity of the second liquid crystal can be perpendicular to the preset direction, alternatively, the differently- oriented directivity of the first liquid crystal can be vertical
It can be parallel to the preset direction in the differently- oriented directivity of the preset direction, and the second liquid crystal.
For example, in Fig. 1 and Fig. 3, which is the directions x, which is first area, another area
Domain is second area, that is to say that the differently- oriented directivity of the liquid crystal opposite with color blocking block is identical, the orientation of the liquid crystal opposite with black matrix
Light direction (that is to say the directions y in the figure) gradual change of direction along liquid crystal display panel.In Fig. 1, the orientation side of the first liquid crystal
It is perpendicular to the direction (namely perpendicular to the directions x) of paper, in figure 3, first to the differently- oriented directivity for the directions x, the second liquid crystal
The differently- oriented directivity of liquid crystal is perpendicular to the direction of paper, and the differently- oriented directivity of the second liquid crystal is the directions x.As shown in figure 3 for Fig. 1
The absorption axiss of liquid crystal display panel, down polaroid can be parallel with the absorption axiss of upper polaroid (assuming that the suction of two polaroids
Axis is received each parallel to the directions x).The liquid crystal display panels of Fig. 1 as shown in figure 3 can be advanced super dimension field switch (English：
Advanced-Super Dimensional Switching；Abbreviation ADS) type liquid crystal display panel.
Also shown in the liquid crystal display panels of Fig. 1 as shown in figure 3 pixel unit A in liquid crystal display panel and and its
Adjacent pixel unit B, if pixel unit A and pixel unit B is required to show in illuminated state, backlight can become by down polaroid
For linearly polarized light, and polarization direction is perpendicular to the direction (that is to say the direction perpendicular to the directions x) of paper.In the linearly polarized light
Part linearly polarized light pass through liquid crystal and the liquid crystal rear polarizer direction in pixel unit B in pixel unit A constant namely the portion
The polarization direction of separated time polarised light is vertical with the absorption axis direction of upper polaroid, and therefore, which can project
Polaroid, so that pixel unit A and pixel unit B is shown in illuminated state.And the other parts of the liquid crystal across second area
The polarization direction of linearly polarized light is changed, though from the down polaroid of pixel unit A project linearly polarized light directive this penetrate
To the upper polaroid of pixel unit B, also due to the absorption axiss of the polarization direction of the other parts linearly polarized light and upper polaroid
And out of plumb, and pixel unit B can not be projected by upper polaroid absorption.Therefore, the light that each pixel unit is sent out be only from
The light that the down polaroid of the pixel unit projects avoids the luminous crosstalk of different pixels unit.If adjacent pixel unit institute
The color of the light sent out is different, then liquid crystal display panel provided in an embodiment of the present invention can send out to avoid adjacent pixel unit
Light colour contamination.
By taking liquid crystal display panel shown in FIG. 1 as an example, if pixel unit B is needed in dark when pixel unit A is shown in illuminated state
State is shown, then can apply voltage to the array substrate of pixel unit B, so that the liquid crystal in pixel unit B twists (such as
Torsion is shape shown in fig. 5).At this point, can be by picture from the polarization direction of the linearly polarized light of down polaroid directive pixel unit B
Liquid crystal in plain unit B changes so that the polarization direction of the linearly polarized light is parallel with the absorption axiss of upper polaroid, and then can not penetrate
Go out the upper polaroid of pixel unit B.In addition, the liquid for passing through second area from the linearly polarized light of down polaroid directive pixel unit A
The upper polaroid of brilliant directive pixel unit B, the liquid crystal of the second area can also make the polarization direction of the part linearly polarized light with
The absorption axis direction of upper polaroid is parallel, so that dull thread projects in pixel unit B, pixel unit B is shown in dark-state.
For another example in Fig. 2 and Fig. 4, which is the directions x, which is second area, this another
Region is first area.In fig. 2, the differently- oriented directivity of the first liquid crystal is the directions x, and the differently- oriented directivity of the second liquid crystal is perpendicular to paper
The direction (namely perpendicular to the directions x) in face, in Fig. 4, the differently- oriented directivity of the first liquid crystal is perpendicular to the direction of paper, the second liquid
Brilliant differently- oriented directivity is the directions x.For Fig. 2 liquid crystal display panels as shown in fig. 4, the absorption axiss of down polaroid can with it is upper partially
The absorption axiss of mating plate are vertical, and (assuming that the absorption axiss of down polaroid are parallel to the directions x, the absorption axiss of upper polaroid are perpendicular to paper
Direction).Fig. 2 liquid crystal display panels as shown in fig. 4 can be twisted-nematic (English：Twisted Nematic；Referred to as：
TN) the liquid crystal display panel of type.
Be also shown in Fig. 2 liquid crystal display panels as shown in fig. 4 pixel unit A in liquid crystal display panel and and its
Adjacent pixel unit B.If pixel unit A and pixel unit B is required to show in illuminated state, backlight becomes inclined by down polaroid
Direction shake for perpendicular to the linearly polarized light in the direction (that is to say the direction perpendicular to the directions x) of paper.Portion in the linearly polarized light
After separated time polarised light passes through the liquid crystal in pixel unit A and the liquid crystal in pixel unit B, the polarization direction of the part linearly polarized light
Become the directions x and project upper polaroid, so that pixel unit A and pixel unit B is shown in illuminated state.And pass through second area
Liquid crystal other parts linearly polarized light polarization direction still be perpendicular to the direction of paper, even if from pixel unit A it is lower partially
The upper polaroid for linearly polarized light directive directive pixel unit B that mating plate projects, also due to the other parts linearly polarized light
Polarization direction is parallel with the absorption axiss of upper polaroid, and can not project the upper polaroid of pixel unit B.Therefore, each pixel
The light that unit is sent out is the light only projected from the down polaroid of the pixel unit, avoids the luminous crosstalk of different pixels unit.
By taking liquid crystal display panel shown in Fig. 2 as an example, if pixel unit B is needed in dark when pixel unit A is shown in illuminated state
State is shown, then can apply voltage to the array substrate of pixel unit B, so that the liquid crystal in pixel unit B twists (such as
Torsion is shape shown in fig. 6).At this point, from down polaroid directive pixel unit B linearly polarized lights in by pixel unit B
Liquid crystal rear polarizer direction does not change so that the polarization direction of the linearly polarized light parallel with the absorption axiss of upper polaroid (is vertical
In the direction of paper), and then the upper polaroid of pixel unit B can not be projected.In addition, from down polaroid directive pixel unit A's
Linearly polarized light can also make this by the upper polaroid of the liquid crystal directive pixel unit B of second area, the liquid crystal of the second area
The polarization direction of part linearly polarized light is parallel with the absorption axis direction of upper polaroid, so that dull thread is penetrated in pixel unit B
Go out, pixel unit B is shown in dark-state.
