Taking the first region 13 of the four-domain pixel structure as an example, the tilt direction of the slits 12 in the first region 13 is the same as the tilt direction of the liquid crystal molecules 40 in the first region 13 after alignment, in other words, in this embodiment, the extending direction of the slits 12 of the pixel electrode 11 and/or the common electrode in the same domain is kept consistent with the alignment direction of the liquid crystal molecules 40, so that the liquid crystal molecules 40 are rotated under the combined action of the alignment film and the electric field of the slit electrodes until the tilt direction of the projection on the pixel electrode 11 or the common electrode (the extending direction of the long axis of the liquid crystal molecules 40 on the projection of the pixel electrode 11 or the common electrode) is the extending direction of the slits 12, the double-headed arrow a in fig. 5 is the tilt direction of the projection on the pixel electrode 11 after the liquid crystal molecules 40 are aligned, that is to ensure that all the liquid crystal molecules 40 are finally aligned to the preset alignment direction, thereby ensuring that all liquid crystal molecules rotate orderly, further improving the arrangement orderliness of the liquid crystal molecules 40 and improving the transmittance of the display panel, as shown in fig. 7.
The slit 12 may be provided in the pixel electrode 11 on the array substrate 20 side, the slit 12 may be provided in the common electrode on the counter substrate 30 side, or the slit 12 may be provided in both the pixel electrode 11 on the array substrate 20 side and the common electrode on the counter substrate 30 side.

The width of the slit 12 can be selected according to the actual requirement, and in the embodiment, the width of the slit 12 is 1-10 μm. The inclination angle of the slits 12 with respect to the row direction may be 45 ° or 135 ° to make the liquid crystal molecules 40 have a high transmittance after rotation, which contributes to further increase the transmittance of the display panel.

EXAMPLE III
On the basis of the first embodiment, the sub-pixel unit 10 or the pixel electrode 11 of the liquid crystal display panel provided in the present embodiment is divided into two regions, and fig. 10 is a schematic structural diagram of the pixel electrode of the liquid crystal display panel provided in the third embodiment. As shown in fig. 10, taking the pixel electrode 11 with the slit 12 as an example, the sub-pixel unit 10 or the pixel electrode 11 may be divided into a first region 13 and a second region 14 along the column direction or the row direction. The following description will specifically take as an example the sub-pixel unit 10 divided into the first region 13 located above and the second region 14 located below in the column direction.
It should be understood that the specific tilt direction of the slits 12 can be selected according to the specific alignment direction of the display panel, and it is sufficient to ensure that the tilt direction of the liquid crystal molecules 40 after alignment is consistent with the tilt direction of the slits 12, as shown by the double-headed arrow a in fig. 10, which is the tilt direction of the projection of the liquid crystal molecules 40 on the pixel electrode 11. The width of the slit 12 can be selected according to the actual requirement, and in the embodiment, the width of the slit 12 is 1-10 μm. The inclination angle of the slits 12 with respect to the row direction may be 45 ° or 135 ° to make the liquid crystal molecules 40 have a high transmittance after rotation, which contributes to further increase the transmittance of the display panel.
The inclination direction of the slits 12 in the first region 13 may be the same as the inclination direction of the slits 12 in the second region 14, or the inclination direction of the slits 12 in the first region 13 may be different from the inclination direction of the slits 12 in the second region 14, specifically, for example, the inclination direction of the slits 12 in the first region 13 may be the upward right direction, the inclination angle of the slits 12 is 45 °, the inclination direction of the slits 12 in the second region 14 may be the upward right direction, the inclination angle of the slits 12 is 45 °, or the inclination direction of the slits 12 in the second region 14 may be the upward left direction, and the inclination angle of the slits 12 is 135 °.
Specifically, as shown in fig. 10, the slits 12 in the first region 13 and the second region 14 are inclined in the same direction, and the inclination angle of the slits 12 in the first region 13 and the inclination angle of the slits 12 in the second region 14 are both 45 °. When the array substrate 20 and the opposite substrate 30 of the display panel are aligned, the array substrate 20 is aligned along the column direction, and the alignment directions of the entire array substrate 20 are the same, for example, the entire array substrate 20 is vertically downward along the column direction, the opposite substrate 30 is aligned along the row direction, and the alignment directions of the entire opposite substrate 30 are the same, for example, the entire opposite substrate 30 is horizontally rightward along the row direction, so that after the array substrate 20 and the opposite substrate 30 are aligned and stacked, the liquid crystal molecules 40 in the first region 13 and the second region 14 rotate at 45 ° after being aligned, and are parallel to the inclined direction of the slit 12, so that the liquid crystal molecules 40 are rotated by the joint action of the alignment film and the slit electrode, the arrangement order of the liquid crystal molecules 40 is effectively improved, and the transmittance of the display panel is improved, as shown in fig. 11.
In some examples, the slits 12 in the first region 13 and the second region 14 are inclined in directions perpendicular to each other, i.e., the sub-pixel unit 10 is two-domain, wherein the inclination angle of the slits 12 in the first region 13 is 45 °, and the inclination angle of the slits 12 in the second region 14 is 135 °. When the array substrate 20 and the opposite substrate 30 of the display panel are aligned, the array substrate 20 is aligned along the column direction, and the alignment direction of the whole array substrate 20 is the same, for example, the whole array substrate 20 is vertically downward along the column direction, the opposite substrate 30 is aligned along the row direction, the opposite substrate 30 is divided into a third part on the upper side and a fourth part on the lower side, wherein the alignment direction of the third part is leftward and the alignment direction of the fourth part is rightward, so that after the array substrate 20 and the opposite substrate 30 are overlapped in alignment, the liquid crystal molecules 40 in the first region 13 rotate 45 ° rightward after alignment, namely, the angle between the liquid crystal molecules 40 in the first region 13 and the row direction is 45 °, the angle between the liquid crystal molecules 40 in the second region 14 rotates 45 ° leftward after alignment, namely, the angle between the liquid crystal molecules 40 in the second region 14 and the row direction is 135 °, further, the liquid crystal molecules 40 in the first region 13 and the second region 14 are parallel to the tilt directions of the slits 12 in the regions.
Fig. 11 is a graph comparing the transmittance of a display panel with slits and the transmittance of a display panel without slits according to the third embodiment, in which the solid line represents the transmittance of the display panel with slits, and the dotted line represents the transmittance of the display panel without slits, as shown in fig. 11, in the present embodiment, the transmittance of the display panel with slits 12 on the pixel electrode 11 is improved by about 20% compared with the transmittance of the display panel without slits.
In the display panel provided by this embodiment, the sub-pixel unit 10 or the pixel electrode 11 is divided into two regions, and the alignment direction of the stacked alignment of the array substrate 20 and the counter substrate 30 is the same as the tilt direction of the slit 12, so that the tilt direction of the aligned liquid crystal molecules 40 in the two regions is parallel to the tilt direction of the slit 12, and the liquid crystal molecules 40 that previously pass only the alignment force of the alignment film but do not strictly follow the alignment direction can tilt according to the alignment direction under the action of the electric field of the slit electrode, thereby improving the arrangement of the liquid crystal molecules 40 and increasing the transmittance of the display panel.
