The application provides a pixel electrode which is used on a display panel, in particular on an array substrate of the display panel.

In one embodiment:

referring to fig. 1 and fig. 2, the present application provides a pixel electrode 10, where the pixel electrode 10 at least includes:

the pixel electrode comprises a first slit 20, a second slit 30 and a third slit 40, wherein the second slit 30 and the third slit 40 are arranged in parallel and at intervals, and the first slit 20 is vertically arranged on the second slit 30 and the third slit 40 to divide the pixel electrode 10 into a plurality of sub-pixel regions 101.

The pixel electrode 10 is made of a transparent conductive film, and in the liquid crystal display panel, the pixel electrode 10 is used to store charges from the data line, and belongs to a planar film. In order to make the lcd panel have higher contrast and wider viewing angle, each pixel is divided into a plurality of alignment regions, and the alignment regions control the alignment direction of the liquid crystal molecules. The pixel electrode is provided with a plurality of molecular pixel electrodes 10 extending along different directions, so that under the condition that voltages are applied to liquid crystal molecules in different alignment regions, the liquid crystal molecules can incline towards different directions to change the visual angle and color cast. Since the liquid crystal is a continuum, many places where the liquid crystal is not aligned continuously will be present at the intersecting position of the branch pixel electrodes 10 extending in different directions, so the present application arranges at least a first slit 20, a second slit 30 and a third slit on the pixel electrode 10, and the regions separated by the slits become different alignment regions (branch pixel electrodes 10), so under the condition of applying voltage to the liquid crystal molecules in different alignment regions, the intersecting position of the branch pixel electrodes 10 is a slit, and the slit is a hollow structure, there is no transparent conductive particle in the slit, and the liquid crystal will not be aligned in the intersecting position and disconnected, so that the liquid crystal efficiency will not be decreased.

Furthermore, based on the arrangement relationship of the first slit 20, the second slit 30 and the third slit 40, if the first slit 20 is vertically disposed on the second slit 30 and the third slit 40 to divide the pixel electrode 10 into a plurality of sub-pixel regions 101, the plurality of sub-pixel regions 101 may be disposed with a plurality of alignment regions, and after applying pressure on the plurality of alignment regions, the liquid crystal molecules may be inclined in more directions, so as to greatly improve the display viewing angle and reduce the color shift problem.

Therefore, in the present application, at least the first slit 20, the second slit 30 and the third slit 40 are disposed on the pixel electrode 10 to form a plurality of sub-pixel regions 101, and due to the arrangement of the slit hollow structure, the liquid crystal does not have a situation that the efficiency of the liquid crystal is reduced due to the fact that the liquid crystal is not connected in the arrangement at the intersection position of different sub-pixel regions 101, and due to the fact that the first slit 20 is vertically disposed on the second slit 30 and the third slit 40, the pixel electrode 10 is divided into the plurality of sub-pixel regions 101, so that the alignment of the liquid crystal is increased, the inclination direction of liquid crystal molecules is increased, the display viewing angle is improved, and the color cast is reduced.

Further, the pixel electrode 10 further includes a fourth slit 50, the fourth slit 50 is parallel to the second slit 30 and the third slit 40 and is arranged at an interval, and the first slit 20 is vertically disposed on the second slit 30, the third slit 40 and the fourth slit 50 to form a "full" shaped slit on the pixel electrode 10, so that the pixel electrode 10 is divided into eight sub-pixel regions 101.

The first slit 20 is vertically disposed on the second slit 30, the third slit 40 and the fourth slit 50, and is communicated with the second slit 30, the third slit 40 and the fourth slit 50, so that a hollow structure in a shape of Chinese character feng is formed at a middle position of the pixel electrode 10. The liquid crystal molecules at the corresponding positions of the full-page-shaped structure are not inclined, and the liquid crystal molecules at the crossed positions of the two adjacent sub-pixel areas 101 are not inclined, so that the situation that the liquid crystal arrangement is discontinuous is avoided, and because the full-page-shaped structure can uniformly divide the areas of the sub-pixel areas 101 on the pixel electrode 10, the display visual angle is enlarged, meanwhile, the pictures seen from all angles on the display panel can be ensured to be consistent, and the display effect of the display panel is improved.

More specifically, the first slit 20, the second slit 30, the third slit 40, and the fourth slit 50 are located in a middle region of the pixel electrode 10, wherein the first slit 20 divides the pixel electrode 10 into two sub-pixel regions 101; the second slit 30, the third slit 40 and the fourth slit 50 divide the two sub-pixel regions 101 into eight sub-pixel regions 101. The gap between the second slit 30 and the third slit 40 is equal to the gap between the third slit 40 and the fourth slit 50. In this way, the first slit 20 divides the pixel electrode 10 into two sub-pixel regions 101 with the same area, and the second slit 30, the third slit 40 and the fourth slit 50 divide the two sub-pixel regions 101 with the same area into eight sub-pixel regions 101 with the same area. Since the areas of the sub-pixel electrodes 10 are equal, the light transmittances are the same, and the uniformity of the display effect of each display region of the display panel is further ensured.
