Embodiment 1

[0027] An embodiment of the present invention provides a VA liquid crystal panel, which includes a plurality of sub-pixel units. like figure 2 and Figure 4 As shown, each sub-pixel unit includes a pixel electrode 101 and a common electrode 102 . Liquid crystal (not shown in the figure) is filled between the pixel electrode 101 and the common electrode 102, and the liquid crystal therein is aligned by UV2A technology.

[0028] In this embodiment, a slit-shaped opening 103 is opened on the pixel electrode 101 . figure 2 It is the first implementation mode in this embodiment, and the opening 103 is opened along the horizontal direction, and corresponds to the position of the dark lines in the horizontal direction in the "Swastika" dark lines. image 3 It is the simulation result of the transmittance displayed in the bright state. It can be seen that by setting the opening 103 in the horizontal direction, the degree of dark stripes in the horizontal direction is obviously re...

Embodiment 2

[0034] An embodiment of the present invention provides a VA liquid crystal panel, which includes a plurality of sub-pixel units, such as Figure 6 and Figure 7 As shown, each sub-pixel unit includes a pixel electrode 201 and a common electrode 202 . Liquid crystal (not shown in the figure) is filled between the pixel electrode 201 and the common electrode 202, and the liquid crystal therein is aligned by UV2A technology.

[0035] In this embodiment, a slit-shaped opening 203 is opened on the common electrode 202 . Figure 6 It is the first implementation mode in this embodiment, and the opening 203 is opened along the horizontal direction, and corresponds to the position of the dark lines in the horizontal direction in the dark lines of the "Swastika". By setting the opening 203 in the horizontal direction, the degree of dark stripes in the horizontal direction can be significantly reduced, and the simulation result of the transmittance of the bright state display is the sa...

Embodiment 3

[0041] An embodiment of the present invention provides a display device, which includes the VA liquid crystal panel provided in Embodiment 1 or Embodiment 2 above.

[0042] In addition, the above-mentioned embodiment 1 or embodiment 2 can also be combined with each other, that is, in a sub-pixel unit, both the pixel electrode and the common electrode are provided with slit-shaped openings, and the direction of the openings can be horizontal, vertical or horizontal. Any combination of straight direction and cross shape.

Abstract

The invention discloses a VA liquid crystal panel and a display device, and belongs to the technical field of display. The technical problem that an existing VA liquid crystal display is low in penetration rate is solved. The VA liquid crystal panel comprises a plurality of sub-pixel units. Each sub-pixel unit comprises a pixel electrode and a public electrode, wherein the pixel electrode or the public electrode is provided with a slit-shaped opening. The VA liquid crystal panel can be used for VA liquid crystal displays such as liquid crystal television sets and liquid crystal displays.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a VA liquid crystal panel and a display device. Background technique [0002] With the development of display technologies, liquid crystal displays have become the most common display devices. Among them, the Vertical Alignment (VA) liquid crystal display has become a mainstream product in the market because of its advantages of wide viewing angle and high contrast. [0003] At present, UV2A photo-alignment, as a new alignment technology, is widely used in the field of VA-type liquid crystal displays. The basic principle of UV2A technology is to coat a special alignment film that responds to ultraviolet rays on the glass substrate. When it is irradiated by ultraviolet rays, the alignment film will deflect along the irradiation direction, so that the liquid crystal molecules can be controlled with high precision. The angle and direction of the UV radiation is tilted. The VA-ty...
