Embodiment Construction

[0046] The technical solutions in the embodiments of the disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present disclosure.

[0047] With the continuous development of display technology, the performance requirements of liquid crystal displays are getting higher and higher, but there are still problems in the existing liquid crystal display devices, such as the large viewing angle and the relatively poor viewing angle, especially in the multi-domain design. structure display device. With the increase of the number of thin film transistors, the aperture ratio of the display panel is seriously lost, the light tr...

Abstract

Embodiments of the present disclosure provide a display panel and a display device. The display panel includes upper and lower substrates, a liquid crystal layer, a first electrode, and a second electrode, wherein the opposite second electrodes in each sub-image area further include at least one main electrode and A plurality of electrode branches, the main electrode divides the sub-pixel area into at least four liquid crystal domain areas, and at the same time, divides the sub-pixel area corresponding to each liquid crystal domain area, so that a gap is formed between the pixels, thereby increasing the display panel The number of liquid crystal domains increases the transmittance of light and improves the display quality.

Description

technical field [0001] The disclosure relates to the field of panel display technology, and in particular, to a display panel and a display device. Background technique [0002] A liquid crystal display (LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] At present, the polymer stabilized vertical alignment (PSVA) technology is commonly used in the vertical alignment mode of the commonly used liquid crystal display, which has the advantages of high contrast ratio and fast response speed. However, in the existing PSVA technology, it is necessary to use ultraviolet radiation in the box-making process. However, in this way, under the current pixel design framework, there must be a certain area around the pixel that is not ideal, and it is easy to form a dark area, which affects the display. Effect. At the same time, in the existing multi-domain pixel structure design, in order to increase the number of domains in t...
