Embodiment Construction

[0030] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited thereto.

Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate and a liquid crystal layer arranged between the first substrate and the second substrate, a plurality of pixel electrodes are arranged on the side, facing the second substrate, of the first substrate in an array mode, a gap is formed between every two adjacent pixel electrodes, and a plurality of shading electrodes and the pixel electrodes are arranged on the same layer. Each shading electrode is correspondingly arranged in the corresponding interval, the common electrode is arranged on the side, facing the first substrate, of the second substrate, and an electric field is formed between the common electrode and the corresponding shading electrode. The holes are formed in the common electrodes corresponding to the shading electrodes or the preset voltage on the shading electrodes is adjusted to be different from the voltage on the common electrodes, so that a vertical electric field is formed between the common electrodes and the corresponding shading electrodes, transverse movement of foreign ions is hindered, and the problem that line residues exist in an existing LCD panel is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of liquid crystal display (Liquid Crystal Display, LCD) technology, in order to achieve high resolution, the number of pixels (Pixel) in the LCD panel is increasing and the pixel size is getting smaller and smaller, so that the electric field density will also increase accordingly. . At the same time, consumers have higher and higher requirements for the display quality of LCD products. For this reason, various manufacturers will conduct a series of reliability tests on LCD panels. ). Ordinary afterimage means that the LCD panel maintains a fixed grayscale image for a long time, and after switching to other grayscale images, the previous image will be retained. This phenomenon is called afterimage. But when clicking on the black and white checkerboard, a light line will appear a...
