Abstract

The invention discloses a display panel and a display device. The display panel comprises a first base plate and a second base plate, wherein the second base plate is arranged in a way of being opposite to the first base plate; the first base plate comprises scanning wires, data wires, a pixel electrode layer, a common electrode layer and a metal passing wire; the data wires and the scanning wires are distributed in a crossed way to form a plurality of pixel regions; the pixel electrode layer comprises pixel electrodes positioned in each pixel region; the common electrode layer comprises a plurality of common electrodes corresponding to the pixel regions; the metal passing wire is electrically connected with each common electrode, and comprises crossed metal passing wire rows and metal passing wire lines; the pixel regions comprise light transmission regions and non-light-transmission regions; the metal passing wire and the non-light-transmission region are overlapped. The metal passing wire arranged in the non-light-transmission region of the pixel region in the display panel can reduce the resistance of the common electrode; the delay time of a voltage signal on the common electrode is shortened; meanwhile, the influence cannot be caused on the transmission rate of the display panel; the aperture opening ratio cannot be reduced; the display quality of the display panel is improved.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to a display panel and a display device including the display panel. Background technique [0002] In recent years, liquid crystal display technology, as one of the mainstream display technologies, has been widely used in the display of televisions and mobile phones. Generally, a display panel in a liquid crystal device mainly includes a first substrate and a second substrate disposed opposite to each other, and a liquid crystal layer disposed between the first substrate and the second substrate. The above-mentioned first substrate may be an array substrate in a display panel. The first substrate mainly includes scan lines, data lines, pixel electrodes, and common electrodes, etc. The common electrode is usually made of transparent conductive indium tin oxide (ITO) material. Therefore, the resistance of the common electrode itself is relatively large. Therefore, when a common v...
