  • Patent number: 11927856
    Abstract: A display panel and a display device are provided according to embodiments of the application. In the display panel, a first metal electrode layer further includes multiple second metal electrode lines which are located in the same layer as multiple first metal electrode lines. An end of the second metal electrode line is electrically connected with the drain of a thin film transistor; and the other end of the second metal electrode line is electrically connected with the pixel electrode, so that the pixel electrode is electrically connected with the drain of the corresponding thin film transistor through the second metal electrode line. The area occupied by the electric connection region of the pixel electrode and the drain of the corresponding thin film transistor is reduced and the display area of the display panel is increased, when the size and the thickness of the display panel are not increased.
