  • 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.

  • Patent number: 11906861
    Abstract: Provided are a display panel and a display device. The display panel includes multiple data lines and multiple scanning lines. The multiple data lines intersect with the multiple scanning lines to define multiple pixel units arranged in an array, and the data lines are insulated from the scanning lines; and pixel electrodes of pixel units that are among the multiple pixel units and in at least portion of the array include multiple first branch electrodes arranged in parallel; along a direction of the multiple scanning lines, each of the multiple first branch electrodes includes multiple first branch electrode segments connected sequentially; and an included angle between two adjacently connected first branch electrode segments of the multiple first branch electrode segments is less than 180°.
