Abstract
The invention discloses a display panel and a display device. The display panel comprises a substrate, a plurality of pixel units located on the substrate, a plurality of scanning lines and a plurality of data lines, wherein each pixel unit comprises at least one thin-film transistor; the substrate is provided with a reflective metal part; a first metal part and a second metal part are included between the reflective metal part and the substrate; the first metal part and a gate are arranged on the same layer; the second metal part is located between the first metal part and the reflective metal part and connected with common potential; the first metal part is connected with the common potential or floats; or the second metal part is located at one side, far away from the reflective metal part, of the first metal part; the first metal part is connected with the common potential; and the second metal part is connected with the common potential or floats. The display device comprises thedisplay panel. According to the display panel and the display device, the flatness of a reflecting area can be optimized, the reflecting contrast can be improved, light leakage can be avoided and a value of storage capacitance cannot exceed the required range, thereby not affecting the performance of the display panel.
Description
technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the continuous development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable tool for people today. . The important part of the display device to realize the display function is the display panel. According to different applications, the display panel is divided into a transmissive display panel, a reflective display panel and a transflective display panel. The transmissive display panel has the characteristics of high brightness and high color saturation, but consumes a lot of power, especially under strong light, and has the disadvantages of poor contrast and unvisible images. Reflective display panels have the advantages of low power co...
