Display panel and display device

A display device, comprising:

• a display panel, comprising:
• a display region, an array substrate, a color film substrate opposite to the array substrate, and a liquid crystal layer between the array substrate and the color film substrate, wherein:
• the display region includes transmissive regions each including color sub-pixels, and reflective regions each including black-and-white sub-pixels;
• a first common electrode is configured in the color film substrate corresponding to all of the transmissive regions and the reflective regions;
• a plurality of first pixel electrodes is configured spaced apart from one another and in a portion of the array substrate corresponding to the transmissive regions, and the plurality of the first pixel electrodes correspond to the color sub-pixels;
• a plurality of second pixel electrodes, a reflective layer and a plurality of first thin-film transistors are configured in a portion of the array substrate corresponding to the reflective regions, and the plurality of the second pixel electrodes correspond to the black-and-white sub-pixels;
• the reflective layer is at a side of the plurality of the second pixel electrodes adjacent to the liquid crystal layer;
• the plurality of the thin-film transistors is at a side of the plurality of the second pixel electrodes away from the liquid crystal layer;
• and one first thin-film transistor is electrically connected to one first pixel electrode;
• and
• a second common electrode is configured in the array substrate corresponding to all of the transmissive regions and the reflective regions;
• along a direction perpendicular to the array substrate, the second common electrode is between a first thin-film transistor and a second pixel electrode;
• and the second common electrode and the first common electrode is configured to receive a same voltage signal.
