Display panel and display device

A display device comprising:

• a display panel, comprising a first pixel area and a second pixel area adjacent to the first pixel area, wherein the display panel comprises an array substrate, a color film substrate arranged oppositely to the array substrate, a liquid crystal layer between the array substrate and the color film substrate, and a backlight module positioned at a side of the color film substrate, wherein the side of the color film is facing away the array substrate;
• wherein, the display panel comprises a plurality of micro light emitting diode (micro LED) lighting units, a transparent area is placed among the micro LED lighting units, and the color film substrate comprises a color filter in the second pixel area;
• wherein the micro LED lighting units are located in the first pixel area and between the array substrate and the backlight module, and the backlight module has a hollow region substantially corresponding to the first pixel area, and
• wherein each of the micro LED lighting units comprises an electrode surface facing the hollow region of the backlight module, and the electrode surface has a first electrode,
• wherein each of the micro LED lighting units further comprises a substrate surface opposite to the electrode surface, and a lighting direction of the micro LED lighting unit is from the electrode surface to the substrate surface,
• wherein the array substrate comprises a second substrate;
• the micro LED lighting units are corresponding to the first pixel area and placed on a side of the second substrate, which is close to the color film substrate, and
• wherein a second electrode corresponding to the first electrode is placed on a position of the second substrate, which corresponds to the first pixel area;
• and the first electrode is electrically connected to the second electrode.
