Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel and a display device. Background technique [0002] With the development and progress of liquid crystal display technology, people have higher and higher requirements for liquid crystal display devices. At present, a display device that can be used as a mirror and as a display is very popular, that is, a mirror display device. [0003] The preparation of existing mirror display devices usually adopts a layer of semi-reflective and semi-permeable film on the outgoing light of the display panel. When displaying, the light from the backlight passes through the display panel to form a color picture for display; when the display is completed Finally, at this time, the light from the external environment is irradiated on the semi-reflective and semi-transparent film to realize the mirror display. [0004] The matching of photoelectric characteristics bet...
