Abstract
This application discloses a display panel (100) and a display device (600). The display panel (100) includes: a plurality of scan lines (111); a plurality of data lines (112); a color filter (400) formed in a display area (110); and a dummy color filter (410) formed in a non-display area (113). The dummy color filter (410) includes a first dummy color filter (411) and a second dummy color filter (412). The first dummy color filter (411) is located on a first side edge (120) of the non-display area (110) and is arranged perpendicular to the scan lines (111). The first dummy color filter (411) has openings.
