Abstract

The invention discloses a display panel and a display device and aims at improving the flatness of the whole display panel, preventing a non-display zone from being too high or too low compared with a display zone, accordingly relieving or avoiding the phenomenon that the peripheral edge of a display picture yellows or becomes whitish and ensuring package impermeability. The display panel comprises a display zone and a non-display zone, wherein black matrixes, colorful film layers and spacers are arranged in the display zone and the non-display zone, projections of the black matrixes, the colorful film layer and the spacer in the non-display zone have overlapped zones in the direction perpendicular to the display panel, and the difference between the height sum of the black matrixes, the colorful film layers and the spacers in the overlapped zones and the height sum of the colorful film layer and the spacers in the display zone is smaller than a preset threshold value.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] see figure 1 At present, liquid crystal display (Liquid Crystal Display, LCD) products include a display area (Active Area, AA) and a non-display area, wherein the non-display area includes the peripheral area of ​​the display area (AA~Sealant, which can also be called the Dummy area) and packaging (Sealant) area, the Sealant area is the area corresponding to the sealant 03, the AA~Sealant area is the area between the area where the sealant is located (Sealant area) and the AA area, and the sealant 03 is used for The array substrate 01 and the color filter substrate 02 are box-packaged. At present, the frame of TPC (Tablet PC) products is relatively large, the frame width is about 1.7mm, the width of the Sealant area is about 0.5mm, and the width of the AA~Sealant area is generally about 1.3mm. [0...
