Problems solved by technology

The total thickness of the multi-layer ink layer is large, and the height difference between the ink layer and the display panel is relatively large. If the thickness of the adhesive layer used is thin, it is easy to generate attachment bubbles during the attachment process of the display panel and the cover plate. , it is very easy to produce color cast when the display panel is lit
If the thickness of the adhesive layer is large, the cost of the adhesive layer will be increased, and the overall thickness of the display screen will become larger, which cannot meet the requirements of the thinning trend of the display device.
Moreover, the setting of the ink layer will reduce the amount of the adhesive layer located in the non-display area, which will affect the adhesion between the cover plate and the display panel, and cause the cover plate and the display panel to be easily peeled off.

Abstract

The invention discloses a display panel and a display device, which have a display area and a non-display area surrounding the display area, comprising: an array substrate and a polarizer located on one side of the array substrate; the polarizer includes at least one protective layer; At least one first ink layer, the first ink layer is located in the non-display area and surrounds the display area, and one first ink layer and any one of the protective layers are set on the same layer. Avoid air bubbles in the process of attaching the cover plate and display panel, avoid color shift of the display device during the display process, and prevent the ink layer from affecting the setting of the adhesive layer between the cover plate and the display panel, thus affecting the cover plate and display The bonding between the panels is also conducive to reducing the thickness of the adhesive layer, which is conducive to the requirements of the thinning trend of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In recent years, liquid crystal display devices or organic electroluminescent display devices, as mainstream products in flat panel display technology, have a wide range of applications, ranging from small consumer products such as mobile phones and digital cameras to large-scale products such as desktop computer monitors, televisions, and head-up displays. Displays are applied to every aspect of people's lives. [0003] Before leaving the factory, the cover plate in the display device is attached to the display panel through an adhesive layer. Usually, in order to prevent the light leakage of the display device, during the production process of the cover plate, multiple layers of light-shielding ink layers will be screen-printed on the cover plate. It is located on the part of the non-display ...
