Abstract

The present application proposes a display panel and a display device. The display panel includes a first substrate and a second substrate oppositely arranged, and the first substrate includes a substrate, a light-shielding layer arranged on the substrate, and a The first insulating layer on the substrate and the light-shielding layer and covering the light-shielding layer, the source-drain metal layer disposed on the first insulating layer; the orthographic projection of the light-shielding layer on the substrate The orthographic projection of the source-drain metal layer on the substrate is covered by setting a light-shielding layer on the substrate, and the orthographic projection of the light-shielding layer on the substrate covers the source-drain metal layer on the substrate. For the orthographic projection on the bottom, the source-drain metal layer is shielded by the light-shielding layer, preventing the concave structure on the side of the source-drain metal layer from being irradiated by light from the backlight source and affecting the display uniformity of the display panel.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] LCD (Liquid crystal displays, liquid crystal display) is a widely used flat panel display, which mainly realizes picture display by modulating the light field intensity of the backlight source through liquid crystal switches. [0003] At present, the source-drain metal layer where the source-drain is located in the display panel usually adopts a stacked composite structure of Ti titanium / Al aluminum / Ti titanium. Since aluminum is easier to be etched than titanium, during the manufacturing process, the side surface of the source-drain metal layer The aluminum layer in the middle is etched too much, and a concave structure is formed on the side of the source-drain metal layer. When the light from the backlight irradiates the concave structure, diffuse reflection will occur. The uniformity of the reflected light is poo...
