Abstract

The invention provides a display panel and a preparation method thereof. The display panel comprises a first metal layer and at least two metal oxide layers. The metal oxide layers are stacked on onesurface of the first metal layer. In the metal oxide layers, the content of oxygen atoms in metal oxide gradually decreases from the side away from the metal layer to the side close to the metal layer.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a display panel and a preparation method thereof. Background technique [0002] In the current large-size display panel products, especially the current hot 8K products, the conductive layer (such as the gate) in the TFT (Thin Film Transistor, thin film transistor) panel is generally made of Cu (copper) and other metals. However, the reflectance of visible light on the surface of the Cu film can reach up to 90%, and the Cu film is not shielded above. When the visible light reaches the surface of the Cu film, it will be reflected, resulting in high reflectance of the product and affecting the visual effect. [0003] Designing a low-reflectivity molybdenum oxide layer above or below the Cu film can reduce the reflectivity of the product and meet the needs of high-end products. However, molybdenum oxide has an amorphous structure and poor adhesion to Cu. Direct contact, after subsequ...
