Array substrate, manufacturing method thereof and display panel

Abstract

The embodiment of the invention discloses an array substrate, a manufacturing method thereof and a display panel. The array substrate comprises a substrate, and a first planarization layer, a first conductive layer and a second planarization layer which are positioned on the substrate. The first planarization layer is located between the substrate and the second planarization layer; the first conductive layer is located between the first planarization layer and the second planarization layer; a first groove is formed in one side, close to the second planarization layer, of the first planarization layer; the first conductive layer is partially or completely located in the first groove, so that the flatness of the side, away from the substrate, of the first conductive layer and the flatness of the side, away from the substrate, of the first planarization layer are improved. According to the technical scheme provided by the embodiment of the invention, the planarization effect can be improved, the thickness of the planarization layer is reduced, and the planarization effect does not depend on the thickness of the planarization layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] In an actively driven display device, in order to realize active driving, a Low Temperature Poly-Silicon (LTPS for short) array substrate design is currently used. [0003] The LTPS array is formed by patterning and stacking different functional layers, and the flattening ability of the flattening layer in the array film layer is limited, that is, the flat organic glue has certain fluidity and viscosity, and will flow down, but it cannot make the pits and the protrusions are completely leveled, resulting in thickness fluctuations of the array substrate under the pixel area. In the prior art, the planarization effect is improved by increasing the thickness of the planarization layer, which will increase the thickness of the screen body. Contents of the invention [0...
