Abstract

The invention provides an array substrate, a manufacturing method thereof and a display panel, and relates to the technical field of display. The array substrate comprises a first transistor which is arranged on one side of an underlayment substrate and is located in a display area of the array substrate; a flat layer which covers the first transistor and is provided with a run-through first through hole; a first electrode layer which is arranged in the first through hole, is connected with the drain electrode in the first transistor, and is provided with a first groove; a filling layer which is arranged in the first groove; and a second electrode layer which is arranged on the side, away from the first transistor, of the filling layer, and is connected with the first electrode layer. According to the display panel, the filling layer is arranged in the first groove, so that the segment difference between the second electrode layer located on the filling layer and the second electrode layer located on the flat layer is reduced, an electric field for driving a liquid crystal layer is more uniform, the light leakage phenomenon of the display panel is reduced, a black matrix does not need to be arranged, and the aperture opening ratio of the display panel is increased.

Description

Technical field [0001] The present invention relates to the field of display, and in particular, to an array substrate and a method of fabricating a display panel. Background technique [0002] In the display panel, in order to achieve the driving of the liquid crystal molecules, the flat layer of the covering of the transistor is required to provide a through hole, and the connection of the pixel electrode to the drain of the transistor is achieved by the through hole. [0003] At present, the via hole is provided in the flat layer to connect the pixel electrode to the drain of the transistor, so that the display panel has leaked light, in order to improve the problem of leakage light of the display panel, a black matrix is ​​provided on the color film substrate or array substrate side. . [0004] However, in this manner of the black matrix, the black matrix will block the light transmitted through the array substrate, so that the opening rate of the display panel is lowered, wh...
