Abstract
The invention provides an array substrate and a manufacturing method thereof. The manufacturing method comprises the steps of: manufacturing a switch array layer on a substrate; forming a color resistance layer on the switch array layer, wherein the color resistance layer comprises a red color film, a green color film and a blue color film, and via holes are formed in the color resistance layer; forming a transparent conductive layer on the color resistance layer; and forming a light-shielding layer on the transparent conductive layer. According to the array substrate and the manufacturing method thereof, a black matrix is manufactured after manufacturing the transparent conductive layer, so as to prevent hole size deviation which is prone to occur when forming the via holes in the black matrix and the color resistance layer, and prevent the transparent conductive layer from fracturing.
Description
【Technical field】 [0001] The invention relates to the technical field of liquid crystal displays, in particular to an array substrate and a manufacturing method thereof. 【Background technique】 [0002] Such as figure 1 As shown, the existing array substrate: for example, it is a BOA (BMonArray) substrate. The BOA substrate is to make a color filter film and a black matrix on the array substrate. The array substrate includes: a base substrate 11, a first metal layer 12 located on the substrate On the substrate 11, including the gate; the gate insulating layer 13 is partly located on the first metal layer 12, for isolating the first metal layer 12 and the active layer 14; the active layer 14 is partly located on the gate insulating layer 13, for To form a channel; the second metal layer 15 is located on the active layer 14, including source and drain; the second insulating layer 16 is located on the second metal layer 15; the color resistance layer 17 is located on the second...
