Title
(EN) Array substrate, manufacturing method thereof and wide-viewing angle liquid crystal display
(ZH) 阵列基板及其制造方法和宽视角液晶显示器
Abstract
(EN)
The invention relates to an array substrate, a manufacturing method thereof and a wide-viewing angle liquid crystal display. The array substrate comprises a substrate, a plurality of pixel areas and an organic transparent insulating layer, wherein the organic transparent insulating layer is formed between a passivation layer and a pixel electrode. The manufacturing method comprises the following steps of: forming a public electrode, a public electrode wire and patterns of a thin film transistor switch on the substrate; depositing the passivation layer; forming the organic transparent insulating layer, an organic layer via hole and a passivation layer via hole on the passivation layer; and forming patterns of the pixel electrode on the organic transparent insulating layer, wherein a plurality of gaps are formed on the patterns of the pixel electrode, and the pixel electrode is connected with the thin film transistor switch through the organic layer via hole and the passivation layer via hole. A liquid crystal display of the invention comprises the array substrate. In the array substrate, the technical means of adding the organic transparent insulating layer between the pixel electrode and the passivation layer is adopted to increase the thickness of film layers between the pixel electrode and the public electrode, so that the storage capacitance and residual images can be reduced effectively.
