Benefits of technology

This design ensures the pixel electrode can be charged normally by the drain electrode, thereby increasing the yield rate of liquid crystal display devices.

Problems solved by technology

Because the structure of a LTPS array substrate is complicated.
When manufacturing, an abnormal of incomplete through hole will generate on the insulation layer such that a charging to the pixel electrode from the drain electrode cannot be operate normally in order to affect the yield rate of the liquid crystal display.

Abstract

An array substrate and an LCD device are provided. The array substrate includes multiple LTPS thin-film transistors. Each transistor includes: a substrate; and a LTPS layer, a first insulation layer, a gate electrode, a second insulation layer, a source electrode, a drain electrode, a planarization layer, a first transparent conductive layer, a third insulation layer, a second transparent conductive layer and a connection metal layer. The LTPS layer, and gate electrode and the second insulation layer are sequentially disposed. The source electrode and the drain electrode are disposed on the second insulation layer, and connected with two terminals of the LTPS layer through the first and second through holes. The connection metal layer connects with the second transparent conductive layer and the drain electrode through a fourth through hole. The first transparent conductive layer is a common electrode and the second transparent conductive layer is a pixel electrode.
