Abstract
An array substrate, a manufacture method thereof, and a liquid crystal display device (LCD) are provided. The array substrate includes a substrate; and a plurality of sub-pixel units disposed on the substrate. The sub-pixel unit comprises a thin film transistor (TFT), a pixel electrode, a common electrode and a passivation layer. The thin film transistor comprises an active layer, a gate electrode, a source electrode and a drain electrode. The drain electrode is electrically connected with the pixel electrode. The passivation layer covers the source electrode, the drain electrode and the pixel electrode. The sub-pixel unit further includes a test electrode which is electrically connected with the pixel electrode and is exposed at an external surface of the sub-pixel unit. With the test electrode, electrical characteristics of the TFT can be tested conveniently, and the quality level of the LCD device can also be improved.
