Abstract

The invention discloses an array substrate, a display panel and an array substrate manufacturing method. The array substrate includes a plurality of pixel units; each pixel unit includes a thin film transistor, a transparent conductive metal layer and a pixel electrode; and the thin film transistor includes a grid electrode, an active layer, a source electrode and a drain electrode, wherein the active layer is located above or below the grid electrode, and contacted with the transparent conductive metal layer in a stacked manner, the source electrode and the drain electrode form a channel of the active layer, and the drain electrode is connected to the pixel electrode. According to the invention, as the transparent conductive metal and the active layer are contacted in a stacked manner, a pixel electrode pattern and an active layer pattern can be formed only by performing half-tone mask patterning process at once after a transparent conductive thin film and an active layer film are deposited during manufacturing the array substrate, so that the production process is greatly simplified, the potential product defects brought by the mask patterning process are reduced at the same time, thereby greatly improving the production capacity.

Description

technical field [0001] The invention relates to the technical field of thin film transistor liquid crystal display, in particular to an array substrate, a display panel and a manufacturing method of the array substrate. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, etc., and occupies a dominant position in the current flat panel display market. leading position. [0003] At present, the display modes of TFT-LCD mainly include TN (Twisted Nematic, twisted nematic) mode, VA (Vertical Alignment, vertical orientation) mode, IPS (In-Plane-Switching, plane direction conversion) mode and AD-SDS (ADvanced Super Dimension Switch, advanced ultra-dimensional field switching technology, referred to as ADS) mode, etc. [0004] Among them, the ADS mode liquid crystal display mainly forms a mult...
