Abstract

The invention discloses a thin film transistor, a liquid crystal display panel and a manufacturing method thereof. In the liquid crystal display panel, a transparent conductive layer is directly formed into a first electrode and a second electrode of the thin film transistor; and meanwhile, the transparent conductive layer is also used as a connecting line between the thin film transistor and a data line as well as between the thin film transistor and a liquid crystal capacitor. Thus, a contact window is not required to be additionally formed above the thin film transistor to provide a contact point, high flexibility can be provided in pixel design, and higher aperture opening ratio can also be provided.

Description

technical field [0001] The invention relates to the field of liquid crystal display panels, in particular to a thin film transistor using a transparent conductive layer directly as a source / drain electrode and electrically connected to a data line, a liquid crystal display panel with the thin film transistor and a manufacturing method of the liquid crystal display panel. Background technique [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products. Liquid crystal displays have gradually become widely used in various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. monitor with high resolution color screen. [0003] A liquid crystal display panel of a conventional liquid crystal display includes several pixels, and each pixel includes three pixel units representing three primary colors of red, green, and blue (RGB). ...
