Abstract
The present invention provides an array substrate, and adds a floating electrode layer in a contact hole for realizing an electrical connection between a metal layer of a TFT and a pixel electrode layer such that the pixel electrode layer is electrically connected to the metal layer through a bridging of the floating layer so as to decrease a resistance value and decrease the film-breaking probability of the pixel electrode layer in the contact hole. Besides, an edge of the floating electrode layer is located in the contact hole so as to reduce a size of a black matrix, increase a pixel aperture ratio. The present invention also provides a method for manufacturing the array substrate and a liquid crystal display panel having the array substrate.
