Abstract
A pixel substrate and a fabrication method thereof are provided. The method includes: forming a gate and a lower pad on a substrate; forming a gate insulating layer overlaying the gate and the lower pad; forming a channel layer and a first electrode layer on the gate insulating layer, in which the projection areas of the channel layer and the gate on the substrate are overlapped; forming an etching-barrier material layer on the substrate and simultaneously forming a contact opening at the gate insulating layer to expose the lower pad; forming a source, a drain and an upper pad on the substrate; forming a protective layer; forming a second electrode layer with multiple slits on the protective layer, in which one of the first and second electrode layers is electrically connected to the drain. The invention can simplify the process steps and reduce fabrication time.
