Abstract
A liquid crystal display device, and a manufacturing method thereof, having an existing box-like counter electrode connected to the source/drain electrode through a first contact hole in the gate insulating film and so is used as the pixel electrode, and the existing slit-shaped counter electrode is connected to the non-transparent metallic common bus line through a second contact hole in the gate insulating film and so becomes the counter electrode while maintaining the existing process layer structure as it is, so that even if a short circuit occurs between the gate bus line and the pixel electrode in the same layer due to the particle, degradation is limited to only one pixel, which results in enhancing of the process yield.
