Abstract
A liquid crystal display includes a first substrate including a plurality of pixels, a second substrate facing the first substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. At least one of the pixels includes a thin film transistor disposed on a first insulating substrate, an insulating layer overlapping the thin film transistor, and a pixel electrode disposed on the insulating layer. A contact hole is formed through the insulating layer to expose a first electrode of the thin film transistor, the pixel electrode is electrically connected to the first electrode through the contact hole, and the pixel electrode has a single-layer in an area where the contact hole is formed and a double-layer on the insulating layer.
