Abstract
A disclosed liquid crystal display includes a substrate with a gate electrode, a gate insulation film, an active layer, a source electrode, a drain electrode, and a first passivation film formed on the substrate. An organic insulation film having a first contact hole and a common electrode having a second contact hole are formed on the first passivation film using a single mask. The display also includes a second passivation film on the common electrode, and a pixel electrode on the second passivation film and connected to the drain electrode via the contact hole through the second passivation film. The top surface of the organic insulation film adjacent to a side edge of the organic insulation film is uncovered by the common electrode.
