Abstract
A transflective liquid crystal display includes gate and data lines perpendicular to each other and defining a plurality of unit pixels. Each unit pixel includes a plurality of sub-pixel regions, which each have a transmissive portions and a reflective portion. The transmissive portions are gathered together within each unit pixel at corners of the sub-pixel regions opposing corners in which thin film transistors near the crossings of the gate and data lines are disposed. A passivation layer covering the thin film transistors and the gate and data lines has an opening that corresponds to the transmissive portions in the unit pixel. A reflector is formed over the passivation layer in each sub-pixel region and corresponds in position to the reflective portion. A pixel electrode in each sub-pixel region contacts the thin film transistor through a contact hole in the passivation layer.
