Patent ID: 7696529

Claim:
A transflective liquid crystal display device, comprising: a switching element on a substrate, the switching element including a gate electrode connected to a gate line, a source electrode connected to a data line, and a drain electrode, the data line and the source and drain electrodes are formed of the same metal; a first passivation layer formed over the switching element, the first passivation layer defining a drain electrode contact hole exposing a first portion the metal drain electrode; a transparent pixel electrode contacting the metal drain electrode through the drain electrode contact hole and defining a contact opening that exposes a second portion of the metal drain electrode, the contact opening being defined in a portion of the transparent pixel electrode in the drain electrode contact hole; and a reflective pixel electrode overlapping peripheries of the transparent pixel electrode, the reflective pixel electrode contacting the transparent pixel electrode in the drain electrode contact hole and contacting the metal drain electrode through the contact opening.
