Abstract
The present invention relates to a transflective thin film transistor substrate and method of fabricating the same that is adaptive for simplifying its process. The liquid crystal display device includes: first and second substrates; a gate line on the first substrate; a gate insulating film on the first substrate; a data line crossing the gate line to define a pixel area; a thin film transistor connected to the gate line and the data line; an organic insulating film on the gate line, the data line and the thin film transistor, and having a transmission hole in the pixel area; a pixel electrode on the organic insulating film of the pixel area via the transmission hole and connected to the thin film transistor; and a reflective electrode on the pixel electrode having a same edge part as the pixel electrode or an edge part located at inner side from an edge part of the pixel electrode and exposing the pixel electrode of the transmission hole.
