Abstract
A method of fabricating a LCD device includes forming a gate line, a gate electrode, and a pixel electrode having a double-layer structure on a first substrate using a first mask, the double-layer structure including first and second conductive layers; forming a first insulation film, a semiconductor pattern on the first insulation film, a source/drain pattern having an upper storage electrode, source and drain electrodes, a data line using a second mask, the data and gate lines defining a pixel region having transmission and reflection areas; forming a second insulation film on the source/drain pattern and a transmission hole by passing through the second insulation film to the second conductive layer in the transmission area using a third mask; and forming a reflective electrode in the reflection area using a fourth mask, the reflective electrode connecting the pixel electrode with the drain electrode and the storage electrode.
