Transflective liquid crystal display device having a thin film transistor and manufacturing method thereof

A transflective liquid crystal display (LCD) device having a thin film transistor, comprising:

• a device substrate having a reflection region and a transmission region;
• the thin film transistor formed on the reflection region of the device substrate and having a drain electrode;
• a passivation layer formed on the thin film transistor and exposing the drain electrode;
• a pixel electrode formed in a stacked structure comprising:
• a first pixel electrode electrically connected to the drain electrode;
• and
• a second pixel electrode formed to have an embossed pattern on the first pixel electrode;
• and
• a reflective layer formed on the second pixel electrode and formed in the reflection region of the device substrate,
• wherein a thickness of the second pixel electrode is greater than a thickness of the first pixel electrode.
