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.

Description

[0001] This application claims to enjoy the rights and interests of the Korean Patent Application No. P2004-41139 filed on June 5, 2004, and the entire contents of which are incorporated herein by reference. Technical field [0002] The present invention relates to a transflective thin film transistor substrate of a liquid crystal display device, in particular to a transflective thin film transistor substrate suitable for simplifying the process and a manufacturing method thereof. Background technique [0003] Generally, liquid crystal display (LCD) devices are classified into two types: a transmissive type, in which an image is displayed using light from a backlight unit, and a reflective type, in which an image is displayed using external light such as natural light. The disadvantage of the transmissive type is that the backlight unit has high power consumption, while the reflective type relies on external light so it cannot display images in a dark environment. [0004] To solv...
