摘要
A trans-reflective LCD and a manufacturing method thereof are provided to simplify a manufacturing process and improve yield by reducing the number of masks and implement high definition by preventing wavy noise. A first substrate divided into a pixel unit and first and second pad units is provided. Through a first mask process, a gate electrode and a gate line are formed in the pixel unit of the first substrate. Through a second mask process, an active pattern of an island type is formed on the gate electrode in a state when a first insulating layer is interposed. On the active pattern, an n+ amorphous silicon thin film pattern and a conductive layer pattern are formed. Through a third mask process, a source electrode and a drain electrode are formed in the pixel unit of the first substrate. A data line crosses the gate line to define a pixel area comprising a reflection unit and a transmission unit. Through the third mask process, a pixel electrode comprising a transparent conductive layer is formed in the transmission unit of the pixel area. Through a fourth mask process, a second insulating layer is formed on the first substrate. Through a fifth process, a reflection electrode comprising an opaque conductive layer is formed in the reflection unit of the pixel area. The first substrate is deposited with a second substrate.
