Transflective liquid crystal display device and manufacturing method thereof

1. A liquid crystal display device, comprising:

first and second substrates facing each other;

a gate line and a data line on the first substrate, the gate and data lines intersecting each other and defining a pixel region having a transmissive region and a reflective region;

a thin film transistor on the first substrate at an intersection between the gate line and the data line;

a pixel electrode in the pixel region of the first substrate connected to the thin film transistor;

an organic insulating layer includes an uneven pattern in the reflective region on the second substrate, the organic insulating layer including a through-hole in the transmissive region;

a reflective electrode on the second substrate corresponding to the organic insulating layer in the reflective region;

a black matrix on the reflective electrode of the second substrate corresponding to the thin film transistor of the first substrate and a boundary region between adjacent pixel regions;

a color filter layer on the reflective electrode in the reflective region and the second substrate in the reflective region and the transmission region; and

a liquid crystal layer between the first and second substrates,

wherein a first gap between the first and second substrates in the transmissive region is larger than a second gap in the first and second substrates in the reflective region.

2. The device according to claim 1 , wherein the uneven pattern includes at least one groove.

3. The device according to claim 1 , further comprising a common electrode on the color filter layer.

4. The device according to claim 1 , wherein the color filter layer contacts the second substrate via the through-hole in the transmissive region.

5. The device according to claim 1 , further comprising a light source, light generated by the light source incident onto a bottom surface of the second substrate.
