Array substrate for reflective type or transflective type liquid crystal display device

An array substrate for a liquid crystal display device, comprising:

• a substrate;
• a gate line and a data line on the substrate and crossing each other to define a pixel region;
• a thin film transistor connected to the gate line and the data line;
• a first passivation layer on the thin film transistor and having a first unevenness structure at its top surface;
• an auxiliary unevenness layer on the first passivation layer and having a first roughness structure at its top surface;
• and
• a reflector on the auxiliary unevenness layer, the reflector having a second unevenness structure due to the first unevenness structure of the first passivation layer and a second roughness structure due to the first roughness structure of the auxiliary unevenness layer, the second roughness structure having smaller patterns than the second unevenness structure,
• wherein the pixel region includes a reflective area and a transmissive area, the reflector and the auxiliary unevenness layer are disposed in the reflective area, a second passivation layer is formed on the reflector, and a pixel electrode is formed on the second passivation layer, wherein the pixel electrode corresponds to the reflective area and the transmissive area,
• wherein the second passivation layer and the first passivation layer have a drain contact hole exposing a drain electrode of the thin film transistor, and the pixel electrode is directly connected to the drain electrode through the drain contact hole.
