Abstract:
1. A method of fabricating an array substrate for a liquid crystal display device, the steps comprising: forming a gate line and a data line on a substrate, the gate line and the data line crossing each other to define a pixel region; forming a thin film transistor connected to the gate line and the data line; forming a first passivation layer on the thin film transistor and having a first unevenness structure at its top surface; forming an auxiliary unevenness layer on the first passivation layer and having a first roughness structure at its top surface; and forming 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 second unevenness structure of the reflector includes concave portions and convex portions, and each of the concave portions and the convex portions includes the second roughness structure, wherein the first passivation layer and the auxiliary unevenness layer have a contact hole exposing an electrode of the thin film transistor, and the reflector is directly connected to the electrode through the contact hole.
