ABSTRACT:
A manufacturing method of an array substrate for a liquid crystal display device includes forming a switching element in a pixel area on a substrate, wherein the pixel area includes a reflective area and a transmissive area, forming an organic layer on an entire surface of the substrate including the switching element, first exposing the organic layer using a first mask, second exposing the first exposed organic layer using a second mask, developing the first and second exposed organic layer to form a passivation layer having an unevenness pattern in the reflective area, forming a reflector on the passivation layer in the reflective area, and forming a pixel electrode on the reflector in the reflective area and the transmissive area.
