Abstract:
1. A method of manufacturing an array substrate of a transreflective LCD, comprising formation of a pre-preparing layer and formation of a post-preparing layer, wherein the formation of the pre-preparing layer comprises: a first patterning process of forming a first metal layer on a base substrate, coating a first photoresist layer on the first metal layer, exposing and developing the first photoresist layer with a full tone mask to form a first photoresist pattern, and performing etching by using the first photoresist pattern to form an embossing pattern in a reflective portion of a display region and to form a gate line; and a second patterning process of forming a first insulating layer, a semiconductor layer, an ohmic contact layer and a second metal layer sequentially on the substrate after the first patterning process, coating a second photoresist layer, exposing and developing the second photoresist layer with a first dual tone mask to form a second photoresist pattern, etching by using the second photoresist pattern to pattern the second metal layer to form a data line and to form a reflective plate in the reflective portion of the display region, ashing the second photoresist pattern and performing etching by using the remained photoresist pattern to form a thin film transistor (TFT) channel region, a source electrode connected with the data line and a drain electrode.
