Abstract:
1. A method of manufacturing a liquid crystal display device, comprising: sequentially forming silicon and a first metal material over a substrate; forming a first silicon pattern, and a stack of a second silicon pattern and a storage line formed to contact the second silicon pattern using a diffraction mask; forming a first insulating layer on the substrate including the first silicon pattern, and the stack of the second silicon pattern and the storage line; forming a second metal material on the substrate and patterning the second metal material to concurrently form a gate electrode, a pixel electrode, and a connection line; performing ion implantation on the first silicon pattern to form an active layer; forming a second insulating layer including a plurality of contact holes for exposing the first active layer, the gate electrode, the pixel electrode, and the connection line; and forming a third metal material over the second insulating layer and patterning the third metal material to form a gate line connected to the gate electrode, source and drain electrodes connected to the active layer, and a data line connected to the connection line.
