Abstract

See full text

A liquid crystal display device is provided that includes: first and second substrate; a gate line of a double layer having a first transparent conductive layer and a second opaque conductive layer on the first substrate; a first insulation layer on the gate line; a data line crossing the gate line to define a pixel region, the pixel region having a transmissive region and a reflective region; a thin film transistor connected to the gate and data lines; a pixel electrode formed of the transparent conductive layer in the pixel region; an upper storage electrode forming a storage capacitor by overlapping the gate line with the gate insulating film there between; a transmission hole to exposing the pixel electrode by passing through a second insulation layer on the thin film transistor to the first insulation layer; a reflective electrode connecting the pixel electrode with a drain electrode and the upper storage electrode through an edge part of the transmission hole; a gate pad extending from the first conductive layer of the gate line; a data pad formed of the first conductive layer and connected to the data line through a data link; and a liquid crystal layer between the first and second substrates, wherein the first and second insulation layers are removed in the gate and data pads.
