Patent ID: 7932963

Claim:
A substrate for a liquid crystal display device, comprising: pixel regions arranged in a matrix form on a base substrate; a pixel electrode formed in each of the pixel regions; a plurality of gate bus lines formed on the base substrate in parallel with each other and in each of which plural formation materials are laminated and at least a lower layer part is formed of a same formation material as the pixel electrode; a plurality of drain bus lines intersecting with the gate bus lines through an insulating film and formed to be in parallel with each other; a thin film transistor formed in each of the pixel regions and including a gate electrode connected to the gate bus line, a drain electrode connected to the drain bus line and a source electrode connected to the pixel electrode; a protection film formed on the thin film transistor; a plurality of gate bus line terminals respectively connected to the plurality of gate bus lines; and a plurality of drain bus line terminals respectively connected to the plurality of drain bus lines; wherein holes are opened in the protection film at least at parts of the gate bus line terminals and at least at parts of the drain bus line terminals.
