Patent ID: 7773194

Claim:
A liquid crystal display device, comprising a first substrate with thin-film transistor arranged for each of a plurality of pixels in matrix arrangement, a second substrate where color filters with a plurality of colors formed to match the pixels and a light shielding film and a counter electrode are arranged, and a liquid crystal display panel prepared by attaching said first substrate and said second substrate and by sealing a liquid crystal between said substrates, wherein there are provided on said first substrate: a gate line where a gate electrode of said thin-film transistor is arranged on a part thereof and a scan signal is applied; a gate insulator film formed to cover said gate line; a semiconductor layer formed in island-like shape on said gate insulator film and constituting an active layer of said thin-film transistor; a source electrode and a drain electrode provided on said gate insulator film and connected to said semiconductor layer; a data line for preparing said source electrode on a part thereof and for supplying a display signal; and a pixel electrode connected to said drain electrode; said gate line and said gate electrode, said source electrode and said drain electrode, and said pixel electrode are formed by baking a conductive solution coated on a region enclosed by bank-like members of insulator film by ink jet method; and said bank-like members of the insulator film are arranged only in the region of said light shielding film on said second substrate.
