Abstract
The present invention provides a liquid crystal display device with high brightness and high display quality manufactured at low cost without causing the decrease in transmissivity. The liquid crystal display device comprises a gate line GL with a gate electrode GT of thin-film transistor prepared on a first substrate SUB1 and used for applying a scan signal, a gate insulator film GI deposited to cover the gate line, a semiconductor layer nS/S formed in island-like shape on the gate insulator film and to constitute an active layer of the thin-film transistor, a source electrode SD1 and a drain electrode SD2 arranged on the gate insulator film and individually connected to said semiconductor layer, and a pixel electrode PX connected to the drain electrode SD2 wherein the gate line GL and the gate electrode GT, the source electrode SD1, the drain electrode SD2, and the pixel electrode PX are prepared by ink jet coating of a conductive solution in a region enclosed by banks G-BNK, SD-BNK, and P-BNK of the insulator film and by baking. Each of these banks is arranged only in a region where it is concealed by the light shielding film BM on the second substrate SUB2.
