Abstract:
1. A liquid crystal display device comprising: a pair of substrates which face each other in an opposed manner while sandwiching liquid crystal therebetween; a plurality of gate signal lines arranged in parallel and a plurality of drain signal lines arranged in parallel while crossing the respective gate signal lines; a plurality of pixel regions each surrounded by a pair of the gate signal lines and a pair of the drain signal lines; a plurality of thin film transistors each driven by a scanning signal supplied from one of the pair of gate signal lines, and a plurality of pixel electrodes each receiving a video signal from one of the pair of drain signal lines through a respective thin film transistor formed in a pixel region thereof, wherein said respective thin film transistor includes a drain electrode connected to said one of the drain signal lines, a source electrode electrically connected to said one of the pixel electrodes thorough a contact hole and spaced from said one of the drain signal lines, and said one of the pixel electrodes has a projection portion projecting towards a neighboring gate signal line of said one of the gate signal lines, said projecting portion has an overlapping region overlapping with the neighboring gate signal line of said one of the gate signal lines, a conductive layer is formed between the gate signal line and the projection portion of the pixel electrode, and the conductive layer is electrically connected with said one of the pixel electrodes through a contact hole, a columnar spacer, which is arranged to overlap with the conductive layer, has a width wider than a width of the contact hole.
