Abstract
A liquid crystal display device comprises a pair of substrates which are arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, pixel regions which are formed on a liquid-crystal-side surface of one substrate out of the pair of substrates, and thin film transistors which are formed on respective pixel regions, wherein each thin film transistor includes a gate electrode connected to a gate signal line, a semiconductor layer laminated to the gate electrode by way of an insulation film, a drain electrode formed on the semiconductor layer and connected to a drain signal line, and a source electrode connected to a pixel electrode, and the semiconductor layer is formed in a periodically irregular shape in a zone having a width substantially larger than a width of the source electrode on a side thereof from which at least the source electrode is pulled out.
