Abstract
A liquid crystal display deviceincludes: a transparent substratea plurality of signal linesand scan linesarranged on the transparent substratein a matrix; a plurality of auxiliary capacitor linesprovided between the scan linesso as to be in parallel with the scan linesthin film transistors (TFTs) each provided in a vicinity of an intersection of the signal linesand scan linesand pixel electrodesarranged in respective positions defined by the signal linesand the scan linesand each electrically connected to a drain electrode D of the thin film transistor (TFT); in which the thin film transistor (TFT)'s gate electrode G and the scan lineare covered by a gate insulating film formed by an insulating film (a first layer)and an insulating layer (a second layer)and the drain electrode D of the thin film transistor (TFT) extends to overlie an auxiliary capacitor electrodea, with the insulating layer (the second layer)interposed between the drain electrode D and the auxiliary capacitor electrodea. As a result, it will be possible to provide a liquid crystal display device and a method for manufacturing the same are provided, in which the capacitance of an auxiliary capacitor electrode is increased without reducing the aperture ratio of each pixel and which is suitable to realize a relatively small pixel area and high definition.
