ABSTRACT:
A liquid crystal display device10includes: a transparent substrate11;a plurality of signal lines17and scan lines16arranged on the transparent substrate11in a matrix; a plurality of auxiliary capacitor lines18provided between the scan lines16so as to be in parallel with the scan lines16;thin film transistors (TFTs) each provided in a vicinity of an intersection of the signal lines17and scan lines16;and pixel electrodes20arranged in respective positions defined by the signal lines17and the scan lines16and 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 line16are covered by a gate insulating film formed by an insulating film (a first layer)25and an insulating layer (a second layer)26,and the drain electrode D of the thin film transistor (TFT) extends to overlie an auxiliary capacitor electrode18a, with the insulating layer (the second layer)26interposed between the drain electrode D and the auxiliary capacitor electrode18a. 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.
