Abstract
A display device including TFTs in a pixel area and in a peripheral driving area in which the number of through-holes in a TFT circuit is decreased, and the mounting density of the TFTs is improved, so that a high-resolution display can be achieved. The display device includes a display area in which pixels are disposed in a matrix form, and a TFT substrate, on which a peripheral driving circuit is disposed, on the outer side of the display area. The pixels or the peripheral driving circuit includes TFTs (thin film transistors) each of which is formed in such a way that a first gate electrode of each TFT is formed relative to a semiconductor layer with a first gate insulating film therebetween, and a drain electrode and a source electrode of each TFT that are connected to the semiconductor layer are formed at layers different from each other.
