Abstract
A display device in which variations of characteristics of a TFT are eliminated and the aperture ratio is improved is provided. A display device has a thin film transistor on an insulating substrate. The thin film transistor includes first gate electrodes, a gate insulating film, a semiconductor filmwhich is formed on the first gate electrode, and a interlayer insulating film. The thin film transistor further includes second gate electrodeswhich are on the interlayer insulating filmand at least above channels, and which are connected to the first gate electrodes. A reflective display electrodeconnected to the source of the thin film transistor is elongated to extend above the thin film transistor.
