摘要： The present invention provides a picture element driving circuit of an active matrix display device, with a configuration of no through-holes, including two or more FETs. A display device of the present invention has a structure in which a first field-effect transistor (213) and a second field-effect transistor (211) are provided, insulation films of the first and second field-effect transistor are formed on the same layer, and semiconductors used as channels of the two field-effect transistors are formed on both surfaces of the insulation film, respectively. The display device has an electric circuit of a structure in which one of source/drain electrodes of the first field-effect transistor (311) is used as a gate electrode of the second field-effect transistor.
