Abstract:
1. A personal communication device having a display unit, said display unit comprising: a substrate; a first insulating film formed over the substrate; a pixel matrix formed on the first insulating film, said pixel matrix comprising plural pixels and each of said pixels comprising at least one switching thin film transistor formed on and in contact with a first side of the first insulating film, and a pixel electrode connected to said switching thin film transistor; and a logic circuit formed on the first insulating film, said logic circuit comprising at least one driver thin film transistor formed on and in contact with the first side of the first insulating film and including source and drain electrodes, wherein at least a part of said logic circuit is covered with said pixel electrode, wherein a power source interconnect is connected to one of said source and drain electrodes, wherein a second insulating film is formed over said switching thin film transistor and said driver thin film transistor, wherein a third insulating film is formed over said second insulating film, wherein said pixel electrode is formed over said third insulating film, and wherein said power source interconnect is formed on said second insulating film and is between said pixel electrode and one of said source and drain electrodes.
