Active matrix display device

An active matrix display device is provided in which parasistic capacitance or the like is suppressed by forming a thick insulating film around an organic semiconductor film, and disconnection or the like does not occur in an opposing electrode formed on the upper layer of the thick insulating film. In the active matrix display device, first, a bank layer composed of a resist film is formed along data lines and scanning lines. By depositing an opposing electrode of a thin film luminescent element on the upper layer side of the bank layer, capacitance that parasitizes the data lines can be suppressed. Additionally, a discontinuities portion is formed in the bank layer. Since the discontinuities portion is a planar section which does not have any a step due to the existence of the bank layer, disconnection of opposing electrode does not occur at this section. When an organic semiconductor film is formed by an ink jet process, a liquid material discharged from an ink jet head is blocked by the bank layer.
