Abstract
An electroluminescent (EL) display apparatus and manufacturing method are provided. A display screen includes gate signal lines which are arranged to intersect source signal lines. A pixel corresponds to each intersection of the gate signal lines and the source signal lines. Each pixel includes: an EL device; a driving transistor to supply a current to the EL device; a first switch transistor through which the current is supplied by the driving transistor to the EL device; a second switch transistor provided to supply, to the driving transistor, an image signal supplied to a corresponding one of the source signal lines; a third switch transistor provided between a gate terminal and a drain terminal of the driving transistor; and a capacitor connected to the gate terminal of the driving transistor for holding the image signal. The third switch transistor has a multi-gate structure.
