Summary:1. Field of the Invention There is provided a semiconductor integrated circuit device for driving a display element of an organic EL display device, in which an output current is controlled with high accuracy. The semiconductor integrated circuit device includes a field effect MOS transistor capable of obtaining a high accuracy output current and used for an output circuit for driving the display element of the organic EL display device, and further, a fuse trimming element is provided to its gate electrode, so that the device is constructed by the field effect MOS transistor capable of obtaining a more accurate output current. Besides, the field effect MOS transistor has such a structure that even if Vth fluctuates, fluctuation in an output current value is kept low.
