ABSTRACT:
Variation occurs in transistor characteristics. The present invention relates to a signal line driver circuit comprising: a plurality of current source circuits corresponding to a plurality of wirings; and a shift register, characterized in that: the plurality of current source circuits each comprise capacitor means for converting a supplied current to a voltage in accordance with a sampling pulse supplied from the shift register and supply means for supplying a current corresponding to the converted voltage.
