An EL display device capable of performing clear multi-gradation color
display and electronic equipment provided with the EL display device are
provided, wherein gradation display is performed according to a
time-division driving method in which the luminescence and
non-luminescence of an EL element (109) disposed in a pixel (104) are
controlled by time, and the influence by the characteristic variability
of a current controlling TFT (108) is prevented. When this method is
used, a data signal side driving circuit (102) and a gate signal side
driving circuit (103) are formed with TFTs that use a silicon film having
a peculiar crystal structure and exhibit an extremely high operation
speed.
