A display device including a current drive circuit capable of stably and
correctly supplying an intended current to a light emitting element of
each pixel without being affected by variations in characteristics of an
active element inside the pixel and as a result capable of displaying a
high quality image, wherein each pixel comprises a receiving use
transistor TFT3 for fetching a signal current Iw from a data line DATA
when a scanning line SCAN-A is selected, a conversion use transistor TFT1
for once converting a current level of a fetched signal current Iw to a
voltage level and holding the same, and a drive use transistor TFT2 for
passing a drive current having a current level in accordance with the
held voltage level through a light emitting element OLED. The conversion
use thin film transistor TFT1 generates a converted voltage level at its
own gate by passing the signal current Iw fetched by the TFT3 through its
own channel. A capacitor C holds the voltage level created at the gate of
the TFT1. The TFT2 passes the drive current having a current level in
accordance with the held voltage level through the light emitting element
OLED.
