An active matrix substrate is provided which does not cause reductions in
the brightness of electroluminescence elements, and which comprises
appropriate peripheral circuitry occupying a small area. The active
matrix substrate comprises peripheral circuits to supply current to EL
elements provided for each pixel, and corresponding to EL elements, and
further comprises a holding element (C) which holds a control voltage, a
first active element (T1) connected to the holding element (C) and which
supplies current to a light-emitting portion (OLED) based on a control
voltage, and a second active element (T2) connected to the holding
element (C) and which controls the charging and discharging of the
holding element. In particular, the second active element (T2) is
configured as a multiple-control-terminal type active element. As a
result, there are no fluctuations in the programmed current.
