Abstract:
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.
