Abstract:
An active matrix type display apparatus of the present invention includes a plurality of pixels (50) disposed in a matrix arrangement. Each of the pixels (50) includes a light-emitting element (9) which emits light in response to a supplied current, a signal line (13) connected to a signal line drive circuit (23) which supplies a luminance signal corresponding to a luminance of light emission of the light-emitting element (9), the luminance signal being a current signal, a driver element (6) which controls a current value of the luminance signal supplied to the light-emitting element (9), a luminance signal retention capacitor (8) which retains, as a luminance signal voltage, a potential difference generated between a drain electrode and a source electrode of the driver element (6) when the luminance signal is supplied to the driver element (6) via the signal line (13), and a threshold voltage detection and addition unit (20) which detects a threshold voltage of the driver element (6) and causes a voltage obtained by adding the luminance signal voltage being retained in the luminance signal retention capacitor (8) to the detected threshold voltage to be applied at a gate electrode of the driver element (6).
