The application aims at reducing the power consumption of pixels not emitting light in an active matrix organic EL panel having a static memory cell in each pixel. Each pixel circuit comprises a selection transistor (5), first (2) and second (4) drive transistors as well as a first organic EL element (1) and a second (3) organic EL element respectively connected to the first and second drive transistors. The second organic. EL element is masked and does not contribute to the pixel brightness. The current flowing through the second organic EL element is reduced by current limiting means. This current limiting means may be a second supply voltage (VDD2) used in the current path with the second organic EL element, the second supply voltage being lower than the corresponding first supply voltage (VDD1) of the current path with the first organic EL element. Alternatively, the current limiting means may comprise a current limiting transistor (11) or a diode-connected transistor (13).
