1. An electroluminescent (EL) display device comprising:
a display screen including a plurality of pixels arranged in rows and columns; a first gate signal line and a second gate signal line which are disposed for each of the rows of the plurality of pixels; a gate driver circuit which outputs a first control voltage to the first gate signal line and a second control voltage to the second gate signal line; a current generating circuit which supplies a current to the plurality of pixels of the display screen; a current amount obtaining circuit which obtains a magnitude of a current flowing through the plurality of pixels; and a control voltage generating circuit which generates the first control voltage output by the gate driver circuit to the first gate signal line, wherein each of the plurality of pixels includes: an EL element; a driving transistor which supplies a driving current to the EL element; a first switching transistor disposed in a path of the driving current, the first switching transistor having a voltage applied across a channel and adjusted based on the first control voltage supplied from the first gate signal line; and a second switching transistor which switches between a conducting state and a non-conducting state based on the second control voltage supplied from the second gate signal line, the second switching transistor applying a video signal to the driving transistor, and wherein the control voltage generating circuit adjusts a magnitude of the first control voltage based on an output result from the current amount obtaining circuit. |
