In the arrangement shown in
In the pixel 110, the selection transistor 113 is rendered conductive in response to a write signal applied from the vertical driving circuit 103 to the gate electrode via the scanning line 121. By this operation, an image signal or a reference voltage according to luminance information is sampled from the signal line 124. When the reference voltage is sampled from the signal line 124, a threshold voltage variation in the driving transistor 112 of each pixel can be corrected, and a luminance variation in each pixel caused by the threshold voltage variation can be reduced. The image signal or the reference voltage is applied to the gate electrode of the driving transistor 112 and also held by the capacitive element 116.
