Display device and driving method of the same, and electronic apparatus

A display device comprising:

• a column signal line;
• a row signal line intersecting with the column signal line at an intersection portion;
• a light emitting element comprising a first layer containing a first light emitting layer interposed between the column signal line and the row signal line at the intersection portion;
• at least two monitoring elements each of which comprises a second layer containing a second light emitting layer interposed between a first electrode and a second electrode;
• a current source;
• and
• an amplifier,
• wherein one of the first electrodes of the at least two monitoring elements is electrically connected to the current source,
• wherein one of the first electrodes of the at least two monitoring elements is electrically connected to an input terminal of the amplifier,
• wherein an output of the amplifier is inputted to the column signal line, and
• wherein the first layer is directly in contact with the column signal line and the row signal line.
