Display device and electronic apparatus having a wiring connected to a counter electrode via an opening portion in an insulating layer that surrounds a pixel electrode

A display device comprising:

• a transistor whose channel portion is formed of an amorphous semiconductor;
• a connecting wiring connected to a source electrode or a drain electrode of the transistor;
• a light emitting element having a laminated structure which includes a pixel electrode, an electro luminescent layer, and a counter electrode;
• an insulating layer surrounding an end portion of the pixel electrode;
• an auxiliary wiring formed in the same layer as either a gate electrode of the transistor, the connecting wiring, or the pixel electrode;
• and
• a driver circuit controlling the transistor and the light emitting element,
• wherein the connecting wiring is connected to the pixel electrode;
