Display device

A display device comprising a plurality of pixels arranged in a matrix on a substrate along a first direction and a second direction intersecting the first direction,

• each of the plurality of pixels comprises:
• a transistor;
• a first transparent conductive layer arranged over the transistor and electrically connected to the transistor;
• a first insulating layer arranged over the first transparent conductive layer;
• a second transparent conductive layer arranged in the first insulating layer and electrically connected to the first transparent conductive layer via an opening extending over the plurality of pixels arranged in line in the first direction;
• a second insulating layer arranged over the second transparent conductive layer;
• a third transparent conductive layer arranged over the second insulating layer;
• a filling member arranged over the third transparent conductive layer to fill the interior of the opening;
• and
• a metal layer in contact with the third transparent conductive layer and the filling member,
• wherein
• the filling member has a protrusion portion protruding above a top surface of the second transparent conductive layer arranged above the first insulating layer, and
• the metal layer is arranged above the protruding portion.
