1. An organic EL element, comprising:

  • a substrate;

    a thin film transistor disposed in the substrate;

    a pixel electrode layer disposed on the substrate, the pixel electrode layer including a light-reflective material;

    banks disposed on the substrate and on the pixel electrode layer, covering edge portions of the pixel electrode layer and a portion of a contact region of the pixel electrode layer, the contact region being for electrically connecting the pixel electrode layer;

    a light-emitting layer disposed above the pixel electrode layer;

    an opposing electrode layer disposed above the light-emitting layer, the opposing electrode layer including a light-transmissive material; and

    a light-shielding layer disposed higher than the pixel electrode layer, the light-shielding layer overlapping the edge portions of the pixel electrode layers, whereina source or a drain of the thin-film transistor is connected to the pixel electrode layer via a connecting recess in which a portion of the pixel electrode layer is recessed in a direction of the substrate, andin the plan view of the substrate, the light-shielding layer does not overlap with the connecting recess.
