Abstract
A semiconductor device includes a first electrode disposed over an element substrate, an insulating layer covering an end of the first electrode, an organic layer disposed over the first electrode and the insulating layer, and a second electrode disposed over the organic layer. The insulating layer includes a step portion and a steeply inclined portion, and a distance from the step portion to a contact portion where the first electrode and the organic layer are in contact is greater than a distance from the step portion to the steeply inclined portion. In a cross section, a height of the steeply inclined portion is greater than a thickness from the first electrode to the first light-emitting layer in the contact portion, and a depth of the step portion is greater than the height of the steeply inclined portion and smaller than a thickness of the organic layer in the contact portion.
