    Abstract: A bank has an opening including a first opening and a second opening. The second opening extends from the first opening in such a direction that the second opening overlaps the first electrode. The second opening at least partially overlaps the first electrode. The first electrode has an end close to the first opening and overlapping the second opening. The second opening has a maximum width smaller than a maximum width of the first opening. The widths are measured perpendicular to the direction in which the second opening extends from the first opening.

    Abstract: A display device includes a base material, a thin film transistor provided on the base material, a light-emitting-element layer provided on the thin film transistor layer and including a plurality of light-emitting elements each including a first electrode, a functional layer, and a second electrode. The plurality of light-emitting elements are formed to emit lights in different colors. The display device also includes: a contact portion provided to a frame region and electrically connecting together a terminal unit provided to the frame region and the second electrode through a routed wire; and a block structure shaped into a frame and provided to the contact portion beside a display region, in order to block formation of the functional layer on the contact portion.

    Abstract: A display device includes a light-emitting element layer including a plurality of light-emitting elements. The light-emitting element layer includes, for each of the plurality of light-emitting elements, a first electrode and a plurality of openings exposing the first electrode, and includes an edge cover covering an end portion of the first electrode, a plurality of light-emitting layers covering each of the plurality of openings, and a second electrode that is common to the plurality of light-emitting elements and covers the plurality of light-emitting layers. The second electrode includes a metal nanowire. Furthermore, the light-emitting element layer includes an auxiliary wiring line provided in a lattice pattern in a position overlapping the edge cover, and the auxiliary wiring line and the metal nanowire are electrically connected to each other.

    Abstract: A display device (500) includes a sub-pixel (100) including a light-emitting element layer (10). The sub-pixel (100) includes: a first electrode (12); an edge cover (11); a projection (15) projecting from the front face of the first electrode (12); and a functional layer (13). With respect to the front face of the first electrode (12) where a first height (h1) is a height up to a front face of a protrusion of the functional layer (13) provided along an edge of the projection (15), a second height (h2) is a height up to a tip of the projection (15), and a third height (h3) is a height up to a front face of the edge cover (11), the second height (h2) is greater than the first height (h1) and smaller than the third height (h3).
