Abstract: In an organic EL display device, a frame region provided outside a display region is provided with a damming wall extending on an outer periphery of the display region and a second lead-out wiring line extending across the damming wall from the display region side to an outside of the frame region. The damming wall includes a bank portion having a projecting shape and provided, in a part in which the second lead-out wiring line extends, on both sides in a direction in which the second lead-out wiring line extends with respect to a top portion of the damming wall. The bank portion is lower than a top portion of a second damming wall and forms, between the bank portion and the top portion, a trap portion having a recessed shape.

Abstract: A display device includes a display panel including a base substrate layer, a thin film transistor layer, a light-emitting element layer, and a sealing film, and includes an image capturing unit provided on the base substrate layer side of a display region of the display panel. A plurality of subpixels constituting the display region are divided into a group of normal subpixels provided so as not to overlap with the image capturing unit and a group of thinned-out subpixels provided so as to overlap with the image capturing unit. The inorganic insulating film is provided with openings passing through the inorganic insulating film, in an image capturing region overlapping with the group of thinned-out subpixels.
