Abstract: First overlying wires are provided between a display area and a bending portion, extending parallel to each other in a direction crossing the direction in which the bending portion extends. Underlying wires are provided between a first resin layer and a second resin layer on a resin substrate, extending across a slit and parallel to each other in a direction crossing the direction in which the bending portion extends. The first overlying wires are electrically connected respectively to the underlying wires via first contact holes formed through the second resin layer and inorganic insulation films.

Abstract: A second test portion includes a second test first terminal, a second test second terminal, a second test third terminal, and a second test fourth terminal electrically connected to a second test semiconductor layer via respective contact holes formed in a layered film of a gate insulating film and an interlayer insulating film, and the layered film of the gate insulating film and the interlayer insulating film in the second test portion is provided with an opening open upward between at least one of the second test first terminal, the second test second terminal, the second test third terminal, and the second test fourth terminal.

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.

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 second connection wire is electrically connected to a first connection wire via a display-side contact portion and terminal-side contact portion in a bending section. The first connection wire and the second connection wire do not overlap each other at least partly between the display-side contact portion and terminal-side contact portion.

Abstract: An image forming apparatus includes an image bearer to bear a latent electrostatic image thereon, a developing device to supply a development agent to the latent electrostatic image to obtain a visible image, a transfer roller to contact the image bearer to transfer the visible image to a recording medium, a replenishing device to replenish the developing device with the development agent when a density value read from a density detection pattern formed on the image bearer by the developing device is equal to or less than a threshold, a processing device to conduct a predetermined processing to reduce attachment of the development agent to the transfer roller, and a control device to control the number of times the predetermined processing is performed or processing time in performing the predetermined processing for the processing device, based on whether there is replenishment of the development agent to the developing device.
