  • Publication number: 20240042771
    Abstract: A liquid ejecting apparatus includes a common liquid chamber communicating with nozzles, a filter partitioning the common liquid chamber into an upstream chamber and a downstream chamber, an inlet and an outlet for the upstream chamber, a liquid storage section, a supply flow path, and a recovery flow path. A beam portion is provided inside the downstream chamber. A pressurization discharge operation for discharging the liquid from the nozzles by pressurizing the supply flow path and a circulation operation for circulating the liquid in a circulation path including the liquid storage section, the supply flow path, the common liquid chamber, and the recovery flow path, are performed. In a process of filling the circulation path with the liquid, the circulation operation is performed after the pressurization discharge operation is performed.

A beam portion is provided inside the downstream chamber. A pressurization discharge operation for discharging the liquid from the nozzles and a circulation operation for circulating the liquid in a circulation path are performed. In the filling process of filling the circulation path with the liquid, after the first circulation operation is performed, a predetermined operation for moving the liquid inside the downstream chamber in a direction different from a direction in which the liquid inside the downstream chamber is moved by the circulation operation is performed, and thereafter, the pressurization discharge operation is performed.

  • Publication number: 20190101798
    Abstract: An electro-optical device includes a pixel electrode provided over one side of a substrate, a conductive layer provided between the substrate and the pixel electrode, and a relay electrode provided between the substrate and the conductive layer. The conductive layer includes a first conduction section protruding toward the pixel electrode and a second conduction section protruding toward the relay electrode. The first conduction section has an upper surface which is in contact with the pixel electrode and the second conduction section has a bottom surface which is in contact with the relay electrode. The upper surface of the first conduction section is a part of the conductive layer that is farthest from the substrate. The pixel electrode is electrically connected to the relay electrode through the conductive layer. At least an inside of the first conduction section is filled with an insulating material.

  • Patent number: 9529220
    Abstract: In the electro-optical device, a pillar-shaped protrusion is formed on an insulating film (a first insulating film) provided below a pixel electrode in the downward direction, and thus a conduction section of a second electrode layer (a conductive layer) overlaps the highest surface of the pillar-shaped protrusion. An inter-layer insulating film (a second insulating film) is provided between the second electrode layer and the pixel electrode, but the conduction section is exposed on a surface of the inter-layer insulating film. For this reason, the pixel electrode is electrically connected to the conduction section, when the pixel electrode is laminated on the inter-layer insulating film.
