A wiring substrate is provided with a surface wiring on at least one surface, a through hole which passes through the wiring substrate, and a through wiring which is formed in the through hole and is connected to a surface wiring, in which an inner surface of the through hole is a rough surface, and electric resistance of the through wiring is equal to or less than the electric resistance of the surface wiring.

Wiring substrate, MEMS device, liquid ejecting head, and liquid ejecting apparatus

A liquid ejecting head includes a pressure chamber formation substrate having a pressure chamber formed therein, a flow path formation substrate that is connected to the pressure chamber formation substrate, and that has a flow path in communication with the pressure chamber formed in a state penetrating through the flow path formation substrate in a thickness direction thereof, and a nozzle plate that is connected to the flow path formation substrate on an opposite side to the pressure chamber formation substrate, and that has a nozzle in communication with the flow path opened therein. The flow path formation substrate is configured from a single substrate, and an opening area on a pressure chamber side of the flow path is formed wider than an opening area on a nozzle side of the flow path.

Liquid ejecting head, liquid ejecting apparatus, and liquid ejecting head manufacturing method

An inclined plane which inclines toward a lower plane of a ceiling portion, that is, the lower plane of a communication substrate from a ceiling plane of a second liquid chamber is formed in the second liquid chamber of the communication substrate. Therefore, an individual communication opening is formed, in a state of penetrating the communication substrate from the inclined plane. One end (lower end) of the individual communication opening communicates with the second liquid chamber by being open onto the inclined plane, and the other end (upper end) of the individual communication opening individually communicates with a pressure chamber of a pressure chamber forming substrate by being open onto an upper plane of the communication substrate. When a thickness of the communication substrate is referred to as T, a length of the individual communication opening is referred to as L, and a substantial depth of the second liquid chamber is referred to as D, the dimensions are configured so as to be L+D&#x3e;T.

Flow path component, liquid discharge head, and liquid discharge apparatus

A piezoelectric actuator which is provided on the flow path formation substrate, and a protection substrate which is bonded to the flow path formation substrate on the piezoelectric actuator side, the method including: bonding the flow path formation substrate on which the piezoelectric actuator is formed, and the protection substrate to form a bonded body; bonding a sealing member to the protection substrate of the bonded body on the surface side opposite the flow path formation substrate, and disposing a protection material containing a nitro compound in a space between the sealing member and the protection substrate.

Manufacturing method of liquid ejecting head

A color display device includes a display area where a non-rectangular display range is determined. Pixels of which a display color is set to a mixed color formed by adjusting brightness of sub-pixels having a plurality of different single-colors are arranged within the display area. In addition, parts of the pixels subjected to non-coloring drive and display are arranged so as to extend to the contour of the display area.

Color display device with a non-rectangle display

A liquid crystal device is provided that comprises a plurality of R colored layers, a plurality of G colored layers, and a plurality of B colored layers that are formed on either one of a pair of substrates and are aligned in a predetermined arrangement in plan view, a light-shielding layer formed between the colored layers, and a plurality of spacers formed on either one of the pair of substrates and protruding toward the other substrate. The plurality of spacers is formed around the B colored layers and/or the R colored layers, but is not formed around the G colored layers. Thus, even if a positional deviation occurs between the substrates, the spacers do not get into the G colored layers.

Electro-optical device and electronic apparatus device

A liquid crystal device is provided that comprises a plurality of spacers formed on a first substrate, a plurality of R colored layers, G colored layers, and B colored layers formed on a second substrate opposite to the first substrate, and a light-shielding layer formed between the colored layers. The plurality of spacers is provided around the respective colored layers, and the dimensions of the spacers is set to be Zg&#x3c;Zb and Zg&#x3c;Zr, and preferably, Zg&#x3c;Zr&#x3c;Zb corresponding to the respective colored layers. Thus, even if an assembly error occurs in attaching the substrates, the possibility that the spacers may get into the G colored regions is suppressed.
