摘要： A multi-nozzle ink jet head having a diaphragm that effectively utilizes the force generated by thin-film piezoelectric elements is disclosed. The head (2) has a head substrate (28) in which are formed a plurality of nozzles (39) and a plurality of pressure chambers (29), a multi-layer diaphragm (23-1, 23-2), piezoelectric elements (27), and individual electrodes (26). By making the thickness of the common electrode layer (23-1) of the multi-layer diaphragm be thin but such that problems do not occur during multi-pin driving, optimization of the rigid layer becomes possible, and hence it is possible to use the force generated by the thin-film piezoelectric elements efficiently in ink ejection.

摘要： A multi-nozzle ink jet head formed through semiconductor processes. The multi-nozzle head has a head substrate in which are formed a plurality of nozzles and a plurality of pressure chambers, a diaphragm that acts as a common electrode and covers the plurality of pressure chambers, piezoelectric body layers that are provided in correspondence with the pressure chambers on the diaphragm, and individual electrode layers that are provided on the piezoelectric body layers and have individual electrode parts corresponding to the pressure chambers and wiring parts for the individual electrode parts. By interposing a low-dielectric-constant layer or an insulating layer in the region of the wiring parts, or not disposing the common electrode in the region of the wiring parts, the electrical capacitance of the driving parts is reduced, and hence a driving lag is prevented from occurring, and moreover unwanted vibration of the piezoelectric bodies is prevented.

摘要： A liquid crystal display device includes a liquid crystal panel and an illumination unit. The illumination unit has a planar light emitting region formed by an EL element. The light emitting region is formed by a plurality of linear light emitting regions that extend in a direction perpendicular to the vertical scanning direction of liquid crystal. The linear light emitting regions are switched between a light emitting state and a non-light emitting state based on a command signal from a controller in a manner that the linear light emitting regions sequentially emit light in synchronization with vertical scanning of the liquid crystal. Each linear light emitting region is controlled to be in the non-light emitting state at least during a drive data rewriting period of a portion of the liquid crystal immediately above the linear light emitting region.

摘要： An area lighting unit has an electroluminescent device, a light scattering portion on a side of a light exit surface of the electroluminescent device, and a light covering portion on a side of a light exit surface of the light scattering portion. The light converging portion includes first and second layered optical sheets, each having a planar light incidence portion through which light enters and a light exit portion through which the light exits. The light exit portion of each optical sheet forms parallel prismatic protrusions, each having a vertex angle of 90 degrees to 105 degrees. The optical sheets each are so arranged that the light incidence portion is oriented to the electroluminescent device and a direction in which the protrusions of the first optical sheet are arranged is perpendicular to a direction in which the protrusions of the second optical sheet are arranged.
