An inkjet head is provided. The inkjet head includes an ink reservoir to store ink, an ink inlet, through which the ink is introduced to the ink reservoir, an ink outlet, through which the ink in the ink reservoir is allowed to flow to the inkjet nozzle. The ink reservoir has a wall arising from a bottom of the ink reservoir to divide the ink reservoir into a plurality of ink chambers. The plurality of ink chambers include a first ink chamber and a second ink chamber. The plurality of ink chambers are in fluid communication with each other over a top edge of the wall. The wall is formed to include a through hole, which is formed in a vicinity of the bottom of the ink reservoir and allows the plurality of ink chambers to be in fluid communication with each other.

摘要:
The invention provides a liquid crystal compound that has a large negative dielectric anisotropy (Δ∈) and also has at least one of characteristics such as the stability to heat, light or the like, a high clearing point, a suitable refractive index anisotropy (Δn), a large negative dielectric anisotropy (Δ∈) and an excellent compatibility with other liquid crystal compounds. An excellent effect in which especially the value of the dielectric anisotropy (Δ∈) is increased negatively is achieved by use of the compound having two moieties of 1) a tetrahydropyran ring and and thus the effect is utilized.
