摘要： A liquid discharge apparatus includes a nozzle, a pressure chamber and a liquid supply portion that supplies the liquid to the pressure chamber. A discharge pulse generating unit generates a discharge pulse to discharge the liquid. The viscosity of the liquid is no less than 8 millipascal-seconds. The nozzle has a first portion with a discharge side that has an opening area smaller than that of a pressure chamber side and a second portion that communicates with an end portion of the discharge side. An opening area of the second portion is no greater than 1/9 of the opening area of the pressure chamber side. The discharge pulse has a decompression portion that decompresses the liquid to lead a meniscus in the second portion to the first portion and a compression portion that compresses the liquid to discharge the liquid before the meniscus returns to the second portion.

摘要： A piezoelectric element changes a pressure in a pressure chamber and ejects ink from nozzles. A driving signal generating section generates a driving signal that includes an ejection pulse PA and PB which eject ink to a piezoelectric element, and a first transition element between the ejection pulse PA and PB. A starting end and a terminal end of the ejection pulse PA are set to a reference electric potential VA, and a starting end and a terminal end of an ejection pulse PB are set to a reference electric potential VB. An electric potential difference between the reference electric potential VA and the lowest electric potential of the ejection pulse PA is smaller than an electric potential difference between the reference electric potential VB and a highest electric potential of the ejection pulse PB, and the reference electric potential VA is lower than the reference electric potential VB.
