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.
