    • A liquid crystal composition is provided that satisfies at least one characteristic among the characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a large optical anisotropy, a large dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or is properly balanced regarding at least two characteristics. An AM device is provided that has a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth. The liquid crystal composition having a nematic phase contains a specific five-ring compound having a large maximum temperature as the first component, a specific compound having a small viscosity as the second component, and a specific four-ring compound having a high maximum temperature as the third component. The liquid crystal display device contains the liquid crystal composition.

    • A printing apparatus includes a first circulation pump which is provided in a channel between a print head and a first storage tank and which supplies ink from a second storage tank to the print head. The printing apparatus further includes a second circulation pump which is provided in a channel between the first storage tank and the second storage tank which supplies ink from the first storage tank to the second storage tank. The printing apparatus further includes a control unit which controls the driving of the first circulation pump and second circulation pump, and a detecting unit which detects the amount of ink stored in the second storage tank. The control unit controls the driving of the second circulation pump on the basis of a detection result by the detecting unit.
