Problems solved by technology
The magnitude of the potential difference gradient caused by the distance between electrodes has a great influence on the design of the display element, and there is no understanding of issues such as burn-in and drop marks that are difficult to predict from conventional technologies.

Embodiment 1
[0258] (Example 1 (Liquid Crystal Composition 1) and Comparative Example 1)
[0259] A liquid crystal composition (liquid crystal composition 1) having the composition shown below was prepared, and its physical property values were measured. The results are shown in the table below.
[0260] Furthermore, the prepared liquid crystal composition 1 was poured into the said liquid crystal display element, and the evaluation of various physical property values and display characteristics was performed.
[0261] Simultaneously, the liquid crystal composition of Comparative Example 1 having a different structure from the liquid crystal composition specified in the present invention was prepared, and a liquid crystal display element was fabricated and evaluated in the same manner.
[0262] In addition, the symbol on the left side of the content is the description of the abbreviation of the said compound.

Embodiment 2
[0273] (Example 2 (Liquid Crystal Composition 2) and Comparative Example 2)
[0274] A liquid crystal composition (liquid crystal composition 2) having the composition shown below and the liquid crystal composition of Comparative Example 1 were prepared, and an FFS mode liquid crystal display element was prepared in the same manner, and its physical properties were measured. The results are shown in the table below.
[0275] Simultaneously, the liquid crystal composition of Comparative Example 2 having a different structure from the liquid crystal composition specified in the present invention was prepared, and a liquid crystal display element was fabricated and evaluated in the same manner.

Abstract
A dispenser (100) comprises a bottle (110) having an external wall (111), a gasket (120) defining an upper cavity(112) and a lower cavity(114) within the bottle and configured to substantially seal said upper cavity (112) form said lower cavity (114), and a fluid dispensing mechanism configured to allow fluid to be dispensed from said lower cavity (114) to the outside of the bottle (110) when the dispensing mechanism is actuated, wherein said gasket (120) is capable of moving towards the lower cavity (114) upon actuation of the dispensing mechanism and of moving towards the upper cavity (112) upon entrance of the fluid into said lower cavity (114), and a fluid refill mechanism configured to allow fluid to enter said lower cavity (114) when said refill mechanism is fluidly coupled to a fluid source.
