With a new function introduced neither to a file server nor to a client terminal, control of displaying only a file or a folder whose access right is held by a user is enabled by using existing file server and client terminal. The present invention can impart superior texture in view of softness, smoothness and the like to wipe paper such as tissue paper, toilet paper or the like, wherein the color of the wipe paper does not change, and water absorbability is not inhibited. Through these mechanisms, the pharmaceutical and method can prevent and treat demyelination-associated neural function impairing diseases. A package-component member having a hole corresponding to the optical functional element is abutted to the bank such that the hole is opposed to the function part of the functional element. The display device includes: a vacuum region defined by a pair of spaced apart, resilient and gas impermeable support barriers formed to integrally extend from at least one of the upper and lower panels of the display device and having the other end in vacuum region closing contact with the other display panel where the vacuum region is positioned in a peripheral area of the display device.
