A liquid crystal display device according to one aspect of the present invention includes a liquid crystal panel of a vertical alignment mode, and an optical control member disposed on a light-exiting side of the liquid crystal panel. The liquid crystal panel includes a plurality of pixels having at least two domains (), in which directors of liquid crystal molecules are in a first direction. An absorption axis of a first polarizing sheet and an absorption axis of a second polarizing sheet are a mutually orthogonal and form angle that is approximately 45&#xb0;. The optical control member includes a base, a light diffusion part, a light blocking layer and a low refractive index part. A planar shape of the light blocking layer () when seen from a normal line direction of the base has a straight line part parallel to the absorption axis (P, P) of one of the first polarizing sheet and the second polarizing sheet and a straight line part forming an angle of less than 45&#xb0; with the absorption axis (P, P) of one polarizing sheet.

An object is to provide a storage container including latent heat storage materials that provide a high cold insulation effect. A storage containerhas an electric cooling function and stores an object. The storage containerincludes at least one storage chamberthat stores the object; a first latent heat storage material A that is disposed in the storage chamberand has a predetermined phase change temperature; and a second latent heat storage material B that is disposed in the storage chamberand has a phase change temperature higher than the phase change temperature of the first latent heat storage material A.

Storage container

A storage container can maintain a temperature inside a storage room not to cause a temperature distribution for a certain time even if the operation is stopped. In a storage containerstoring preserved goods and having an electrical cooling function, the storage containerincludes a container bodyand a door. A space enclosed by the container bodyand the doorforms a storage room. The container bodyand the doorhave respectively heat insulating portionsand heat accumulating portions. The heat accumulating portionsare each made of at least one type of material that causes liquid-solid phase transition at a temperature between a controllable temperature inside the storage roomand a living environmental temperature. A value obtained by dividing temperature conductivity of the material by an amount of the material used per unit area of a wall surface of the storage roomis smaller in the heat accumulating portionsarranged near a first area where a temperature is more apt to come closer to the living environmental temperature under a temperature distribution that is formed inside the storage roomwith changes over time after stop of cooling, than in the heat accumulating portionsarranged near a second area where a temperature is less apt to come closer to the living environmental temperature thereunder.

Provided are an image display device in which a desired number of panels are combined so that a large light-emitting surface is realized, a panel provided in the image display device, and a method for manufacturing the panel. For this purpose, a panel () of the present invention includes a rectangular light-emitting section (); a substrate () having a flat surface (') on which the rectangular light-emitting section () is provided and a curved adjacent surface (&#x2032;) that is adjacent to one of edge portions of the flat surface which extend along long sides of the rectangular light-emitting section (); and a terminal group that is drawn out from a long side of the rectangular light-emitting section () and that is disposed in the adjacent surface. The panels () are connected to each other by linking edge portions of the flat surfaces (&#x2032;) of the respective substrates () so that longitudinal directions of the respective rectangular display sections () are parallel to each other and so that the adjacent surface (&#x2032;) is located on the back side of the substrate (). In an image display section, pixels () are arranged in a matrix, and sub-pixels in each of the pixels () are aligned in a column direction of the matrix.
