Abstract: In order to examine a degree of monocular diplopia is easily examined in a quantitative manner, a plurality of circular eye marks are seen from a predetermined examination distance with a single eye of a patient to find a particular eye mark whose double vision images are observed to be circumscribed each other, and a degree of monocular diplopia is determined by a view angle of the relevant circular eye mark. Since the eye mark is formed as a circular pattern, a degree of monocular diplopia can be examined irrespective of an axial direction along which double vision images appear.

Abstract: To provide a display which can improve viewing angle dependency of a contrast ratio at least in a specific azimuth without design change of a basic structure of a display element, limitation to white display state or black display state, and deterioration in display quality in other directions. The above-mentioned display is a display comprising: a display element with a contrast ratio dependent on a viewing angle; and an anisotropic scattering film having an anisotropic scattering layer, wherein the anisotropic scattering film is located on a viewing screen side of the display element and has a scattering central axis in substantially the same azimuth as an azimuth in which a contrast ratio of the display element in a direction inclined by a certain angle from a normal direction of a viewing screen of the display element has an extreme value.

Abstract: The invention aims at providing a display which can improve viewing angle dependency of contrast ratio in a wide azimuth without changing design of a basic structure of a display element, impairing display quality in a direction showing large contrast ratio and being limited to a state of displaying white or black. The aim is attained by a display comprising: a display element having viewing angle dependency of contrast ratio; and an anisotropic scattering film having an anisotropic scattering layer, wherein the anisotropic scattering film has a scattering central axis approximately parallel to a direction showing the largest contrast ratio of the display element and is located on a viewing screen side of the display element.

Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.
