Title (EN) PLASMA DISPLAY PANEL AND FIELD EMISSION DISPLAY
(FR) ÉCRAN À PLASMA ET ÉCRAN À ÉMISSION PAR EFFET DE CHAMP
Abstract:
(EN) It is an object to provide a plasma display and a field emission display that each have high visibility and an anti-reflection function that can further reduce reflection of incident light from external. Reflection of light can be prevented by having an anti-reflection layer that geometrically includes a plurality of adjacent pyramidal projections. In addition, a plurality of hexagonal pyramidal projections, each of which is provided with a protective layer formed of a material having a lower refractive index than a refractive index of the pyramidal projection so as to fill a space among the plurality of pyramidal projections, can be provided to be packed together without any spaces. Further, six sides of a pyramidal projection face different directions with respect to a base. Therefore, light can be diffused in many directions efficiently.
(FR) La présente invention a pour but de fournir un écran à plasma et un écran à émission par effet de champ qui ont chacun une visibilité élevée et une fonction antireflet qui est en mesure de réduire ultérieurement la réflexion de la lumière incidente provenant de l'extérieur. La réflexion de la lumière peut être empêchée en ayant une couche antireflet qui inclut géométriquement une pluralité de saillies pyramidales adjacentes. En outre, une pluralité de saillies pyramidales hexagonales, chacune desquelles est munie d'une couche protectrice formée d'un matériau possédant un indice de réfraction inférieur à l'indice de réfraction de la saillie pyramidale de manière à remplir un espace parmi la pluralité de projections pyramidales, peut être prévue de manière à être regroupée sans aucun espace. En outre, six côtés d'une saillie pyramidale sont orientés dans différentes directions par rapport à une base. Par conséquent, la lumière peut être diffusée dans de nombreuses directions de manière efficace.
