Title:
プラズマディスプレイパネル
Document Type and Number:
Japanese Patent JP5442197
Kind Code:
B2
Abstract:
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.
