WHITE LIGHT-EMITTING PHOSPHORESCENT SHEET HAVING OVERALL LIGHT-TRANSMITTING PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a white light-emitting phosphorescent sheet suppressing reduction of an emission amount caused by a phosphorescent layer overlaying a light-emitting body.SOLUTION: A white light-emitting phosphorescent sheet disposed on a light-emitting body is provided, in which a plurality of phosphorescent light-emitting groups is formed while leaving a space between the groups on a base sheet. The phosphorescent light-emitting group comprises a combination including at least each one of a red phosphorescent layer having a red phosphorescent pigment singly dispersed in a first holding substrate, a green phosphorescent layer having a green phosphorescent pigment singly dispersed in a second holding substrate, and a blue phosphorescent layer having a blue phosphorescent pigment singly dispersed in a third holding substrate; and the red phosphorescent layer, the green phosphorescent layer and the blue phosphorescent layer are formed on the same plane.SELECTED DRAWING: Figure 1
