<p>A filter for a plasma display panel provided with an antireflection optical film having a color correction function, whereby when red light emitted from the plasma display panel is passed therethrough, the positional relation of the position before the passage and the position after the passage in the CIE xy chromaticity diagram of the red light, satisfies at least one of the following formulae (1) and (2) relating to changes in coordinates x,y, and the following formulae (3) and (4) relating to distances from standard values:
Formulae relating to coordinates x,y:Δx>0.003Δy<-0.003 where Δx is the change in coordinate x, and Δy is the change in coordinate y,Formulae relating to distances from standard values:ΔD(rn)<-0.003ΔD(rc)<-0.003 where ΔD(rn) is the change in the distance from a point (x, y)=(0.67, 0.33), and ΔD(rc) is the change in the distance from a point (x, y)=(0.64, 0.33), and ΔD(rn) and ΔD(rc) respectively mean that when they take positive values, the distances become long, and when they take negative values, the distances become short.</p> |
