Abstract
An optical filter and a plasma display panel (PDP) employing the same, where the optical filter includes a substrate and a selective absorption layer having a maximum transmittance of about 50% or less in a wavelength range of from about 450 nm to about 680 nm, and wherein a difference between a maximum transmittance and a minimum transmittance at about 450 nm, about 530 nm, and about 630 nm is about 10% or less.
Claims16
An optical filter, comprising:
- a substrate;
- and
- a selective absorption layer having a maximum transmittance of about 50% or less in a wavelength range of from about 450 nm to about 680 nm, wherein a difference between a maximum transmittance and a minimum transmittance at about 450 nm, about 530 nm, and about 630 nm is about 10% or less.
An optical filter, comprising:
- a substrate;
- and
- a selective absorption layer having a difference of about 10% or more between a maximum transmittance and a minimum transmittance in a wavelength range of from about 450 nm to about 680 nm, and a difference of about 10% or less between a maximum transmittance and a minimum transmittance at about 450 nm, about 530 nm, and about 630 nm.
A plasma display panel, comprising:
- a front substrate parallel to a rear substrate;
- a plurality of electrodes between the front and rear substrates;
