ABSTRACT:
Disclosed is a front filter attached to a front surface of a plasma display panel, the front filter comprising: an antireflection coating for preventing reflection of incident light from outside; an optical characteristic film for improving optical characteristics of incident light from the panel, by decreasing brightnesses of red (R) and green (G) rays and by increasing brightness of blue (B) rays; an EMI shielding film for shielding emission of electromagnetic wave; and an NIR blocking film for blocking near infrared rays emitted from the panel, wherein, transmittance of emitted light from the plasma display panel when the emitted light transmits the antireflection coating, the optical characteristic film, the EMI shielding film, and the NIR blocking film is determined in dependence of wavelength of the emitted light, and wherein transmittance of B rays at a wavelength of 454 nm is 50–80%, transmittance of G rays at a wavelength of 525 nm is 40–80%, transmittance of orange rays at a wavelength of 580–592 nm is 5–30%, transmittance of R rays at a wavelength of 610–630 nm is 50–80%, and transmittance of NIR at a wavelength of 850–950 nm is 1–10%.
