摘要:
A filter to improve contrast and shield electromagnetic waves, and a plasma display apparatus including the filter. The filter includes a base film, a first color pattern unit having strips disposed in parallel, at predetermined intervals, on both surfaces of the base film, and a second color pattern unit formed on one or both of the surfaces of the base film. The first color pattern unit and the second color pattern unit are conductive, and intersects one another.

Provided is a filter for a plasma display panel and a plasma display apparatus having the filter. The filter that is attached to a front surface of the plasma display panel that includes a first and second substrates facing each other and a barrier rib structure that is disposed between the first and second substrates and comprises a plurality of first barrier ribs and second barrier ribs that define a plurality of discharge cells by crossing each other. The filter comprises a base film, and a plurality of pattern portions disposed on a surface of the base film and extending in a direction crossing the second barrier ribs. The pattern portions have a pitch of approximately 15% of the vertical length of the discharge cells.

A liquid crystal display (LCD) having color filters configured according to optical characteristics of a field emission backlight. The LCD includes: a display panel having color filters including red, green, and blue filters; and a backlight device at a rear side of the display panel and including a vacuum panel with a cold cathode electron source and a phosphor layer that is excited by electrons emitted from the cold cathode electron source to emit visible light. Here, a wavelength position corresponding to a half of a peak intensity of a transmission spectrum of the red filter is at from about 570 nm to about 622 nm, a wavelength position corresponding to a half of a peak intensity of a transmission spectrum of the blue filter is not greater than 520 nm, and/or a transmission spectrum of the green filter has a full width at half maximum (FWHM) ranging from about 60 nm to about 115 nm.
