Display device and optical filter

A display device having a plasma display panel, comprising:

• an optical filter having a blind sheet that comprises
• a plurality of semitranslucent layers having translucence arranged side-by-side and each extending in a horizontal direction and each having a taper whose thickness that decreases as the distance from the plasma display panel increases, and
• a plurality of transparent layers each being disposed between the semitranslucent layers and each being of a higher translucency than that of the semitranslucent layer and of a greater thickness than the thickness of the semitranslucent layer;
• and
• an adhesive member for sticking the optical filter to the plasma display panel,
• wherein a ratio of transmittance at a screen limit angle with respect to transmittance of the optical filter at a center of the plasma display panel is at least 0.10 and not more than 0.50,
• wherein the optical filter further has
• an electromagnetic wave blocking layer laminated on the transparent layers of the blind sheet and
• a color-tone correcting layer laminated on the electromagnetic wave blocking layer.
