摘要:
A display device provided with a screen, comprising: an optical filter having a blind sheet that comprises a plurality of semitranslucent layers having translucence arranged side-by-side extending in a horizontal direction and having a predetermined thickness in a vertical direction, and a plurality of transparent layers which are disposed between the semitranslucent layers and which are of a higher translucency than that of the semitranslucent layers and of a greater thickness than the thickness of the semitranslucent layers; and an adhesive member for sticking the optical filter to the screen, wherein the ratio of the transmittance of a limit angle of the screen with respect to the transmittance of the optical filter at the center of the screen is at least 0.10 and not more than 0.50.
