To provide an image display device which suppresses the decrease in luminance of display and double reflection without depending on an angle between an absorption axis of a polarizer and a slow axis of a molded body of a plastic resin.SOLUTION: Disclosed is an image display device 100 which includes: a display 12; and a polarizing plate 18 arranged between the display 12 and a projection part 20. The polarizing plate 18 has a polarizer 34, and at least one of a first support plate 30 and a second support plate 38 for supporting the polarizer 34, and the phase difference between the first support plate 30 and the second support plate 38 is n (n is an integer) times of a wavelength of light outputted from the display 12 ±15%.SELECTED DRAWING: Figure 1
【課題】偏光子の吸収軸とプラスチック樹脂の成型体の遅相軸との角度に依存せず、表示の輝度低下や二重映りを抑制した画像表示装置を提供する。【解決手段】表示器12と、表示器12と投影部20との間に配置された偏光板18と、を備え、偏光板18は、偏光子34と、偏光子34を支持するための第1支持板30及び第2支持板38の少なくとも1つを有し、第1支持板30及び第2支持板38の位相差は表示器12から出力される光の波長n倍(nは整数)±15%である画像表示装置100とする。【選択図】図1
