The Depth-Fused 3-D (DFD) display system developed in NTT, which does not require users to wear special glasses, shows images on front and rear screens. The images enable observers to feel a good sense of depth directly in front of the display. However, when the display is observed from an oblique angle, the images become double images, the feeling of depth is lost, and sense of discomfort increases. This paper presents a method of comfortably presenting solid 3D characters and symbols, which has been applied for both electronic displays and printing. By utilizing a stacked display and a gradation effect in the front and rear images, the image doubling is well suppressed even when seen from an oblique angle. A subjective evaluation experiment was conducted to investigate the conditions for creating contents that can be seen comfortably from an oblique angle.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.134 No.10 （2014） 特集：インタラクティブ映像メディアの最前線本誌掲載ページ: 1443-1450 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/134/10/134_1443/_article/-char/ja/
