ABSTRACT:
The embodiment is to make it possible to increase a resolution obtained when a character or a two-dimensional image is displayed. A stereoscopic image display device is provided with a two-dimensional image display device having a plurality of pixels arranged within a display plane; and a ray control section which is provided in front of or behind the display plane and has a plurality of opening portions or a plurality of lenses arranged side by side, for controlling rays from the pixels, a distance z from the ray control section to a two-dimensional character or a two-dimensional image display position satisfying relationships ofin-line-formulae description="In-line Formulae" end="lead"?0<z<L×D/(1+D)/2 in a projection region andin-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?0<z<L×D/(1−D)/2 in a depth region,in-line-formulae description="In-line Formulae" end="tail"?wherein L represents a viewing distance, Ip represents a pitch of the opening portions or the lenses,2θ represents a viewing area angle, pprepresents the pitch of the pixels, and D is expressed asD=(lp)22⁢Lpp⁢tan⁡(θ).
