Abstract

An image displaying device includes a planar display panel and a light penetrating unit. The planar display panel displays a plane image. The planar display panel at least includes a first pixel group, a second pixel group and a third pixel group. The second pixel group is located between the first pixel group and the third pixel group. When vision passes through the light penetrating unit toward the planar display panel, the vision acquires a second distance of a second imaging position within the plane image relevant to the second pixel group relative to the planar display panel being greater than a first distance of a first imaging position within the plane image relevant to the first pixel group relative to the planar display panel and a third distance of a third imaging position within the plane image relevant to the third pixel group relative to the planar display panel.

First claim
