A 3-dimensional displaying apparatus includes an image displaying panel having a plurality of pixels and a backlight panel spaced apart from one surface of the image displaying panel. The backlight panel includes a first line source set having a plurality of line sources arranged at regular intervals and a second line source set having line sources arranged spaced apart from the respective line sources of the first line source set by a predetermined interval. The first line source set and the second line source set are driven alternately. Thus, in a case where a horizontal location of an observer varies, the change of brightness of image information and the crosstalk between adjacent visual fields are minimized, and pseudo-stereoscopic vision is prevented. Also, the irregularity of brightness distribution in a visual field may be solved.

An autostereoscopic 3D image display device using time division is provided. The image display device includes a backlight, an image display panel, a controller, and a viewer position tracking system. The backlight includes a plurality of line sources which are disposed at certain intervals. The image display panel displays a 3D image. The controller controls the backlight and a viewing point image of the image display panel. The viewer position tracking system determines a pupil position of a viewer and transfers position information to the controller. The image display panel provides two or more viewing points. The line sources configure two or more line source sets that are separately driven at the same time. The two or more line source sets are sequentially driven.
