3D IMAGE DISPLAY APPARATUS

摘要

PURPOSE: A three-dimensional image display device is provided to broaden a viewing angle by widening the light emitting angular range of light. CONSTITUTION: A three-dimensional image display device(10) includes a light emitting unit(20), an active prism array(50), and a display panel(70). A light emitting unit includes a plurality of cells. A light emitting direction of a light is especially controlled in a plurality of cells. The active prism array is equipped on the light output unit. The prism unit is arranged in a plurality of the cells. The active prism array controls the inclination of a refracted side of the prism unit according to an electric signal. The display panel modulates a light which penetrates the active prism array according to an image signal.
