A 3-dimensional image display device having wide viewing angles using Fresnel lenses is disclosed. According to an embodiment of the invention, the 3-dimensional image display device includes an image source providing part for providing an image source, a first Fresnel lens refracting and transmitting the image source that is incident from the image source providing part, and a second Fresnel lens for generating a 3-dimensional image by refracting and transmitting the image source transmitted from the first Fresnel lens. At least one of the first Fresnel lens and the second Fresnel lens is a curved type Fresnel lens surface. The present invention can maximize the display area for a 3-dimensional image and realize the 3-dimensional image having wide viewing angles without distortion on the left and right boundaries.
