ABSTRACT:
A display device for selectively displaying any one of 2D and 3D images with a capacity of displaying the 3D image with the same resolution as that of the 2D image. The display device includes a light source radiating white colored light, and an image display unit receiving the light from the light source to display the desired images. A beam splitter is placed between the light source and the image display unit to split the light radiated from the light source in the directions of left and right eyes of the user, and feed the split light rays to the image display unit. An optical shutter is provided at any one of front and rear surfaces of the beam splitter. The optical shutter has a plurality of shutter members with variable light transmittance to control the light transmission such that at least one of the two-directional light rays split at the beam splitter reaches the user.
