PROBLEM TO BE SOLVED: To provide a display device which can perform, with a simpler structure, switching between naked-eye 3D image display by a parallax barrier method and 2D image display without a decrease in resolution.SOLUTION: In order to reduce manufacturing cost by reducing the number of polarizing plates, a light-shuttering portion including a polymer-dispersed liquid crystal which does not need a polarizing plate is used as a parallax barrier. Further, a light source portion serving as a backlight is formed using a light source including an EL element which forms a planar light source and does not need a diffusion plate. Furthermore, as the light source portion serving as the backlight, a plurality of EL elements are provided so that the plurality of EL elements are selectively controlled and thus selective light emission is performed.

PROBLEM TO BE SOLVED: To make it possible to perform favorable stereoscopic display.SOLUTION: Provided are a display unit 1 and a barrier element 2 disposed on a back side of the display unit 1. The barrier element 2 includes slit portions 22 for emitting light beams for image display toward the display unit 1. The plurality of slit portions 22 are arranged in a lateral direction at intervals. The plurality of slit portions 22 are arranged so that the intervals in the lateral direction (barrier pitch) are narrowed from a center portion to peripheral portions. The arrangement intervals in the lateral direction of the slit portions 22 are optimized so as to compensate for optical positional deviation of the slit portions 22 caused by refraction index difference of two layers (an air layer 4 and a substrate 21) different in reflective index between the display unit 1 and the slit portions 22.

PROBLEM TO BE SOLVED: To provide an image display device capable of reducing color unevenness and luminance unevenness during display of a normal image.SOLUTION: The image display device includes: a transmission type display panel; an illumination part; an optical separation part which includes a plurality of opening/closing parts switchable to a light transmitting state or a light shielding state and separates an image displayed on the transmission type display panel by bringing a prescribed opening/closing part into the light transmitting state and bringing the other opening/closing part into the light shielding state; a light control part capable of switching between a light scattering state and the light transmitting state; and a drive part for driving the transmission type display panel, the optical separation part, and the light control part. The light separation part is disposed between the transmission type display panel and the illumination part, and the light control part is disposed between the optical separation part and the transmission type display part. When an image for a plurality of view points is displayed on the transmission type display panel, the light control part is brought into the light transmitting state, and when an image for a single view point is displayed on the transmission type display panel, the light control part is brought into the light scattering state.
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-view display configured so that different viewers can view different scenes. SOLUTION: A spatial optical modulator 20 includes a black mask wherein at least two portions 72 and 73 having different widths are included between apertures of horizontally adjacent pixels. A parallax barrier 21 includes a plurality of parallax elements cooperating with individual groups of the pixels L and R. The width 70 of each portion 72 of the black mask between the pixels L and R of the same group is larger than the width 71 of each portion 73 of the black matrix between the pixels L and R of different groups.
