Abstract

A display device including a display part including a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, the pixels of the first series and the pixels of the second series being arrayed alternately in each of a horizontal direction and a vertical direction, and a light beam control part that controls a light beam from the display part or a light beam toward the display part.

What is claimed is: 
     
         1 . A display device comprising:
 first-series pixels including a first first-series pixel and a second first-series pixel;   second-series pixels including a first second-series pixel arranged between the first first-series pixel and the second first-series pixel in a first direction;   lenses including a first lens opposed to the first first-series pixel, the second first-series pixel, and the first second-series pixel,   wherein, in a first display mode,
 the first first-series pixel is configured to display a first image corresponding to a first viewpoint, and the first image of the first first-series pixel is radiated to the first viewpoint through the first lens, 
 the second first-series pixel is configured to display a second image corresponding to a second viewpoint, and the second image of the second first-series pixel is radiated to the second viewpoint through the first lens, and 
 the first second-series pixel is configured to display a black color or a gray color. 
   
     
     
         2 . The display device according to  claim 1 , wherein, in a second display mode, the first first-series pixel, the second first-series pixel, and the first second-series pixel are configured to display a common image corresponding to the first viewpoint and the second viewpoint. 
     
     
         3 . The display device according to  claim 2 , wherein:
 the common image corresponds to a 2D image, and   the first image and the second image correspond to a 3D image.   
     
     
         4 . The display device according to  claim 1 , wherein the first lens is a lens with a fixed refraction index. 
     
     
         5 . The display device according to  claim 1 , wherein the first lens is a liquid crystal lens or a liquid lens. 
     
     
         6 . The display device according to  claim 1 , wherein a distance between the first first-series pixel and the second first-series pixel in the first direction is substantially equal to a width of the first first-series pixel in the first direction. 
     
     
         7 . The display device according to  claim 1 , wherein a distance between the first first-series pixel and the second first-series pixel in the first direction is shorter than a width of the first first-series pixel in the first direction. 
     
     
         8 . The display device according to  claim 1 , wherein a distance between the first first-series pixel and the second first-series pixel in the first direction is larger than a width of the first first-series pixel in the first direction. 
     
     
         9 . The display device according to  claim 1 , wherein:
 the first-series pixels further include a third first-series pixel,   the second-series pixels further include a second second-series pixel, and   the second second-series pixel is arranged between the first first-series pixel and the third first-series pixel in a second direction which crosses the first direction.   
     
     
         10 . The display device according to  claim 9 , wherein a central coordinate in the first direction of the first first-series pixel is equal to a central coordinate in the first direction of the second second-series pixel. 
     
     
         11 . The display device according to  claim 1 , wherein the first lens extends in a second direction which crosses the first direction. 
     
     
         12 . The display device according to  claim 1 , further comprising an illuminator, wherein the first-series pixels and the second-series pixels are present between the illuminator and the lenses. 
     
     
         13 . The display device according to  claim 1 , further comprising an illuminator, wherein the lenses are present between the illuminator and both the first-series pixels and the second-series pixels. 
     
     
         14 . The display device of  claim 1 , wherein, for a given group of four neighboring first-series pixels, two of the neighboring first-series pixels display a same first color and two of the neighboring first-series pixels display a same second color. 
     
     
         15 . The display device of  claim 1 , wherein, in a second display mode, the first second-series pixel is configured to display a same color with at least one of the first first-series pixel or the second first-series pixel. 
     
     
         16 . The display device of  claim 1 , wherein:
 the first series pixels further include a third first-series pixel,   the second series pixels further include a second second-series pixel,   the second second-series pixel is arranged between the first first-series pixel and the third first-series pixel in a second direction which crosses the first direction, and   in a second display mode, the second second-series pixel is configured to display a same color with the first first-series pixel.
