As such, the left eye image will be brighter than the right eye image, thereby causing the Moiré BACKGROUND OF THE DISCLOSURE 1SSC. 0001 1. Field of the Disclosure 0007 FIGS. 1C and 2C show why the Moiré issue occurs 0002 The disclosure relates to 3D image display devices, when the viewer and the 3D image display device are too far and in particular relates to a light shielding element of pixels apart. As shown in FIG. 1C, the right eye R will see 3D of 3D image display devices. aperture areas (first area) 23R on the right eye pixels 12R, and 0003 2. Description of the Related Art the left eye L will see the other 3D aperture areas (second 0004. A barrier type 3D image display device may show area) 2.3L on the left eye pixels 12L. As shown in FIG. 2C, the 3D images as shown in FIG. 1A. An image display device, 3D aperture area (first area) 23R on the right eye pixel 12R is e.g. LCD, includes an array substrate 11, a color filter sub located in the left portion of the right eye pixel 12R, and the strate 13, and a liquid crystal layer 14 disposed therebetween. 3D aperture area (second area) 23L on the left eye pixel 12L A plurality of right eye pixels 12R and left eye pixels 12L are is located in the right portion of the left eye pixel 12L. The 3D staggered arranged to construct a pixel layer 12 on the array aperture area (first area) 23R on the right eye pixel 12R is not substrate 11. A polarizer 15, a glue layer 17, a glass layer 19, shielded by the light shielding element 25, and the 3D aper and a 3D barrier 21 are sequentially disposed on the color ture area (second area) 2.3L on the left eye pixel 12L is almost filter substrate 13. The 3D barrier 21 includes openings 21A shielded by the light shielding element 25. As such, the right disposed between light barriers 21B, and the openings 21A eye image will be brighter than the left eye image, thereby substantially align with interfaces of the right eye pixels 12R causing the Moiré issue. and left eye pixels 12L. As shown in FIG. 1A, a right eye R of 0008. The Moiré issue does not only occur in the barrier a viewer sees right eye images from the right eye pixels 12R type 3D image display devices, but also in the lenticular lens through the openings 21A of the 3D barrier 21, and a left eye type 3D image display devices. A lenticular lens type 3D L of the viewer sees left eye images from the left eye pixels image display device may show 3D images as those shown in 12L through the openings 21A of the 3D barrier 21, respec FIG. 3A. An image display device, e.g. LCD, includes an tively. The right eye R will see 3D aperture areas (first areas) array substrate 11, a color filter substrate 13, and a liquid 23R on the right eye pixels 12R, and the left eye L will see the crystal layer 14 disposed therebetween. A plurality of right other 3D aperture areas (second areas) 23L on the left eye eye pixels 12R and left eye pixels 12L are alternately arranged pixels 12L. The right eye images and the left eye images are to construct a pixel layer 12 on the array substrate 11. A combined in the brain of the viewer for 3D image effect. polarizer 15, a glue layer 17, a glass layer 19, and a lenticular 0005 FIG. 2A shows light shielding elements 25 of the lens layer 27 having a plurality of lenses are sequentially right eye pixel 12R and the left eye pixel 12L. The right eye disposed on the color filter substrate 13. Each of the lenses of pixels 12R include a top part as red pixel, a middle part as the lenticular lens layer 27 substantially corresponds to one green pixel, and a bottom part as blue pixel. Similarly, the left right eye pixel 12R and one left eye pixel 12L. As shown in eye pixel 12L includes a top part as red pixel, a middle part as FIG. 3A, a right eye R of a viewer sees right eye images from green pixel, and a bottom part as blue pixel. In FIG. 2A, each the right eye pixels 12R through the lenticular lens layer 27, of the red, green, and blue pixels of the right eye and left eye and a left eye L of the viewer sees left eye images from the left pixels 12R and 12L has a light shielding element 25. The light eye pixels 12L through the lenticular lens layer 27, respec shielding elements 25 are usually active circuits, such as a tively. The right eye R will see the defocused areas (first area) TFT to control brightness of the pixels. As shown in FIG. 2A, 29R on the right eye pixels 12R, and the left eye L will see the the 3D aperture area (first area) 23R on the right eye pixel 12R other defocused areas (second area) 29L on the left eye pixels is located in the middle position of the right eye pixel 12R, 12L. The right eye images and the left eye images are com and the 3D aperture area (second area) 23L on the left eye bined in the brain of the viewer for 3D image effects.
