Embodiment 1

[0126] The liquid crystal display device 1A according to this embodiment is capable of displaying right-eye images and left-eye images. The liquid crystal display device 1A allows the observer to view a three-dimensional image by displaying different images to the observer's right and left eyes.

[0127] as in figure 1 As shown in , a liquid crystal display device 1A is constructed by disposing a lens array sheet 3 composed of a cylindrical lens array on a liquid crystal panel 2 . Furthermore, the backlight 15 is provided on the side opposite to the lens side of the liquid crystal panel 2 .

[0128] The individual cylindrical lenses 3 a constituting the lens array sheet 3 extend along the Y-axis direction and are arranged along the X-axis direction. The cylindrical lens 3a has a lens effect only along the X-axis direction; it does not have any lens effect along the Y-axis direction. In other words, cylindrical lens 3 a functions as an optical unit that distributes light em...

Embodiment 2

[0179] as in Figure 10 As shown in , the liquid crystal display device 1B according to this embodiment is composed of pixels 4Pix each composed of sub-pixels 4S arranged in three rows and two columns. Each sub-pixel 4S has a parallelogram opening. Among the three data lines D1, D2 and D3 which are provided in the sub-pixel 4S and have the same width, the data line D1 is provided on the boundary of the adjacent sub-pixel 4S, and the other two data lines D2 and D3 are equally Divide the opening.

[0180] The storage capacitor line CS is provided for the row of sub-pixels 4S arranged in the X-axis direction parallel to the gate line G. Here, the width of the data line D, the inclination of the data line D and the gate line G, and the distance between the data lines D have the same relationship as described in Embodiment 1 above.

[0181] as in Figure 11 As shown in , the liquid crystal display device 1B is produced in a P-Si (polysilicon) TFT process, and has an undercoatin...

Embodiment 3

[0197] as in Figure 14 As shown in , the liquid crystal display device 1C according to this embodiment is configured to have a plurality of pixel electrodes 4E in sub-pixels 4S. In the liquid crystal display device 1B according to Embodiment 2, the transparent conductive film 77 serving as the pixel electrode 4E is separated based on the sub-pixel 4S. On the other hand, in the liquid crystal display device 1C according to this embodiment, the pixel electrode 4E is divided into three in the sub-pixel 4S.

[0198] as in Figure 15 As shown in , the transparent conductive film 77 is spaced above the data line D in the sub-pixel 4S. Each of the divided pixel electrodes 4E is electrically connected to the P-Si film 72P via the second contact CONT2. The pixel electrode 4E and the P-Si film 72P can be electrically connected via the wiring metal film 76 . As the layout of the CF substrate 22, the liquid crystal display device 1C can adopt not only image 3 pattern shown, but als...

Abstract

Red, green, and blue color resists and a shielding layer (black matrix) are layered on a liquid crystal panel. The subpixels are zoned by the shielding layer. The subpixels arranged in three rows and two columns form a pixel. The red, green, and blue color resists are colored on the basis of a row of subpixels. The color resists extend in stripes in the X-axis direction. Three data lines are provided for each column of subpixels in the manner that one is provide under the shielding layer and the other two diagonally divide the opening of the shielding layer at equal intervals.

Description

[0001] incorporated by reference [0002] This application is based on Japanese Patent Application No. 2012-14232 filed on January 26, 2012 and including specification, claims, drawings and abstract. The disclosure of the above Japanese Patent Application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a liquid crystal display device, and in particular to a liquid crystal display device displaying three-dimensional images. Background technique [0004] Recently, demand for displays capable of displaying three-dimensional images, or so-called 3D images, has been increasing. Methods for displaying three-dimensional images have long been developed. Currently, active research and development efforts are underway. One of the currently most promising approaches exploits the parallax between the eyes. [0005] Three-dimensional display devices utilizing parallax between eyes are classified into two types: one type u...
