Three dimensional image display device
View Patent ↗It is an object to reduce 3D moiré and provide a higher-quality three dimensional image display device. The three dimensional image display device includes a display panel on which rows of pixels for right eye and rows of pixels for left eye are alternately arranged in a lateral direction, the display panel planarly displaying an image for three dimensional display, and a parallax forming liquid crystal panel for forming a parallax in an image for right eye and an image for left eye displayed by the display panel. Lateral direction center positions, which are vertexes of luminance in the lateral direction of an image for right eye and an image for left eye, where the image for three dimensional display is visually sensed through the parallax forming liquid crystal panel, are respectively positions shifted in the lateral direction in different positions in the screen longitudinal direction.
1. A three dimensional image display device comprising:
a display panel on which rows of pixels for right eye and rows of pixels for left eye extending in a screen longitudinal direction are alternately arranged in a screen lateral direction, the display panel planarly displaying an image for three dimensional display using the rows of the pixels for right eye and the rows of the pixels for left eye; and
a parallax forming liquid crystal panel arranged in parallel to the display panel on a display direction side of the display panel and for forming a parallax in an image of the rows of the pixels for right eye and an image of the rows of the pixels for left eye displayed by the display panel, the parallax forming liquid crystal panel comprising an electrode for orienting a liquid crystal,
wherein
lateral direction center positions, which are vertexes of luminance in a lateral direction of an image of the pixels for right eye and an image of the pixels for left eye, where the image for three dimensional display is visually sensed through the parallax forming liquid crystal panel, are respectively positions shifted in the lateral direction in different positions in the screen longitudinal direction,
the electrode is configured to cover a gap between the row of pixels for right eye and the row of pixels for left eye adjacent to each other,
the electrode extends in a first oblique direction with respect to the screen longitudinal direction for a first number of pixels, bends to a second oblique direction opposed to the first oblique direction with respect to the screen longitudinal direction, and extends in the second oblique direction for a second number of pixels, and
the first number is different from the second number.
2. The three dimensional image display device according to claim 1 , wherein the parallax forming liquid crystal panel forms a lenticular lens by orienting liquid crystal and forms a parallax in the image for three dimensional display.
3. The three dimensional image display device according to claim 1 , wherein the parallax forming liquid crystal panel forms a parallax in the image for three dimensional display by orienting the liquid crystal to thereby form a parallax barrier.
