Embodiment Construction

[0069] In the present invention, for example, in the semi-transmission three-dimensional image display device, the pixels for the left eye and the pixels for the right eye are arranged periodically or in the arrangement direction of the cylindrical lens in the double-sided lens, or Arranged in the same direction as the slits in the parallax barrier. Each pixel includes a transmissive area and a reflective area. Further, the transmissive area and reflective area in each pixel are arranged periodically or in the length direction of the cylindrical lens in the double-sided lens, or in the length direction of the slit in the parallax barrier.

[0070] According to this structural arrangement, it is obtained that the light emitted from the pixel for the left eye and the light emitted from the pixel for the right eye are deflected toward the direction of the left eye or the right eye, but in each pixel from the transmitted The light emitted from the region and the light emitted fro...

Abstract

First pixels for the left eye and second pixels for the right eye in the semi-transmissive liquid crystal display panel are alternately disposed in the array direction of cylindrical lenses in a lenticular lens. A first transmissive region and a first reflective region are disposed in the first pixel for the left eye, and a second transmissive region and a second reflective region are disposed in the second pixel for the right eye. In this case, the first transmissive regions and the second reflective regions in the first pixels are alternately disposed and the second transmissive regions and reflective regions in the second pixels are alternately disposed in the longitudinal direction of the cylindrical lenses.

Description

technical field [0001] The present invention relates to an image display device capable of displaying different images toward a plurality of observation points, a portable terminal device in which such an image display device is installed, and a display panel installed in such an image display device, and more Specifically, the present invention relates to an image display device, a portable terminal device and a liquid crystal display panel, all of which can reduce power consumption. Background technique [0002] Now, much research has been done on display devices capable of displaying three-dimensional images. Regarding binocular observation, the Greek mathematician Euclid stated in 280 BC: "Binocular observation is the vision obtained when a person watches two different images with his left and right eyes at the same time. An image is obtained by viewing an object from different directions." (See, for example, the article "Three-Dimensional Display" by Chihoro Masuda, Sa...
