摘要： In an image display device where a lenticular lens, a display panel, and a light source are provided in order from a viewer side, when cylindrical lenses of the lenticular lens are arrayed in a horizontal direction, in first-viewpoint pixels and second-viewpoint pixels of the display panel, openings whose sides which intersect with straight lines in the horizontal direction are not parallel to a vertical direction are formed. And, a shape of the openings of a pair of pixels mutually adjacent in the vertical direction is made line-symmetric with respect to edges of the pixels extending in the horizontal direction as an axis.

摘要： In a liquid crystal display device, a liquid crystal layer is provided between a principal substrate and an opposing substrate that are disposed so as to face each other, and a shared electrode and a pixel electrode, which is a parallel electrode pair formed in the shape of a comb, are formed on the surface of the principal substrate that faces the opposing substrate. Orientation films are also formed on the opposing surfaces of the principal substrate and the opposing substrate. The electrodes of the parallel electrode pair are formed so that the width thereof is smaller than the thickness of the liquid crystal layer. The orientation of the liquid crystal molecules between the electrodes is thereby changed by an electric field generated by the parallel electrode pair, and the orientation of liquid crystal molecules disposed above the electrodes is changed in the same direction as in the liquid crystal molecules between the electrodes in accordance with the change in orientation of the liquid crystal molecules between the electrodes. A high degree of transmittance can thereby be achieved by a simple electrode structure in an in-plane switching liquid crystal display device.

摘要： In a display device, white LEDs and bluish white LEDs are arranged in alternating fashion on the light-incident surface side of a light-guide plate. On the light-exit side of the light-guide plate is disposed a transparent/scattering switching element switchable between a state of scattering incident light, and a state of transmitting light unchanged without scattering. During a narrow-angle display, only the white LEDs are lit, and the transparent/scattering switching element is placed in the transparent state, while during a wide-angle display, both the white LEDs and the bluish white LEDs are lit, and the transparent/scattering switching element is placed in the scattering state.

摘要： In a display device equipped with a light source device, a second light-guide member is provided to the back surface of a first light-guide member that has an emitted light control sheet provided to the front surface thereof. The emitted light control sheet is composed of a flat plate portion and protrusions. A first light source mounted to a side surface of the first light-guide member, and a second light source mounted to a side surface of a second light-guide member are switched and turned on. The emitted light control sheet has light-condensing effects when the first light source is on, and has diffusing effects when the second light source is turned on. The angle range of illuminating light can thereby be switched.

摘要： A 3D image/2D image switching display apparatus is provided with a liquid crystal display unit and first and second lenticular lenses. To display a 3D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens coincides with the optical axis of the second lenticular lens so that pixels for a left eye display an image for a left eye and pixels for a right eye display an image for a right eye. To display a 2D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens is shifted from the optical axis of the second lenticular lens by half a lens pitch so that the pixels for the left eye and the pixels for the right eye display the same image independently.

摘要： A translucent liquid crystal display panel (2) includes pixel pairs as display units each formed by a left-eye pixel (4L) and a right-eye pixel (4R) and arranged in a matrix shape. A through hole (4Ld) arranged in a color layer (4Lc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of a cylindrical lens (3a) constituting a lenticular lens (3). Similarly, a through hole (4Rd) arranged in a color layer (4Rc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of the cylindrical lens (3a) constituting the lenticular lens (3). This suppresses the phenomenon that a hue is changed by a field-of-view angle and/or an external light condition on the translucent display panel capable of displaying an image directed to a plurality of viewpoints.
