摘要： An illumination panel comprises a light source, a photoconductor for guiding light from the light source, and an optical film for emitting light emitted from the photoconductor ahead of an observer. The photoconductor comprises a stepwise face having an incident end face onto which the light from the light source is projected, step faces, and step differentiating faces for emitting the light guided from the light source and connecting the step faces, and reflective films formed on the step faces. The optical film is arranged at the front side of the photoconductor, and has projected incident portions which are opposite to the step differentiating faces in a light emitting direction. The optical film emits the light emitted from the step differentiating faces ahead, and causes the light that is projected from the front to be reflected ahead on reflective faces on the step faces. In the incident portions, one of side faces opposite to the step differentiating faces of the photoconductor makes an incident face for receiving the light emitted from the step differentiating faces, and the other makes a refractive face for reflecting/refracting the light taken in the incident face toward its front face. A liquid crystal display element is arranged at the front of this illumination panel so that they constitute a liquid crystal display device.

摘要： A light beam emitted by a surface illuminant reaches the surface of a transparent base layer of a recess/projection detection optical element. A light beam emitted almost vertically is emitted to an air layer. A light beam incident on the transparent base layer at an angle larger than a total reflection angle returns to a two-dimensional photosensor at a portion contacting the air layer, but scatters in a transparent particle at a portion contacting the transparent particle. When a finger is brought into contact with a scattering reflection layer, the scattering reflection state does not change in an area corresponding to a valley of a fingertip. As indicated by an arrow, an amount of reflected light beam is large. In an area corresponding to a ridge of the fingertip, the light beam scattered by the transparent particle is absorbed. The amount of reflected light beam is small, as indicated by an arrow. An image having bright and dark portions optically emphasized in correspondence with the valley and ridge of the fingertip of the finger can be obtained.

摘要： A surface light source includes a prism sheet placed on one side of a liquid crystal display panel, and having elongated prism portions formed to form a patterned indented entrance surface having an angular cross-section, and an exit surface. A reflecting plate is placed to face the prism sheet through a space. First and second light source units are disposed on two end sides. A control unit sequentially writes left-eye image data and right-eye image data on respective pixels of the display panel, causes the light source unit on the right side when viewed from an observation side of the surface light source to emit light in synchronism with the writing of the left-eye image data, and causes the light source unit on the left side to emit light in synchronism with the writing of the right-eye image data.

摘要： On a side opposite to an observation side of a liquid crystal display panel, a plane light source is disposed which emits an illuminative light for the left eye of three colors of red, green and blue having such a directivity that a peak of emitted light intensity exists in a direction of the observer's left eye, and that for the right eye of three colors of red, green and blue having such a directivity that the peak of emitted light intensity exists in a direction of the right eye. A control unit selects unit color image data of three colors of red, green and blue for the left eye and that of three colors of red, green and blue for the right eye in an optional order to successively write the data in each pixel of the liquid crystal display panel in one frame for displaying a three-dimensional image including images for the right and left eyes, so that an illuminative light having color and directivity corresponding to the written unit color image data is emitted from the plane light source in synchronization with the writing of the unit color image data.
