Abstract: Light L1 emitted by a light source unit 2 is non-polarized. The light L1 is transmitted by a phase modulation element 4 to be non-polarized light L2 and enters a polarization separation element 6 which transmits light polarized in a first polarized direction and reflects light polarized in a second polarized direction normal to the first polarized direction. The polarization separation element 6 transmits first linearly polarized light L3 and reflects second linearly polarized light L4 whose polarized direction is normal to the linearly polarized light L3. The linearly polarized light L3 goes to a light guide plate not shown. The linearly polarized light L4 enters a phase modulation element 4 to be transformed to circularly polarized light L5, and circularly polarized light L5 returns to the light source unit 2. The light L5 which has returned to the light source unit 2 repeats reflections, etc. in the light source unit 2 to be again non-polarized light L1 and exits the light source unit 2. As described above, a half of the light, i.e., the first linearly polarized light L3 is transmitted by the polarization separation element 6 to propagate to the light guide plate, and the rest of the light, i.e., the second linearly polarized light returns again to the light source unit 2. This process is repeated, whereby almost all light emitted by the light source unit 2 enters the light guide plate to be utilized.

Abstract: A substrate made of glass serves both as a substrate for a touch panel and as that for a front light, and has both functions of propagating an ultrasonic wave in order to detect a touched position, and propagating light emitted from a light source to guide the light toward a reflective-type liquid crystal display. In the case where an image on the liquid crystal display is made visible by external light, external light which has been transmitted through the substrate is reflected by the liquid crystal display, and the reflected light is again transmitted through the substrate to be emitted from the front face. In the case where the front light function is used, light which has been introduced into the substrate from the light source is reflected by the liquid crystal display, and the reflected light is transmitted through the substrate to be emitted from the front face.

Abstract: An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.
