摘要： To increase an amount of the light that can be used for the display efficiently in the total amount of the emitted light in the liquid crystal display device having the surface lighting device such as the front-light. The light (a) becomes the light component of the linearly polarized light by passing the retardation plate (11a). In the reflective polarizer (11b), only the light (b) that is a component of the polarization axis of the reflective polarizer (11b) passes through the reflective polarizer (11b) to enter into the end portion of the light guide (12). The light that is a component other than the component of the polarization axis of the reflective polarizer (11b) is reflected on the reflective polarizer (11b). The light reflected on the reflective polarizer (11b) changes from the linearly polarized light to the circularly polarized light by passing through the retardation plate (11a). The circularly polarized light (d) is transmitted into the light stick (10) and is reflected on the reflective film in the light stick (10). The reflected light (e) change from the circularly polarized light to the linearly polarized light by the retardation plate (11a). The linearly polarized light (f) passes through the polarization axis of the reflective polarizer (11b) to enter into the end portion of the light guide (12).

摘要： An illumination system (8) comprises an optical waveguide (18) which is made from optically transparent components and has four end faces (10, 10′). A light source (12) whose light is coupled into the optical waveguide (18) via one of the end faces (10) is situated opposite this end face (10). The optical waveguide (18) has a light guide (30). A birefringent layer (36) comprising liquid crystals is provided on the light guide (30) at an exit surface side thereof. A first electrode (40) and a second electrode (44) both have electrical contact with the birefringent layer (36) and are connected to a voltage generator (46). By varying the voltage applied between the electrodes (40, 44), the birefringent properties of the birefringent layer (36) comprising the liquid crystals may be varied to control the direction of light coupled out via the exit surface (16).

摘要： A side-lit illumination arrangement comprises a polarized-light-emitting waveguide comprising a polarization-selective beam-splitting interface formed at an interface of a waveguiding layer and a polarization-selection layer. In order to avoid alignment problems occurring during the manufacture of the waveguide which impair the proper functioning of the polarization-selective beam-splitting interface, the polarization-selective beam-splitting interface is planar. Waveguided light polarized and transmitted by the polarization-selective beam-splitting interface into the polarization-selection layer is coupled out by a relief-structured surface via an exit surface. Display devices having such waveguides, in particular if used in a front light, have a high brightness and efficiency.
