Abstract: An optical-path-switching apparatus according to the present invention includes a reducing optical system capable of guiding signal light and control light along the direction of gravity into a thermal-lens-forming optical element having an incidence plane positioned to be perpendicular to the direction of gravity in such a way as to differentiate respective convergence points in a direction perpendicular to the optical axis. The apparatus further includes a light-receiving unit configured to converge or condense straight-traveling signal light in the absence of irradiation with the control light and signal light whose optical path has been switched due to irradiation with the control light using the same optical element. Further, the apparatus includes a wedge-type prism provided at a passing position of the optical-path-switched signal light to increase the distance between the optical axis of the optical-path-changed signal light and the optical axis of the straight-traveling signal light.

Abstract: The present invention provides for improved contrast in the transmissive mode of a transflective liquid crystal display having a rear stack polarizing means (302) which is transmissive for light having a desired polarization and reflective for light having an opposite, undesired polarization. The contrast is improved due to enhancements of the black state provided by the inclusion of a reflection preventing means (306). The reflection preventing means is arranged between the transflector (301) and the rear stack polarizer (302), and serves to stop light transmitted through the rear stack polarizer (302) towards the transflector (301) from being reflected by the transflector (301) back to the rear polarizer (302). Thereby undesired reflections having wrong polarization are stopped from being transmitted through the transflector (301) and thus from affecting the transmissive mode black state of the display.
