Abstract
A liquid crystal display device includes first and second display units for controlling transmission and interception of a light incident upon a front side on an observation side of display, whose rear surfaces are disposed to face each other in reverse directions, and an irradiation member. The member including an illumination device for generating a light from opposite surfaces is disposed between two polarized-light split elements between the display units and which reflects a light of a polarized-light components transmitted through one of the polarized-light split elements by the other polarized-light split element and reflects a light of the polarized-light component transmitted through the other polarized-light split element by the one reflective polarized-light split element to irradiate the first and second display units with the light.
