Embodiment Construction
[0035] Such as Figure 4 As shown, the traditional light-transmitting DHF unit 201 has a layer of S with thickness d C * Layer 202, which is arranged between two mutually parallel sheets of transparent material 203 and 204. Suitable transparent materials for the parallel sheets 203 and 204 are, for example, glass, acrylic glass or plastic films.
[0036]The polarizer 205 is located on the outside of the upper layer 203, and is preferably connected to the layer 203, for example, glued together with the layer. Correspondingly, a polarizer 206 is similarly assigned to the lower layer 204, which in the embodiment shown acts as an analyzer when light is incident from above and passes through the cell. In the reflective cell configuration, the second polarizer 206 is not required. If light is incident from below, the first polarizer 205 is not needed. Instead of the omitted polarizer, unit 201 has a light reflector or a diffuse reflector.
[0037] The liquid crystal layer 202 ...
