PURPOSE:To remove a dot noise and obtain an image which is high in mental evaluation value by constituting a phase structure arranged between a display body and a viewer, by synthesizing plural mutually different phase distributions. CONSTITUTION:This device is equipped with the dot matrix display body and the phase structure body 203 arranged between the display body and viewer, and the phase structure body 203 is formed by synthesizing plural mutually different phase distributions. The liquid crystal display body 202 is lighted by a back light 201 and light which is transmitted through the liquid crystal display body 202 reaches the observer 205 through the phase structure body 203 and a lens 204. In this case, the observer 205 views a virtual image of a liquid crystal display image at a clear vision position through the operation of the lens 204. The liquid crystal display body 202 is a TFT(thin film transistor) drive type color liquid crystal display body. Thus, the phase structure body 203 composed of plural phase distributions is used as an optical band-pass filter. |
