The write light 50 emitted from the light source 43 of 42 to the display medium 11 is adjusted so as to be focused on any one of the plurality of photoconductive layers 22A, the photoconductive layer 22B, and the photoconductive layer 22C of the display medium 11. To do. For this reason, image quality deterioration due to the aberration of the image displayed on the display medium 11 is suppressed. [Selection] Figure 2 |
