Claims

[Scope of Claim for Utility Model Registration] (1) A transmissive liquid crystal display panel that displays image data, a backlight section provided on the back of this liquid crystal display panel, and a printout of the image displayed on the liquid crystal display panel. an instant film provided on the front surface of the liquid crystal display panel to which an image displayed on the liquid crystal display panel is exposed by lighting the back light section; An image printer comprising: a control means for synchronously lighting up the backlight part for one screen during the effective screen display period of the image to be displayed. (2) The above-mentioned liquid crystal display panel is composed of a color liquid crystal panel that displays R, G, and B image data, and the above-mentioned backlight section
, B R, G, B of the pattern corresponding to each display pixel
The control means has a light source section, and the control means controls an effective screen display period n (n≧3) of the image on the liquid crystal display panel in response to the instruction means.
While R, G, and B data are displayed at different timings within the screen, the R of the backlight section is adjusted to match the display timing of the R, G, and B data.
2. The image printer according to claim 1, wherein the light sources , G, and B are turned on at different timings.
