Claim 0:
1. An electronic apparatus comprising:
a liquid crystal display panel that has a different transmission wavelength characteristics depending on a viewing direction and uses a backlight and reflection of an external incidence ray as light sources;
a backlight unit that is set in an illumination mode in which the backlight is illuminated or a non-illumination mode in which the backlight is not illuminated; and
a display controller that displays information on the liquid crystal display panel by setting one of a shielding region which shields the backlight and the external incidence ray and a transmission region which transmits the backlight and the external incidence ray as an information display region and setting the other one as a background region,
wherein the display controller performs first display control in which a region having a larger area of the information display region and the background region is set as the shielding region and a region having a smaller area is set as the transmission region, and performs second display control in which the region having the larger area of the information display region and the background region is set as the transmission region and the region having the smaller area is set as the shielding region,
wherein the information to be displayed is limited to characters, numbers, symbols, and figures,
wherein the information is displayed in binary tone, and
wherein the display controller independently sets the shielding region and the transmission region by controlling each dot of the liquid crystal display panel.
