Zusammenfassung:	With this display apparatus, it is possible to switch between a mode wherein a movable shield plate closes a hole formed in a reflecting plate that reflects light from backlights which provide light from behind a liquid crystal panel that displays an image, and a mode wherein the hole is open. A color sensor arranged behind the reflecting plate detects information pertaining to the light from the backlights that has passed through the hole formed in the reflecting plate. Thus, it is possible to detect information pertaining to the light from the backlights from behind the reflecting plate with high precision, and to improve the appearance viewed from the display-surface side of the apparatus.
