An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:

• a mirror head pivotable about a mirror support;
• wherein said mirror support is configured to attach at an interior portion of a vehicle equipped with said interior rearview mirror assembly;
• wherein said mirror head comprises a mirror casing and a mirror reflective element having a transflective mirror reflector that at least partially reflects light incident thereon and at least partially transmits incident light therethrough;
• wherein said mirror reflective element comprises a reflective region defined by said transflective mirror reflector;
• a video display device disposed behind said mirror reflective element, wherein said video display device comprises a display screen that occupies at least 75 percent of said reflective region of said mirror reflective element;
• wherein said display screen is backlit by a backlighting device, and wherein said backlighting device comprises a plurality of micro-LEDs disposed at a rigid circuit element;
• wherein a width dimension of each micro-LED of said plurality of micro-LEDs is less than 500 microns, and wherein a length dimension of each micro-LED of said plurality of micro-LEDs is less than 500 microns;
• wherein packing density of micro-LEDs of said plurality of micro-LEDs at a substrate of said rigid circuit element is at least 10 micro-LEDs per square centimeter of substrate surface area;
• wherein said display screen and said backlighting device are disposed within said mirror casing and are at least partially retained at a chassis within said mirror casing;
• wherein said chassis comprises a rear wall and side walls extending from the rear wall, and wherein said backlighting device is disposed at the rear wall of said chassis and said display screen is disposed in front of said backlighting device and spaced from said backlighting device by an air gap defined in part by the side walls of said chassis, and wherein depth of the air gap between said backlighting device and said display screen is no more than 3 mm;
• wherein said display screen comprises a film stack having a plurality of layers of diffuser film, and wherein at least one of the plurality of layers of diffuser film comprises a phosphor conversion film;
• wherein, with said mirror support attached at the interior portion of the equipped vehicle, said video display device is operable to display video images captured by a camera of the equipped vehicle;
• and
• wherein, when said video display device is operated to display video images, light emitted by said video display device passes through said mirror reflective element for viewing of displayed video images by a driver of the equipped vehicle viewing said mirror reflective element.
