Abstract: A display device includes: a mirror body; a display component; and a mirror component disposed between the mirror body and the display component and switchable between a transmitting state in which external light and picture light are transmitted and a reflecting state in which the external light passing through the mirror body is reflected. The mirror body includes: a substrate transparent to light; an absorptive polarizer covering a first region not including the mirror component or the display component and a second region including the mirror component and the display component in plan view; and a reflective polarizer disposed on a rear face of the substrate and including an opening in the second region. The mirror component includes: a liquid crystal layer capable of changing a polarization direction of the external light; and a reflective polarizer disposed on a side of the liquid crystal layer adjacent to the display component.

Abstract: An image display device includes a display panel which displays an image, a back cover disposed along the back surface of the display panel, a circuit substrate which is disposed on the back surface of the back cover and which is for driving the display of the image on the display panel, and a FPC which connects the circuit substrate and the display panel. The back cover has a recess recessed inward from the edge of the back cover in a plan view. The FPC is disposed so as to pass through the recess.

Abstract: Provided is an image display device including: liquid crystal cell; light guide plate that is disposed behind liquid crystal cell and is quadrilateral-shaped; light source that extends along at least one end face of light guide plate and emits light toward the at least one end face; reflective sheet that is disposed on a rear face of light guide plate and reflects, toward liquid crystal cell, the light emitted by light source; and a base plate that is disposed on a rear face of reflective sheet and supports reflective sheet, in which reflective sheet includes, at each of positions corresponding to both end portions of light source, protrusion that protrudes toward light source.
