Abstract: An image display device includes a display panel that displays an image on a front surface; a light guide plate that is disposed on a rear surface of the display panel; a support plate that supports the light guide plate, and extends beyond at least one lateral surface of the light guide plate in a front view of the light guide plate; a light-emitting diode (LED) unit that emits light into an incident surface of the light guide plate; and a shade that, in a lateral view of the light guide plate and the LED unit, covers a gap between the LED unit and the light guide plate, and seals a gap between the display panel and the support plate.

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 apparatus includes: a display panel; a back frame including a flat portion and a side wall; light sources arranged in rows and columns at substantially equal intervals in the flat portion; support pins arranged in rows and columns at substantially equal intervals in the flat portion and away from the light sources; a diffuser panel diffusely emitting light from the light sources toward the display panel; and a luminance-equalizing sheet that is supported on the support pins, between the diffuser panel and the back frame, has an outer edge substantially overlapping an outer edge of an active area of the display panel, and transmits part of the light from the light sources toward the diffuser panel. The luminance-equalizing sheet protrudes in a curved manner toward the side wall between the diffuser panel and the side wall such that distance to the back frame gradually decreases outward.

Abstract: An image display apparatus includes a display panel including a front surface on which an image is displayed, a base plate disposed behind the display panel, a light guide plate disposed between the display panel and the base plate, a light source, a light source cover, and a corner component. The light source is disposed along an edge of the base plate, and emits light incident on an edge face of the light guide plate. The light cover is elongated and covers a front of the light source. The corner component is disposed along a corner of the base plate, laterally supports the display panel, and includes a portion that overlaps the light source cover in a front to back direction.
