摘要： An image display device includes: an image display unit which includes a display panel switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel is in a transmissive state where an object behind the image display unit is visible in a front view of the display panel; a controller which controls an operation of the display panel; and a lower shelf board which is a holding member. The lower shelf board is disposed projecting rearward from a rear surface of the image display unit and holds the controller in a housed state.

摘要： A video display device includes: a display panel that displays an image based on an input image signal; a light source substrate that includes a plurality of light sources on a main surface which is a front side of the light source substrate, and emits, toward a rear side of the display panel, light emitted from the plurality of light sources; a reflection sheet that is provided on the main surface of the light source substrate, and in which hollow partitioning walls each of which separates adjacent two light sources of the plurality of light sources are formed; an optical member that is provided between the display panel and the light source substrate, and uniformizes luminance distribution of the light emitted from the light source substrate; and support members each of which is provided between the light source substrate and the optical member, and supports the optical member. The reflection sheet includes intersection portions where the partitioning walls formed in a first direction and the partitioning walls formed in a second direction crossing the first direction cross each other, and further includes linear portions formed in parallel with the first direction or the second direction. Each of the support members is disposed in a recess portion formed in a corresponding linear portion.

摘要： An image display device includes: a display panel which displays an image on a front surface of the display panel; a heat diffusing plate on a rear side of the display panel; and a frame along an edge surface of the display panel and an edge surface of the heat diffusing plate. The frame includes: a side wall which is disposed opposite to the edge surface of the display panel and the edge surface of the heat diffusing plate; and a support wall which projects from the side wall toward the heat diffusing plate. The heat diffusing plate includes a peripheral portion between the support wall and the display panel. The peripheral portion includes, on a rear side, a stepped portion which houses at least part of support wall.

摘要： An image display device includes an image display unit including a display panel, a shelf board, and an illumination unit. The display panel is switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel is in a transmissive state where objects behind image display unit is visible in a front view of the display panel. The shelf board is disposed projecting rearward from the rear surface of image display unit, and extends in the lateral direction. The illumination unit is disposed above the shelf board and emits light downward.

摘要： A video display device includes a liquid crystal display panel, and light source substrates configured to illuminate the liquid crystal display panel from a rear side of the liquid crystal display panel. Each of the light source substrates includes a plurality of light emitting diodes each of which is provided in corresponding one of areas different from each other in the liquid crystal display panel, and driver elements which drive each of the plurality of light emitting diodes such that light is emitted with luminance corresponding to brightness within a corresponding area of an image in accordance with a control signal. First conductive foil is disposed on a first main surface of the light source substrate on which the light emitting diodes are provided. Second conductive foil is disposed on a second main surface of the light source substrate on a side opposite to the first main surface. Ground pattern foil is disposed as the second conductive foil on the second main surface in regions each of which includes a corresponding one of the plurality of light emitting diodes in a plan view. The first conductive foil and the second conductive foil have a substantially equivalent area.
