Patent ID: 10809569

Abstract:
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.
