Abstract

A video display device includes: a display panel that displays an image based on an image signal; a light source substrate disposed on a rear side of the display panel; a plurality of light emitting elements each of which is attached to a surface of the light source substrate on a side toward the display panel to emit light to the display panel; a reflection sheet; and driver elements that drive each of the plurality of light emitting elements. Partitioning wall portions are formed in the reflection sheet, each of partitioning wall portions separates adjacent ones of the light emitting elements, and expands toward the display panel. The reflection sheet covers the surface of the light source substrate on the side toward the display panel except for portions provided with the light emitting elements. Each of the driver elements is attached to the surface of the light source substrate on the side toward the display panel in a portion surrounded by the corresponding partitioning wall portions.
