A video display device comprising: a display panel that displays an image based on an image signal; a plurality of light source substrates disposed on a rear side of the display panel and arranged in a first direction, and in a second direction perpendicular to the first direction, each of the plurality of light source substrates including a plurality of light emitting elements and a plurality of driver elements (22, 23) for driving each of the plurality of light emitting elements; a reflection sheet, made of one piece and made of polypropylene, in which hollow partitioning wall portions are formed, each of partitioning wall portions separates adjacent ones of the light emitting elements, and expands toward the display panel, the reflection sheet covering the plurality of light source substrates on the side toward the display panel except for portions provided with the light emitting elements; wherein, for each of the plurality of light source substrates: the plurality of light emitting elements of said light source substrate is attached to a surface of said light source substrate on a side toward the display panel to emit light to the display panel; and the plurality of driver elements (22, 23) of said light source substrate is attached to said surface of said light source substrate on the side toward the display panel in a portion surrounded by the corresponding partitioning wall portions; and wherein the partitioning wall portions function as ribs, thereby increasing rigidity of the reflection sheet. a display panel that displays an image based on an image signal; a plurality of light source substrates disposed on a rear side of the display panel and arranged in a first direction, and in a second direction perpendicular to the first direction, each of the plurality of light source substrates including a plurality of light emitting elements and a plurality of driver elements (22, 23) for driving each of the plurality of light emitting elements; a reflection sheet, made of one piece and made of polypropylene, in which hollow partitioning wall portions are formed, each of partitioning wall portions separates adjacent ones of the light emitting elements, and expands toward the display panel, the reflection sheet covering the plurality of light source substrates on the side toward the display panel except for portions provided with the light emitting elements; wherein, for each of the plurality of light source substrates: the plurality of light emitting elements of said light source substrate is attached to a surface of said light source substrate on a side toward the display panel to emit light to the display panel; and the plurality of driver elements (22, 23) of said light source substrate is attached to said surface of said light source substrate on the side toward the display panel in a portion surrounded by the corresponding partitioning wall portions; and wherein the partitioning wall portions function as ribs, thereby increasing rigidity of the reflection sheet. the plurality of light emitting elements of said light source substrate is attached to a surface of said light source substrate on a side toward the display panel to emit light to the display panel; and the plurality of driver elements (22, 23) of said light source substrate is attached to said surface of said light source substrate on the side toward the display panel in a portion surrounded by the corresponding partitioning wall portions; and wherein the partitioning wall portions function as ribs, thereby increasing rigidity of the reflection sheet.
