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: A video display device includes a display panel that displays an image based on an image signal, and a light source substrate disposed on a rear side of the display panel. The light source substrate includes a plurality of light emitting elements disposed on a surface of the light source substrate on a side toward the display panel, and a plurality of driver elements that are disposed on the same surface of the light source substrate as the surface to which the plurality of light emitting elements are attached, and drive each of the plurality of light emitting elements.
