Zusammenfassung:	An image display apparatus (10) includes: a display panel (102); a back frame (111) including a flat portion (111A) and a side wall (111B); light sources (113) arranged in rows and columns at substantially equal intervals in the flat portion (111A); support pins (112) arranged in rows and columns at substantially equal intervals in positions in the flat portion (111A) and away from the light sources (113); a diffuser panel (106) diffusely emitting light from the light sources (113) toward the display panel (102); and a luminance-equalizing sheet (107) that is supported at intermediate positions on the support pins (112), between the diffuser panel (106) and the back frame (111), has an outer edge that substantially overlaps an outer edge of an active area of the display panel (102), and transmits part of the light from the light sources (113) toward the diffuser panel (106). The luminance-equalizing sheet (107) protrudes in a curved manner toward the side wall (111B) between the diffuser panel (106) and the side wall (111B) such that distance between the luminance-equalizing sheet (107) and the back frame (111) gradually decreases from an outer edge of the flat portion (111A) to an outer edge of the side wall (111B).
