Abstract
An image display apparatus includes: a display panel; a back frame including a flat portion having a substantially flat surface; light sources spaced substantially evenly apart in the flat portion; and a luminance-equalizing sheet supported at a distance from the light sources by support pins. The luminance-equalizing sheet includes through holes that transmit light from the light sources toward the display panel. The through holes are arranged in a predetermined pattern applied to blocks that are arranged in an array in the luminance-equalizing sheet and each of which faces a different one of the light sources. The predetermined pattern includes a first pattern and a second pattern. The first pattern is applied to at least some of outer blocks in contact with a periphery of the array, and the second pattern is applied to at least some of the blocks to which the first pattern is not applied.
