1. A display apparatus comprising:
a flexible circuit board comprising a driving chip, and further comprising flexible pads arranged in a first direction and substantially extending in a second direction crossing the first direction;
a main circuit board comprising main pads connected to corresponding flexible pads in a third direction that is perpendicular to both the first direction and the second direction; and
a display panel comprising a plurality of pixels connected to the flexible circuit board, wherein the plurality of pixels is configured to receive a signal from the driving chip,
wherein, in each of the flexible pads and the main pads, a portion of each main pad and each corresponding flexible pad is tilted such that the tilt increases from a main pad and corresponding flexible pad disposed at a center area to a main pad and corresponding flexible pad disposed at an outer side, and
a tilted angle of a main pad disposed at the outermost side of the main circuit board is greater than a tilted angle of a corresponding flexible pad disposed at the outermost side of the flexible circuit board.
