Abstract: Provided is a display apparatus. The display apparatus includes a flexible circuit board including flexible pads, a main circuit board including main pads, and a display panel including a plurality of pixels connected to the flexible circuit board and configured to receive a signal from the driving chip. In each of the flexible pads and the main pads, a portion of the pads is gradually tilted from pads disposed at a center to pads disposed at an outer side among the pads, and a tilted angle of a main pad disposed at the outermost side of the main circuit board is greater than that of a flexible pad disposed at the outermost side of the flexible circuit board.
