## Abstract

A display apparatus including a display panel including a base substrate and a first pad electrode on a first pad portion of the base substrate, a flexible substrate connected to the first pad portion, and a driving chip electrically connected to the flexible substrate. The flexible substrate includes a first film layer, a first wiring layer on the first film layer and comprising a plurality of wirings, a second film layer on the first wiring layer, and a second wiring layer on the second film layer and comprising a plurality of wirings. The wirings of the second wiring layer include a first_first wiring and a first_second wiring, the first_first wiring and the first_second wiring extend in a same direction along a same line and are spaced from each other by a gap therebetween. The gap is at an edge of the base substrate in a plan view.
