Abstract: A display apparatus includes a display panel and a touch sensing unit on the display panel. The touch sensing unit includes a plurality of first touch sensing parts arranged with each other along a first direction and having a mesh shape, a first connection part configured to connect adjacent ones of the first touch sensing parts to each other along the first direction, a plurality of second touch sensing parts arranged with each other along a second direction crossing the first direction and having the mesh shape, and a second connection part configured to connect adjacent ones of the second touch sensing parts to each other along the second direction. An insulation layer is located between the first connection part and the second connection part, and the first connection part extends to cross the adjacent ones of the second touch sensing parts.
