Abstract: A display apparatus includes: a substrate including a thin-film transistor including an electrode, a non-display area, and a pad area including a lower and an upper conductive layer facing each other with an insulating layer therebetween. The lower conductive layer includes: a first conductive layer defining an end surface of the display apparatus, and a second conductive layer spaced apart from the first conductive layer to define a space between the first and second conductive layers, the insulating layer defines a first opening portion corresponding to the space, and the upper conductive layer is in a same layer as the electrode of the thin-film transistor, the upper conductive layer extending into the first opening portion corresponding to the space between the first and second conductive layers.

Abstract: A display device includes a base substrate including: a display region including a pixel, and a pad region defining an end surface of the base substrate which is furthest from the display region and exposed outside the display panel; an insulating layer in the display region and the pad region; and in the pad region: a signal pad electrically connected to the pixel and to a dummy pad; the insulating layer covering the signal pad and the dummy pad and defining an end surface of the insulating layer which is furthest from the display region and exposed outside the display panel; and a first opening in the insulating layer which exposes the signal pad outside the insulating layer and outside the display panel. In the pad region, the end surfaces of the base substrate and the insulating layer together define an inclined edge of the display panel.
