Abstract: A foldable glass substrate includes a top surface, a bottom surface, and a side surface. The side surface includes a first side surface extending at a first angle from the top surface, a second side surface extending at a second angle from the bottom surface, and a third side surface extending from each of the first side surface and the second side surface. A length of the third side surface in a direction substantially perpendicular to at least one of the top surface and the bottom surface is equal to or greater than about 0.3 times and equal to or less than about 0.7 times of a minimum distance between the top surface and the bottom surface. The minimum distance is equal to or greater than about 15 micrometers (μm) and equal to or less than about 100 μm.

Abstract: A thin film transistor is disposed on a substrate. A via insulating layer having a via hole covers the thin film transistor. A pixel electrode is disposed on the via insulating layer and electrically connected to the thin film transistor through the via hole. A first protection layer surrounds the pixel electrode. A pixel-defining layer covers an edge region of the pixel electrode and at least a portion of the first protection layer. The pixel-defining layer includes an opening through which an upper surface of the pixel electrode is exposed. An opposite electrode faces the pixel electrode. An intermediate layer is disposed between the pixel electrode and the opposite electrode.
