Abstract: A flexible display apparatus includes a flexible display panel including a flexible substrate, a display area of the flexible substrate including a thin film transistor, an organic light emitting layer and a sensor electrode, and a peripheral area of the flexible substrate including a first alignment mark in which respective portions of two metal layers are stacked; a window on a first surface of the flexible display panel; and a protective film on a second surface of the flexible display panel. The first alignment mark is aligned with a reference point of the window and with a reference point of the protective film.

Abstract: A display device includes a window combined with a substrate. The substrate includes a display region with pixels and a non-display region with power lines for the pixels. The window includes a display part corresponding to the display region and a non-display part corresponding to the non-display region. A plurality of alignment marks are on the substrate at a location corresponding to the non-display region. The alignment marks are integrally provided with an outermost power line at an outermost side of the non-display region, and each of the alignment marks overlaps with the non-display part of the window.
