Abstract: A display apparatus includes a lower substrate, an upper substrate facing the lower substrate, an optical medium layer between the lower and upper substrates, a display area at which an image is displayed, and a peripheral area adjacent to the display area and at which the image is not displayed. The lower substrate includes a flexible film on a lower base substrate and including a flat portion in the display and peripheral area, and the flat portion extending from the peripheral area and along a side surface of the lower base substrate to define a bent portion in the peripheral area, a thin film transistor on the flexible film in the display area, a connecting line on the flexible film in the peripheral area and electrically connected to the thin film transistor, and a wire grid polarizer between the flexible film and the optical medium layer in the display area.
