Abstract:
1. A flat panel display apparatus comprising: a substrate; a display unit disposed on the substrate to realize an image; a metal sheet which is disposed opposite to the substrate, wherein the metal sheet covers at least a part of the display unit, and is wrinkled at a central part to form uneven wrinkles and is not wrinkled at an edge part to form a flat shape, and wherein the metal sheet is formed as one body and has substantially constant thickness; and a sealing material in the space between the substrate and the metal sheet that seals the substrate and the metal sheet; a polymer layer, comprising at least one of polyethyleneterephthalate, polyethylenenylon, and polyimide, which is disposed on a surface of the metal sheet and has a lower coefficient of thermal expansion (CTE) than the CTE of the metal sheet; wherein the uneven wrinkles overlap at least a portion of the metal sheet in a direction perpendicular to the metal sheet.
