PURPOSE: A casing unit for encapsulating elements and a manufacturing method thereof are provided to reduce the manufacturing cost of the casing unit by employing a casing provided with a capsule at which getter is disposed. CONSTITUTION: An air-tight casing unit is provided with capsules for accommodating an organic light-emitting diode display and getter(6) for absorbing impurities in the air. An internal surface of the respective capsules has a large structure(8a) and/or a small structure(8b). The getter(6) is directly disposed at the internal surface. The large structure(8a) is a crater, cone, or column shape surface structure that ranges from 1 to 500μm in size. The small structure(8b) is a crater, cone, or column shape surface structure that ranges from 1 to 1000nm in size. |
