  • Patent number: 7348655
    Abstract: An organic electro luminescence device is provided. A thin film transistor (TFT) is formed within a sub-pixel region defined by a gate line and a data line on a substrate. A passivation layer and a first electrode are sequentially formed on the substrate where the TFT is formed. A contact hole is formed at a predetermined portion of the passivation layer and the first electrode so as to expose a drain electrode of the TFT. An electrode separator and a buffer layer are misaligned with the gate line by a predetermined position, such that an emission region corresponding to the sub-pixel and a region including the contact hole of the TFT are separated. An organic electro luminescent layer is formed within a region defined by the buffer region. A second electrode is formed on the organic electrode luminescent layer and is connected to the drain electrode of the TFT through the contact hole.

  • Publication number: 20080000420
    Abstract: Disclosed are a shadow mask and a deposition device having the same. The deposition device includes a shadow mask that has a plurality of openings, a chamber that has the shadow mask therein, a deposition cell disposed on a lower portion of the chamber, in which the deposition cell contains deposition materials, and a blocking member interposed between an inner side of the chamber and an outer side of the shadow mask so as to prevent the deposition materials from passing through between the inner side of the chamber and the outer side of the shadow mask. Deposition materials sublimated from a deposition cell are prevented from passing through the shadow mask, except for the openings of the shadow mask, so that the inside of a chamber can be prevented from being contaminated, thereby improving workability of a thin film deposition device. Deposition materials attached to the inside of the chamber can be prevented from being separated from the chamber, so the deposition materials cannot serve as particles.
