  • Publication number: 20080018241
    Abstract: An organic light emitting display device (OLED) includes a transparent substrate a first electrode formed on the transparent substrate a partition wall including first and second tapered structures having different tapers and formed on the first electrode, and an organic light emitting layer stacked on both sides of the first electrode below a level of the partition wall and a second electrode. The OLED device is manufactured by, for example, forming a first electrode on a transparent substrate, forming a partition wall having first and second tapered structures on the first electrode, and forming an organic light emitting layer and a second electrode, sequentially, on both sides of the first electrode below a level of the partition wall.

  • Publication number: 20070267633
    Abstract: Provided is a flat panel display device and a method for fabricating the same. The flat panel display device comprises a first substrate, a light emitting unit, a second substrate, and insulating films. The light emitting unit comprises thin film transistors positioned on the first substrate, a first electrode electrically connecting with the thin film transistors, a second electrode facing the first electrode, and an emission layer or a liquid crystal layer interposed between the first and second electrodes. The second substrate is sealed with the first substrate by an ultraviolet curing sealant, and has a greater thermal expansion coefficient than the first substrate. The insulating films are positioned on one or more surfaces of the first and/or second substrates.

  • Publication number: 20060061262
    Abstract: A dual panel-type organic electroluminescent display device includes a first substrate on which gate and data lines cross each other to define sub-pixels. Array elements are disposed at the sub-pixels on the first substrate. A first electrode is disposed on substantially the entire surface of a second substrate opposing the first substrate. An insulating pattern is disposed on the first electrode, an organic electroluminescent layer is disposed on the first electrode, and a second electrode is disposed on the organic electroluminescent layer at each sub-pixel. A connection pattern connects the array element and the second electrode at each sub-pixel. The connection pattern contacts the second electrode under the insulating pattern.
