    • It is an object of the present invention to provide a light emitting device having a structure wherein oxygen and moisture are prevented from reaching to the light emitting device, and to provide a manufacturing method thereof. It is another object of the present invention to seal a light emitting device in fewer steps without encapsulating a desiccant.
      The present invention provides a structure in which a pixel region 13 is surrounded by a first sealing material (having higher viscosity than a second sealing material) 16 including a spacer (filler, minute particles and/or the like) which maintains a gap between the two substrates, filled with a few drops of the transparent second sealing material 17a which is spread in the region; and sealed by using the first sealing material 16 and the second sealing material 17.
    • 本发明的目的是提供具有防止氧气和湿气到达发光器件的结构的发光器件,并提供其制造方法。 本发明的另一个目的是在不封装干燥剂的情况下以更少的步骤密封发光器件。 本发明提供一种结构,其中像素区域13被包括隔离物(填充物,微小颗粒等)的第一密封材料(具有比第二密封材料更高的粘度)16包围,所述隔离物保持 两个基板,填充有数滴在该区域中展开的透明第二密封材料17a; 并通过使用第一密封材料16和第二密封材料17进行密封。
