An organic electroluminescent (EL) display device and a method of manufacturing the same. The organic EL device includes a substrate layer, a first electrode layer formed on the substrate layer, an organic layer formed on the first electrode layer, and a second electrode layer formed on the organic layer, wherein a light loss preventing layer having different refractive index areas is formed between layers of the organic EL device having a large difference in refractive index among the respective layers.

A semiconductor laser CRT for driving at room temperature, whose target is pumped by an electron beam, in which a laser target is fixed to a beaker-shaped transparent glass support plate, and the glass support plate is sealed with a glass bulb using fused frit glass. Accordingly, there is no cracking of the glass bulb due to a difference in thermal expansion or destroying of a sustained airtight vacuum.
