摘要： A method and apparatus for manufacturing EL devices in a short period of time wherein during formation of a light emitting layer composed of II, III or VI-group of elements doped with a light emitting element through a chemical vapor deposition method, water content of a transport gas that transports gasified organic metals is removed through a dehydration filter and thus, source material decomposition due to the water content is prevented and a steady supply of source materials becomes possible. By removing the water content of the transport gas, source materials can be supplied constantly even if heating temperatures exceed a temperature conventionally regarded as the temperature at which decomposition starts and thus, a light emitting layer having a practical thickness can be formed in a short period of time. Because of the high-speed film formation, the rate of the film being contaminated with impurities lessens and the light emitting layer has a luminance three times that of conventional layers.

摘要： A luminescent layer in an EL device composed of CaGa.sub.2 S.sub.4 :Ce includes a first luminescent layer and a second luminescent layer. The first luminescent layer has an atomic ratio of Ga to Ca being higher than that in the second luminescent layer, and directly disposed on a first insulating layer, whereby delamination can be prevented. The atomic ratio of Ga to Ca in the second luminescent layer is approximately equal to a stoichiometric ratio, so that the threshold voltage of the EL device can be kept low.
