PCT No. PCT/JP96/00233 Sec. 371 Date Aug. 6, 1997 Sec. 102(e) Date Aug. 6, 1997 PCT Filed Feb. 5, 1996 PCT Pub. No. WO96/25020 PCT Pub. Date Aug. 15, 1996This invention provides a multi-color light emission apparatus wherein a transparent inorganic oxide substrate (4) is disposed between an organic EL device (1) and a fluorescent layer (3) in such a manner as to arrange the fluorescent layer (3) with a gap with the organic EL device (1), and the organic EL device (1) is sealed by sealing means (5) between the transparent inorganic oxide substrate (4) and a support substrate (2). The invention provides also a multi-color light emission apparatus wherein a transparent insulating inorganic oxide layer (12) having a thickness of 0.01 to 200 mu m is interposed between the fluorescent layer (3) and the organic EL device (1). In this way, light emission life and angle-of-view characteristics can be improved.
